After watching several of Mike Holt's YouTube videos about not adding another Ground Rod for a new PV installation, I was surprised that my Local Inspector requires that I add a 2nd Ground Rod for my Ground Mount PV Array. He wants me to run a wire from the new Ground Rod to the Ground Bar inside the DC Disconnect Box located on the PV Array. I already have an EGC, Equipment Ground Conductor, wired from the Main Load Center to the Inverter's "AC Ground" terminal and then another wire from the Inverter's "DC Ground" terminal to the Ground bar inside the DC Disconnect at the PV Array.
Here is the current grounding path ...
<Well> <GEC bare wire> <Gnd Bar Main Load Center> <EGC wire> <AC Gnd Inverter DC Gnd> <Gnd Bar DC Disconnect> <Solar Panels & Frame>
The above does not show the new Ground Rod nor its connection to the DC Disconnect.
Should I trench 90' from the new Ground Rod to the original Well Casing (AC GROUND) and bond the two grounds together?
Is 6 AWG solid OK ?
