What to do if my Enphase Inverter does not operate correctly?
- Sshelley08Nov 4, 2025
If your Enphase Inverter isn't working correctly, start by ensuring that AC breakers and disconnects are closed. Check the connection to the utility grid and confirm the utility voltage is within the acceptable range. Verify that AC line voltages at all solar power circuit breakers at the load center and subpanels are within the specified ranges. Also, check the AC line voltage at the junction box for each AC branch circuit to ensure it's within the allowable limits. Disconnect and reconnect the DC PV module connectors. Verify the PV module DC voltage is within the allowable range. Check the DC connections between the microinverter and the PV module. Verify with your utility that line frequency is within range. Visually check that the AC branch circuit connections (Enphase Q Cable and AC c...
