A grounding wire should come from this whole setup down to your indoor equipment. Being installed on a dwelling, you are required to have ground fault protection (GFP). So you should have a ground fault protector like the Midnite Solar MNDC-GFP63 between the panels and the charge controller.
Grounding solar panels is necessary because: It reduces built up charge, making your system less attractive to lightning. If a charge builds or lightning hits, the discharge will go into the earth instead of your cable. Without grounding this will not happen. Grounding minimizes power shock from high voltage components. The NEC requires grounding.
Key points from the NEC: The code requires all non-current-carrying metal parts of the solar PV system to be grounded. It specifies the minimum size of grounding conductors (more on this later). The NEC also outlines requirements for grounding electrodes (like ground rods) and how they should be installed.
Your local electric utility company or a qualified electrician can provide you with more information about solar panel grounding. Now that you know how to install, maintain, and troubleshoot ground solar panels, you can start saving money on your energy bills.
Nothing is currently grounded. Even the solar panels are isolated with VHB tape. The charge controller, inverter battery and busbars are in a wood box. For code reasons, I am in Tampa Florida. Off Grid, Off Grid. Not even sometimes. the panels need to be bonded to a ground, which needs to be a separate ground form the house.
Following this, you should connect a grounding wire to the grounding rod. The wire should be made of copper or galvanized steel and should be at least 8 feet long. Use a wrench to tighten the connection between the wire and the rod. In the third step, run the grounding wire from the rod to your solar panel array.
From what I''ve read the general consensus for 12V DC off-grid systems seems to be that you should run a ground wire from components such as the Inverter and MPPT Charge Controller to the DC negative bus bar, and …
