The equipment grounding conductor (EGC) from the main panel and PV arrays are connected to the Ground terminal and Ground bus in the inverter. This simple yet critical detail can save you time, money, and headaches down the road. Whether you're a DIY enthusiast or just want to understand the process better, this. . 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. This process involves two distinct but related concepts: system grounding, which connects current-carrying conductors to the earth for voltage. . Here are the steps you need to follow to properly ground your solar panels: Drive a grounding rod into the ground near your solar panel array. The rod should be made of copper or galvanized steel and should be at least 8 feet long. Here are the most common methods: 1.
