    Why does my Sofar solar HYD 3000-EP show GridOVP?
    • B
      brightaliciaAug 12, 2025
      The GridOVP alarm indicates that the electric grid voltage or frequency is outside the acceptable range. This can happen occasionally due to grid abnormalities, in which case the inverter will automatically return to normal when the grid stabilizes. However, if the alarm occurs repeatedly, and your AC wiring is correct, contact technical support to adjust the grid protection settings after getting approval from your local electrical grid operator.
