What to do if my Sofar solar Inverter shows GridOVP frequently?
- J
  Julia CervantesAug 16, 2025
  If the GridOVP alarm occurs frequently on your Sofar solar inverter, first check if the grid voltage or frequency is within the acceptable range. If the voltage or frequency is not within the acceptable range and the AC wiring is correct, contact technical support to change the grid over-voltage, under-voltage, over-frequency, and under-frequency protection points after getting approval from the local electrical grid operator. However, if the alarm occurs occasionally, the inverter should automatically return to normal when the electric grid returns to normal.

What causes PVOVP error on Sofar solar Inverter and how to fix it?
- D
  Danielle HarrisonAug 19, 2025
  The PVOVP error on your Sofar solar inverter indicates that the PV series voltage (Voc) is higher than the maximum input voltage of the inverter. To resolve this, check whether the PV series voltage is indeed too high. If it is, adjust the number of PV modules in series to reduce the PV series voltage, ensuring it fits within the input voltage range of the inverter. After making this correction, the inverter should automatically return to its normal state.
