Grounding is a critical safety practice in photovoltaic (PV) systems, and according to the National Electrical Code (NEC), all equipment in a photovoltaic system should indeed be grounded. This grounding serves multiple purposes, such as preventing electrical shock hazards, minimizing the risk of equipment damage from electrical surges, and maintaining system performance. Grounding helps ensure that any fault currents have a safe path to ground, which is essential for both personnel safety and the proper functioning of overcurrent protective devices.

In the context of a PV system, grounding not only applies to the modules and mounting structures but also to inverters, transformers, and associated wiring. Proper grounding helps in the reliable operation of the system, complies with electrical codes, and enhances the overall safety features required for installations. Thus, the assertion that all equipment in a photovoltaic system should be grounded aligns with NEC guidelines.
