What does ARC Fault mean on a Goodwe GW10K-SDT-20, and how do I fix it?
An ARC Fault error on your Goodwe Inverter suggests that the PV string cables are arcing or are in poor contact. Check whether the PV terminals and cables are connected properly. Clear the error messages.
What does IFan Fail mean on my Goodwe GW10K-SDT-20?
An IFan Fail error on your Goodwe Inverter indicates a fault in the internal fan of the inverter. Restart the inverter and check whether the inverter can work normally.
How to resolve 'Ver. Error' on a Goodwe Inverter?
If your Goodwe Inverter displays a 'Ver. Error', it indicates a wrong software version. Contact after-sales service to upgrade the software.
What does 'Vac Fail' mean on my Goodwe Inverter?
If your Goodwe Inverter shows 'Vac Fail', it means the utility grid voltage is out of the allowed range. Make sure that the grid voltage is within the allowed range. Also, ensure that the phase sequence of the AC cables are connected correctly, and the neutral wire and PE cable are properly and firmly.
What causes 'Fac Fail' on a Goodwe Inverter?
If your Goodwe Inverter shows 'Fac Fail', it indicates that the utility grid frequency is out of the allowed range. Check whether other electrical devices under the same grid connection point is working normally, and whether the main supply is normal. Ensure the grid frequency is within the allowed range and that the phase sequence of the AC cables are connected correctly, and the neutral wire and PE cable are properly and firmly. If the fault happens occasionally, it may be due to instantaneous utility grid frequency change and does not need to be handled.
Why is my Goodwe Inverter showing 'PV Over Voltage'?
If your Goodwe Inverter displays 'PV Over Voltage', it means that too many PV modules are connected in series, causing the open-circuit voltage to exceed the operating voltage. Check whether the PV string input voltage is consistent with the value displayed on the LCD and meets the maximum input voltage requirements.
What does 'ARC Fault' mean on my Goodwe GW10K-SDT-20 and how to fix it?
If your Goodwe Inverter is showing an 'ARC Fault', it could be due to the PV string cables arcing or being in poor contact. Check whether the PV terminals and cables are connected properly. If the fault occurs frequently, contact after-sales service.
What causes a 'DC inject High' error on a Goodwe Inverter?
A 'DC inject High' error on your Goodwe Inverter means that DC injection exceeds the allowed range. Check whether the software version is the latest one. Restart the inverter and check whether the inverter can work properly.
What does Ground I Fail mean on my Goodwe GW10K-SDT-20?
A Ground I Fail error on your Goodwe Inverter means that the input insulation impedance to the ground decreases when the inverter is operating. Check whether the working environment of the inverter meets the requirements. For example, the fault may occur due to high humidity on rainy days. Make sure that the components are properly grounded and the AC side is properly grounded.
What to do if my Goodwe Inverter shows a Utility Loss error?
If your Goodwe Inverter displays a Utility Loss error, it could be due to a utility grid power failure. Check if other electrical devices connected to the same grid connection point are working normally and if the main supply is normal. It could also be due to a disconnected AC circuit or AC breaker, so ensure that the upstream switches of the inverter are connected. Also, verify that the phase sequence of the AC cables are correctly connected, and the neutral wire and PE cable are properly and firmly connected.
