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 HYD 15KTL-3PH 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 15KTL-3PH shows a BMS communication failure of lithium battery?
