Danger from crushing due to the incorrect handling of attachments and connection parts.
Injuries to limbs may result.
When lifting up, putting down and attaching the inverter, use the integrated grips.
When fitting attachments, ensure that no limbs are located between the attachment and the inverter.
Do not hold onto the individual poles on the terminals when locking and unlocking.
In addition to the Operating Instructions, all applicable local rules and regulations regarding accident prevention and environmental protection must also be followed.
All safety and danger notices on the device:Any safety devices that are not fully functional must be repaired by an authorized specialist before the device is switched on.
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.
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.
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.
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.
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.
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:
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:
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.
The user is responsible for the safekeeping of any changes made to the factory settings. The manufacturer accepts no liability for any deleted personal settings.

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).

Ambient air is drawn in by the fan on the front side and blown out at the device sides. The even heat dissipation allows several inverters to be installed next to each other.
Risk due to insufficient cooling of the inverter.
This may result in a loss of power in the inverter.
Do not block the fan (for example, with objects that protrude through the touch guard).
Do not cover the ventilation slots, even partially.
Make sure that the ambient air can always flow through the inverter's ventilation slots unimpeded.

In order to be able to obtain the highest rate of self-consumption with your PV system, a battery can be used to store excess energy. The battery is coupled to the inverter on the direct current side. Multiple current conversion is therefore not required, and the efficiency is increased.
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.
In the case of hybrid inverters, there are four different energy flow directions:
(1) | PV module – inverter – load/grid |
(2) | PV module – inverter – battery* |
(3) | Battery – inverter – load/grid* |
(4) | Grid – inverter – battery* |
* depending on the settings and local standards and regulations.
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.
Operating state | Description |
---|---|
Normal operation | Energy is stored or drawn, as required. |
Min. state of charge (SOC) achieved | Battery has reached the minimum SOC set or specified by the manufacturer. The battery cannot be discharged any further. |
Energy saving mode (standby) | The system has been put into energy saving mode. Energy saving mode is automatically ended as soon as sufficient excess energy is available again. |
Start | The storage system starts from energy saving mode (standby). |
Forced re-charging | The inverter re-charges the battery, in order to maintain the set minimum SOC (state of charge) or the SOC specified by the manufacturer (protection against deep discharge). |
Deactivated | The battery is not active. It has either been deactivated/switched off, or an error means that no communication with the battery is possible. |
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.
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.
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.
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.
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.

There is no energy available from the PV modules or from the public grid. If backup power operation or battery operation are not possible (e.g. deep discharge protection of the battery), the inverter and battery switch off.
There is no energy available from the PV modules or from the public grid. If backup power operation or battery operation are not possible (e.g. deep discharge protection of the battery), the inverter and battery switch off.
Status codes about the inactive state of the battery are displayed on the user interface of the inverter or sent via Solar.web by means of SMS or e-mail (only if notification via Solar.web is configured accordingly).
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 (→).
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.
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)".
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)".
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 (→).
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.
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.
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.
Danger due to incorrect or unprofessional DC installation.
The result is risk of damage and in turn, risk of fire to the PV system due to inadmissible thermal loads that arise with an arc.
Check plug connections are in good condition.
Repair incorrect insulation as appropriate.
Complete connections as per the specifications.
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."
If one of the following safety devices is triggered, the inverter switches to a safe state:
In the safe state, the inverter no longer feeds energy in and is disconnected from the grid by opening the AC relays.
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.

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.
Risk of polarity reversal at the terminals due to improper connection of external power supplies.
This may result in severe damage to the inverter.
Check the polarity of the external power supply with a suitable measuring device before connecting it.
Connect the cables to the V+/GND outputs with the correct polarity.
IMPORTANT!
If the total output (6 W) is exceeded, the inverter switches off the entire external power supply.
(1) | Power limitation |
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.

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
230 V *13 A = max. 3 kW

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 (→).
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.
For further information and the Installation Instructions, see PV Point Comfort on page (→).

