Hello all,
I am located in northern Maine. I will be doing a grid tie system and ground mounting. I currently have 60 Hyundai 305W Poly HIS-M305 72 cell panels. I have not purchased anything else as of yet. The Sunny boy site has recommended two SB 6.0-1SP-US-40 - 240V and one SB 5.0-1SP-US-40 - 240V. Does this sound like a good inverter plan?
Any recommendations for a disconnect box?
I am also not grasping the wire gauge/type I need to use. My farthest panel will be about 200+- feet from the inverter.
I am planning a home made racking system. I need to dig down about 6 ft (through ledge) to get below the frost so I am in nightmare territory for this part of the project(ugh).
Anything else I need to be thinking about/purchasing?
Thanks!
