Instructions for action
In addition to the operating instructions, all applicable local 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 safety devices.
For the location of the safety and danger notices on the device, refer to the chapter headed "Information on the device" in the operating instructions for your device.
Any equipment malfunctions which impair safety must be remedied before the device is turned on.
Operation or storage of the device outside the stipulated area will be deemed as not in accordance with the intended purpose.
The information contained in these operating instructions is intended only for qualified personnel. 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 must be secured, undamaged, insulated, and adequately dimensioned. Loose connections, damaged or under-dimensioned cables must be repaired immediately by an authorized specialist company.
Maintenance and repair work must only be carried out by an authorized specialist company.
It is impossible to guarantee that third-party parts are designed and manufactured to meet the demands made on them, or that they satisfy safety requirements. Only use original spare parts.
Do not carry out any alterations, installations, or modifications to the device without first obtaining the manufacturer's permission.
Replace any damaged components or have them replaced immediately.
The sound pressure level of the inverter is indicated in the Technical data.
The cooling of the device takes place via an electronic temperature control system at the lowest possible noise level and depends on the power used, ambient temperature, and the soiling level 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.
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, 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 starting currents that are too high therefore cannot be started/operated, even though the nominal output 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. Operating electronic devices simultaneously 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.

We are grateful for suggestions for improvement and information on any discrepancies in the operating instructions.
Connection of a point in the device, system, or installation to ground to protect against electric shock in the event of a fault. When installing an inverter from safety class 1 (see Technical data), a ground conductor connection is required.
When connecting the ground conductor, ensure that it is secured to prevent unintentional disconnection. All of the points listed in the chapter headed Connecting the inverter to the public grid (AC side) on page (→) must be observed. When using cable glands, ensure that the ground conductor is last to be subjected to a load in the event of a failure of the cable gland. The respective national standards and regulations and requirements for minimum cross-section must be observed when connecting the ground conductor.
The inverter transforms the direct current generated by the PV modules into alternating current. This alternating current is fed into the public grid and synchronized with the mains 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 backup power functions 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 (e.g., 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 solar 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 solar modules is no longer sufficient, the power from the battery is fed into the home network. 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).

* Sufficient PV and battery power required. Duration max. 5–10 seconds, 400 V AC symmetrical, depending on the environmental conditions.
Ambient air is drawn in by the fan on the top and bottom 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.
System owners and installers can easily monitor and analyze the PV system using Fronius Solar.web or Fronius Solar.web Premium. With the appropriate configuration, the inverter transmits data such as power, yield, load, and energy balance to Fronius Solar.web. More detailed information can be found at Solar.web - Monitoring & analysis.
Configuration is carried out using the Setup wizard; see the chapter headed Installation with the app on page (→) or Installation with the browser on page (→).
Requirements for configuration:| * | These specifications do not provide an absolute guarantee of flawless operation. High error rates in the transmission, fluctuating receptions or misfires can have an adverse effect on data transfer. Fronius recommends on-site testing to ensure that the connections meet the minimum requirements. |
The inverter can be found via the Multicast DNS (mDNS) protocol. We recommend searching for the inverter using the assigned host name.

In order to be able to obtain the highest rate of self-consumption with your photovoltaic 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.
IMPORTANT!
In backup power mode, an increased nominal frequency is used in order to prevent undesired parallel operation with other power generators.
IMPORTANT!
In the fully equipped hybrid PV system with a Fronius Ohmpilot, the Ohmpilot cannot be operated in the event of a power failure for regulatory reasons. It is therefore sensible to install the Ohmpilot outside of the backup power branch.
In the hybrid PV system, batteries may only be connected to an inverter with battery support. Batteries cannot be split between multiple inverters with battery support. Depending on the battery manufacturer, however, several batteries can be combined on one inverter.

Battery systems distinguish between different operating states. In each case, the relevant current operating state is displayed on the user interface of the inverter or in Fronius Solar.web.
Operating state | Description |
|---|---|
Normal operation | Energy is stored or drawn, as required. |
Min. state of charge (SoC) reached | The battery has reached the minimum SoC specified by the manufacturer or the set minimum SoC. The battery cannot be discharged 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 power is available again. |
Start | The storage system starts from energy-saving mode (standby). |
Forced re-charging | The inverter recharges the battery, in order to maintain the SoC specified by the manufacturer or the set SoC (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.

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.

Status codes about the inactive state of the battery are displayed on the user interface of the inverter. A notification via e-mail can be activated in Fronius Solar.web.
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.
Technical data, warning notices, labels, and safety symbols are located on and in the inverter.

