400W of solar
150V/35amp charge controller
2000W inverter/charger
300ah battery bank
This install is in a 19ft travel trailer
I'm pretty much following the wiring diagram from explorist.life, which can be seen here https://www.explorist.life/?da_image=51400
*EDIT: I plan to wire my panels in 2x "series" groups then these 2 groups in parallel
However, install videos I've watched show folks using 6 gauge wire to connect battery positive to the DC part of the factory breaker box. I know Will Prowse suggests a 6 gauge wire/50-100 amp fuse for this purpose in his book.
One youtube guy ran a 6 gauge wire straight from his battery (after the big fuse between battery and positive bus bar) to the factory positive terminal on the front of the trailer where the old, removed at this point, factory battery connected. I'm not sure what the gauge of the wire from this terminal to the DC breaker box was, but this guy in the video is pretty switched on and I imagine it was adequate.
So my dilemma is do I follow the interactive wiring diagram above (which is essentially for a van) and run positive and negative 2 gauge wire with a 100 amp breaker on positive from my battery bank to the trailer's DC breaker box and just discard the factory wire/wires coming from the terminal at the front of the trailer where the removed factory battery was, or do I run the positive 2 gauge wire with the 100 amp fuse to the positive terminal at the front of the RV where the old battery used to be connected and just ground to chassis from the negative bus bar and assume that the factory wire from the factory battery terminal to the DC breaker box is adequate?
I'm all about overkill for safety. However, I don't think I'm gonna be able to wire a 2 gauge wire into the DC breaker box, as it will probably be too big in physical size. I don't think you can suddenly "size-down" the 2 gauge wire just before it connects to the DC breaker box.
All we will be running off the DC breaker box is the lights, a vent fan, the little fan for the composting toilet, and then whatever gets used by the furnace and the fridge while they run on propane (I understand they both use a small amount of power even when running on propane).
As you can see, I am a total novice. Any advice would be appreciated.
