To Next PageTo Next PageWhat to do if my Sofar solar 80KTL Inverter shows a GFCIFault?
If the GFCIFault occurs occasionally, it might be due to abnormal external circuits. The inverter should automatically return to normal once the issue is resolved. If the fault happens frequently and persists, inspect the insulation resistance between the PV array and the ground. Also, check the insulation of the PV cable.
What to do if my Sofar solar 80KTL Inverter displays a GridOFP alarm frequently?
If the GridOFP alarm occurs frequently, verify that the grid voltage and frequency are within the acceptable range. If they are not, contact technical support. If they are within range, check the AC circuit breaker and AC wiring of the inverter. If the grid voltage/frequency is within the acceptable range and AC wiring is correct, while the alarm occurs repeatedly, contact technical support to change the grid over-voltage, under-voltage, over frequency, under-frequency protection points after obtaining approval from the local electrical grid operator.
Why does my Sofar solar 80KTL show a TempFault_HeatSink1 error?
The TempFault_HeatSink1 error on your Sofar solar Inverter indicates that the ambient temperature around the installation area is too high. To resolve this, improve ventilation to lower the temperature.
What does GridOVP mean on my Sofar solar 80KTL Inverter?
If your Sofar solar Inverter is showing a GridOVP alarm occasionally, it means the electric grid is experiencing occasional abnormalities. The inverter should automatically return to normal operation.
What should I do if my Sofar solar Inverter displays a HwADFaultIGrid error?
Turn OFF the “DC switch”, wait for 5 minutes, then turn ON the “DC switch”. Check whether the fault is rectified. If not, please contact technical support.
