I'm installing a Sol-Ark 12K system on my off-grid farm and have a question about grounding and bonding. In many videos I have watched, I have noticed that a green 6AWG THNN stranded copper wire is ran inside the conduit along with the PV wires from the array to the place where the hybrid inverter is mounted. Is this wire attached to the grounding rod of the array and to all the neutral lugs in switches and boxes from the array to the Sol-Ark for bonding purposes? What is the purpose for this wire? Is it necessary for an off-grid system?
