What does internal comm loss mean on Goodwe Inverter?
- J
  Jordan MendezSep 14, 2025
  An 'Internal Comm Loss' error on your Goodwe Inverter can be caused by several issues, including frame format errors, parity checking errors, CAN bus offline problems, hardware CRC errors, incorrect send/receive control bit settings, or transmitting to a unit that is not allowed. Disconnect the AC output switch and DC input switch, then connect them again after 5 minutes. If the problem persists, 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.

Why is my Goodwe ES Inverter showing a Grid Undervoltage error?
- V
  vancechristopherNov 25, 2025
  A Grid Undervoltage error on your Goodwe Inverter means that the grid voltage is lower than the permissible range, or the duration of low voltage exceeds the requirement of LVRT. If the problem occurs occasionally, it may be due to a temporary issue with the utility grid, and the inverter should recover automatically when the grid returns to normal. If the problem occurs frequently, verify that the grid voltage is within the permissible range and contact the local power company if it isn't. If the grid frequency is within range, you might need to modify the undervoltage protection threshold, LVRT, or disable the undervoltage protection function, but only after getting approval from the local power company. Also, check whether the AC breaker and the output cables are securely and correctly ...

How to fix AC HCT Check abnormal on Goodwe ES Inverter?
- K
  kevin68Sep 14, 2025
  If your Goodwe Inverter is showing an 'AC HCT Check abnormal' error, it means that the sampling of the AC HCT is abnormal. Disconnect the AC output switch and DC input switch, then connect them again after 5 minutes. If the problem persists, contact the dealer or the after-sales service.

Why Goodwe Inverter ES/Battery not charge when PV?P-load?
- T
  Tammy WhiteSep 23, 2025
  If the ES/Battery is not charging when PV?P-load, check the following: 1. Verify that the charge voltage is set correctly. 2. Confirm whether the settings are configured for charge time only. 3. Check if the battery is fully charged or if the battery voltage has reached the specified charge voltage.

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 to do if Goodwe Inverter ES does not start up with ONLY PV connected?
- K
  Kyle WellsSep 23, 2025
  If the Goodwe Inverter ES does not start up with ONLY PV connected, make sure the voltage of PV is higher than 125V. If the voltage is OK, but the problem persists, contact GoodWe after-sales services.

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.
