Connection from the controller directly to the battery is always better. You will be giving up charge current because of voltage drop in the wiring unless the owner rewired the trailer to use thicker battery cables from the controller to the distribution and back to the battery. You will get some charging, it just won't be optimal.
If it was my trailer, installing bigger cables from the controller to the battery would be one of the first mods I'd do. With what you have for modules and batteries, that is going to be a nice boondocking system.
Thats kinda what I was thinking. I called the previous owner. He told me that when he installed the system, he was told it was fine to just connect up to the fridge,and not run all the way to the batteries on the tongue. In my head, Im thinking that it HAS to be better to go straight to the battery, and not just connected into the system.
If I were to run wire from the controller to the battery, what gauge should it be? I would think it would take about 20-25 feet of wire. Maybe 4 or 6 gauge?
And is it just a direct connection the the pos and neg of the battery?? Im thinkkng I might upgrade the controller to a MPPT charge controller to maximize charging and use.
