What should I do if the Adapter Box G3 cannot communicate with the inverter?

First check the COM connection and make sure the communication cable is correctly connected.

For inverter communication faults, the manual recommends reconnecting the COM port and restarting the Adapter Box G3. If communication cannot be restored, the installer should be contacted.

For TCP-based inverter communication faults, the manual also recommends checking the router and confirming that the Adapter Box G3 is operating normally in SolaXCloud.
