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.
Copyright of these operating instructions remains with the manufacturer.
Text and illustrations were accurate at the time of printing, subject to change.
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 solar modules into alternating current. This alternating current is fed into the public grid and synchronized with the mains voltage in use.
The inverter is intended for use in grid-connected photovoltaic systems.
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 or fed into the grid.
When its temperature gets too high, the inverter automatically reduces the output 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.
The following data can be called up via mDNS: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.
Intended use also means:Follow all grid operator regulations regarding energy fed into the grid and connection methods.

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 alarms 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 at least 100 mA, taking into account national provisions.

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. |

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

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

DNO feedback
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.
