What causes Reserved (ID113) error on Sofar solar KTLX-G3 Inverter?
Check if the ambient temperature of the installation position exceeds the upper limit. If it does, improve ventilation to decrease the temperature. Also, check whether the inverter has dust and whether there are foreign matters blocking the fan at the air inlet.
What causes CT Disconnect error on Sofar solar KTLX-G3 Inverter?
Check the wiring of input, output and communication according to the user's manual. If the use method is not ruled out, please contact the new energy customer service of Capital Airlines.
What to do if Sofar solar KTLX-G3 Inverter GridUVP alarm occurs frequently?
If the GridUVP alarm occurs frequently, first check if the grid voltage/frequency is within the acceptable range. If it is not, contact technical support. If the voltage/frequency is ok, check the AC circuit breaker and AC wiring of the inverter.
Why does my Sofar solar KTLX-G3 Inverter show GridOVP?
If the GridOVP alarm occurs occasionally, it is likely due to occasional abnormalities in the electric grid. The inverter will automatically return to normal operation when the electric grid stabilizes.
What to do if Sofar solar Inverter shows GridOFP repeatedly?
If the grid voltage/frequency is within the acceptable range and AC wiring is correct, while the GridOFP 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.
How to fix FanFault1 on Sofar solar KTLX-G3 Inverter?
Check the inverter for dust and foreign objects blocking the fan at the air inlet. If found, improve the ventilation and heat dissipation of the environment.
What to do if Sofar solar KTLX-G3 Inverter displays OVRT?
If your Sofar solar Inverter displays OVRT, 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 Sofar solar Inverter displays unrecoverH wAcOCP?
If your Sofar solar Inverter displays unrecoverH wAcOCP, 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.
Why does my Sofar solar Inverter show BusUVP?
If the configuration of the PV array is correct, the BusUVP error could be because the sun irradiation is too low. Once sun irradiation returns to normal, the inverter will work normally again.
