What does LVRT Undervoltage mean on my Goodwe ES?
An LVRT Undervoltage error on your Goodwe Inverter indicates a utility grid exception where the duration of the utility grid exception exceeds the set time of LVRT. If the problem occurs occasionally, the utility grid may be abnormal temporarily, and the inverter will recover automatically after the grid returns to normal.
What to do if AC HCT Check is abnormal on Goodwe Inverter?
If your Goodwe Inverter displays an abnormal AC HCT Check, it indicates 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.
What does Large DC of AC current L1 mean on my Goodwe ES Inverter?
A 'Large DC of AC current L1' error on your Goodwe Inverter means that the DC component of the output current exceeds the safety range 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 to do if my Goodwe Inverter shows a Utility Loss?
If your Goodwe Inverter displays a Utility Loss error, it indicates that the utility grid power has failed. This alarm will automatically clear once the grid power supply is restored. Alternatively, this error can appear if the AC cable is disconnected, or the AC breaker is off. In this case, you should check whether the AC cable is properly connected and the AC breaker is on.
What does Abnormal GFCI 30mA mean on my Goodwe ES Inverter?
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 Frequency Instability mean on my Goodwe 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 requirement of the local grid standard. 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 frequency is within the permissible range. Contact the local power company if the grid frequency exceeds the permissible range.
What does Grid 10min Overvoltage mean on my Goodwe Inverter?
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.
What should I do if my Goodwe ES Inverter shows an Abnormal Ground error?
An Abnormal Ground error on your Goodwe Inverter can be caused by a poorly connected PE cable or reversed L and N cable connections when the PV string output is grounded. Check whether the PE cable of the inverter is properly connected. Also, check whether the L cable and N cable are connected reversely if the output of the PV string is grounded.
What causes a Cavity Overtemperature error on a Goodwe ES?
A Cavity Overtemperature error on your Goodwe Inverter can be caused by several factors: the inverter is installed in a place with poor ventilation, the ambient temperature exceeds 60°C, or there is a fault in the internal fan of the inverter. Check the ventilation and the ambient temperature at the installation point. If the ventilation is poor or the ambient temperature is too high, improve the ventilation and heat dissipation.
What does Grid Rapid Overvoltage mean on my Goodwe ES?
A Grid Rapid Overvoltage error on your Goodwe Inverter indicates that the grid voltage is abnormal or ultra-high. 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. 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.
