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.
Attention
Prerequisites:
The PGND cables are prepared (
≥
4mm
²
outdoor power cables are
recommended for grounding purposes),the color of cable should be
yellow-green.
Procedure:
Step 1
