What to do if Sofar solar Inverter shows GridOVP alarm frequently?
- M
  Michelle HillAug 20, 2025
  If the GridOVP alarm occurs occasionally, it could be due to temporary electric grid abnormalities. The inverter should automatically return to normal once the grid stabilizes. However, if the alarm is frequent, verify that the grid voltage and frequency are within the acceptable range. If they are, inspect the AC circuit breaker and AC wiring of the inverter. If the grid voltage/frequency is outside the acceptable range and the AC wiring is correct, contact technical support to adjust the grid over-voltage, under-voltage, over-frequency, and under-frequency protection points, but only after getting approval from your local electrical grid operator.

  Susan LewisSep 3, 2025
  If the Sofar solar Inverter alarm 'GridOVP' occurs occasionally, it might be due to an abnormal electric grid. The inverter should automatically return to normal when the grid stabilizes. If the alarm happens frequently, verify that the grid voltage and frequency are within the acceptable range. If they are, inspect the AC circuit breaker and AC wiring of the inverter. If the grid voltage/frequency is not within range and the wiring is correct, and the alarm persists, contact technical support to adjust the grid over-voltage, under-voltage, over-frequency, and under-frequency protection points, but only after getting approval from your local electrical grid operator.
