4.2. Grounding Connection (PE)
Connect the inverter to the grounding electrode using ground cable
SOFAR 3.3~12KTLX-G3 is a transformerless inverter which requires
the positive pole and negative pole of the PV array are NOT
grounded. Otherwise, it will cause inverter failure. In the PV
system, all non-current-carrying metal parts (such as mounting
frame, combiner box enclosure, etc.) should be connected to
earthed.
Note
Preparation: prepare the grounding cable (recommend greater than
2.5mm²yellow-green outdoor cable)
Procedure:
Step 1: Remove the insulation layer with an appropriate length using a wire
stripper shown as figure 4-2
