    What to do if Sofarsolar SOFAR 1600TL-G3 Inverter shows power grid voltage too high?

      If the alarm occurs occasionally, the issue might be temporary grid fluctuations; the inverter should return to normal when the grid stabilizes. However, if this happens frequently, verify that your grid voltage and frequency are within the acceptable range. If they are not, contact technical support. If the voltage and frequency are normal, inspect the AC circuit breaker and AC wiring. If problems persist despite correct voltage/frequency and wiring, contact technical support to adjust the inverter's protection settings after getting approval from your local grid operator.

    What to do if Sofarsolar SOFAR 1600TL-G3 Inverter shows GFCI fault?
    • C
      Christopher JohnstonAug 20, 2025
      If the GFCI fault occurs occasionally, it might be due to temporary external circuit abnormalities, and the inverter should automatically return to normal once the issue is resolved. However, if the fault occurs frequently and lasts a long time, check the insulation resistance between the PV array and earth (ground) to ensure it is not too low. Also, inspect the insulation of the PV cables.

    Why is my Sofarsolar SOFAR 1600TL-G3 temp too high?
    • L
      Lisa HaasAug 23, 2025
      The inverter temperature might be too high because the ambient temperature of its installation location exceeds the upper limit. To resolve this, improve ventilation around the inverter to decrease the temperature.

    What to do if Sofarsolar SOFAR 1600TL-G3 showing input voltage too high?

      The input voltage might be too high because too many PV modules are connected in series in a PV string, causing the voltage (Voc) of the PV string to exceed the inverter's maximum input voltage. To fix this, adjust the number of PV modules connected in series to decrease the voltage of the PV string, ensuring it fits within the inverter's input voltage range. The inverter should automatically return to normal operation after these adjustments.

    Why Sofarsolar Inverter showing input voltage too low?
    • D
      Dr. Stephen LopezAug 27, 2025
      The input voltage might be too low because too few PV modules are connected in series in a PV string. This results in the voltage (Vmp) of the PV string being lower than the inverter's minimum operating voltage. To resolve this, adjust the number of series-connected PV modules to increase the voltage of the PV string, ensuring it fits within the inverter's input voltage range. The inverter will automatically return to normal operation after the correct adjustments.

    What to do if Sofarsolar SOFAR 1600TL-G3 grid current is too high and hardware protection activated?
    • J
      Jacob BradfordAug 30, 2025
      ID15-ID24 indicate internal faults within the inverter. Turn OFF the DC switch, wait for 5 minutes, and then turn it back ON. Check if the fault is rectified. If the issue persists, contact technical support.

    Why Sofarsolar Inverter derated because of high temperature?
    • C
      Charles HawkinsSep 2, 2025
      The inverter may have derated because the ambient temperature of its installation position exceeds the upper limit. To solve this, improve ventilation to decrease the temperature around the inverter.

      Check if the input current exceeds the maximum input current of the inverter. Also, verify the input wiring. If both are correct and the issue persists, contact technical support.

    Why Sofarsolar SOFAR 1600TL-G3 bus voltage is too low?
    • D
      Donna CabreraSep 7, 2025
      If the PV array configuration is correct (no ID05 fault), the bus voltage might be too low because the solar irradiance is insufficient. The inverter should automatically return to normal operation once the solar irradiance returns to a normal level.

      Brenda DavisSep 9, 2025
      Check the input mode setting (parallel mode/independent mode) of the inverter. If it’s incorrect, change it according to the manual.
