What does Large DC of AC current L1 mean on my Goodwe EH Inverter?
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.
What causes a Grid Overfrequency error on a Goodwe EH?
A 'Grid Overfrequency' error on your Goodwe Inverter indicates a utility grid exception where the actual grid frequency exceeds the local grid standard's requirements. If this happens occasionally, it might be a temporary issue, and the inverter should recover automatically. However, if it occurs frequently, check if the grid frequency is within the permissible range. If the grid frequency exceeds the permissible range, contact your local power company. If the grid frequency is within the permissible range, you may need to modify the overfrequency protection threshold or disable the overfrequency protection function after obtaining consent from the local power company.
Why does my Goodwe EH display a Grid Undervoltage error?
The 'Grid Undervoltage' error on your Goodwe Inverter means the grid voltage is lower than the permissible range, or the duration of low voltage exceeds the requirement of LVRT. If this occurs occasionally, it may be a temporary grid issue, and the inverter should recover automatically once the grid is normal. If it occurs frequently, check whether the grid voltage is within the permissible range. If the grid voltage is not within the permissible range, contact the local power company. If the grid frequency is within the permissible range, modify the undervoltage protection threshold, LVRT, or disable the undervoltage protection function, but only after getting approval from the local power company. Also, make sure the AC breaker and output cables are securely and correctly connected.
What should I do if my Goodwe EH Inverter shows a Grid Rapid Overvoltage error?
A 'Grid Rapid Overvoltage' error on your Goodwe Inverter indicates an abnormal or ultra-high grid voltage. If this occurs occasionally, it may be a temporary utility grid issue, and the inverter will recover automatically once the grid returns to normal. If it happens 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, modify the grid overvoltage rapid protection threshold only after obtaining consent from the local power company.
What does a Grid Underfrequency error mean on my Goodwe EH?
A 'Grid Underfrequency' error on your Goodwe Inverter indicates a utility grid exception where the actual grid frequency is lower than the local grid standard's requirement. If the problem occurs occasionally, the utility grid may be temporarily abnormal, and the inverter will recover automatically after detecting that the utility grid is 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 underfrequency protection threshold or disable the underfrequency protection function after obtaining the consent of the local power company.
What does Flash Fault mean on my Goodwe EH?
Flash Fault on Goodwe Inverter means that the internal Flash storage is abnormal. To solve this problem, disconnect the AC output switch and DC input switch, then connect them 5 minutes later.
What does AC HCT Check abnormal mean on my Goodwe Inverter?
AC HCT Check abnormal on Goodwe Inverter means that the sampling of the AC HCT is abnormal. To solve this problem, disconnect the AC output switch and DC input switch, then connect them 5 minutes later.
What does GFCI HCT Check abnormal mean on my Goodwe EH?
GFCI HCT Check abnormal on Goodwe Inverter means that the sampling of the GFCI HCT is abnormal. To solve this problem, disconnect the AC output switch and DC input switch, then connect them 5 minutes later.
What does Grid Frequency Instability mean on my Goodwe EH Inverter?
A 'Grid Frequency Instability' error on your Goodwe Inverter indicates a utility grid exception where the actual grid frequency change rate does not meet the local grid standard's requirements. If this occurs occasionally, the utility grid may be temporarily abnormal, and the inverter will recover automatically after detecting that the utility grid is 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.
What to do if my Goodwe EH shows an Abnormal Ground error?
An 'Abnormal Ground' error on your Goodwe Inverter can be caused by: 1. A poorly connected PE cable on the inverter. 2. Reversed L and N cable connections when the PV string output is grounded. To resolve this, check: 1. That the inverter's PE cable is properly connected. 2. Whether the L and N cables are reversed if the PV string output is grounded.
