    This is for your personal safety!

    1. Safety rules

    Environmental conditions

    Operation or storage of the device outside the stipulated area will be deemed as not in accordance with the intended purpose. The manufacturer accepts no liability for any damage resulting from improper use.

    1. Safety rules

    Qualified personnel

    The servicing information contained in these operating instructions is intended only for the use of qualified service engineers. An electric shock can be fatal. Do not carry out any actions other than those described in the documentation. This also applies to qualified personnel.

    All cables and leads must be secured, undamaged, insulated and adequately dimensioned. Loose connections, scorched, damaged or inadequately dimensioned cables and leads must be immediately repaired by authorised personnel.

    Maintenance and repair work must only be carried out by an authorised specialist.

    It is impossible to guarantee that bought-in parts are designed and manufactured to meet the demands made on them, or that they satisfy safety requirements. Use only original spare parts (also applies to standard parts).

    Do not carry out any alterations, installations, or modifications to the device without first obtaining the manufacturer's permission.

    Components that are not in perfect condition must be changed immediately.

    1. Safety rules

    Noise emission values

    The maximum sound power level of the inverter is specified in the Technical Data.

    The device is cooled as quietly as possible with the aid of an electronic temperature control system; this depends on the amount of converted power, the ambient temperature, the level of soiling of the device, etc.

    It is not possible to provide a workplace-related emission value for this device because the actual sound pressure level is heavily influenced by the installation situation, the power quality, the surrounding walls and the properties of the room in general.

    1. Safety rules

    EMC measures

    In certain cases, even though a device complies with the standard limit values for emissions, it may affect the application area for which it was designed (e.g., when there is equipment that is susceptible to interference at the same location, or if the site where the device is installed is close to either radio or television receivers). If this is the case, then the operator is obliged to take action to rectify the situation.

    1. Safety rules

    Emergency power

    This system is equipped with an emergency power function. This means a backup power supply is automatically established in the event of a power outage.

    The emergency power sticker provided with the inverter must be attached to the electrical distributor.

    For maintenance and installation work, the system must both be isolated from the grid, and backup power mode must be disabled by opening the integrated DC disconnector on the inverter.

    The emergency power supply is automatically activated and deactivated depending on the insolation conditions and the state of charge of the battery. This means that emergency power can be re-established unexpectedly when in standby mode. For this reason, when the emergency power supply is deactivated, switch off all connected devices and do not undertake any installation work on the household network.

    The hybrid inverter converts the direct current generated by the PV modules into alternating current. This alternating current is synchronized with the grid voltage and fed into the public grid. Moreover, the solar energy can also be stored in a connected battery for later use.

    The hybrid inverter has been developed specifically for use in grid-connected photovoltaic systems. A backup power mode is possible if the cabling is set up accordingly.

    Thanks to its design and operating principle, the inverter is extremely safe both to install and to operate.
    The inverter monitors the public grid automatically. In the event of abnormal grid conditions, the inverter ceases operating immediately and stops feeding power into the grid (e.g. if the grid is switched off, if there is an interruption, etc.).
    The grid is monitored by monitoring the voltage, frequency and islanding conditions. The inverter switches to backup power mode if it has been cabled up accordingly.

    Operation of the inverter is fully automatic.
    The inverter is designed to draw as much power from the PV modules as possible.
    Depending on the operating point, this power is either stored in the battery, fed into the grid or used for the household network in backup power mode.

    As soon as the energy provided by the PV modules is no longer sufficient, the power from the battery is fed into the home. Depending on the setting, power may also be obtained from the public grid in order to charge the battery.

    If the inverter becomes too hot, it automatically reduces the current output power or charging power, or switches to backup power mode in order to protect itself.
    Reasons for the inverter becoming too hot include the ambient temperature being too high or inadequate heat dissipation (e.g. if it is installed in a switch cabinet without suitable heat dissipation).

    IMPORTANT! The battery must only be switched on when the inverter is in Standby mode.

    Proper use

    The solar inverter is exclusively intended for charging a battery with direct current from solar modules, or for converting this direct current into alternating current and feeding it into the public grid or the household network in emergency power mode.
    The following actions constitute improper use:
    • Any use above and beyond this purpose
    • Making any modifications to the inverter that have not been expressly approved by Fronius
    • Installing components that are not distributed or expressly approved by Fronius
    • Operating the device with a battery that has not been approved by Fronius
    • Operating the equipment with an energy meter that has not been approved by Fronius

    Fronius shall not be liable for any damage resulting from such action.
    No warranty claims will be entertained.

    Proper use also includes:
    • Carefully studying and obeying the Installation and Operating Instructions
    • Performing all stipulated inspection and maintenance work

    When designing the photovoltaic system, ensure that all of its components are operated within their permitted operating ranges at all times.

    Observe all the measures recommended by the solar module manufacturer to ensure that the solar module retains its properties in the long term.

    Observe the stipulations of the power supply company concerning energy fed into the grid, emergency power mode and the operation of storage systems.

    The Fronius Symo Hybrid is a grid-connected inverter with an emergency power function – it is not a stand-alone inverter. The following restrictions must therefore be observed in emergency power mode:
    • Emergency power mode may be in operation for at least 1500 hours
    • Emergency power mode may be in operation for more than 1500 operating hours if 15% of the duration of the inverter's grid power feed operation is not exceeded at the relevant time

    With the market launch of its new Fronius Energy Package, Fronius is introducing an inverter that can be used to store energy. One of the key components is the Fronius Solar Battery, which contains a lithium-ion rechargeable cell. The Fronius Solar Battery supplements the Fronius hybrid inverter by adding storage functionality. This means that the solar energy from the solar modules can be stored for later use.
    The storage system is only suitable for operation in conjunction with Fronius hybrid inverters.

