What causes an Abnormal Ground error on a Goodwe SMT?
An 'Abnormal Ground' error on your Goodwe inverter can be caused by a disconnected PE cable or reversed AC output cables (L and N) when grounding the PV string. Ensure the PE cable of the inverter is properly connected. If the PV string is grounded, confirm that the inverter's AC output cables L and N are not reversed.
Why is my Goodwe Inverter showing Grid Overfrequency?
If your Goodwe Inverter displays a 'Grid Overfrequency' error, it indicates a utility grid exception where the actual grid frequency exceeds the local grid standard's requirements. If this occurs occasionally, it may be a temporary abnormality in the utility grid, and the inverter should automatically recover once the grid returns to normal. However, if the issue persists, verify that the grid frequency is within the permissible range. If the grid frequency exceeds this range, contact your local power company. If the grid frequency is within the permissible range, consider modifying the overfrequency protection threshold or disabling the overfrequency protection function, but only after obtaining consent from the local power company.
What causes Grid 10min Overvoltage on a Goodwe SMT Inverter?
If your Goodwe Inverter shows 'Grid 10min Overvoltage', it means the moving average of the grid voltage over 10 minutes exceeds safety requirements. If this happens occasionally, it might be due to a temporary issue with the utility grid, and the inverter should recover automatically. However, if the problem occurs frequently, check if 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, consider modifying the 10min overvoltage protection threshold after getting consent from the local power company.
Why is my Goodwe SMT Inverter showing Grid Undervoltage?
If your Goodwe Inverter is showing a 'Grid Undervoltage' error, it 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 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 voltage is within the permissible range. If the grid voltage consistently falls outside the permissible range, contact your local power company. If the grid frequency is within range, consider modifying the undervoltage protection threshold, LVRT, or disabling the undervoltage protection function after obtaining consent from the local power company. Also, check the AC breaker and ...
What does L-PE Short Circuit mean on my Goodwe SMT?
An 'L-PE Short Circuit' error on your Goodwe inverter indicates an issue with the live wire connection at the inverter's output terminal. Check the wiring on the grid side and correct any mistakes.
What to do if my Goodwe SMT shows 'Vac Failure'?
If your Goodwe Inverter displays a 'Vac Failure', the inverter will automatically restart within 5 minutes if the grid returns to normal. Also, ensure that the grid voltage conforms to the specifications and that the neutral (N) wire and PE wire are properly connected.
What to do if my Goodwe SMT Inverter shows Utility Loss?
The Goodwe inverter may display a 'Utility Loss' error due to a utility grid power failure or a disconnected AC circuit/breaker. The alarm should clear automatically once the grid power is restored. Ensure the AC cable is properly connected and the AC breaker is switched on.
What causes Grid Rapid Overvoltage on Goodwe Inverter?
A 'Grid Rapid Overvoltage' error on your Goodwe inverter indicates an abnormal grid voltage or that an ultra-high voltage has triggered the fault. If this happens occasionally, it may be due to a short-term grid abnormality, and the inverter should recover automatically. If it occurs frequently, check if the grid voltage is within the allowed range and ensure the AC side circuit breaker and output cables are properly connected.
What does PV Hardware Overcurrent mean on my Goodwe Inverter?
A 'PV Hardware Overcurrent' error on your Goodwe inverter is caused by weak or abnormally changing sunlight. Disconnect the AC output switch and DC input switch, wait 5 minutes, and then reconnect them.
What to do if Goodwe SMT Inverter shows PV String Reversed?
If your Goodwe Inverter is showing 'PV String Reversed (Str1- Str12)', it means that the PV string is connected reversely. Check whether the PV strings are connected reversely.
