What causes an Isolation Fail error on a Goodwe GW10KT-DT, and how can I fix it?
- J
  Jeremy SparksSep 10, 2025
  An Isolation Fail error on your Goodwe Inverter may be caused by a short-circuited PV system to the ground. Check whether the PV input cables are broken. It can also happen if the PV system is in a moist environment and the circuit is not well insulated to the ground. Verify that the module frames and the metal bracket are securely grounded, and check whether the AC side is properly grounded.

Why is my Goodwe GW10KT-DT showing an Over Temperature error?
- J
  Joseph BarrettSep 8, 2025
  An Over Temperature error on your Goodwe Inverter can occur if the inverter is installed in a place with poor ventilation. Check the installation environment and space of the inverter, ensuring that the ventilation meets heat dissipation requirements. The ambient temperature may also be too high; make sure that the fans are working properly and are not covered or blocked. Also, check whether the operating ambient temperature is too high.

What to do if my Goodwe GW10KT-DT shows a Utility Loss error?
- R
  ryangreenSep 7, 2025
  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.

What to do if my Goodwe GW10KT-DT Inverter shows 'Utility Loss'?
- R
  Renee ArnoldAug 22, 2025
  If your Goodwe Inverter displays a 'Utility Loss' error, it could be due to several reasons. First, check if there is a power failure in the utility grid by checking other electrical devices. Second, ensure that the AC circuit or AC breaker is properly connected. Finally, verify that the phase sequence of the AC cables is correctly connected, and the neutral wire and PE cable are firmly connected.

What does 'Ground I Fail' mean on my Goodwe GW10KT-DT Inverter?
- M
  Michael PriceAug 31, 2025
  If your Goodwe Inverter displays 'Ground I Fail', it indicates that the input insulation impedance to the ground is decreasing during operation. Check if the inverter's working environment meets the requirements; for example, high humidity on rainy days can cause this. Also, ensure that the components and the AC side are properly grounded.
