Webserver menu – Service menu – General
In the service menu, the installer will find more options for configuring the inverter. Configuring these settings requires precise knowledge of the requirements of the public grid specified by the energy supply company (e.g. reduction of active power, setting of parameters specified by the energy supply company).
INFO
The settings in this menu require special knowledge of the grid configuration.
- Energy management (only configurable with service code)
Select the connected energy meter on the inverter and the restriction for feeding into the public grid.
INFO
You will find a list of approved energy meters and their purpose in the download area for the product on our website at https://www.kostal-solar-electric.com

Parameter |
Explanation |
|---|---|
Energy meter | Selection of connected energy meter. |
Sensor position | Select the position of the energy meter fitted in the building services. The energy meter must be installed at the grid connection point (position 2). Position 1 (home consumption path) is not possible. Grid connection point = position 2 |
- Battery settings
If a battery is connected to the inverter, its behaviour and usage of the battery can be configured here.
IMPORTANT INFORMATION
If a battery is set up at a later date via the Webserver or inverter, use the DC switch to switch the inverter off and on again after configuration so that the settings are adopted.

Explanation |
|---|---|
Battery type | Select the battery connected to the inverter. |
Battery control | The battery can be controlled by an external battery management system (e.g. energy supplier). In this case, the charge/discharge capacity of the battery is controlled by the external supplier. The plant owner then receives remuneration for the energy provided, e.g. from the external supplier.External battery control Internal (standard): The external control is deactivated. Via digital I/O: External battery management is carried out via the digital inputs on the Smart Communication Board (terminal X401) of the inverter. A presetting can be selected or the digital inputs can be configured according to the provider's specifications. Via Modbus (TCP): The external battery management is provided via the Modbus RTU protocol. The control signals are received via the LAN interface. If there are no control signals, the system switches to internal control. It is still possible to read out the device status in parallel using Modbus (TCP)/SunSpec. |
Battery discharge as of grid demand of [W] | Input of a minimum grid demand value as of which the battery is used. (Standard 50 W.) Example: If a value of 200 W is set, the battery can only be released to cover the home consumption when the measured grid demand from the public grid exceeds 200 W. The battery is blocked again for home consumption when the grid demand falls 50 W below the set value (in this example 150 W). |
Min. state of charge (SoC) [%] | Set the minimum depth of discharge of the battery. If the smart battery control is also activated, the depth of discharge is automatically adjusted depending on the weather conditions and forecast to make optimum use of the battery. |
Time-controlled battery usage | The charging and discharging operation can be configured very flexibly at different times (tariff periods). There are times when the costs of electricity procurement are relatively high (different tariff models). Therefore, it may make sense to allow the battery to discharge during these periods and to allow charging outside of these periods. The times set here can be overridden by the specifications of an activated external battery management system. Battery charge blocked: battery discharge permitted in the event of demand from house. Battery discharge blocked: battery charge permitted in the event of excess power. |
Advanced battery options – Service charging (only possible with service code) | Start service charging to 100% If the SoC of the battery is very low during initial commissioning, this function can be used to charge the battery to 100% once. This is done with solar power or, if there is not enough solar energy available, with energy from the public grid. In this case, "Service charging" is displayed on the inverter. |
- External hardware settings (only configurable with service code)
Setting hardware settings.
Parameter | Explanation |
|---|---|
Residual current protection equipment | Compatibility of type A RCD: If this function has been activated, type A RCDs can be used as residual current protection equipment. In such cases, the inverter shuts down when the residual current becomes incompatible with a type A RCD. If the function is deactivated, a type B RCD must be used as residual current protection equipment if an RCD is stipulated. |
- Digital inputs (only configurable with service code)

External battery control |
If you have activated external control via the digital I/O ports in the "Battery settings" menu, you can define the functions of the inputs here. Assign the desired charge or discharge power to the inputs. |
- CEI inputs
Terminal for ripple control receiver CEI for Italy.
Parameter | Explanation |
|---|---|
Activate CEI inputs | Activate the CEI input (terminal X403). The switchable shutdown limits must be configured under "Grid and system protection". |
- Evaluation of overvoltage protection
Activate the evaluation of an external message signal. The inverter can evaluate the message output of the overvoltage modules (SPD) and output a message if an event occurs. Information on connection and wiring can be found under Connecting the signal contact for the external overvoltage protection (SPD – Surge Protective Device).
INFO
The setting can only be carried out by an installer with a service code.
Evaluation of the external message signal | Activate the function |
The monitor signal is interconnected as | Select overvoltage module switching status Normally open contact (NO) Normally, the contact is open. If an error occurs, the contact closes and the inverter issues a message. Normally closed (NC). Normally, the contact is closed. If an error occurs, the contact opens and the inverter issues a message. |
- Extra options
This function can be used to release additional options for the inverter.
