Grounding connects electrical components to Earth at zero voltage potential. All PV equipment must be. 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 metallic parts to provide. Proper frame grounding requires connecting the grounding holes of the module frame directly to the mounting structure to ensure stable electrical conductivity. Grounding a solar photovoltaic (PV) system involves establishing a low-resistance conductive pathway that connects the non-current-carrying metal components of the array to the earth. Verify the continuity of the grounding system.
