Communication fault with meter unit > Check communication to meter
The inverter is not receiving any data from the energy meter.
Corrective measures:
• Ensure that the energy meter is correctly integrated into the same network as the inverter (see energy meter manual).
• For WLAN connection, improve the WLAN connection quality (e.g. via SMA Antenna Extension Kit) or connect the inverter with the DHCP server(router) via Ethernet.
