2.3.a Grounding

♦A single point ground connection is located in the lower right hand side of the StarInverter cabinet. The PV panel grounding wire is terminated there. The AC ground connection is terminated next to the Line and Line 2/Neutral connections on the circuit board. The PV ground is bolted to the cabinet with a ¼-20 bolt. (Refer to Figure 7.)

♦Figure 6 includes schematic representations of the PVP1800, and PVP2800 single point grounding. The front cover is grounded through the two cover mounting screws.