    Thanks to its design and operating principle, the storage system is extremely safe both to install and to operate. A high-performance lithium-ion phosphate battery is used (LiFePO4), which is based on the latest technology and complies with the highest safety standards.

    When used in conjunction with the Fronius inverter, operation of the storage system is fully automatic.

    If proper charging of the batteries in the Fronius Energy Package cannot be guaranteed for an extended period of time (over several weeks or months) for any reason, we strongly recommend that the following steps are undertaken to prevent the deep discharge of the battery modules:
    • switch off the main switch of the Fronius Solar Battery
    • remove the DC fuses from the fuse holder
    • remove the orange power connector from the individual battery modules

    Battery module (1.2 kWh usable capacity)

    With the market launch of its new Fronius Energy Package, Fronius is introducing an inverter that can be used to store energy. One of the key components is the Fronius Solar Battery, which contains a lithium-ion rechargeable cell. The Fronius Solar Battery supplements the Fronius hybrid inverter by adding storage functionality. This means that the solar energy from the solar modules can be stored for later use.
    The storage system is only suitable for operation in conjunction with Fronius hybrid inverters.

    Thanks to its design and operating principle, the storage system is extremely safe both to install and to operate. A high-performance lithium-ion phosphate battery is used (LiFePO4), which is based on the latest technology and complies with the highest safety standards.

    When used in conjunction with the Fronius inverter, operation of the storage system is fully automatic.

    If proper charging of the batteries in the Fronius Energy Package cannot be guaranteed for an extended period of time (over several weeks or months) for any reason, we strongly recommend that the following steps are undertaken to prevent the deep discharge of the battery modules:
    • switch off the main switch of the Fronius Solar Battery
    • remove the DC fuses from the fuse holder
    • remove the orange power connector from the individual battery modules

    2. Emergency power mode

    Restrictions in backup power mode

    In backup power mode, some electrical appliances cannot function properly as the starting currents are too high (e.g. fridges and freezers). It is recommended to switch off non-essential loads during backup power mode.

    Switching from grid-connected operation to backup power mode takes a little while. For this reason, the battery system with backup power function cannot be used as an uninterruptible power supply, for example for computers.

    If no energy is available from the battery or the PV modules during backup power mode, this mode is automatically ended, irrespective of whether power is available from the public grid or not.
    Fronius Solar Battery: If sufficient energy becomes available from the PV modules once again, backup power mode starts again automatically.
    BYD Battery-Box Premium: The system must be restarted manually as soon as sufficient energy from the PV modules or the public grid is available again. For the correct power-up sequence, see chapter BYD Battery-Box Premium on page (→).

    If consumption is too high, backup power mode is interrupted and status code "143 - Backup power overload" appears. The maximum power in backup power mode according to the technical data must be observed!

    2. Emergency power mode

    Backup power and energy saving mode

    If the inverter is operating in backup power mode, energy saving mode is automatically active. Under the following conditions, the battery and the inverter are switched to energy saving mode after a waiting time of 8 - 12 minutes:
    • The battery is discharged to the minimum state of charge and no energy is coming from the PV modules.
    • The inverter is in an error state that is not acknowledged automatically (e.g. multiple overload).
    • The inverter is set to energy saving mode (standby mode) using the display setting.
    If the battery and inverter are in energy saving mode, the system is reactivated by the following actions (applies only for Fronius Solar Battery):
    • Enough energy is available from the PV modules.
    • The public grid is functioning again.
    • The battery's POWER switch is switched off and on.

    Fronius Ohmpilot and backup power mode

     The Fronius Ohmpilot is not suitable for backup power mode. If a Fronius Ohmpilot is used, it should be installed outside of the backup power circuit (see Operating mode - Inverter plus battery, Ohmpilot and emergency power function on page (→)).

    NOTE!

    Risk from an active Ohmpilot in backup power mode.

    This may result in loss of the backup power supply.

    Never turn on boost mode on the Ohmpilot.

    Switch off the automatic circuit breaker on the Fronius Ohmpilot (if fitted).

    Before a power outage occurs, any function that would exceed the power limits in backup power mode must be disabled.

    Disable functions that would exceed the power limits in backup power mode:
    1Set measuring of heating rod to manual on the Ohmpilot (under "General - General Settings - Heating 1 - Manual").
    2Disable the "Legionella prevention (h)" and "Adapt day curve" settings (under "General - General Settings - Heating 1").

    Fronius Solar Battery and Fronius Symo Hybrid switch-off conditions

     

    The battery state of charge is less than or equal to the input minimum state of charge.

     

    The power from the PV modules is less than 50 W.

     

    The current charging or discharging power of the battery is less than 100 W.

     

    Less than 50 W is available for charging the battery. The power of feeding in for the public grid is at least 50 W less than the power currently required in the home network.

    If all the switch-off conditions are met, the battery switches into energy saving mode within six minutes. This time delay ensures that the inverter can be restarted at least once.

    The inverter automatically switches into energy saving mode after the battery.

    Backup power:
    If the backup power function has been activated, the battery in grid operation does not switch to energy saving mode. Otherwise, the dark start (start without grid and PV supply) of the hybrid system cannot be ensured.
    During backup power mode and when the state of charge falls below the minimum limit, the battery switches to energy saving mode.

