What to do if my Goodwe Inverter displays a Fac Failure?
- BBrent JohnstonSep 22, 2025
If your Goodwe Inverter displays a 'Fac Failure', the grid may not be connected. Check the grid connection cables and verify the grid's availability.
What to do if my Goodwe Inverter displays a Fac Failure?
If your Goodwe Inverter displays a 'Fac Failure', the grid may not be connected. Check the grid connection cables and verify the grid's availability.
What to do if my Goodwe GW5000D-NS displays a Vac Failure?
If your Goodwe Inverter shows a 'Vac Failure', the inverter will automatically restart within 5 minutes if the grid returns to normal. Ensure the grid voltage meets the required specifications and that the neutral (N) and PE wires are securely connected. If problems continue, contact your local service office.
What to do if my Goodwe GW5000D-NS indicates a Utility Loss?
If your Goodwe Inverter shows a 'Utility Loss', first, make sure that the inverter is connected to the grid. Then, check the cable connection to the power grid and confirm the power grid's availability.
What to do if my Goodwe GW5000D-NS Inverter shows PV Over Voltage?
If your Goodwe Inverter shows a 'PV Over Voltage' error, start by checking if the PV open circuit voltage is too close to, or exceeds, the maximum input voltage. If the problem remains even when the PV voltage is below the maximum input voltage, contact your local service office for further assistance.
What to do if my Goodwe GW5000D-NS Inverter is Over Temperature?
If your Goodwe Inverter is showing an 'Over Temperature' warning, it means the internal temperature is higher than the specified normal value. Try to reduce the ambient temperature and move the inverter to a cooler location. If the issue continues, contact your local service office.
What to do if my Goodwe GW5000D-NS displays 'Ground I Failure'?
If your Goodwe inverter reports a 'Ground I Failure' because the ground current is too high, follow these steps: 1. Unplug the inputs from the PV generator and inspect the peripheral AC system. 2. After resolving the issue, reconnect the PV panel and check the inverter status. 3. If the problem continues, contact your local service office for assistance.
What causes Over Temperature error on Goodwe Inverter and how to fix it?
The 'Over Temperature' error on your Goodwe Inverter indicates that the internal temperature is higher than normal. Try to decrease the ambient temperature or move the inverter to a cooler location.
Why does my Goodwe Inverter show Utility Loss?
A 'Utility Loss' message on your Goodwe Inverter indicates a disconnection from the power grid. Check if the power grid is connected to the cable and verify the availability of the power grid.
What to do if my Goodwe GW5000D-NS displays PV Over Voltage?
If your Goodwe Inverter is showing a 'PV Over Voltage' error, check if the PV open circuit voltage is higher than or too close to the maximum input voltage.
What does Isolation Failure mean on my Goodwe GW5000D-NS and how can I resolve it?
An 'Isolation Failure' on your Goodwe Inverter suggests a problem with the impedance between the ground and PV (+) & PV (-). Check the impedance; the value must be greater than 100kΩ. Also, ensure the inverter is properly grounded.
