Connect the inverter to the grounding electrode using ground cable.
SOFAR 75-136kW 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 16mm² yellow-green
outdoor cable and M8 OT Terminal)
Procedure:
Step 1
: Remove the insulation layer with an appropriate length using a wire stripper
shown as figure 5-2.