The inverter offers the option to use the integrated AC relays as section 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 chapter WSD (wired shutdown) on page (→).
The wired shutdown (WSD) interrupts the inverter's grid power feed if the trigger device (switch, e.g., Emergency Stop or fire alarm contact) has been activated.
If an inverter (slave) fails, it is bypassed and the other inverters continue operating. If a second inverter (slave) or the inverter (master) 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 an RCMU (RCMU = residual current monitoring unit) according to IEC 62109-2 and IEC63112.
It monitors residual currents from the PV module up to the AC output and disconnects the inverter from the grid when an improper residual current is detected.
In the case of photovoltaic systems with ungrounded PV modules, the inverter checks the resistance between the positive or negative pole of the photovoltaic system and the ground potential before starting grid power feed operation. In the event of a short circuit between the DC+ or DC- cable and ground (e.g., due to inadequately insulated DC cables or defective PV modules), feeding into the public grid is prevented.
An AFCI (Arc Fault Circuit Interrupter) protects against arc faults and, in the narrower sense, is a protection device in the event of contact errors. The AFCI evaluates faults that occur in the current and voltage flow on the DC side using an electronic circuit and shuts down the circuit if a contact error is detected. This prevents overheating at poor contact points and, ideally, possible fires.
Danger from faulty or incorrect DC installation.
This may result in a risk of damage and, as a consequence, risk of fire in the PV system due to prohibited thermal loads that occur during an arc.
Check the plug connections to ensure that they are correct.
Repair faulty insulation correctly.
Perform connection work in line with the instructions.
IMPORTANT!
Fronius will not bear any costs that may arise due to a detected electric arc and its consequences. Fronius accepts no liability for damage which may occur despite the integrated Arc Fault Circuit Interrupter/interruption (e.g., due to a parallel arc).
IMPORTANT!
Active PV module electronics (e.g., power optimizers) can impair the function of the Arc Fault Circuit Interrupter. Fronius cannot guarantee the correct function of the Arc Fault Circuit Interrupter in combination with active PV module electronics.
Reconnection behavior
Grid power feed operation is interrupted for at least 5 minutes after an arc has been detected. Depending on the configuration, grid power feed operation is then automatically resumed. If several arcs are detected within a period of 24 hours, grid power feed operation can also be permanently interrupted until a manual reconnection has been performed.
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 the AC relay opening.
The inverter is designed to convert direct current from PV modules into alternating current and feed this power into the public grid. A backup power mode* is possible if the wiring is set up accordingly.
Intended use also means:Follow all grid operator regulations regarding energy fed into the grid and connection methods.
The inverter is a grid-connected inverter with backup power function and is not a stand-alone inverter. The following restrictions in backup power mode must therefore be observed:| * | Depending on the device variant, suitable battery, corresponding cabling, settings, and local standards and regulations. |

Primary meter
For problem-free operation with further energy generators and in Full Backup power mode, it is important to install the Fronius Smart Meter at the feed-in point. The inverter and further producers must be connected to the public grid via the Fronius Smart Meter.
This setting also has an effect on the behavior of the inverter during the night. If the function is deactivated, the inverter switches to standby mode as soon as there is no more PV power available and no energy management specification is sent to the battery (e.g., minimum state of charge reached). The message "Power low" is displayed. The inverter starts again as soon as an energy management specification is sent or sufficient PV power is available.
If the function is activated, the inverter remains permanently connected to the grid in order to draw energy from other producers at any time.
After connecting the meter, select one of the following device types:
For communication via MQTT, the inverter and Smart Meter must be in the same sub-network.
The following parameters must also be defined for the Smart Meter:
The Watt value for the production meter is the sum of all production meters. The Watt value for the consumption meter is the sum of all secondary meters.
Battery
If the SoC Limit Mode is set to Auto, the values SoC Minimum and SoC Maximum are preset according to the technical specifications of the battery manufacturer.
If the SoC Limit Mode is set to Manual, the values SoC Minimum and SoC Maximum can be changed after consultation with the battery manufacturer within the framework of their technical specifications. In a backup power situation, the set values are not taken into account.
The setting Allow battery charging from other generators in the home network activates/deactivates charging of the battery from other generators.
The power consumption of the Fronius inverter can be restricted by specifying a value in the Max. Charging Power from AC field. As a maximum, a power consumption equal to the AC rated power of the Fronius inverter is possible.
The setting Allow battery charging from public grid + Allow battery charging from other generators in the home network activates/deactivates the charging of the battery from the public grid and, if present, from other generators in the home network.
The normative or compensatory specifications must be taken into account for this setting. Irrespective of this setting, necessary service-related charging from the public grid is performed (e.g., forced re-charging to protect against deep discharge).

