What to do if my Sofar Inverter shows a GFCI Fault?
If the GFCI fault on your Sofar Inverter occurs occasionally, it may be due to occasional abnormalities in the external circuits; the inverter should automatically return to normal once the issue is resolved. If the fault occurs frequently and lasts a long time, check the insulation resistance between the PV array and earth (ground) and inspect the insulation of the PV cables.
How to cool down a Sofar 3K-6KTLM-G2 that is too hot?
If your Sofar Inverter temperature is too high, check whether the ambient temperature of its installation location exceeds the upper limit. If it does, improve ventilation to decrease the temperature.
What to do if the input voltage is too high on my Sofar 3K-6KTLM-G2 Inverter?
If the input voltage on your Sofar Inverter is too high, 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 PV modules connected in series to decrease the PV string's voltage to fit within the inverter's input voltage range. The inverter should automatically return to normal after the adjustments.
What to do if the input voltage is too low on my Sofar Inverter?
If the input voltage on your Sofar Inverter is too low, check whether too few PV modules are series connected in a PV string, thus the voltage(Vmp) of the PV string is lower than the minimum operating voltage of inverter. If yes, adjust the number of series connected PV modules to increase the voltage of the PV string to fit the input voltage range of inverter. Inverter automatically returns to normal operating status after correct adjustments.
How to fix low insulation resistance on Sofar Inverter?
Check the insulation resistance between the PV array and earth (ground) on your Sofar Inverter. If a short circuit is present, rectify the fault.
Why is the bus voltage too low on my Sofar Inverter?
If the PV array configuration is correct (no ID05 fault) on your Sofar Inverter, the possible cause is that the solar irradiance is too low. The inverter automatically returns to normal operating status after the solar irradiance returns to normal level.
How to balance input current on Sofar 3K-6KTLM-G2 Inverter?
Check the input mode (parallel mode/ independent mode) setting of Sofar Inverter according to Section 6.3 (C) 6.Input Mode of this user manual. If it’s incorrect, change it according to Section 6.3 (A) 10.Set Input mode of this manual.
What causes hardware protection due to high input current on Sofar Inverter?
Check whether the input current on your Sofar Inverter is higher than the maximum input current of inverters, then check the input wiring, if both are correct, please contact technical support.
Why is my Sofar 3K-6KTLM-G2 Inverter derating due to high temperature?
Ensure the installation position and installation method of your Sofar Inverter meet the requirements of Section 3.4 of this user manual.
What to do if the SD card is faulty on my Sofar Inverter?
Please replace the SD card of your Sofar Inverter.
