Why am I getting a PV Input Overvoltage error on my Goodwe ES Inverter?
A PV Input Overvoltage error on your Goodwe Inverter indicates that the PV array configuration is incorrect, meaning too many PV panels are connected in series in the PV string. To resolve this, check the serial connection of the PV array and ensure that the open circuit voltage of the PV string does not exceed the maximum operating voltage of the inverter.
How to resolve Grid Underfrequency issues with a Goodwe ES Inverter?
A Grid Underfrequency error on your Goodwe Inverter signifies a utility grid exception where the actual grid frequency is lower than the requirement of the local grid standard. If the problem occurs occasionally, the utility grid may be temporarily abnormal, and the inverter will recover automatically after the grid returns to normal. If the problem occurs frequently, check whether the grid frequency is within the permissible range and contact the local power company if it is not. You can also modify the underfrequency protection threshold or disable the underfrequency protection function after obtaining consent from the local power company, or close the "Grid Underfrequency" function.
What to do about Grid Overfrequency on my Goodwe Inverter?
A Grid Overfrequency error on your Goodwe Inverter indicates a utility grid exception where the actual grid frequency exceeds the requirement of the local grid standard. If this occurs occasionally, the utility grid may be temporarily abnormal, and the inverter should recover automatically once the grid returns to normal. However, if the problem occurs frequently, check whether the grid frequency is within the permissible range and contact the local power company if it exceeds the limit. If the grid frequency is within range, you can modify the overfrequency protection threshold or disable the overfrequency protection function after obtaining consent from the local power company.
What causes Grid Overvoltage on a Goodwe Inverter and how to fix it?
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.
How to fix 'Low Insulation Res.' error on my Goodwe ES Inverter?
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.