Backup Power
In backup power mode, it is possible to select between Off and Full Backup.
The backup power mode Full Backup can only be activated once the required I/O assignments for backup power have been configured. In addition, a meter must be installed and configured at the feed-in point for the backup power mode Full Backup.
IMPORTANT!
When configuring the "Full Backup" backup power mode, the instructions in chapter Safety on page (→) must be observed.
Backup Nominal Voltage
When backup power mode is activated, the nominal voltage of the public grid must be selected.
SoC warning level
In backup power mode, a warning is emitted when this residual battery capacity is reached.
Reserve Capacity
The set value results in a residual capacity (depending on the capacity of the battery) that is reserved for backup power situations. The battery is not discharged below the residual capacity in grid connected mode. In backup power mode, the manually set value of SoC Minimum is not taken into account. If there is a backup power situation, the battery is always discharged up to the automatically preset, minimum SoC according to the technical specifications of the battery manufacturer.
System preservation during night
To ensure continuous backup power operation even during the night, the inverter calculates a reserve for system preservation depending on the battery capacity. When the calculated limit value is reached, standby mode is activated for the inverter and the battery and maintained for a period of 16 hours. Connected loads are no longer supplied. The battery is discharged up to the preset minimum SoC.
Load Management
Up to four pins for the load management can be selected here. Further settings for the load management are available in the Load Management menu item.
Default: Pin 1
Australia - Demand Response Modes (DRM)
The pins for control via DRM can be set here:
Mode | Description | Information | DRM Pin | I/O Pin |

