What to do if my Huawei SUN2000-50KTL-M0 shows Grid Overvoltage?

If your Huawei Inverter displays a Grid Overvoltage error, it means the grid voltage exceeds the upper threshold. First, check if the grid connection voltage is too high and contact the local power operator if it is. If confirmed and with the power operator's consent, you can modify the overvoltage protection threshold. Ensure the peak grid voltage doesn't exceed the upper threshold.