"Enforce Standby"
When the function is activated, the feed-in mode of the inverter is interrupted. This enables a powerless shutdown of the inverter and protects its components. When the inverter is restarted, the standby function is automatically deactivated.
"PV 1" and "PV 2"
Parameter | Value range | Description |
---|---|---|
"Mode" | Off | The MPP tracker is deactivated. |
Auto | The inverter uses the voltage at which the max. possible power of the MPP tracker is possible. | |
Fix | The MPP tracker uses the voltage defined in the "UDC fix". | |
"UDC fix" | 80 ‑ 530 V | The inverter uses the fixed preset voltage used at the MPP tracker. |
"Dynamic Peak Manager" | Off | The function is deactivated. |
On | The entire solar module string is checked for optimisation potential and determines the best possible voltage for feed-in mode. |
"Ripple Control"
Ripple control signals are signals sent out by the energy company to switch controllable loads on and off. Depending on the installation situation, ripple control signals may be attenuated or amplified by the inverter. The settings below can be used to counteract this if necessary.
Parameter | Value range | Description |
---|---|---|
"Reduction of Influence" | Off | The function is deactivated. |
On | The function is activated. | |
"Frequency of Ripple Control Signal" | 100 ‑ 3000 Hz | The frequency specified by the energy company must be entered here. |
"Grid Inductance" | 0.00001 ‑ 0.005 H | The value measured at the feed-in point must be entered here. |
"Measures against RCD/RCMU false triggers"
(when using a 30 mA residual current circuit breaker)
The national regulations of the grid operator or other factors may require a residual current circuit breaker in the AC connection lead.
For this situation, a type A residual-current circuit breaker is generally adequate. Nevertheless, false alarms can be triggered for the type A residual-current circuit breaker in individual cases and depending on local conditions. For this reason, in accordance with national legislation, Fronius recommends that a residual-current circuit breaker with a tripping current of at least 100 mA suitable for frequency converters be used.
Parameter | Value range | Description |
---|---|---|
"Switch-Off before 30mA RCD Trip" | 0 | No measures to prevent false tripping. |
1 | The inverter switches off at 15 mA before the residual-current circuit breaker trips. | |
"Leakage current factor to reduce RCMU/RCD false trips" (only for Symo GEN24) | 0 ‑ 0.25 | Reducing the setting value reduces the leakage current and raises the intermediate circuit voltage, which slightly reduces the efficiency. Setting value 0.16 enables optimum efficiency. |
"Iso Warning"
Parameter | Value range | Description |
---|---|---|
"Iso Warning" | Off | The isolation warning is deactivated. |
On | The isolation warning is activated. | |
"Iso Alternative Mode"
| Accurate | Isolation monitoring is performed with the highest accuracy and the measured insulation resistance is displayed on the user interface of the inverter. |
Fast | Isolation monitoring is performed with lower accuracy, which shortens the duration of the isolation measurement, and the isolation value is not displayed on the user interface of the inverter. | |
"Isolation Warning Threshold" | 100,000 ‑ | If this threshold is undershot, status code 1083 is displayed on the user interface of the inverter. |
"Backup Power"
Parameter | Value range | Description |
---|---|---|
"Backup Nominal Voltage" | 220 ‑ 240 V | Is the nominal phase voltage output in backup power mode. |
"Backup Undervoltage Protection Limit U< [pu]" | 0 ‑ 2 %V | The setting value is used to set the limit value for switching off backup power mode, |
"Backup Undervoltage Protection Time U<" | 0.04 ‑ 20 s | Triggering time for falling below the backup power undervoltage protection limit value. |
"Backup Overvoltage Protection Limit U> [pu]" | 0 ‑ 2 %V | The setting value is used to set the limit value for switching off backup power mode, |
"Backup Overvoltage Protection Time U>" | 0.04 ‑ 20 s | Triggering time for exceeding the backup power overvoltage protection limit value. |
"Backup Restart Delay" | 0 ‑ 600 s | Is the waiting time for resumption of backup power mode after a shutdown. |
"Backup Restart Attempts" | 1 ‑ 10 | Is the max. number of automatic restart attempts. When the max. number of automatic restart attempts is reached, the service message 1177 must be acknowledged manually. |
"Backup External Frequency Check"
| Off | The function is deactivated |
On | For backup power mode (Full Backup) in Italy, the external frequency check must be activated. Before ending backup power mode, the grid frequency is checked. When the grid frequency is in the allowed limit range, the loads are connected to the public grid. | |
"Backup Short Circuit Trip Time" | 0.001 ‑ 60 s | If a short circuit occurs in backup power mode, this mode is interrupted within the set time. |
New rules for charging batteries will apply in Germany from 1 January 2024. The maximum charging power from public grids is 4.2 kW when controlled in accordance with Section 14a of the EnWG (Law on the Fuel and Electricity Industries).
The inverter must establish a connection to Solar.web for documentation purposes and be permanently connected to the internet in order to be able to prove the implementation of the external control commands.
The charging power is limited to a value below this by default. Make sure not to use more than the allowed 4.2 kW charging power.

The charging power is limited to a value below this by default. Make sure not to use more than the allowed 4.2 kW charging power.
"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).
"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.
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.
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".
The examples below serve to explain the energy flows. Efficiency levels are not taken into account.
Example: Battery system | |
---|---|
PV system available power | 1000 W |
Power into the battery | 500 W |
Power output (AC) of the inverter | 500 W |
Target value set at feed-in point | 0 W |
Infeed into the public grid | 0 W |
Consumption in home | 500 W |
Example: Battery system without photovoltaics, including second producer in the house | |
---|---|
Power into the battery | 1500 W |
Power consumption (AC) of the inverter | 1500 W |
Second producer in home network | 2000 W |
Target value set at feed-in point | 0 W |
Infeed into the public grid | 0 W |
Consumption in home | 500 W |
Example: Battery system including second producer in the house | |
---|---|
PV system available power | 1000 W |
Power into the battery | 2500 W |
Power consumption (AC) of the inverter | 1500 W |
Second producer in home network | 2000 W |
Target value set at feed-in point | 0 W |
Infeed into the public grid | 0 W |
Consumption in home | 500 W |
Example: Battery system including second producer in the house (with AC max. limitation) | |
---|---|
PV system available power | 1000 W |
Power into the battery | 2000 W |
Power consumption AC max. limited to | 1000 W |
Power consumption (AC) of the inverter | 1000 W |
Second producer in home network | 2000 W |
Target value set at feed-in point | 0 W |
Infeed into the public grid | 500 W |
Consumption in home | 500 W |
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
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.
Example | |
---|---|
Fronius inverter (max. output power) | 6000 W |
Defined battery discharging | 6000 W |
PV power | 1000 W |
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.
"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.

