Never bypass or disable protection devices.

For the location of the safety and danger notices on the device, refer to the chapter headed "Warning notices on the device" in the Operating Instructions for your device.

Faults that could compromise safety must be remedied before switching on the device.

1. Safety rules

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

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 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 grid 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 has backup power functions, which enable a replacement power supply to be established in the event of a failure of the public grid.

Where an automatic backup power supply is installed, a backup power warning notice (https://www.fronius.com/en/search-page, item number: 42,0409,0275) must be fitted on the electrical distributor.

Maintenance and installation work in the home network requires both disconnection on the utility side and deactivation of the replacement power mode by opening the integrated DC disconnector on the inverter.

The function of the residual current devices for the backup power supply must be checked at regular intervals (according to the manufacturer's instructions), but at least twice a year.
A description on how to perform the test operation can be found in the backup power checklist (https://www.fronius.com/en/search-page, item number: 42,0426,0365).

Depending on the insolation conditions and the battery state of charge, the backup power supply is automatically deactivated and activated. This can cause the backup power supply to unexpectedly return from standby mode. Therefore, installation work can only be performed on the home network when the backup power supply is deactivated.

Influencing factors on the total power in backup power mode:

Reactive power
Electrical loads with a power factor not equal to 1 also require reactive power in addition to effective power. The reactive power also loads the inverter. Therefore, to correctly calculate the actual total power, it is not the rated power of the load that is relevant, but the current caused by effective and reactive power.

Devices with a high reactive power are mainly electric motors such as:

• Water pumps
• Circular saws
• Blowers and fans

High starting current
Electrical loads that need to accelerate a large mass usually require a high starting current. This can be up to 10 times higher than the nominal current. The maximum current of the inverter is available for the starting current. Loads with too high starting currents therefore cannot be started/operated, even though the nominal power of the inverter suggests that they can. When dimensioning the backup power circuit, the connected load power and any starting current must also be taken into account.

Devices with high starting currents are, for example:

• Devices with electric motors (e.g. lifting platform, circular saws, planing bench)
• Devices with large transmission ratio and flywheel mass
• Devices with compressors (e.g. compressed air compressors, air conditioning systems)

IMPORTANT!
Very high starting currents can cause short-term distortion or a drop in output voltage. The simultaneous operation of electronic devices in the same backup power supply system should be avoided.

Load imbalance
When dimensioning three-phase backup power networks, the total output power and the power output per phase of the inverter must be taken into account.

IMPORTANT!
The inverter may only be operated within the limits of its technical capabilities. Operation outside of its technical capabilities can cause the inverter to shut down.

Copyright of these operating instructions remains with the manufacturer.

The text and illustrations are all technically correct at the time of printing. We reserve the right to make changes. The contents of the operating instructions shall not provide the basis for any claims whatsoever on the part of the purchaser. If you have any suggestions for improvement, or can point out any mistakes that you have found in the instructions, we will be most grateful for your comments.

1. Safety rules

Connection of a point in the device, system or installation to earth to protect against electric shock in the event of a fault. When installing a safety class 1 inverter (see Technical data), the ground conductor connection is required.

When connecting the ground conductor, ensure that it is secured against accidental disconnection. All the points listed in Connecting the inverter to the public grid (AC side) on page (→) must be observed. When using cable glands, ensure that the ground conductor will be strained last in the event of failure of the cable gland. When connecting the ground conductor, the minimum cross-section requirements specified by the respective national standards and guidelines must be observed.

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

The inverter is intended for use in grid-connected photovoltaic systems. The inverter has a backup power function and switches to backup power mode if it has been wired accordingly*.

The inverter automatically monitors the public grid. Whenever conditions in the electric grid are inconsistent with standard conditions (for example, grid switch-off, interruption), the inverter will immediately stop producing power and interrupt the supply of power into the grid.
The grid is monitored by monitoring the voltage, frequency and islanding conditions.

After installation and commissioning, the inverter's operation is fully automatic; the inverter draws the maximum possible power from the PV modules.
Depending on the operating point, this power is used in the home, stored in a battery* or fed into the grid.

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*.

When its temperature gets too high, the inverter automatically reduces the output or charging power, or switches off completely, in order to protect itself.
Reasons for the temperature being too high include a high ambient temperature or insufficient heat dissipation (for example, inadequate heat dissipation when installed in switch cabinets).

