 Good grounding for the SUN2000 can help resist the impact of the surge voltage and improve the
EMI performance. First connect the PGND cable before connecting the AC power cable, DC power
cable, and communication cable.
For the system with one SUN2000, connect the PGND cable to the ground. For the system with
multiple SUN2000s, connect the PGND cables of all SUN2000s to a ground bar in equipotential
mode.

If the installation location is near the ground, first connect the PGND cable to the ground before
installing the SUN2000 on the wall.
