What to do if Sofar solar HYD 6KTL-3PH shows Grid OVP?
- J
  Jacqueline BanksAug 23, 2025
  If the Grid OVP alarm occurs occasionally, the inverter will automatically return to normal operation when the electric grid returns to normal. However, if the alarm occurs frequently, verify that the grid voltage/frequency is within the acceptable range. If it is, 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, but the alarm persists, contact technical support to adjust the grid over-voltage, under-voltage, over-frequency, and under-frequency protection points after getting approval from the local electrical grid operator. The possible cause is that the electric grid is abnormal occasionally.

What causes PVOVP error on Sofar solar Inverter and how to fix it?
- A
  Abigail CastilloAug 31, 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.

What to do if my Sofar solar Inverter shows GridOVP frequently?
- J
  Joshua Acosta Jr.Aug 31, 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 to do if Sofar solar HYD 6KTL-3PH displays ConfigError?
- E
  Elizabeth NguyenAug 30, 2025
  If your Sofar solar inverter displays a ConfigError, check the input mode settings (parallel/independent mode) for the inverter. If the settings are incorrect, change the input mode accordingly.

What to do if Sofar solar HYD 6KTL-3PH Inverter displays BMS OVP error?
- C
  Courtney FlowersAug 27, 2025
  If your Sofar solar inverter shows a BMS OVP error, close the inverter and lithium battery, wait 5 minutes, and then reopen both. Check if the problem is resolved. If the issue persists, it may indicate an internal failure of the lithium battery, and you should contact technical support.

Why Sofar solar Inverter shows OverTempDerating?
- W
  William AndradeAug 27, 2025
  The OverTempDerating error on your Sofar solar inverter indicates it's overheating. To resolve this, 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 temperature limit.

What to do if Sofar solar HYD 6KTL-3PH Inverter displays TempFault_Bat error?
- E
  Elizabeth KingAug 26, 2025
  If your Sofar solar inverter displays a TempFault_Bat error, ensure that the battery NTC cable is properly connected for Inner BMS battery. Also, make sure the inverter is installed where there is no direct sunlight, in a cool and well-ventilated place. Ensure the inverter is installed vertically and the ambient temperature is below the inverter temperature limit.

What to do if Sofar solar HYD 6KTL-3PH displays GFCI error?
- T
  Tara OrtizAug 25, 2025
  If your Sofar solar inverter displays a GFCI error, switch OFF the inverter, wait for 5 minutes, and then switch it ON again to see if the problem is resolved. If the error persists, it may indicate internal faults of the inverter, and you should contact technical support for further assistance.