    Fronius Symo Hybrid and Fronius Solar Battery switch-on conditions

    If one of the following conditions is met for at least 30 seconds, energy saving mode is ended:
    • Energy saving mode is no longer permissible owing to a changed setting on the user interface of the inverter.
    • More than 50 W is available for charging the battery. The power of feeding in for the public grid is at least 50 W greater than the power currently required in the home network.
    • If a dynamic power reduction of 0 is set, or if the system is operating in backup power mode, the power of feeding in for the public grid is always less than the required power in the home network.
      There is a separate condition for this case (dynamic power reduction < 300 W or active backup power mode): If the PV power is above a specified threshold (50 W), the energy saving mode is ended.
    • Battery charging from the public grid is requested via the website.
    • The battery is recharged to restore the minimum state of charge or to perform a calibration.
    • The Fronius Solar Battery is woken up as soon as the Symo Hybrid is generating PV power. This guarantees reliable operation of the battery.

    Calibration charging for the Fronius Solar Battery

    Benefits of calibration charging

    Natural differences in the individual cell capacities and the small amount of self discharge that occurs in all batteries cause the cell voltages to diverge. This makes the SOC value less accurate, which affects the operation. If no steps are taken, the battery will become damaged.

    Periodic calibration charging brings all cells of the battery to the same state of charge, and calibrates the SOC value. This ensures a longer service life of the battery cells.

    2. Calibration charging for the Fronius Solar Battery

    General

    Determining the exact state of charge (SOC) of the battery is important for operation management. To ensure this happens, the battery must regularly be charged to 100%. This allows the SOC value to be calibrated.

    Fronius Solar Battery:
    Calibration charging occurs automatically during operation after several charge and discharge cycles. When calibration charging is carried out depends on two crucial factors:
    • Average state of charge
    • Energy throughput of the battery

    As these factors are extremely weather dependent, the time of a calibration charge can vary depending on the time of year.

    The following description of calibration charging is valid from version 1.4.1-12 of the Fronius system monitoring software.

    1. General information
    2. Calibration charging for the Fronius Solar Battery

    Conditions for starting the calibration charge (Fronius Solar Battery)

    One charge and discharge cycle of the Fronius Solar Battery corresponds to an energy throughput of 48 Ah per battery module. Calibration charging occurs cyclically according to the following conditions:
    • After 3 full charge and discharge cycles and a SOC of 80%
    • After 5 full charge and discharge cycles and a SOC of 50%
    • After 7 full charge and discharge cycles, independent of the SOC

    For newly installed systems and for module replacement or expansion, a calibration charge is started automatically after 30 minutes.

    1. General information
    2. Calibration charging for the Fronius Solar Battery

    Calibration charging procedure (Fronius Solar Battery)

    Calibration charging primarily occurs with the entire PV power. If insufficient PV energy is available, energy is drawn from the public grid. This is also the case even if the "Battery charging from DNO grid" function is deactivated, as this is a critical requirement.

    The SOC is calculated per battery module. For this reason, each battery module must reach a SOC of 100%.

    1. General information
    2. Calibration charging for the Fronius Solar Battery

    Calibration process (Fronius Solar Battery)

    1. The start conditions must be fulfilled
    2. The battery is charged to 100% with a minimum current of 6.5 A or the total PV power.
    3. So that a SOC of 100% can be reached for each battery module, one of the following two conditions must be fulfilled for at least 2 minutes (for each cell in every battery module):
      • Minimum cell voltage ³ 3.45 V and current < 100 mA
      • Minimum cell voltage > 3.5 V independent of current
    4. When a battery module reaches one of these conditions, the current is limited to prevent an overload. A current in the two-digit mA range flows over a bypass resistor
    5. Unneeded PV power is reused directly
    6. Once all cells in all battery modules have fulfilled one of the two conditions, the SOC is set to 100% and calibration charging is complete.
    1. General information
    2. Calibration charging for the Fronius Solar Battery

    Duration of calibration charging (Fronius Solar Battery)

    Due to tolerances in the cells, they are not always charged and discharged at the same rate. As cells and battery modules are connected in series and the slowest cell determines the charging and discharging duration, some calibration charges need more or less time.

    In rare cases, calibration charges or full charge cycles (depending on the time of year, e.g. in the winter months) can lead to large variations in the cell voltages in the battery modules. In calibration mode, one cell charges more quickly than the others. This cell then begins redistribution. The other cells can then only be charged with a reduced charging current. It takes longer for these cells to reach the target value.

    If the battery is regularly charged completely, calibration charges are rarely required. The cells are calibrated during every charge with 100% SOC.
    In the winter months. where there are few full charges and a lower energy throughput, calibration charges can take longer, as higher variations between the battery modules must be redistributed.

    1. General information
    2. Calibration charging for the Fronius Solar Battery

    Limitations during calibration (Fronius Solar Battery)

    • Drawing energy from the battery (discharging) is not possible
    • Self-consumption optimisation is disabled while calibration charging is in progress
    • Charging from the grid can still occur if the "Battery charging from DNO grid" function is not activated, as this process concerns system-relevant service charging
    • Zero feed-in continues according to the standard and service charging can even be started if you wish to expand or replace battery modules during calibration
    • Emergency power mode can be started – calibration charging is interrupted
    1. General information
    2. Calibration charging for the Fronius Solar Battery

    Display during calibration charge (Fronius Solar Battery)

    As soon as calibration charging starts, it becomes visible in Fronius Solar.web (current and energy balance view) or on the web interface of the Fronius Symo Hybrid inverter.

     

    In Fronius Solar.web or on the web interface of the inverter, the calibration charge information is displayed in the overview. Clicking on the battery symbol (see the image on the left) displays the information "The battery is in calibration mode"

    In the energy balance display in Solar.web, both the start and end of the calibration charge is displayed by changing the battery status ("Battery Mode: Normal → Calibrate" and "Battery Mode: Calibrate → Normal")
    The following graphic shows calibration charging of the Fronius Solar Battery in the energy balance view. At the start of calibration charging, the total PV production is used to charge the battery. From the point where one cell is fully charged, only a certain charging current is drawn by the battery. This charging current decreases towards 0 A as the cell voltage increases.

