What does Ground I Failure mean on Goodwe GW1000-NS, and how can it be fixed?
A 'Ground I Failure' on your Goodwe Inverter indicates that the ground current is too high. Unplug the inputs from the PV generator and check the peripheral AC system. Once the problem is resolved, reconnect the PV panel and check the inverter status.
What does Fac Failure mean on Goodwe Inverter?
A 'Fac Failure' on your Goodwe Inverter means it is not connected to the grid. Check if the power grid is connected to the cable, and check the availability of the power grid.
How to fix a Relay-Check Failure on a Goodwe Inverter?
To address a Relay-Check Failure on your Goodwe Inverter: 1. Turn off the DC switch of the inverter. 2. Wait until the LCD light is off. 3. Turn on the DC switch and ensure it is connected.
What does Isolation Failure mean on my Goodwe GW1000-NS Inverter 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.
What to do if my Goodwe GW1000-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.
Why does my Goodwe GW1000-NS 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 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.
