What to do if my Sofar 2200TL Inverter shows a GridOVP error frequently?
- B
  Brenda BakerAug 18, 2025
  If the Sofar Inverter's grid voltage or frequency is frequently abnormal, verify that the grid voltage and frequency are within the acceptable range. If not, contact technical support. If they are within range, inspect the AC circuit breaker and AC wiring. If the grid voltage/frequency is within the acceptable range and 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. However, if the alarm occurs occasionally, it might be due to occasional abnormalities in the electric grid. The inverter should automatically return to normal when the grid stabilizes.

What to do if my Sofar 2200TL displays a GFCIFault error?
- T
  Timothy RossAug 20, 2025
  If the GFCIFault occurs occasionally on your Sofar Inverter, it may be due to temporary external circuit issues. The inverter should automatically return to normal once the fault is resolved. However, if the fault occurs frequently and persists, check the insulation resistance between the PV array and earth (ground) to ensure it is not too low. Also, inspect the insulation conditions of the PV cable.

Why does my Sofar 2200TL show a BusUVP error?
- S
  Sabrina BrayAug 23, 2025
  If your Sofar Inverter displays a BusUVP error, and the PV array configuration is correct, it is possible that the solar irradiance is too low. The inverter should automatically return to normal operation once the solar irradiance increases to a normal level.

What to do if my Sofar 2200TL Inverter displays a PVOVP error?
- H
  Howard MendozaAug 26, 2025
  If your Sofar Inverter shows a PVOVP error, check if 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. If this is the case, adjust the number of series-connected PV modules to decrease the voltage of the PV string to fit within the inverter's input voltage range. The inverter should automatically return to normal operation after these adjustments.

What to do if my Sofar 2200TL displays a PVUVP error?
- R
  Richard GarciaAug 28, 2025
  If your Sofar Inverter displays a PVUVP error, check if too few PV modules are connected in series in a PV string, causing the voltage (Vmp) of the PV string to be lower than the inverter's minimum operating voltage. If this is the case, adjust the number of series-connected PV modules to increase the voltage of the PV string to fit the inverter's input voltage range. The inverter should automatically return to normal operation after these adjustments.

How to fix OverTempFault_Inv error on Sofar 2200TL?
- A
  Amber SalinasAug 30, 2025
  If your Sofar Inverter shows a OverTempFault_Inv error, ensure that the installation position and method meet the requirements. Check if the ambient temperature at the installation position exceeds the upper limit. If it does, improve ventilation to lower the temperature.

How to resolve OverTempDerating error on Sofar 2200TL Inverter?
- F
  foxericSep 2, 2025
  If your Sofar Inverter shows a OverTempDerating error, ensure the installation position and installation method meet the requirements. Check whether the ambient temperature of the installation position exceeds the upper limit. If yes, improve ventilation to decrease the temperature.

What should I do if my Sofar 2200TL shows a BusOVP error?
- O
  Omar DanielSep 4, 2025
  If your Sofar Inverter displays a BusOVP error, turn OFF the “DC switch”, wait for 5 minutes, then turn ON the “DC switch”. Check whether the fault is rectified. If not, contact technical support.

What to do if my Sofar Inverter shows a DciOCP error?
- J
  Joan ChavezSep 7, 2025
  If your Sofar Inverter displays a DciOCP error, check the input mode setting (parallel mode/independent mode). If it’s incorrect, change it. If the input mode is correct, 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.
