1. Safety rules

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

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

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

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.

1. General information
2. Emergency 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!

1. General information
2. Emergency power mode

• 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.

• Enough energy is available from the PV modules.
• The public grid is functioning again.
• The battery's POWER switch is switched off and on.

More information on energy saving mode can be found in chapter Energy saving mode on page (→)

2. Energy saving mode

		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.

1. General information
2. Energy saving mode

• 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.

1. General information
2. Energy saving mode

If the inverter does not operate for 8–12 minutes (e.g.: error), or if there is an interruption in the electrical connection between the inverter and battery, the battery switches into energy saving mode in any case. This reduces self discharge of the battery.

Energy saving mode is shown on the website of the inverter and in Solar.web by an "i" beside the battery symbol in the system overview.

1. General information

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.

• 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

• 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 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

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

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

• 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

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.

Status codes (state codes), the status of the inverter (e.g. feeding energy into the grid) or Energy Manager functions can be displayed using the floating switch contact (relay).

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

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

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.

Possible applications:

2. General

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.

1. Fronius system monitoring

When using Fronius system monitoring, data is collated that must be transmitted over the internet.
The data volume must be calculated so that the correct internet connection is selected.

The data volume calculation below provides an overview of the data quantities involved when using Fronius system monitoring.

2. Calculating data volumes

When using Fronius system monitoring, data is collated that must be transmitted over the internet.
The data volume must be calculated so that the correct internet connection is selected.

The data volume calculation below provides an overview of the data quantities involved when using Fronius system monitoring.

1. Fronius system monitoring
2. Calculating data volumes

The data volume calculation depends on the number of connected devices in the system monitoring.
The table below provides an overview of the data volume for various configurations and time settings (INV = Fronius Symo Hybrid, SM = Smart Meter, BAT = battery module of the Fronius Solar Battery)

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.

1. Fronius system monitoring

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.

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

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.

2. Installing Fronius system monitoring – Overview

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.

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)

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

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

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

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".

• "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".

Demand Response Modes for Australia

The pins for control via DRM can be set here:

IMPORTANT! To control the inverter via DRM, a Fronius DRM interface (item number 4,240,005) is required in the inverter. Installation is described in the Installation Instructions for the Fronius DRM interface. The Installation Instructions for the Fronius DRM interface are available on the Fronius homepage at the following link:
	http://www.fronius.com/QR-link/4204102292

The remote control capability of the inverter always relates to the nominal device output.

IMPORTANT! If no DRM control (DRED) is connected to the Datamanager and the "AUS - Demand Response Mode (DRM)" function is activated, the inverter switches to standby mode.

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 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.

• 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.

• 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).

• Field for activating a desired running time

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 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.

Own consumption optimization
Option for selecting automatic or manual self-consumption optimisation

Target value at the metering point
If you opt for "manual" under "Own consumption optimization", you can select the target value at the metering point and choose between "Consumption" and "Feed-in" here

Backup power

  Operating mode
"Automatic" or "Off" can be selected for backup power mode.
The backup power functionality can only be activated once the required IO assignments have been configured for backup power. The meter must be installed at the feed-in point and configured.

Residual battery capacity
Energy is drawn from the battery in grid-connected operation until this residual battery capacity is reached. In backup power mode without a grid, the battery is always discharged to the minimum SOC preset by the battery manufacturer.

SOC warning level
A warning is output when the residual capacity of the battery specified here is reached in backup power mode.
