What does Anti-islanding mean on my Goodwe GW15K-ET?
If your Goodwe Inverter shows an Anti-islanding error, it indicates that the utility grid is disconnected, according to safety regulations, but the grid voltage is maintained due to the loads. Check whether the utility grid is disconnected.
What to do if my Goodwe GW15K-ET Inverter shows Utility Loss?
If your Goodwe Inverter shows a Utility Loss, it could be due to a failure in the utility grid power. The alarm should automatically clear once the grid power is restored. Another cause might be a disconnected AC cable or an AC breaker that is off. Ensure the AC cable is properly connected and the AC breaker is switched on.
Why does my Goodwe GW15K-ET show Grid Overvoltage?
If your Goodwe Inverter is showing a Grid Overvoltage error, it could be because the grid voltage exceeds the acceptable range, or the duration of high voltage surpasses HVRT requirements. If this happens occasionally, it may be a temporary issue with the utility grid, and the inverter should automatically recover once the grid voltage returns to normal. If the problem occurs frequently, verify that the grid voltage is within the permissible range. If it's not, contact your local power company. Also, ensure the AC breaker and output cables are securely and correctly connected.
What causes Grid Overfrequency on a Goodwe GW15K-ET?
If your Goodwe Inverter displays a Grid Overfrequency error, it's likely due to 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 issue, and the inverter should recover automatically once the grid frequency returns to normal. However, if the problem happens frequently, verify that the grid frequency is within the permissible range. If it exceeds the limit, contact your local power company.
Why is my Goodwe GW15K-ET Inverter showing Grid Undervoltage?
If your Goodwe Inverter is showing a Grid Undervoltage error, it might be because the grid voltage is lower than the permissible range, or the duration of low voltage exceeds the LVRT requirement. If this occurs occasionally, it could be a temporary issue with the utility grid, and the inverter should recover automatically once the grid returns to normal. If the problem occurs frequently, check whether the grid voltage is within the permissible range. Also, ensure the AC breaker and the output cables are securely and correctly connected.
What does Grid Rapid Overvoltage mean on Goodwe Inverter?
If your Goodwe Inverter is showing Grid Rapid Overvoltage, it means that the grid voltage is abnormal or ultra-high. If the problem occurs occasionally, the utility grid may be temporarily abnormal. The inverter will recover automatically after detecting that the utility grid is normal. If the problem occurs frequently, check whether the grid voltage is within the allowed range and contact the local power company if it exceeds the permissible range.
How to fix Grid Underfrequency error on Goodwe Inverter?
If your Goodwe Inverter displays a Grid Underfrequency error, it indicates a utility grid exception where the actual grid frequency is lower than the local grid standard's requirement. If this occurs occasionally, it may be a temporary issue, and the inverter should recover automatically once the grid frequency returns to normal. If the problem occurs frequently, check whether the grid frequency is within the permissible range. You can also close the “Grid Underfrequency” function.
Why my Goodwe GW15K-ET displays Cavity Overtemperature?
If your Goodwe Inverter is showing Cavity Overtemperature, it could be due to several reasons: the inverter is installed in a place with poor ventilation, the ambient temperature exceeds 60°C, or there is a fault with the inverter's internal fan. Check the ventilation and ambient temperature at the installation point. If ventilation is poor or the ambient temperature is too high, improve the ventilation and heat dissipation.
What does Grid 10min Overvoltage mean on a Goodwe GW15K-ET Inverter?
If your Goodwe Inverter displays Grid 10min Overvoltage, it indicates that the moving average of grid voltage in 10 minutes exceeds the safety requirements. 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 allowed range and contact the local power company if it exceeds the permissible range.
How to resolve PV Input Overvoltage on Goodwe Inverter?
If your Goodwe Inverter is showing PV Input Overvoltage, it means the PV array configuration is incorrect, and too many PV panels are connected in series in the PV string. Check the serial connection of the PV array. Ensure that the open circuit voltage of the PV string is not higher than the maximum operating voltage of the inverter.
