What to do if Sofar solar 3K-6KTLM-G3 Inverter shows GridOVP alarm frequently?
- A
  Alyssa LewisAug 5, 2025
  If the GridOVP alarm occurs occasionally, it could be due to temporary electric grid abnormalities. The inverter should automatically return to normal once the grid stabilizes. However, if the alarm is frequent, verify that the grid voltage and frequency are within the acceptable range. If they are, 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, contact technical support to adjust the grid over-voltage, under-voltage, over-frequency, and under-frequency protection points, but only after getting approval from your local electrical grid operator.
