4.1. Electrical connection
Figure4-1 Shows the flowchart for connecting cables to the inverter.
4.2. Connecting PGND Cables
Connect the inverter to the grounding electrode using protection ground
(PGND) cables for grounding purpose.
The inverter is transformer-less, requires the positive pole and negative
pole of the PV array are NOT grounded. Otherwise it will cause inverter
failure. In the PV power system, all non current carrying metal parts
(such as: PV module frame, PV rack, combiner box enclosure, inverter
enclosure) should be connected to earth.
