Why does my Sofar solar HYD 10K-20KTL-3PH show a GridOVP error?
- D
  Denise CrawfordAug 2, 2025
  If the Sofar solar Inverter displays a GridOVP alarm occasionally, it might be due to temporary electric grid issues. The inverter should automatically resume normal operation once the grid stabilizes. However, if the alarm appears frequently, verify that the grid voltage and frequency are within the acceptable range. If they are, inspect the AC circuit breaker and the inverter's AC wiring. If the grid voltage or frequency is consistently outside the acceptable 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 settings after approval from your local electrical grid operator.