DRM8 | Export Pnom ≤ 100% | currently not supported | DRM 4/8 | IN9 |
The percentage specifications always relate to the rated device power. | ||||
IMPORTANT!
If the Demand Response Mode (DRM) function is activated and no DRM control is connected, the inverter switches into standby mode.
Here you can enter a value for the apparent power input and the apparent power output for the Australia country setup.
Force standby
When this function is activated, the supply of energy from the inverter into the grid is interrupted. This makes it possible to shut down the inverter without power and protect its components. The standby function is automatically deactivated when the inverter is restarted.
AC grid
Parameter | Value range | Description |
|---|---|---|
Neutral conductor status | Not connected | The neutral conductor is not required in the system configuration and therefore not connected. |
Connected | The neutral conductor is connected. |
PV 1 to PV 3
Parameter | Value range | Description |
|---|---|---|
Mode | Off | The MPP tracker is deactivated. |
Auto | The inverter uses the voltage at which the max. possible output of the MPP tracker is possible. | |
Fixed | The MPP tracker uses the voltage defined in UDC fixed. | |
UDC fixed | 150 ‑870 V | The inverter uses the fixed voltage that is used on the MPP tracker. |
Dynamic Peak Manager | Off | Function is deactivated. |
On | The entire solar module string is checked for optimization potential and determines the best possible voltage for the supply of energy from the inverter into the grid. |
Ripple control signal
Ripple control signals are signals that are sent by the energy company in order to switch controllable loads on and off. Depending on the installation situation, ripple control signals can be dampened or amplified by the inverter. This can be counteracted if necessary by applying the following settings.
Parameter | Value range | Description |
|---|---|---|
Reduction of influence | Off | Function is deactivated. |
On | Function is activated. | |
Frequency of ripple control signal | 100 ‑ 3 000 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 to prevent FI/RCMU false alarms
(when using a 30 mA residual current circuit breaker)
A residual current circuit breaker for the AC connecting cable may be required depending on national regulations, the grid operator, and other conditions.
A type A residual current circuit breaker is generally sufficient in this case. Nevertheless, false trips can be triggered for the type A residual current circuit breaker in individual cases and depending on local conditions. For this reason, Fronius recommends using a residual current circuit breaker suitable for frequency inverters with a release current of least 100 mA, taking into account national provisions.
Parameter | Value range | Description |
|---|---|---|
Leakage current factor for reducing RCMU/RCD false trips | 0 ‑ 0.25 | By reducing the set value, the leakage current is reduced, and the intermediate circuit voltage is increased, which slightly lowers the efficiency.
|
Switch-off before 30 mA RCD trip | Off | The function for reducing the faulty tripping of the residual current circuit breaker is deactivated. |
On | The function for reducing the faulty tripping of the residual current circuit breaker is activated. | |
Rated residual non-operating current limit value | 0.015 ‑ 0.3 | Value of the non-trigger fault current determined by the manufacturer for the residual current circuit breaker, at which the residual current circuit breaker does not switch off under specified conditions. |
Insulation warning
Parameter | Value range | Description |
|---|---|---|
Insulation warning | Off | The insulation warning is deactivated. |
On | The insulation warning is activated. | |
Insulation alternative mode
| Accurate | Insulation monitoring takes place with the highest degree of accuracy and the measured insulation resistance is displayed on the user interface of the inverter. |
Fast | Insulation monitoring takes place with a lesser degree of accuracy, whereby the time to take the insulation measurement is shortened and the insulation value is not displayed on the user interface of the inverter. | |
Insulation warning threshold | 100 ‑ | If the value drops below the threshold, status code 1083 is displayed on the user interface of the inverter. |
Backup power
Parameter | Value range | Description |
|---|---|---|
Backup power nominal voltage | 220 ‑ 240 V | The nominal phase voltage that is output in backup power mode. |
Backup power frequency offset | -5 - +5 Hz | The setting value can be used to reduce or increase the nominal backup power frequency (see Technical data) by the offset value. The default value is +3 Hz. Connected loads (e.g., Fronius Ohmpilot) detect active backup power mode based on the changed frequency and react accordingly (e.g., activation of energy-saving mode).
If another AC source is available in the system, the backup power frequency must not be changed. The standard value (+3 Hz) prevents further AC sources from feeding in parallel to the inverter in backup power mode and triggering overvoltages as well as shutting down the dedicated backup power network. |
Backup power undervoltage protection limit value U< [pu] | 0 ‑ 2 %V | This setting value represents the limit value for shutting down backup power mode |
Backup power undervoltage protection time U< | 0.04 ‑ 20 s | Trip time for falling below the backup power undervoltage protection limit value. |
Backup power surge protection limit value U> [pu] | 0 ‑ 2 %V | This setting value represents the limit value for shutting down backup power mode |
Backup power surge protection time U> | 0.04 ‑ 20 s | Trip time for exceeding the backup power surge protection limit value. |
Backup power restart delay | 0 ‑ 600 s | Waiting time for restarting backup power mode following a shutdown. |
Backup power restart attempts | 1 ‑ 10 | The max. number of automated restart attempts. Once the max. number of automated restart attempts has been reached, service message 1177 must be manually acknowledged. |
Backup power external frequency monitoring
| Off | Function is deactivated |
On | For Full Backup power mode in Italy, external frequency monitoring must be activated. The mains frequency is checked before ending backup power mode. If the mains frequency is within the permitted limits, the loads are connected to the public grid. | |
Backup power short circuit trip time | 0.001 ‑ 60 s | If a short circuit occurs during backup power mode, backup power mode is interrupted within the set time. |
In Germany, new rules for charging batteries came into force on January 1, 2024. The maximum charging power from public grids is 4.2 kW when controlled in accordance with Section 14a of the EnWG (Energy Industry Act).
The inverter must establish a connection to Fronius 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. It is important not to use more than the allowed 4.2 kW charging power.

Battery SoC settings
If the SoC Limit Mode is set to Auto, the values SoC Minimum and SoC Maximum are preset according to the technical specifications of the battery manufacturer.
If the SoC Limit Mode is set to Manual, the values SoC Minimum and SoC Maximum can be changed after consultation with the battery manufacturer within the framework of their technical specifications. In a backup power situation, the set values are not taken into account.
The setting Allow battery charging from other generators in the home network activates/deactivates charging of the battery from other generators.
The power consumption of the Fronius inverter can be restricted by specifying a value in the Max. Charging Power from AC field. As a maximum, a power consumption equal to the AC rated power of the Fronius inverter is possible.
The setting Allow battery charging from public grid + Allow battery charging from other generators in the home network activates/deactivates the charging of the battery from the public grid and, if present, from other generators in the home network.
The normative or compensatory specifications must be taken into account for this setting. Irrespective of this setting, necessary service-related charging from the public grid is performed (e.g., forced re-charging to protect against deep discharge).
SoC warning level
In backup power mode, a warning is emitted when this residual battery capacity is reached.
Reserve Capacity
The set value results in a residual capacity (depending on the capacity of the battery) that is reserved for backup power situations. The battery is not discharged below the residual capacity in grid connected mode.
IMPORTANT!
Fronius accepts no liability for damage to third-party batteries.
Time-dependent battery control
Using the Time-dependent battery control, it is possible to specify, restrict, or prevent the charging/discharging of the battery at/to a defined power.
IMPORTANT!
The defined regulations for battery control have the second lowest priority after Self-Consumption Optimization. Depending on the configuration, the regulations may not be fulfilled due to other settings.
The timing of when the regulation applies is set in the Time input fields and by selecting the days of the week.
It is not possible to define a time window beyond midnight (00:00).
Example: Two entries are needed to set a regulation of 22:00 to 06:00: "22:00 - 23:59" and "00:00 - 06:00".
The following examples serve to explain the energy flows. Efficiency levels are not taken into account.

