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.

Photovoltaic bracket grounding flat iron installati ounting in compliance with the included instru tions. The system is a non-separately der ing in the array. Connect arrays to equipment gr und. Properly grounding solar PV systems is one of the most critical aspects of a safe and reliable installation, governed by Part V of NEC Article 690. Warranty details are available on website. All installers must thoroughly read this manual and have a clear understanding of the installation procedures prior to installation. If yes, do I ground it by driving a grounding rod into the ground beside the array and running a bare copper wire from one panel down to the rod in the ground? Do I need to connect all panels using the bare copper wire? Or, do I not ground at all, and run the ground in the trench with the PV wires. Grounding (also known as earthing) is the process of physically connecting the metallic and exposed parts of a device to the earth. It is a mandatory practice required by NEC and IEC codes to protect both equipment and personnel from damage and electric shock hazards. Why? Because unlike sloped surfaces, flat terrain lets you play by your own rule.
