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