    As during normal operation, the status "charging" (CHG) is shown on the battery display and the relevant charging current in ampere is displayed. If the charging current drops to below 0.3 A, 0 A is shown on the display, even though calibration charging continues.

    In Fronius Solar.web, the SOC value for the entire battery is displayed. On the battery display, the SOC values of the individual battery modules can be viewed.

    Setting range

    Relay mode / Relay test / Switch-on point* / Switch-off point*

    * these are only shown if the "E-Manager" function has been activated under "Relay mode".

    Relay mode
    The following functions can be shown using relay mode:

    • Alarm function (Permanent / ALL / GAF)
    • Active output (ON / OFF)
    • Energy Manager (E-Manager)

    Setting range

    ALL / Permanent / GAF / OFF / ON / E-Manager

    Factory setting

    ALL

    Alarm function:

    ALL / Permanent:

    Switching the floating switch contact for permanent and temporary service codes (e.g. brief interruption to energy being fed into the grid, a service code occurs a certain number of times a day - can be adjusted in the "BASIC" menu)

    GAF

    As soon as GAF mode is selected, the relay is switched on. The relay opens as soon as the power stage set registers an error and goes from normally feeding energy into the grid to being in an error state. This means that the relay can be used for fail-safe functions.

    Application example
    It may be necessary to perform phase compensation when using a single-phase inverter at a multiphase site. If an error occurs on one or several inverters and the connection to the grid is broken, the other inverters must also be disconnected to maintain the phase balance. The "GAF" relay function can be used in conjunction with the Datamanager or an external protection device to recognise or signal that an inverter is not feeding in or is disconnected from the grid and to then disconnect the remaining inverters from the grid using a telecontrol command.

    Active output:

    ON:

    The floating NO contact is on all the time the inverter is in operation (as long as the display is not dark or is displaying something).

    OFF:

    The floating NO contact is off.

    1. Operation
    2. Menu items in the Set-up menu

    Energy Manager
    (under "Relay" menu item)

    The "Energy Manager" function can be used to activate the floating switch contact in such a way that it functions as an actuator.
    Thus, a load that is connected to the floating switch contact can be controlled by specifying a switch-on or switch-off point that depends on the power of feeding in.

    The floating switch contact is automatically switched off:

    • If the inverter is not feeding any power into the grid
    • If the inverter is manually switched to Standby mode
    • If the effective power is set to < 10% of the rated power

    To activate the "Energy Manager" function, select "E-Manager" and press the "Enter" key.
    When the "Energy Manager" function is running, the "Energy Manager" symbol will appear in the top left corner of the display:

    When the floating NO contact is off (open contact)

    When the floating NO contact is on (closed contact)

    To deactivate the "Energy Manager" function, select a different function and press the "Enter" key.

    Notes on setting up the switch-on and switch-off points
    The interface of the energy management relay always uses the output power of the inverter as a reference point, although this will not necessarily match what is generated by the PV system in the case of the hybrid system.
    If the difference between the switch-on and switch-off points is too small, or if there are fluctuations in effective power, the result may be multiple switching cycles
    To avoid frequent switching on and off, the difference between the switch-on and switch-off points should be at least 100 - 200 W.

    When choosing the switch-off point, the power consumption of the connected load should be taken into account.

    When choosing the switch-on point, the weather conditions and anticipated insolation should also be taken into account.

    Application example
    Switch-on point = 2000 W, switch-off point = 1800 W

    If the inverter is outputting 2000 W or above, then the floating switch contact on the inverter is switched on.
    If the inverter output falls to below 1800 W, the floating switch contact is switched off.

    Prerequisites for operation

    You must have a suitable internet connection to enable data to be exchanged smoothly over the internet:

    • For wired internet solutions, Fronius recommends a
        download speed of at least 512 kBit/s and an
        upload speed of at least 256 kBit/s.
    • For solutions that rely on mobile internet services, Fronius recommends 3G transmission as a minimum, plus a reliable signal.

    Even if these specifications are adhered to, there is still no guarantee that everything will run smoothly.
    High error rates during transmission, variable reception conditions or transmission dropouts can all have a detrimental effect on the online functionality of Fronius system monitoring.
    Fronius recommends testing any connections that meet the minimum requirements locally.

    A data volume of approx. 500 kB per hour is required to view the system on Fronius Solar.web or the Fronius Solar.web App.

    A certain data volume is also required to update the Fronius system monitoring firmware. This data volume depends on the size of the update package and therefore cannot be considered in the advance data volume calculation.

    If data is sent via a third-party service (e.g. push service), a large quantity of data may be involved.

    IMPORTANT! Fronius recommends a flat rate data connection to avoid high connection charges.

    General information for the network administrator

    Requirements

    NOTE! Knowledge of networking systems is required in order to configure Fronius system monitoring for the network.

    If you are integrating Fronius system monitoring into an existing network, you must adapt the address settings in line with the network.


    e.g.: Network address space = 192.168.1.x, subnet mask = 255.255.255.0

    • An IP address of between 192.168.1.1 and 192.168.1.254 must be assigned to Fronius system monitoring.
    • The selected IP address must not be in use on the network already.
    • The subnet mask must match that of the existing network (e.g. 255.255.255.0).