A regulation always consists of a restriction or specification, and the time and days of the week when the regulation is active. The time of regulations with the same restriction (e.g., max. charging power) must not overlap.
Max. charging and discharging limits
One max. charging and one max. discharging power can be configured at the same time.
Specify charging range
It is possible to define a charging range using a min. and max. charging limit. In this case, it is not possible to discharge the battery.
Specify discharging range
It is possible to define a discharging range using a min. and max. discharging limit. In this case, it is not possible to charge the battery.
Specify a defined charge
It is possible to specify a defined charging power by setting the min. and max. charging power to the same value.
Specify a defined discharge
It is possible to specify a defined discharging power by setting the min. and max. discharging power to the same value.
Possible applications
The regulations in the Battery Management menu area enable optimal 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 discharge of the battery | 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 the device is already being fully utilized through discharging.
Since it does not 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 considered to be a load. The priority for the load management of the Fronius 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 prioritized 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 after 60 seconds.
Self-Consumption Optimization
Set the operating mode to Manual or Automatic. The inverter always adjusts to the set Target value at feed-in point. In Automatic operating mode (factory setting), an adjustment is made to 0 W at the feed-in point (max. self-consumption).
Target value at feed-in point
If Manual has been selected under Self-Consumption Optimization, the Operation 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.

Do not give the access code to third parties and/or unauthorized persons.
Energy companies or grid operators can prescribe feed-in limits for an inverter (e.g., max. 70% of the kWp or max. 5 kW).
The feed-in limit takes account of self-consumption in the household before the power of an inverter is reduced:
The inverter ensures that the PV power that cannot be fed into the public grid is used by the Fronius Ohmpilot so that it does not go to waste. The feed-in limit only becomes active if the power of feeding in is higher than the set power reduction.
Total DC power of the entire system
Input field for the total DC power of the entire system in Wp.
This value is used if the Maximum grid power feed is specified in %.
Power Control deactivated
The inverter converts all available PV energy and feeds it into the public grid.
Power Control activated
Feeding in limited with the following selection options:
Export limit control (soft limit)
If this value is exceeded, the inverter readjusts down to the set value.
Export limit protection (hard limit trip)
If this value is exceeded, the inverter switches off within max. 5 seconds. This value must be higher than the value set for Export limit control (soft limit).
Maximum grid power feed
Input field for the Maximum grid power feed in W or % (setting range: -10 to 100%).
If there is no meter in the system or if a meter has failed, the inverter limits the power of feeding in to the set value.
Activate the function Reduce inverter power to 0% if Smart Meter connection has been lost for control in the event of a Fail-Safe.
The use of WiFi for communication between the Smart Meter and the inverter is not recommended for the Fail-Safe function. Even short-term disconnections can cause the inverter to shut down. This problem is particularly common with weak WiFi signal strengths, a slow or overloaded WiFi connection, and automatic channel selection of the router.
Limit multiple inverters (only soft limit)
Control of the dynamic feed-in limit for several inverters, for details on configuration, see chapter Dynamic feed-in limit with multiple inverterson page (→).
"Total Power Limit"
(feed-in limit 0 kW)
Explanation
No power (0 kW) may be fed into the public grid at the grid feed-in point. The load requirement in the home network (12 kW) is supplied by the power generated by the inverter.
"Limit per phase – asymmetric generation"
(feed-in limit 0 kW per phase) – asymmetric
Explanation
The load requirement in the home network per phase is determined and supplied.
"Limit per phase – asymmetric generation"
(feed-in limit 1 kW per phase) – asymmetric
Explanation
The load requirement in the home network per phase is determined and supplied. In addition, the excess production (1 kW per phase) is fed into the public grid in accordance with the maximum permitted feed-in limit.
"Limit per phase – weakest phase"
(feed-in limit 0 kW per phase) – symmetrical
Explanation
The weakest phase in the load requirement in the home network is determined (phase 1 = 2 kW). The result of the weakest phase (2 kW) is applied to all phases. Phase 1 (2 kW) can be supplied. Phase 2 (4 kW) and phase 3 (6 kW) cannot be supplied, power from the public grid is required (phase 2 = 2 kW, phase 3 = 4 kW).
"Limit per phase – weakest phase"
(feed-in limit 1 kW per phase) – symmetrical
Explanation
The weakest phase in the load requirement in the home network is determined (phase 1 = 2 kW) and the max. permitted feed-in limit (1 kW) is added. The result of the weakest phase (2 kW) is applied to all phases. Phase 1 (2 kW) can be supplied. Phase 2 (4 kW) and phase 3 (6 kW) cannot be supplied, power from the public grid is required (phase 2 = 1 kW, phase 3 = 3 kW).

