Does my grounding 'plan' seem appropriate?
I am installing a new solar setup at an off-grid cabin in Northern Arizona. Lightning is a real concern in our area. My array will be a ground mount using Ironridge components and will be about 50 feet from the cabin. My plan is to sink four grounding rods basically at each corner of the array. I would tie each of these to the bare 6 ga. copper grounding wire coming off of the array (I'm guessing at the combiner box at the ground busbar). The 6 ga. bare wire would then continue, buried outside of the conduit but in the same trench, all the way to the cabin. At the cabin, the ground wire would go to the ground of the Outback equipment as well as the negative side of the battery bank and the existing ground rod for the cabin itself. Does this sound correct? I greatly appreciate any guidance here.