In the hybrid photovoltaic system, batteries must only be connected to one inverter with battery support. Batteries cannot be split between multiple inverters with battery support. However, depending on the battery manufacturer, several batteries can be combined on one inverter.

1. General information
2. The various operating modes

In the case of hybrid inverters, there are four different energy flow directions:

* depending on the settings and local standards and regulations.

1. General information
2. The various operating modes

Battery systems distinguish different operating states. In this case, the relevant current operating state is displayed on the user interface of the inverter or in Solar.web.

1. General information

Energy saving mode (standby mode) is used to reduce the self-consumption of the system. Both the inverter and the battery automatically switch to energy saving mode under certain conditions.

The inverter switches to energy saving mode if the battery is flat and no PV power is available. Only the inverter's communication with the Fronius Smart Meter and Fronius Solar.web is maintained.

2. Energy saving mode

Energy saving mode (standby mode) is used to reduce the self-consumption of the system. Both the inverter and the battery automatically switch to energy saving mode under certain conditions.

The inverter switches to energy saving mode if the battery is flat and no PV power is available. Only the inverter's communication with the Fronius Smart Meter and Fronius Solar.web is maintained.

1. General information
2. Energy saving mode

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

		The battery state of charge is less than or equal to the input minimum state of charge.
		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 into the public grid is at least 50 W less than the power currently required in the home network.

The inverter automatically switches into energy saving mode, following the battery.

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.
• If dynamic power reduction of 0 is set, or if the system is operating in backup power mode, the power of feeding into 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, energy saving mode is ended.
• Battery charging from the public grid is requested via the user interface of the inverter.
• The battery is being recharged in order to restore the minimum state of charge or perform calibration.

1. General information
2. Energy saving mode

If the inverter does not operate for 12 minutes (e.g. fault), or there is an interruption in the electrical connection between the inverter and the battery and there is no backup power mode, the battery switches to energy-saving mode in any case. This reduces self discharge of the battery.

1. General information
2. Energy saving mode

• Operating LED for the inverter lights up orange (see Button functions and LED status indicator on page (→)).
• The user interface of the inverter can be reached.
• All the available data is saved and transmitted to Solar.web.
• The real-time data can be seen on Solar.web.

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

1. General information
2. Manual system start

As soon as energy is available again, the inverter starts operation automatically; however the battery must be started manually. The switch-on sequence must be observed for this, see chapter Suitable batteries on page (→).

1. General information
2. Manual system start

The inverter requires energy from the battery to start backup power operation. This is done manually on the battery; further information on the power supply for restarting the inverter via the battery can be found in the battery manufacturer's Operating Instructions.

1. General information

The inverter offers the option to use the integrated AC relays as coupling switches in conjunction with a central grid and system protection unit (in accordance with VDE-AR-N 4105:2018:11 §6.4.1). For this purpose, the central trigger device (switch) must be integrated into the WSD chain as described in the chapter "WSD (Wired Shut Down)".

1. General information
2. Protection of people and equipment

The inverter offers the option to use the integrated AC relays as coupling switches in conjunction with a central grid and system protection unit (in accordance with VDE-AR-N 4105:2018:11 §6.4.1). For this purpose, the central trigger device (switch) must be integrated into the WSD chain as described in the chapter "WSD (Wired Shut Down)".

1. General information
2. Protection of people and equipment

The wired shutdown (WSD) interrupts the inverter feeding energy into the grid if the trigger device (switch, e.g. emergency stop or fire alarm switch) has been activated.

If an inverter (secondary device) fails, it is bypassed and the other inverters continue operating. If a second inverter (secondary device) or the inverter (primary device) fails, the operation of the entire WSD chain is interrupted.

For installation, see Installing the WSD (wired shutdown) on page (→).

1. General information
2. Protection of people and equipment

The inverter is equipped with a universal current-sensitive residual current monitoring unit (RCMU = Residual Current Monitoring Unit) in accordance with IEC 62109-2 and IEC63112.
This device monitors residual currents from the PV module to the AC output of the inverter and disconnects the inverter from the grid in the event of unauthorised residual current.

