Grounding
The connection point for the AC grounding conductor (also known as PE –
protective earth) is a copper grounding bar with several 12 mm bolts located in
the AC interface enclosure and marked with PE. The ground conductor size
depends on the size of the main circuit breaker. Refer to local applicable
electrical installation codes for grounding requirements for your system.
Grounding terminals for PV array frames are provided in the DC interface
enclosure.