    If you want Fronius system monitoring to send service messages or to transmit data to Fronius Solar.web, you must enter a gateway address and a DNS server address. Fronius system monitoring uses the gateway address for the purpose of establishing an Internet connection. An example of a suitable gateway address would be the IP address of the DSL router.

    IMPORTANT!

    • Fronius system monitoring must never be assigned the same IP address as the PC/laptop itself!
    • Fronius system monitoring is not capable of connecting to the Internet on its own. In the case of a DSL connection, a router has to establish the Internet connection.

    General firewall settings

    DSL routers usually allow data to be sent over the internet and so do not normally have to be configured for this purpose.

    Server addresses for data transfer
    If a firewall is used for outgoing connections, the following protocols, server addresses and ports must be allowed for successful data transfer:
    • Tcp fronius-se-iot.azure-devices.net:8883
    • Tcp fronius-se-iot.azure-devices.net:443
    • Tcp fronius-se-iot-telemetry.azure-devices.net:8883
    • Tcp fronius-se-iot-telemetry.azure-devices.net:443
    • Udp sera-gen24.fronius.com:1194 (213.33.117.120:1194)
    • Tcp froniusseiot.blob.core.windows.net:443
    • Tcp provisioning.solarweb.com:443
    • Tcp cure-se.fronius.com:443
    • NTP 0.time.fronius.com
    • Tcp http://firmware-download.fronius.com:80
    • Upd/Tcp 0.time.fronius.com:123

    If existing firewall rules block the connection to the Fronius system monitoring function, the following firewall rules must be added:

     

    49049/UDP
    output

    80/TCP *)
    Input

    Sending of service messages

    x

    -

    Ability to connect to Datamanager via Fronius Solar.web

    x

    -

    Ability to connect to Datamanager via Fronius Solar.access or Fronius Solar.service

    -

    x

    Ability to access the Datamanager web page

    -

    x

    Configure the firewall so that data can be sent from the Fronius system monitoring IP address to port 49049/UDP of "fdmp.solarweb.com".

    *) We recommend only allowing access to the web interface of the Fronius system monitoring function from secure networks. If internet access is absolutely necessary (e.g. for service purposes within a defined time period), configure the network router in such a way that requests for any external port are redirected to port 80/TCP.
    Caution - the inverter will therefore be visible on the internet and at will be at an increased risk of network attacks.

    Starting for the first time

    IMPORTANT! In order to establish a connection to Fronius system monitoring, the end device in question (e.g. laptop, tablet, etc.) must be set up as follows:

    • "Obtain IP address automatically (DHCP)" must be activated
    1Switch the device to Service mode
    • Activate the WLAN Access Point via the Setup menu on the inverter

    The inverter establishes the WLAN access point. The WLAN access point remains open for 1 hour.

     

    Installation using a web browser

    2Connect the end device to the WLAN access point

    SSID = FRONIUS_239.xxxxx (4-8 digits)
    • Search for a network with the name "FRONIUS_239.xxxxx"
    • Establish a connection to this network
    • Enter the password 12345678
    (Alternatively, connect the end device and inverter using an Ethernet cable.)
    3Enter the following in the browser:
    http://datamanager
    or
    192.168.250.181 (IP address for WLAN connection)
    or
    169.254.0.180 (IP address for LAN connection)

    The Setup wizard start page is displayed.

    If you run the technician wizard, always remember to make a note of the assigned service password. This service password is required to enter settings in the "System overview" and "DNO Editor" menus as well as for advanced battery settings.
    If the technician wizard is not run, no specifications regarding power reduction are set and hybrid mode is not possible (charging and discharging of the battery)

    4Run the technician wizard and follow the instructions

    NOTE!

    Danger of deep discharge of an unactivated battery

    This may result in permanent damage to the battery.

    The Solar Web wizard needs to be run in order to activate the battery and, if necessary, the Smart Meter.

    5Run the Solar Web wizard and follow the instructions

    The Fronius Solar.start homepage
    or
    the Fronius system monitoring web page is displayed.

    1. Fronius system monitoring
    2. Installing Fronius system monitoring – Overview

    Information to help you work through the technician wizard

    The technician wizard consists of 5 steps:

    1. General
    General system data (e.g. system name) is entered here

    2. Service password
    Enter (and make a note of) the service password.

    3. IO assignment
    Settings for the IO interface are entered (see also General for IO assignment on page (→))

    4. System overview
    Settings for the entire PV system are entered (see also System overview on page (→))

    5. Dynamic power
    Settings for dynamic power reduction are entered (see also DNO Editor – Dynamic power reduction on page (→))

    Once you have worked your way through the technician wizard, an automatic process is triggered to calibrate all the components. This involves charging the Fronius Solar Battery fully. After that, the system automatically starts in the set operating mode.
    This calibration charging process is also performed automatically during actual operation after a number of charging and discharging cycles. When this calibration charge is performed depends on a number of different factors, such as the average state of charge or the energy throughput through the battery. The time can therefore vary depending on the time of year as well.

    If the "permit battery charging from DNO grid" setting is deactivated, this calibration charging process relies exclusively on energy from the photovoltaic system when operating under normal conditions. Depending on the insolation conditions and size of the systems concerned, the charging process can take a very long time.
    If the "permit battery charging from DNO grid" setting is activated, the calibration charging process is performed by drawing a constant current from the photovoltaic system and the DNO grid.

    IMPORTANT! The automatic process for fully charging the battery may result in energy being drawn from the DNO grid. The process can take several hours and cannot be aborted.

    1. Fronius system monitoring
    2. Installing Fronius system monitoring – Overview

    Testing backup power mode

    NOTE!

    Danger from immediate inverter operation in backup power mode without a connection to the grid having been previously established.