1. General information
2. Protection of people and equipment

In the case of PV systems with ungrounded solar modules, the inverter checks the resistance between the positive or negative pole of the PV system and the ground potential before feeding energy into the grid. In the event of a short circuit between DC+ or DC- cable and ground (e.g. due to inadequately insulated DC cables or damaged solar modules), an infeed into the grid is prevented.

1. General information
2. Protection of people and equipment

AFCI (Arc Fault Circuit Interrupter) protects against arcing faults and in the narrower sense is a protection device against contact faults. The AFCI evaluates any DC-side faults that occur in the current and voltage curve with an electronic circuit and switches off the circuit when a contact fault is detected. This prevents overheating on poor contacts and ideally possible fires.

IMPORTANT!
Fronius will not accept any costs associated with production downtimes, installer costs, etc., that may arise as the result of a detected arc and its consequences. Fronius accepts no liability for damage that can occur despite the presence of the integrated Arc Fault Circuit Interrupter/extinguishing system ( e.g. caused by a parallel arc).

IMPORTANT!
Active PV module electronics (e.g., power optimiser) can impair the function of the Arc Fault Circuit Interrupter. Fronius does not guarantee that the Arc Fault Circuit Interrupter will work correctly in combination with active PV module electronics.

Reconnection behaviour
After detection of an arc, feeding energy into the grid is interrupted for at least 5 minutes. Depending on the configuration, feeding energy into the grid is then automatically resumed. If several arcs are detected within a period of 24 hours, feeding energy into the grid can also be permanently interrupted until a manual reconnection has taken place."

1. General information
2. Protection of people and equipment

If one of the following safety devices is triggered, the inverter switches to a safe state:

• WSD
• Isolation monitoring
• RCMU

In the safe state, the inverter no longer feeds energy in and is disconnected from the grid by opening the AC relays.

1. General information
2. Protection of people and equipment

The inverter is equipped with an integrated surge protective device on the DC and AC side in accordance with IEC 62109-2. The surge protective device protects the system against damage in the event of a surge.

1. General information
2. Control elements and connections

On the V+/GND pin, it is possible to feed in a voltage of around 12.5–24 V (+ max. 20%) with an external power supply. The outputs IO 0–5 can then be operated with the external voltage. A maximum of 1 A can be drawn per output, with a maximum of 3 A allowed in total. The fuse protection must be located externally.

IMPORTANT!
If the total output (6 W) is exceeded, the inverter switches off the entire external power supply.

IMPORTANT!
If several backup power variants are available, please note that only one backup power variant may be installed and configured.

The inverter can provide 220 ‑ 240 V at the PV Point/PV Point Comfort. A corresponding configuration must be set up during commissioning.

At 220 ‑ 240 V output voltage, max. 13 A AC continuous current is available.

Example:
220 V *13 A = 2860 W
230 V *13 A = max. 3 kW

In backup power mode, some electrical appliances cannot function properly as starting currents are too high (for example, fridges and freezers). It is recommended to switch off non-essential loads during backup power mode. Overload capacity of 35 % is possible for a duration of 5 seconds, depending on the capacity of the PV modules and/or the battery at that moment in time.

There is a brief interruption when switching from grid-connected mode to backup power mode. For this reason, the backup power function cannot be used as an uninterruptible power supply, for example for computers.

If no energy from the battery or the PV modules is available in backup power mode, backup power mode ends automatically. If sufficient energy becomes available from the PV modules once again, backup power mode starts again automatically.

In the event of excessive consumption, backup power mode is stopped and the "backup power overload" status code is displayed on the inverter's LED status indicator (see Button functions and LED status indicator on page (→)). The maximum power in backup power mode according to the technical data must be observed.

IMPORTANT!
If several backup power variants are available, please note that only one backup power variant may be installed and configured.

The inverter can provide 220 ‑ 240 V at the PV Point/PV Point Comfort. A corresponding configuration must be set up during commissioning.

At 220 ‑ 240 V output voltage, max. 13 A AC continuous current is available.

Example:
220 V *13 A = 2860 W

2. General

With the PV Point, in the event of a failure of the public grid, 1‑phase electrical devices can be connected to the Opportunity Power (OP) terminal and supplied with a maximum power of 3 kW, if enough power is available from the PV modules or an optional battery. In grid-connected operation, the OP terminal is not supplied with voltage, therefore the connected loads will not be continuously supplied with power.

IMPORTANT!
A relay-based network switching setup is not possible.

