What to do if my Goodwe DNS 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 Inverter 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 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.
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 to do if my Goodwe DNS displays 'Fac Failure'?
If your Goodwe inverter is showing a 'Fac Failure', verify the following: 1. The inverter is connected to the grid. 2. The power grid is connected to the cable. 3. The power grid is available.
What to do if my Goodwe DNS 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 DNS 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 DNS Inverter 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.