    During grid-connected operation, the inverter recognises and stores the direction of phase rotation in the household network.
    Without a grid connection, no information is available regarding the direction of rotation and the inverter feeds energy with a default direction of rotation.

    This can cause the three-phase consumers in the household network to experience errors.

    Backup power mode should be tested once it has been installed and set up for the first time. A battery state of charge of over 30% is recommended when in test mode.

    A description of how to perform the test operation can be found in the chapter "Backup power checklist" of the document "Fronius Energy Package - Examples of backup power switchover".

    Setting options:
    • "Obtain address" - statically
      The user needs to enter a fixed IP address for the Datamanager (system monitoring) and also defines the subnet mask, the gateway address and the DNS server address (from the provider).
    • "Obtain address" - dynamically
      The Datamanager (system monitoring) fetches the IP address from a DHCP server (DHCP = Dynamic Host Configuration Protocol).
      The DHCP server must be configured so that the same IP address is always assigned to the Datamanager (system monitoring). This means that you always know which IP address can be used to reach the Datamanager (system monitoring) datalogger.
      If the DHCP server supports the DNS dynamic updates function, a name can be assigned to the Datamanager (system monitoring) in the "Host name" field. As a result, the connection to the Datamanager (system monitoring) can be established using the name instead of the IP address.
      For example: Host name = sample_system, domain name = fronius.com
      The Datamanager (system monitoring) can be reached via the address "sample_system.fronius.com".

    Load management

    Energy management controlling priorities
    If additional components (e.g. battery, Ohmpilot) are available in the system, the priorities can be set here. Devices with a higher priority are activated first, followed by the others if surplus energy is available.

    Load management
    Up to four different load management rules can be defined. If the thresholds are the same, the rules are activated in sequence. During deactivation, it is the other way round; the last IO switched on is the first to be switched off. If the thresholds are different, the IO with the lowest threshold is switched on first, followed by the one with the second lowest threshold and so on.

    IOs which are controlled through the power produced are always at an advantage over the battery and Ohmpilot. This means an IO can switch itself on, resulting in the battery no longer being charged or the Ohmpilot no longer being activated

    An IO is only activated or deactivated after 60 sec.

    Control
    • Control via Energy Manager deactivated.
    • Control via Energy Manager is based on the power produced.
    • Control via Energy Manager is based on surplus power (with feed-in limits). This option can only be selected if a meter has been connected. Control via Energy Manger is based on the amount of energy actually fed into the grid.
    Thresholds
    • on: For entering an effective power limit as of which the output is to be activated
    • off: For entering an effective power limit as of which the output is to be deactivated.
    Duration
    • Field for activating the minimum running time per switch-on operation
    • Field for specifying the minimum amount of time that the output should remain activated for per switch-on operation.
    • Field for activating the maximum running time per day
    • Field for specifying the maximum total amount of time that the output should be activated for per day (allowing for several switch-on operations).

    IMPORTANT! Since the various models have different numbers of registers, switching the data type also changes the register addresses for all subsequent models.

    "Demo mode" - Demo mode is used to implement or validate a Modbus master. It enables inverter, energy meter and Fronius string control data to be read out, even if no device is actually connected or active. The same data is always returned for all registers.

    "Inverter control via Modbus"
    If this option is activated, the inverter can be controlled via Modbus. The "Restrict the control" selection box is displayed. The following functions are part of inverter control:
    • On/Off
    • Power reduction
    • Specification of a constant cos phi power factor
    • Specification of a constant reactive power value

    "Control priorities"
    The control priorities define which service takes priority during inverter control.
    1 = highest priority, 3 = lowest priority
    The control priorities can only be changed under the "DNO EDITOR" menu item.

    field. If inverter control is to be limited to one or more devices, use this field to enter the IP addresses of the one(s) that is/are allowed to send commands to the Fronius Datamanager. Use commas to separate multiple entries.

    Examples:
    • One IP address: 98.7.65.4 - Inverter may only be controlled by IP address 98.7.65.4
    • Multiple IP addresses: 98.7.65.4,222.44.33.1 - Inverter may only be controlled by IP addresses 98.7.65.4 and 222.44.33.1
    • IP address space could (for example) be specified as a range from 98.7.65.1 to 98.7.65.254 (CIDR notation) as follows: 98.7.65.0/24 - Inverter may only be controlled by IP addresses 98.7.65.1 to 98.7.65.254

    Own consumption optimization
    The Fronius hybrid inverter always controls the system by adjusting it in line with the target value set at the metering point. In the "automatic" operating mode (factory setting), an adjustment is made to 0 W at the feed-in point (maximum self-consumption).

    The target value also applies if a further source feeds into this metering point. However, in this case:
    • The Fronius Smart Meter must be installed at the feed-in point
    • It is necessary to activate battery charging by a further producer (see chapter Battery management on page (→))

    The self-consumption optimisation has lower priority than the battery control specifications.

    Battery management

    Battery charging/discharging limits:
    The battery charging / discharging limits can be set "automatically" or "manually".
    If they are set automatically, suitable values are selected for the battery.
    If they are set manually, values can be set in the "Max SoC" (maximum state of charge) and "Min SoC" (minimum state of charge) fields. The range of values that can be set differs depending on the battery. In backup power mode without a grid, the set values are not taken into account.
    IMPORTANT! The settings must be agreed with the battery manufacturer! Fronius accepts no liability for damage to third-party batteries.

    Battery control specification:
    Using the time-dependent battery control, it is possible to prevent or restrict the charging/discharging and to specify a defined value for charging/discharging.

