  If your Goodwe Inverter is showing a System Failure, here are a few things you can check: 1. First, disconnect the DC switch and take off the DC connector. Then, check the impedance between PV (+) & PV (-) to earth. 2. If the impedance is less than 100 kΩ, check the insulation of the PV string wiring to the earth. 3. If the impedance is larger than 100 kΩ, check AC wiring after taking off the AC connector and measuring the impedance between neutral and PE. If it is larger than 10 kΩ, check AC wiring.

  If your Goodwe Inverter reports a Utility Loss, follow these steps: 1. Disconnect the DC switch and take off the AC connector. 2. Measure the voltage between line and neutral in the connector to ensure it conforms to the grid-connected specification of the inverter. 3. If it doesn't, check if the distribution switch is connected and the grid is normal. 4. If it does, reconnect the AC connector and DC connector.

  If your Goodwe Inverter displays an AC Voltage Failure, here’s what you can do: 1. Disconnect the DC switch and take off the AC connector. 2. Measure the voltage between line and neutral in the connector to ensure it conforms to the grid-connected specification of the inverter. 3. If it doesn't, check the grid wiring. 4. If it does, connect the AC connector and reconnect the DC switch; the inverter will connect automatically.

What to do if Goodwe Inverter shows 'Ground I Failure'?
- M
  Molly DuncanSep 9, 2025
  If your Goodwe Inverter is showing a 'Ground I Failure', it means that the ground current is too high. Unplug the inputs from the PV generator and check the peripheral AC system. After clearing the problem, reconnect the PV panel and check the Inverter status.
