What causes a large DC of AC current L1 error on a Goodwe ES?
- D
  Daniel MartinezSep 13, 2025
  A 'Large DC of AC current L1' error on your Goodwe Inverter indicates that the DC component of the output current exceeds the safety or default range. If the problem is caused by an external fault like a utility grid exception or frequency exception, the inverter will recover automatically after solving the problem. If the problem occurs frequently and the PV station cannot work properly, contact the dealer or the after-sales service.

How to fix 'Low Insulation Res.' error on my Goodwe ES Inverter?
- K
  Karen BirdAug 25, 2025
  A 'Low Insulation Res.' error on your Goodwe Inverter indicates that the PV string is short-circuited to PE, or the PV system is in a moist environment with the cable not well insulated to the ground. Check if the resistance of the PV string to PE exceeds 50kΩ; if not, check for a short circuit point. Also, ensure the PE cable is correctly connected. If the resistance is lower on rainy days, reset the ISO.

What causes Grid Overvoltage on a Goodwe Inverter and how to fix it?
- T
  Tonya OwenAug 26, 2025
  A Grid Overvoltage error on your Goodwe Inverter occurs when the grid voltage exceeds the permissible range, or the duration of high voltage exceeds the requirement of HVRT. If this problem occurs occasionally, the utility grid may be temporarily abnormal, and the inverter will recover automatically once the grid returns to normal. If the problem occurs frequently, check whether the grid voltage is within the permissible range. If it exceeds the limit, contact your local power company. If the grid frequency is within range, you can modify the overvoltage protection threshold, HVRT, or disable the overvoltage protection function after obtaining consent from the local power company. Also, check that the AC breaker and output cables are securely and correctly connected.

What to do about Grid Overfrequency on my Goodwe Inverter?
- L
  Laura JonesAug 27, 2025
  A Grid Overfrequency error on your Goodwe Inverter indicates a utility grid exception where the actual grid frequency exceeds the requirement of the local grid standard. If this occurs occasionally, the utility grid may be temporarily abnormal, and the inverter should recover automatically once the grid returns to normal. However, if the problem occurs frequently, check whether the grid frequency is within the permissible range and contact the local power company if it exceeds the limit. If the grid frequency is within range, you can modify the overfrequency protection threshold or disable the overfrequency protection function after obtaining consent from the local power company.

How to resolve Grid Underfrequency issues with a Goodwe ES Inverter?
- D
  Danielle PattersonAug 27, 2025
  A Grid Underfrequency error on your Goodwe Inverter signifies a utility grid exception where the actual grid frequency is lower than the requirement of the local grid standard. If the problem occurs occasionally, the utility grid may be temporarily abnormal, and the inverter will recover automatically after the grid returns to normal. If the problem occurs frequently, check whether the grid frequency is within the permissible range and contact the local power company if it is not. You can also modify the underfrequency protection threshold or disable the underfrequency protection function after obtaining consent from the local power company, or close the "Grid Underfrequency" function.

What causes a grid overfrequency error on a Goodwe ES?
- A
  Allen HintonSep 9, 2025
  A grid overfrequency error on your Goodwe Inverter is typically due to a utility grid exception, where the actual grid frequency exceeds the requirement of the local grid standard. If this occurs occasionally, it may be a temporary issue with the utility grid, and the inverter will recover automatically once the grid returns to normal. If the problem occurs frequently, check whether the grid frequency is within the permissible range. If the grid frequency exceeds the permissible range, contact the local power company. If the grid frequency is within the permissible range, modify the overfrequency protection threshold or disable the overfrequency protection function after obtaining the consent of the local power company.

What to do if there is a utility loss with my Goodwe ES?
- W
  wandersonSep 6, 2025
  If you're experiencing a utility loss with your Goodwe Inverter, it could be due to a failure in the utility grid power. In this case, the alarm should clear automatically once the grid power is restored. Alternatively, the AC cable might be disconnected, or the AC breaker could be off. Ensure the AC cable is properly connected and the AC breaker is turned on.

What to do if my Goodwe ES Inverter displays a grid rapid overvoltage error?
- X
  xnelsonSep 7, 2025
  A 'Grid Rapid Overvoltage' error on your Goodwe Inverter suggests that the grid voltage is either abnormal or ultra-high. If this happens occasionally, it might be a temporary issue with the utility grid, and the inverter should automatically recover when the grid returns to normal. If the problem occurs frequently, check whether the grid voltage is within the permissible range. If the grid voltage exceeds the permissible range, contact the local power company. If the grid voltage is within the permissible range, modify the grid overvoltage rapid protection threshold after obtaining the consent of the local power company.

What does Abnormal GFCI 30mA mean on my Goodwe ES Inverter?
- J
  Joshua MooreSep 1, 2025
  An Abnormal GFCI 30mA error on your Goodwe Inverter indicates that the input insulation impedance to the ground decreases when the inverter is working. If the problem occurs occasionally, it may be caused by a cable exception, and the inverter will recover automatically after the problem is resolved. If the problem occurs frequently or persists, check whether the impedance between the PV string and PE is too low.

What does Grid 10min Overvoltage mean on my Goodwe Inverter?
- D
  Derrick KirbyAug 31, 2025
  A Grid 10min Overvoltage error on your Goodwe Inverter indicates that the moving average of grid voltage in 10 minutes exceeds the range of safety requirements. If the problem occurs occasionally, the utility grid may be abnormal temporarily, and the inverter will recover automatically after the grid returns to normal. If the problem occurs frequently, check whether the grid voltage is within the permissible range. Contact the local power company if the grid voltage exceeds the permissible range. If the grid voltage is within the permissible range, modify the grid overvoltage rapid protection threshold after obtaining consent from the local power company.