Energy companies or grid operators may stipulate export limitations for an inverter (e.g. max. 70% of kWp or max. 5 kW).
The export limitation takes account of self-consumption by the household before the power of an inverter is reduced:
With the inverter, any PV power that is not allowed to be fed into the public grid is used to charge the battery instead and/or used by the Fronius Ohmpilot so that it does not go to waste. The feed-in limitation is only active if the power of feeding in is higher than the set power reduction.
"Power limitation" deactivated
The inverter converts the entire available PV power and feeds it into the public grid.
"Power limitation" activated
Feed-in is limited with the following selection options:
Example: "Limit per Phase" (setting value: 1,000 W) | ||||
---|---|---|---|---|
| Phase 1 | Phase 2 | Phase 3 | Total |
Max. possible production [Wp] | 1,000 | 1,000 | 1,000 | 3,000 |
Set value | 500 | 1,500 | ||
Load demand in the household network [W] | 500 | 750 | 1,250 | 2,500 |
Load coverage in the household network via PV system [W] | 500 | 1,500 | ||
Purchase from the public grid [W] | 0 | 250 | 750 | 1,000 |
"Total DC power of the Entire System"
Input field for the total DC system power in Wp.
If there are multiple Fronius inverters, this value is used when the "Maximum Grid Feed-In Power" is specified in %.
"Soft Limit"
If this value is exceeded, the inverter will regulate down to the set value within the time required by national standards and regulations.
"Hard Limit"
If this value is exceeded, the inverter switches off within max. 5 seconds. This value must be higher than the value set for "Soft Limit".
"Maximum Grid Feed-In Power"
Input field for the "Maximum Grid Feed-In Power" in W or % (setting range: -10 to 100%).
If there is no meter in the system, the inverter limits the power of feeding in to the set value. Activate the function "Reduce inverter power to 0% if meter connection has been lost." for control in the event of a Fail-Safe.
Example: Export limitation | |
---|---|
PV system to Fronius inverter | 5,000 W |
Loads in the house | 1,000 W |
Maximum grid feed-in power | 60% = 3,000 W |
| |
Case 1: The battery can be charged | |
Power at grid feed-in point | 0 W |
Power at inverter output | 1,000 W |
Power into the battery | 4,000 W |
| |
Case 2: The battery cannot be charged | |
Power at grid feed-in point | 3,000 W |
Power at inverter output | 4,000 W |
Power into the battery | 0 W |
In this example, no more than 3,000 W may be fed into the public 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. |

The inverter is designed in such a way that no additional maintenance work builds up. Nevertheless, a few points must be considered during operation to ensure that the inverter works perfectly.
Maintenance and servicing may only be carried out by Fronius-trained service technicians.
Clean the inverter as required with a damp cloth.
Do not use cleaning agents, abrasives solvents or similar to clean the inverter.
The DC disconnector is used only to switch off power to the power stage set. When the DC disconnector is turned off, the connection area is still energized.
Danger from grid voltage and DC voltage from PV modules.
This can result in serious injury and damage to property.
The connection area must only be opened by an authorised electrician.
The separate power stage set area must only be opened by Fronius-trained service technicians.
Prior to any connection work, disconnect the inverter on the AC side and the DC side.
Danger of residual voltage from capacitors.
This can result in serious injury and damage to property.
Allow the capacitors of the inverter to discharge (2 minutes).
If the inverter is operated in dusty environments, dirt may build up on the heat sink and fan.
This may result in a loss of power due to insufficient cooling of the inverter.
Make sure that the ambient air can always flow through the inverter's ventilation slots unimpeded.
Remove any build-up of dirt on the heat sink and the fan.
Switch off power to the inverter and wait for the specified time (2 minutes) until the capacitors have discharged and the fan has shut down.
Turn the DC disconnector to the "Off" position.
Loosen the screws on the underside of the housing cover by rotating them 180° to the left using a screwdriver (TX20). Then lift the housing cover away from the inverter at the bottom and detach from above.
Remove any build-up of dirt on the heat sink and fan using compressed air, or a cloth or brush.
Risk due to damage to the fan bearing from improper cleaning.
Excessive speed and pressure on the fan bearing can cause damage.
Block the fan and clean it with compressed air.
When using a cloth or brush, clean the fan without applying pressure to the fan.
To start up the inverter again, follow the steps listed above in reverse order.
Waste electrical and electronic equipment must be collected separately and recycled in an environmentally responsible manner in accordance with the EU Directive and national law. Used equipment must be returned to the distributor or through a local, authorised collection and disposal system. Proper disposal of the old device promotes sustainable recycling of material resources. Ignoring this may lead to potential health/environmental impacts.