The inverter can be used as a primary device to control dynamic feed-in limits for additional Fronius inverters (secondary devices) so that feed-in limits prescribed by energy companies or utilities can be centrally managed. This control refers to the Soft Limit feed-in limit (see Feed-in limit. The following requirements must be met:
IMPORTANT!
Only one primary meter is required for the primary device.
IMPORTANT!
If a GEN24 inverter with a battery is connected, it must be used as the primary device for dynamic feed-in limits.
The dynamic feed-in limit is available for the following device combinations:
Primary device | Secondary devices |
|---|---|
Fronius GEN24 | Fronius GEN24, Fronius Verto, Fronius Tauro, Fronius SnapINverter with Fronius Datamanager 2.0* |
Fronius Verto | Fronius GEN24, Fronius Verto, Fronius Tauro, Fronius SnapINverter with Fronius Datamanager 2.0* |
Fronius Tauro | Fronius GEN24, Fronius Verto, Fronius Tauro, Fronius SnapINverter with Fronius Datamanager 2.0* |
Primary meter
The Fronius Smart Meter acts as the only primary meter and is connected directly to the primary device. The Smart Meter measures the total output power of all inverters into the grid and passes this information to the primary device via Modbus.
Primary device
The export limitation is configured on the user interface of the inverter:
The primary device automatically scans the network for available secondary devices. A list of the inverters found is displayed. Click the refresh button to perform the search again.
Secondary device
A secondary device takes over the export limitation of the primary device. No data are sent to the primary device for the export limitation. The following configurations must be set for the power control:
IMPORTANT!
The secondary device automatically stops energy being fed into the grid in the event of a communication failure if the Modbus control does not send a signal to the inverter.
General

If the rule is activated, the DNO feedback output (pin 1 recommended) must be configured (e.g., for operating a signal device).
The following rules for power management can be defined:
The data format *.fpc is supported for the Import and Export of defined rules.
If there is an active rule for the control of the inverter, this is shown in the overview of the user interface under Device State.
Controlling Priorities
Used to set controlling priorities for I/O power management (DRM or ripple control receiver), the export limitation, and control via Modbus.
1 = highest priority, 3 = lowest priority
Local priorities of the I/O power management, the export limitation, and the Modbus interface are overridden by cloud control commands (regulatory purposes and virtual power plants) – see Cloud control on page (→) and by backup power.
The controlling priorities are differentiated internally by power control and inverter shutdown. Inverter shutdown always takes precedence over power control. An inverter shutdown command is always executed, regardless of the priority.
Power controlThe ripple control signal receivers and the I/O terminals of the inverter can be connected to one another as shown in the connection diagram.
For distances of over 10 m between the inverter and the ripple control signal receiver, a CAT 5 STP cable is recommended as a minimum and the shielding must be connected on one side at the push-in terminal of the data communication area (SHIELD).

Description
The Autotest makes it possible to check the Italian protection function, required by the applicable standard for monitoring the voltage and frequency limit values of the inverter during commissioning. In normal operation, the inverter constantly checks the real-time actual value of the voltage and frequency of the grid.
Once the Autotest has started, different individual tests are carried out automatically, in succession. Depending on the grid conditions, the duration of the test is approximately 15 minutes.
IMPORTANT!
In Italy, the inverter may only be commissioned following a successfully completed Autotest (CEI 0-21). If an Autotest is not passed, grid power feed operation may not take place. Once the Autotest is started, it must be completed successfully. The Autotest cannot be started during backup power mode.
