[RE-wrenches] Off-grid array far, far from the batteries

[jay]

Hi Chris,


If you run all 6 in series 
that puts you about 2.6% vd with #4 wire
about 200vdc vmp and 10 amps.  

In cold enough weather you’re probably above the FM-100 so would put you in a 600vdc controller.

I’d go with 600v controller vs doing AC coupling.

More efficient and the more volt you go the smaller the wire.

My 2 cents

He has six more of the same modules…but the ideal site for solar is 900 feet away from his batteries and the rest of the system.  Yeah, good planning, right?
