If the Wi-Fi module fails to connect to the network after entering the correct router hotspot and password, the password might contain special characters not supported by the module. Change the password to include only Arabic numerals or uppercase/lowercase letters.
What to do if my Goodwe GW80K-MT has Relay-Check Failure?
If your Goodwe Inverter shows a Relay-Check Failure: 1. Turn off the DC switch of the inverter. 2. Wait until the inverter's LCD light is off. 3. Turn on the DC switch and ensure it is connected.
What to do if my Goodwe GW80K-MT shows 'Utility Loss'?
If your Goodwe Inverter displays a 'Utility Loss' error, it means it's not connected to the power grid. First, check if the power grid cable is properly connected. Also, verify the availability of the power grid itself.
Why is my Goodwe Inverter showing a 'Vac Failure'?
A 'Vac Failure' on your Goodwe Inverter indicates a grid voltage issue. The inverter should automatically restart within 5 minutes if the grid returns to normal. Ensure the grid voltage conforms to the specified requirements and that the neutral (N) and protective earth (PE) wires are securely connected.
How to fix a 'Fac Failure' on a Goodwe GW80K-MT Inverter?
If your Goodwe Inverter is showing 'Fac Failure', this means the grid is not connected. Check the grid connection cables and verify the availability of the grid.
What to do if my Goodwe GW80K-MT Inverter is overheating?
If your Goodwe Inverter is experiencing an 'Over Temperature' error, it means the internal temperature is higher than the specified normal value. Try to reduce the ambient temperature or move the inverter to a cooler location.
What does 'Ground I Failure' mean on my Goodwe GW80K-MT?
If your Goodwe Inverter displays 'Ground I Failure', it indicates that the ground current is too high. Disconnect the inputs from the PV generator and inspect the peripheral AC system. Once the problem is resolved, reconnect the PV panel and check the Inverter status.
Why is my Goodwe GW80K-MT showing 'PV Over Voltage'?
If your Goodwe Inverter is showing 'PV Over Voltage', verify that the PV open circuit voltage is not higher or too close to the maximum input voltage.
How to troubleshoot a 'Relay-Check Failure' on a Goodwe GW80K-MT Inverter?
If your Goodwe Inverter displays 'Relay-Check Failure', turn off the DC switch of the inverter and wait until the LCD light turns off. Then, turn the DC switch back on, ensuring it is properly connected.
