    Why does my Sofar HYD 5KTL-3PH Inverter show a GridOVP error?
    • R
      Rhonda PatrickAug 16, 2025
      If the Sofar Inverter shows a GridOVP error occasionally, it might be due to temporary grid abnormalities. The inverter should automatically resume normal operation once the grid stabilizes. However, if the GridOVP alarm occurs frequently, verify that the grid voltage and frequency are within the specified range. Also, check 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 over-voltage and under-voltage protection settings after getting approval from your local electrical grid operator.

    How to fix Sofar Inverter OverTempDerating error?
    • J
      Jessica HesterAug 19, 2025
      If your Sofar Inverter displays an OverTempDerating error, it means the inverter's temperature is too high, causing it to reduce its output. Ensure the inverter is installed in a cool, well-ventilated area, away from direct sunlight. Also, verify that the inverter is mounted vertically and that the ambient temperature is below the inverter's maximum temperature limit.

    What to do if Sofar Inverter shows BMS OVP error?
    • R
      Ryan StanleyAug 22, 2025
      If your Sofar Inverter displays a BMS OVP error, it indicates an overvoltage alarm from the connected lithium battery. To resolve this, switch off both the inverter and the lithium battery. Wait for 5 minutes, and then switch them back on. If the error continues, contact technical support for further assistance.

    How to troubleshoot a TempErrBat error on a Sofar HYD 5KTL-3PH?
    • G
      Gregory HoustonAug 26, 2025
      If your Sofar Inverter is showing a TempErrBat error, and you are using an Inner BMS battery, check that the battery NTC cable is properly connected. Ensure that the inverter is installed in a location without direct sunlight, is well-ventilated, and maintains an ambient temperature below the inverter's temperature limit. The inverter should also be mounted vertically.