Installation Instructions, see Connecting backup power - PV Point (OP) on page (→).

1. Backup power variant - PV Point (OP)
2. General

With PV Point Comfort, 1-phase electrical devices are continuously supplied up to a maximum power of 3 kW.
Switching between grid-connected and backup power mode takes place automatically. In the event of a failure of the public grid or the inverter, the loads on the PV Point Comfort continue to be supplied. When the public grid is available again and stability is assured, the PV Point Comfort automatically switches to grid-connected operation and backup power mode is terminated.

IMPORTANT!
There must be sufficient power from the PV modules or a battery for backup power mode to run.

2. General

All installed components in the photovoltaic system must be compatible and have the necessary configuration options. The installed components must not restrict or negatively influence the functioning of the photovoltaic system.

1. Installation

Please note the following criteria when choosing a location for the inverter:

		Only install on a solid, non-flammable surface.
		Max. ambient temperatures: -25 °C – +60 °C
		Relative humidity: 0-100%
		If the inverter is installed in a switch cabinet or similar enclosed space, ensure sufficient heat dissipation with forced-air ventilation. For detailed information on the dimensions of the inverter, see chapter Fronius Symo GEN24 3-5 kW on page (→).
When installing the inverter on the outer walls of cattle sheds, it is important to maintain a minimum clearance of 2 m between the inverter and the ventilation and building openings on all sides.
The following substrates are permissible for installation: Walls (corrugated metal walls [mounting rails], brick walls, concrete walls, or other non-flammable surfaces sufficiently capable of bearing loads) Mast or support (installed using mounting rails, behind the PV modules directly on the PV mounting system) Flat roofs (if installing on a film roof, make sure that the films comply with the fire protection requirements and are not highly flammable. Ensure compliance with the national provisions.) Covered car park roofs (no overhead installation)

		The inverter is suitable for indoor installation.
		The inverter is suitable for outdoor installation. Due to its protection class IP 66, the inverter is insensitive to water jets from all directions and can also be used in humid environments.
		In order to minimise the heating up of the inverter, do not expose it to direct insolation.
		The inverter should be installed in a protected location, for example, below the PV modules or under an overhanging roof.
		The inverter must not be installed or used at altitudes above 4000 m.
		Do not install the inverter in: Areas where it may be exposed to ammonia, corrosive gases, acids or salts (e.g. fertiliser storage areas, vent openings for livestock stables, chemical plants, tanneries, etc.)
		During certain operating phases the inverter may produce a slight noise. For this reason it should not be installed in an occupied living area.
		Do not install the inverter in: Areas where there is an increased risk of accidents from farm animals (horses, cattle, sheep, pigs, etc.) Stables or adjoining areas Storage areas for hay, straw, chaff, animal feed, fertilizers, etc.
		The inverter is designed to be dustproof (IP 66). In areas of high dust accumulation, dust deposits may collect on the cooling surfaces, and thus impair the thermal performance. Regular cleaning is required in this case, see chapter Operation in dusty environments on page (→). We therefore recommend not installing the device in areas and environments with high dust accumulation.
		Do not install the inverter in: Greenhouses Storage or processing areas for fruit, vegetables or viticulture products Areas used in the preparation of grain, green fodder or animal feeds

"Self-Consumption Optimization"
Set the operating mode to "Manual" or "Automatic". The inverter always regulates to the set "Target Value at Feed-In 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 and configured at the feed-in point.
• The "Allow battery charging from additional producers in home network" function must be activated in the "Components" → "Battery" menu area.

"Target Value at Feed-In Point"
If "Manual" has been selected under Self-Consumption Optimization, the "Operating Mode" ("Consumption"/"Feed-In") and the "Target Value at Feed-In Point" can be set.

IMPORTANT!
"Self-Consumption Optimization" has lower priority than "Battery Management".

External producers (only possible with active battery)
If further decentralised producers are installed in the house, and these are incorporated into the self-consumption control of the Fronius Hybrid inverter, the setting "Allow battery charging from additional producers in home network" must be activated in the menu area "Device Configuration" → "Components" (see Components on page (→)
.This means that energy can be drawn from the home network and fed into the battery via the Fronius inverter (battery support required). You can restrict how much power is consumed by the Fronius inverter by specifying the maximum AC power (AC max.). A maximum power consumption of the AC rated power of the Fronius inverter is possible.

