The inverter detects the voltage of PV+ to ground and PV- to ground, and calculates the resistance of PV+ and PV- to ground respectively. 2) Power off the DC and AC side of the inverter, wait for 10 minutes and reconnect the DC cable, make sure it is tightly connected, and. . Knowing the inverter fault code helps users to stay calm when facing situations where a fault may occur and then deal with it appropriately, avoiding the occurrence of inverter failure. 3) If the fault cannot be recovered after updating, there should be something abnormal inside the inverter, the inverter needs to be replaced. The grounding of the equipment must comply with local electrical codes.
