Do you mind discussing in detail how you grounded your solar panels, equipment, etc in regards to an earth ground? Any thoughts on grounding and how to approach it with a small solar system such as mine. See below
3- 80w 12v pv panels wired in parallel mounted to roof approx 30ft from earth
225 AH battery bank
15a mppt charge controller
1500 watt inverter
AC breaker panel connected to inverter
I used 1 inch self tapping screws and screwed copper lay in Lugs on every panel . I did this on every panel and I used bare awg 6 gauge. From there I sunk a 5/8 ground rod and fastened the 6 gauge to the ground rod with a acorn clamp. I would also recommend grounding your inverter to the rod also. I hope that helps. If you have anymore question feel free to ask.
