To integrate the device into the FEMS, please configure it via the web interface. You can access this by calling up the IP address of the inverter in the browser. We recommend setting the assignment of the IP address to "Automatic" when commissioning the device.

To be able to access the web interface, your PC/notebook/smartphone must be in the same network as the inverter.

We recommend deactivating DHCP for the inverter in the router settings so that it always retains the same IP address.

3.2. Ping test

To test the configuration, we recommend pinging the inverter in the local customer network.

In the example below, the inverter uses the address 192.168.178.59.
