What to do if Sofar HYD3000-ES shows power grid voltage too high?

If the alarm occurs occasionally, the electric grid may be temporarily abnormal. The Sofar Inverter should automatically return to normal when the grid stabilizes. If the alarm happens frequently, verify the grid voltage and frequency are within the acceptable range. If they are not, contact SOFAR technical support. If they are within range, inspect the AC circuit breaker and AC wiring of the HYD-ES inverter. If the grid voltage/frequency is within the acceptable range and AC wiring is correct, while the alarm occurs repeatedly, contact SOFAR technical support to change the grid over-voltage, under-voltage, over-frequency, under-frequency protection points after obtaining approval from the local electrical grid operator. If you confirm that AC wiring is correct & grid voltage/frequency is ...
