What to do if my Sofar solar Inverter is force shutdown?
If your Sofar solar Inverter is remotely controlled and undergoing a forced shutdown, but you are not controlling it, disconnect the DC switch of the inverter. Wait five minutes, then turn the DC switch back on. After the inverter restarts, check if the problem is resolved. If not, contact SOFARSOLAR customer service.
What to do if my Sofar solar 3.3~12KTLX-G3 Inverter shows GridUVP error?
If your Sofar solar Inverter displays the GridUVP alarm frequently, first verify that the 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 of the inverter.
How to fix OverTemp Derating error on Sofar solar Inverter?
If your Sofar solar Inverter shows OverTemp Derating, make sure the installation location and method comply with the user manual's requirements. Check if the ambient temperature exceeds the upper limit; if so, improve ventilation. Also, check for dust or foreign objects blocking the fan at the air inlet, and clean the inverter every half a year to improve ventilation and heat dissipation.
What to do if my Sofar solar Inverter has GFCIFault?
If your Sofar solar Inverter displays a GFCIFault, and it occurs occasionally, it might be due to temporary abnormalities in external circuits. The inverter should automatically return to normal operation once the fault is corrected. If the fault happens frequently and persists, check the insulation resistance between the PV array and earth (ground) and inspect the insulation condition of the PV cable.
Why does my Sofar solar 3.3~12KTLX-G3 show GridOVP error?
If your Sofar solar Inverter is showing a GridOVP alarm occasionally, it's likely due to occasional abnormalities in the electric grid. The inverter should automatically return to normal operation when the electric grid returns to its normal state.
How to solve RelayFail error on Sofar solar 3.3~12KTLX-G3 Inverter?
To address the RelayFail error on your Sofar solar Inverter, check if the resistance to ground of the PV string is too low, and inspect the PV cable for any insulation damage. If this does not solve the issue, contact the new energy customer service of Capital Airlines.
What to do if my Sofar solar 3.3~12KTLX-G3 Inverter displays GridOFP error?
If your Sofar solar Inverter displays the GridOFP alarm repeatedly, and the grid voltage/frequency is within the correct range while the AC wiring is properly connected, contact technical support. You may need to change the grid over-voltage, under-voltage, over-frequency, and under-frequency protection points after getting approval from the local electrical grid operator.
How to troubleshoot FanFault1 on Sofar solar 3.3~12KTLX-G3 Inverter?
If your Sofar solar Inverter displays a FanFault1 error, check for dust or foreign objects blocking the fan at the air inlet. If found, improve the ventilation and heat dissipation of the environment. It's recommended to clean the inverter every six months.
What to do if my Sofar solar 3.3~12KTLX-G3 displays OVRT error?
If your Sofar solar Inverter shows an OVRT error, turn OFF the “DC switch”, wait for 5 minutes, then turn ON the “DC switch” again. Check if this resolves the fault. If not, contact technical support.
How to fix GFCIDeviceFault(DC) error on Sofar solar Inverter?
If your Sofar solar Inverter displays a GFCIDeviceFault(DC) error, turn OFF the “DC switch”, wait for 5 minutes, then turn ON the “DC switch” again. Check if this resolves the fault. If not, contact technical support.
