What to do if my Sofar 2200TL Inverter shows a GridOVP error frequently?

If the Sofar Inverter's grid voltage or frequency is frequently abnormal, verify that the grid voltage and frequency are within the acceptable range. If not, contact technical support. If they are within range, inspect the AC circuit breaker and AC wiring. If the grid voltage/frequency is within the acceptable range and AC wiring is correct, but the alarm persists, contact technical support to adjust the grid over-voltage, under-voltage, over-frequency, and under-frequency protection points after getting approval from the local electrical grid operator. However, if the alarm occurs occasionally, it might be due to occasional abnormalities in the electric grid. The inverter should automatically return to normal when the grid stabilizes.
