SOFAR 25~50KTLX-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
16mm²yellow-green outdoor cable, refer to section 4.3)
Procedure:
Step 1: Remove the insulation layer with an appropriate length using a wire
stripper shown as figure 4-2
