Solar controller tie in

[mtnman1000]

I am getting ready to install a couple solar panels on my 28' Keystone Springdale and am trying to determine how to get the charging to to the front mounted 6V batteries. I was thinking of running the MC4 wiring down the fridge vent then to the wardrobe closet where the controller will be. From there my thought is to wire the controller to the 12V input lugs on the fridge. There is about a 23' run from there to the breakers (15 amp) then battery battery but I don't know the AWG of that wire.

Would this work OK? I figure if it's 8 AWG it get a 2.5 % drop. Also if I installed more than 2 100W panels, the breaker to fridge would be too small I think.

Outside of this I'd need to figure out how to get the controller in the front storage then charge cable tray from there to the batteries. That would be a bit out of my league though.

A solar controller needs ventilation. Will the controller receive adequate ventstion in a closet? Further, a solar controller should be mounted as close to the batteries as practical. How close is the closet to the batteries? A two percent drop is all you should tolerate. Six gauge to the batteries is better. You’ve complied with a solar wiring chart?
