Configure evaluation of external overvoltage protection in the Webserver

If a surge protection device (SPD) has been installed in your system, you can connect the potential-free signal contact of the surge protection module to terminal X402 of the inverter and monitor the correct functioning of the module. In the event of a fault, the inverter outputs an event code and reports this to the KOSTAL Solar Portal.

You can also set up a switching output for event reporting Set up switched output for reporting events.
