Good afternoon. I need your advice as a competent specialist.Installed the sun-12K-SG04LP3-EU inverter (3 phases).At startup, it issues an error F30 (does not see the solar panels), the decoding of the error means the failure of the main AC relay.When the city network is disconnected, the error persists.What to do?