"Battery Management"
Using the time-dependent battery control, it is possible to prevent or restrict charging/discharging of the battery and to specify a defined charging power.

• Permitted battery charging from the public grid
• Power limitation of the inverter, energy storage device or overall system
• Control specifications via Modbus
• Self-consumption optimization

IMPORTANT!
The defined rules for battery control have the second lowest priority after Self-Consumption Optimization. Depending on the configuration, the rules may not be satisfied due to other settings.

• "Max. charging power"
  The battery is charged to the maximum level with the value set in the "Power" input field.
  If no feed-in to the public grid and/or direct consumption in the house is possible, the set "Max. charging power" value is ignored and the energy generated is charged into the battery.
• "Min charging power"
  The battery is charged as a minimum by the value set in the input field "Power".
• "Max discharge power"
  The battery is discharged at most by the value set in the input field "Power".
• "Min discharge power"
  The battery is discharged as a minimum by the value set in the input field "Power".

The timing for when the rule applies is set in the "Time" input fields and by selecting the relevant "Weekdays".

It is not possible to define a time window over midnight (00:00).
Example: To set a control from 22:00 to 06:00, two inputs are required: "22:00 - 23:59" and "00:00 - 06:00".

2. Energy management

A rule always consists of a restriction or parameter and the time control "Time" and "Weekdays" while the rule is active. Rules with the same restriction (e.g. max. charging power) must not overlap in time.

Max. charging and discharging limits
The max. charging/max. discharging power can be configured at the same time.

Specifying the charging range
It is possible to define a charging range with a min. and max. charging limit. In this case, it is not possible for the battery to discharge.

Specifying the discharging range
It is possible to define a discharging range with a min. and max. discharging limit. In this case, it is not possible for the battery to charge.

Specifying a defined charging power
A defined charging power can be specified by setting the min. and max. charging power to the same value.

Specifying a defined discharging power
A defined discharging power can be specified by setting the min. and max. discharging power to the same value.

Possible applications

• Time-dependent electricity tariffs
• Battery reservation for market-specific power limitation
• Time-dependent storage reservation for a backup power situation

1. Settings - user interface of the inverter
2. Energy management

The rules in the "Battery Management" menu area enable optimum use of the energy generated. Situations may arise, however, in which PV power cannot be used in full due to the time-dependent battery control.

In this case, the inverter would have to reduce the PV power to 0 W, since the output power of the inverter is max. 6000 W and this is already being used to capacity by the battery discharging.

Since it doesn't make sense to waste PV power, the power limit is automatically adjusted in Battery Management such that no PV power is wasted. In the example above, this means that the battery is discharged only at 5000 W, so that the 1000 W PV power can be used.

2. Energy management

"Priorities"
If additional components (e.g. battery, Fronius Ohmpilot) are present in the system, the priorities can be set here. Devices having higher priority are actuated first, and subsequently, if there is still excess energy available, the other devices.

IMPORTANT!
If there is a Fronius Wattpilot in the photovoltaic system, it is seen as a load. The priority for the load management of the Wattpilot must be configured in the Fronius Solar.Wattpilot app.

"Rules"
It is possible for up to four different load management rules to be defined. At the same threshold values, the rules are activated in succession. For deactivation, this is done in reverse; the I/O last switched on is the first to be switched off. In the case of different thresholds, the I/O with the lowest threshold is switched on first, followed by the second lowest, and so on.

I/Os controlled by the produced power are always prioritised over a battery and Fronius Ohmpilot. That is to say that an I/O can switch on and result in the battery no longer being charged or the Fronius Ohmpilot no longer being activated.

IMPORTANT!
An I/O is activated/deactivated only after 60 seconds.

• Control is "Off" (disabled).
• Control is effected by the "Power Production".
• Control is effected by "Power Surplus" (given feed limits). This option can only be selected if a meter has been connected. Control is effected using the actual power of feeding in with respect to the grid.

• "On": For entering an effective power limit, at which the output is activated.
• "Off": For entering an effective power limit, at which the output is deactivated.

• Field for enabling "Minimum duration per on-signal", a minimum duration for which the output is to be activated for each switch-on process.
• Field for activating the "Maximum duration per day".
• Field for enabling a "Desired duration" for which the output is to be activated in total per day (total of several switch-on processes).