    The battery is affected by external factors, such as calibration charging, permitting AC charging, inverter power limitation, control parameters via Modbus or self-consumption optimisation. The battery control specifications have the second lowest priority, following the self-consumption optimization, and it may be the case that these are not fulfilled due to other specifications.

    Without any battery control specifications, optimization is performed to establish the best possible degree of self-consumption. Self-consumption decreases when battery control specifications are defined.

    The following values can be selected in the column "regulation":
    • max charging power
      The battery is charged at no more than the power set in the field "power"
    • min charging power
      The battery is charged at no less than the power set in the field "power"
    • max discharging power
      The battery is discharged at no more than the power set in the field "power"
    • min discharging power
      The battery is discharged at no less than the power set in the field "power"

    The day and time window in which this regulation applies is defined in the columns "Day of the week" and "Time window". It is not possible to define a time window over midnight.
    Example: Two entries are needed to set a parameter of 22:00 to 06:00: '22:00 - 24:00' and '00:00 - 06:00'.

    Examples for the battery control specifications can be found in the following chapter.

    Calibration charging (only for Fronius Solar Battery)
    At regular intervals, the Fronius hybrid inverter automatically charges the Fronius Solar Battery until it is full for the purpose of calibrating all the components. This process can be started manually here.

    IMPORTANT! When calibration charging is activated, normal operation is interrupted and the system may draw energy from the distribution network operator's grid. The process can take several hours and cannot be aborted.

    Once calibration is complete, the system automatically reverts to the operating mode that was set originally.
    This calibration charging process is also performed automatically during actual operation after a number of charging and discharging cycles.

    If the "permit battery charging from DNO grid" setting is deactivated, this calibration charging process relies exclusively on energy from the photovoltaic system. Depending on the insolation conditions and size of the systems concerned, the charging process can take a very long time.
    If the "permit battery charging from DNO grid" setting is activated, the calibration charging process is performed by drawing a constant current from the photovoltaic system and the distribution network operator's grid.

    PV power reduction

    The battery control parameters make the generated energy as optimally usable as possible. However, situations may arise in which PV energy cannot be fully used due to battery control parameters.

    Example

     

    Fronius Symo Hybrid 3.0-S:

    3000 W

    (max. output power)

    Fronius Solar Battery 7.5

     

     

    Defined discharge

    3000 W

     

    PV power

    1000 W

     

    In this case, the inverter would need to reduce the PV power to 0 W, as the output power of the Fronius Symo Hybrid 3.0-S is max. 3,000 W and the device is already fully utilised through the discharging.

    Since it does not make sense to waste PV power, the power limitation for the battery control parameters is automatically adjusted so that no PV power is wasted. In the above example, this means that the battery is only discharged with 2,000 W, so that the 1,000 W of PV power can be used.

    Battery
    If a battery is connected to the Fronius hybrid inverter, it must be activated here.
    This setting can only be made when there is an active connection to a battery. If you are unable to make this setting, check whether the battery is switched on and whether the data connection has actually been established.

    Enabling battery charging from DNO grid
    If you want the battery to be charged from the public grid, you can activate this here. Depending on what is required by standards or the feed-in tariff rules, it may be necessary to deactivate the setting.
    This setting does not affect the charging of the battery by other producers within the home. It merely relates to the process of drawing charging energy from the public grid.
    Regardless of this setting, the battery will still be charged from the public grid if needed for service reasons (e.g. to protect against deep discharge)
    Fronius Checkbox 500V installed
    If a battery from the LG Chem ResuH series is connected, a Fronius Checkbox 500V must be installed and this option must be activated.
    Emergency power
    Emergency power mode can be activated or deactivated here. The emergency power functionality can only be activated once the required IO assignments have been configured for emergency power. The meter must be installed at the feed-in point and configured.
    External producer
    If further decentralised producers are installed in the household and have been integrated into the self-consumption rule for the Fronius hybrid inverter, you must activate this setting. This means that energy can be drawn from the household network and fed into the battery via the Fronius hybrid inverter.
    You can restrict how much power is consumed by the Fronius hybrid inverter by specifying a maximum AC power value (AC max.). The maximum power consumption is limited to the AC nominal output of the Fronius hybrid inverter.
    Meter
    To ensure smooth operation in conjunction with other energy producers and in emergency power mode, it is important to install the Fronius Smart Meter at the feed-in point. The Fronius hybrid inverter and other producers must be connected to the public grid via the Fronius Smart Meter.
    This setting also affects how the Fronius hybrid inverter behaves overnight. If the function is deactivated, the inverter switches to Standby mode as soon as there is no more PV power available, provided that no energy management command is sent to the battery (e.g. minimum state of charge reached). The message "Power low" is displayed. The inverter restarts as soon as an energy management command is sent or there is sufficient PV power available.
    If the function is activated, the inverter remains permanently connected to the grid so that energy can be drawn from other producers at any time.
    Once the meter is connected, its position must be configured in the Fronius Datamanager.
    Several Fronius Smart Meters can be installed in the system. A different address needs to be set for each Smart Meter.
    The Watt value on the generator meter is the sum of all generator meters. The Watt value on the consumption meter is the value of all consumption meters.

    DNO Editor – Dynamic power reduction

    Electricity retailers or grid operators may stipulate feed-in limitations for an inverter (e.g. max. 70% of kWp or max. 5 kW).
    Dynamic power reduction takes account of self-consumption by the household before the power of an inverter is reduced:

    • A custom limit can be set.
    • A Fronius Smart Meter can be connected to the D- / D+ connection sockets for Modbus data on the system monitoring datalogger.

    With the Fronius Symo Hybrid, any PV power that is not allowed to be fed into the grid is used to charge the battery instead so that it does not go to waste. Dynamic power reduction is only activated if the battery is full or cannot be charged for some other reason.

