I am grounding my off grid solar system & want to ensure it passes state inspection. My plan after reviewing a lot of threads and reading various code articles is to ground my solar panels at the array with a 6awg copper wire to a grounding rod. Then I would ground my PV combiner box near the array with a 6awg copper wire to the ground bus bar in my solar shed about 20ft away. The charge controller and inverter would also connect to the ground bus bar, which would connect to my AC service panel. The AC service panel would connect to a ground rod right behind my solar shed, which is about 30ft away from my solar array. Finally, I would bond the 2 ground rods with another 6awg copper wire.
Please advise if this would work for code purposes (NEC 2020) or if I am missing something and changes are needed. Thank you for any advice, this has been difficult to pin down, especially after receiving conflicting information from different electricians I have contacted.
