- KkingamyAug 13, 2025
To resolve FreqDerating on your Sofarsolar Inverter, ensure that the grid frequency and voltage are within the acceptable range.
How to fix FreqDerating on my Sofarsolar Inverter?
To resolve FreqDerating on your Sofarsolar Inverter, ensure that the grid frequency and voltage are within the acceptable range.
How to resolve PvConfigError on Sofarsolar Inverter?
To resolve a PvConfigError on your Sofarsolar Inverter, check the PV input mode settings (parallel/independent mode). If the settings are incorrect, change the PV input mode accordingly.
Why does my Sofarsolar Inverter show a GridOVP error?
If the GridOVP alarm occurs occasionally on your Sofarsolar Inverter, it might be due to temporary electric grid issues. The inverter should automatically return to normal operation once the grid stabilizes. However, if the alarm appears frequently, verify that your 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 over-voltage, under-voltage, over-frequency, and under-frequency protection settings, but only after getting approval from your local electrical grid operator.
What to do if my Sofarsolar HYD KTL-3PH Inverter shows a BMS communication failure of lithium battery?
If you're experiencing a BMS communication failure of the lithium battery with your Sofarsolar Inverter, first ensure that your battery is compatible with the inverter, CAN communication is recommended. Then, check the communication line and port between the battery and the inverter for any faults.
How to prevent OverTempDerating on my Sofarsolar HYD KTL-3PH Inverter?
To resolve OverTempDerating on your Sofarsolar Inverter, make sure the unit is installed away from direct sunlight.
What to do if my Sofarsolar HYD KTL-3PH Inverter displays TempFault_Bat?
To address a TempFault_Bat error on your Sofarsolar Inverter, ensure it is installed away from direct sunlight in a cool, well-ventilated area. Also, confirm that the inverter is mounted vertically and the ambient temperature remains below the inverter's temperature limit.
What to do if my Sofarsolar HYD KTL-3PH displays a GFCI error?
If your Sofarsolar Inverter is showing a GFCI error, it may indicate internal faults. Try switching the inverter OFF, waiting for 5 minutes, and then switching it back ON to see if the problem resolves. If not, contact technical support.
What to do if my Sofarsolar HYD KTL-3PH shows FanFault1?
To troubleshoot FanFault1 on your Sofarsolar Inverter, check whether fan 1 is running normally.
