Grounding of solar system
mbu Posts: 7Registered Users ✭✭
Im not sure if this question was ever asked but could not find it on previous threads. I have a 2400 solar panel array on a corrugated roof ie 6 x 24 v250w in 3s2p and 6x 12v150w 6s . the two groups are in the same corrugated roof but in two different locations and each has its own mppt cc.I want to ground the system.my idea is to run a single yellow household earth wire from any part of the metal roof to an earth rod buried just outside the house. i also plan to connect the lead neg terminal of my 48v battery bank to the same earth rod and to also connect the earth of my 5kva invertor to the same earth rod.will this work in terms of lighning diversion and allowing the circuit breaker to trip when there is a shot circuit?
