pump controllers have built-in surge protectors that help to protect them if the controller’s
ground terminal is connected to an effective ground path. Bond the structural components and
electrical enclosures. Interconnect the PV array frames, the mounting rack, and the ground terminals
of all electrical devices, and run the wire to an earth connection. See Figure 5-4 Grounding Diagram.
