What to do if my Sofar Inverter shows a GridOVP error?
- A
  April DicksonAug 20, 2025
  If the Sofar Inverter alarm occurs occasionally, it might be due to temporary electric grid issues; the inverter should return to normal when the grid stabilizes. If the alarm is frequent, verify that the grid voltage/frequency is within the acceptable range. If it is, 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, and the alarm persists, contact technical support to adjust the over-voltage, under-voltage, over-frequency, and under-frequency protection settings after approval from your local electrical grid operator. The root cause is that the grid voltage is too high.

  Paul SmithAug 21, 2025
  To resolve the OverTempDerating error on your Sofar Inverter, ensure it's installed away from direct sunlight and in a cool, well-ventilated area. Also, verify that the inverter is mounted vertically and that the ambient temperature remains below the inverter's temperature limit. This error occurs because the internal temperature is too high.

  sarajacksonAug 25, 2025
  If the OVRT alarm on your Sofar Inverter appears occasionally, it may be due to temporary electric grid abnormalities; the inverter should automatically resume normal operation when the grid returns to its normal state. If the alarm occurs frequently, check that the grid voltage/frequency is within the acceptable range. If it is, inspect the AC circuit breaker and AC wiring of the inverter. The root cause of this problem is a faulty OVRT function.
