The recommended approach is to use a separate DC grounding electrodefor PV arrays and frames,as this enhances protection against lightning and transient voltage. For lightning protection associated with grounding systems,refer to NFPA 780 and NEC 250.

This process involves two distinct but related concepts: system grounding, which provides a reference to earth for the electrical system (stabilizing voltages and assisting in clearing certain faults), and equipment grounding, which bonds all normally non-current-carrying.

The chassis must be grounded through the equipment grounding conductor. The key rule involves the neutral-to-ground bond: Only one bond point avoids parallel paths and GFCI issues.
