What to do if my Goodwe GW3600D-NS Inverter displays 'PV Over Voltage'?
If your Goodwe inverter is showing a 'PV Over Voltage' error: 1. Check if the PV open circuit voltage is higher than or too close to the maximum input voltage. 2. If the issue persists even when the PV voltage is less than the maximum input voltage, contact your local service office for assistance.
What to do if my Goodwe GW3600D-NS Inverter 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 to do if my Goodwe GW3600D-NS displays 'Utility Loss'?
If your Goodwe inverter indicates a 'Utility Loss', please check the following: 1. Ensure the inverter is properly connected to the power grid. 2. Verify that the power grid is connected to the cable. 3. Confirm the availability of the power grid.
What to do if my Goodwe GW3600D-NS displays 'Vac Failure'?
If your Goodwe inverter is showing a 'Vac Failure', here are some things to check: 1. The PV Inverter will automatically restart within 5 minutes if the grid returns to normal. 2. Ensure that the grid voltage conforms to the specified requirements. 3. Verify that the neutral (N) wire and PE cable are properly connected. 4. If the problem persists, contact your local service office for further assistance.
What to do if my Goodwe GW3600D-NS shows 'Isolation Failure'?
If your Goodwe inverter displays an 'Isolation Failure', follow these steps: 1. Check the impedance between the ground and PV (+) & PV (-). The impedance value must be greater than 100kΩ. Ensure the inverter is properly grounded. 2. If the problem persists, contact your local service office for assistance. Additionally, the inverter has a built-in buzzer that will sound continuously for 1 minute upon failure. If the fault isn't resolved, the buzzer will sound every 30 minutes. You can also add the inverter to a monitoring platform and set up alarm reminders to receive email notifications about alarm information.
What to do if my Goodwe Inverter has no display?
If your Goodwe Inverter's display is not working: 1. Turn off the DC switch and unplug the DC connector, then measure the voltage of the PV array. 2. Plug in the DC connector and turn on the DC switch. 3. If the PV array voltage is lower than 250V, check the configuration of the inverter module.
What does Ground I Failure mean on Goodwe Inverter, 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 GW3600D-NS 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 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.