    "No limit" - The photovoltaic system converts all the available PV energy and feeds it into the grid.

    "Limit for entire system" - The entire photovoltaic system is limited in accordance with a set power limit.

    Field for entering the total DC system power in Wp.
    This value serves as a reference for the rule and also for failures (e.g. a meter failure).

    Field for entering the max. power in W or % (up to two decimal places, negative values can also be entered).
    If no meter has been selected under the "Meter" menu item:
    Max. power produced by the entire system.
    If "Fronius Smart Meter" or S0 inverter has been selected under the "Meter" menu item: Max. grid power feed

    Example: Dynamic power reduction
    (efficiency values have not been taken into account)

    PV system to Fronius Symo Hybrid:

    5000 W

     

    Household consumption:

    1000 W

     

    Max. grid power feed:

    60% = 3000 W

     

     

     

     

    Case 1: The battery may be charged

     

     

    Power at grid feed-in point:

    0 W

     

    Power at inverter output:

    1000 W

     

    Power to the battery:

    3000 W

     

     

     

     

    Case 2: The battery must not be charged

    Power at grid feed-in point

    3000 W

     

    Power at inverter output:

    4000 W

     

    Power to the battery:

    0 W

     

     

     

     

    In this example, no more than 3000 W may be fed into the grid at the grid feed-in point. However, any loads that are located between the inverter and the grid feed-in point can be supplied by additional power from the inverter. These loads are also compensated as required.

    If you want the battery to be charged from the public grid, you can activate this here. Depending on what is required by standards or the feed-in tariff rules, it may be necessary to deactivate the setting.
    This setting does not affect the charging of the battery by other producers within the home. It merely relates to the process of drawing charging energy from the public grid.
    Regardless of this setting, the battery will still be charged from the public grid if needed for service reasons (e.g. to protect against deep discharge)

    Status codes – Class 1

    Class 1 status codes generally only arise momentarily and are caused by the public grid.

    Example: The grid frequency is too high and the inverter may not feed any energy into the grid owing to a standard. There is nothing wrong with the device.
    The initial response of the inverter is to disconnect itself from the grid. The grid is subsequently checked during the stipulated monitoring period. If no further problem has been detected by the end of this period, then the inverter will resume feeding energy into the grid.

    The GPIS SoftStart function is activated according to the country setup:
    After cutting out due to an AC error, the output power of the inverter is continuously increased in line with the national guidelines.

    Error message – Data converter

    If the data converter detects an error, the “State” LED lights up steady red to signal that an error has occurred. At the same time, the associated error messages are displayed via the “Error No” LEDs in accordance with table below. There are two different error categories:
    Serious errors (1 - 5): In this case, the data converter has to be switched off and then back on again. If the error recurs, the data converter must be replaced and sent away for repair.
    Warnings (6 - 15): These warnings are displayed for information only. They appear for 1 minute and are then reset automatically. If these warnings occur quite frequently, Customer Services should be notified accordingly.

    These displays are not applicable in Configuration mode and are intended for internal purposes only.

    Undefined operating statuses

    Battery switches off during start-up procedure:
    Keep the battery switched off for at least 120 minutes and then switch it on again. If this does not resolve the error, notify Customer Services.

    Battery switched off with a SOC (state of charge) of 0%:
    Communication error – Disconnect the inverter on the DC side and isolate it from the grid on the AC side. Wait 5 minutes and then reconnect the inverter on both the DC and AC sides. If this does not resolve the error, notify Customer Services.

    Battery active, state of charge (SOC) is more than 90% and red LED is flashing:
    Battery charging error – Disconnect the inverter on the DC side and isolate it from the grid on the AC side. Wait 30 minutes and then reconnect the inverter on both the DC and AC sides. If this does not resolve the error, notify Customer Services.

    Battery not charging or discharging (SOC indicated on web interface does not match that of the battery):
    Check whether battery is switched on – If it is not, switch it on.
    If it is, there is a communication error – Disconnect the inverter on the DC side and isolate it from the grid on the AC side. Wait 5 minutes and then reconnect the inverter on both the DC and AC sides. If this does not resolve the error, notify Customer Services.

    Battery no longer being displayed on web interface (triangular view instead of square view):
    Check whether battery is switched on – If it is not, switch it on.
    If it is, there is a communication error – Disconnect the inverter on the DC side and isolate it from the grid on the AC side. Wait 5 minutes and then reconnect the inverter on both the DC and AC sides. If this does not resolve the error, notify Customer Services.

    Whenever an error message of any kind appears on the battery display:
    Disconnect the inverter on the DC side and isolate it from the grid on the AC side. Wait 5 minutes and then reconnect the inverter on both the DC and AC sides. If this does not resolve the error, notify Customer Services.

    Unusual increase in temperature or strange smells:
    Switch off the system (battery main switch, DC side of inverter), ventilate the room and inform Customer Services.

    Applicable standards and guidelines

    Fronius hybrid inverter:

    CE mark
    The devices conform to all the requisite and relevant standards and guidelines that form part of the relevant EU directive, and are therefore permitted to display the CE mark.

    Emergency power operation
    This version of the hybrid inverter is only intended for use in grid connected photovoltaic systems. A device update is required from the manufacturer in order to generate power independently of the public grid. As well as providing functional enhancements for the hardware and software, this update also includes relevant user documentation.
    The hybrid inverter is delivered ready for supplying emergency power.

    Power outage
    The standard measurement and safety procedures integrated into the inverter ensure that in the event of a power outage, the feed-in of energy is immediately interrupted (e.g. switch-off by the energy supplier or damage to lines).
