I have a small teardrop camper with a 100AH AGM on the tongue and will be adding solar. I will be going with the recommended Rich Solar setup (https://www.mobile-solarpower.com/the-minimalist-great-for-small-vans-and-cars.html).
What I am trying to figure out is how to best hook the Solar Controller to the battery. The Solar Controller has a working temp up to 113 degrees and the battery is in a metal tongue box. I am certain during the summer, it can go well beyond 113 degrees in the metal tongue box. So I feel it'll be best to have the controller inside with the rest of the electrical.
Inside the camper, I have identified the negative / ground bus bar (copper / brass in the picture - circled green). For the positive lead, I think the best spot will be at the master cutoff switch (circled red). There would be the live side and the switched side I could tap into.
Question would be: can I in-fact tap into this master switch as the positive lead and the negative bus bar for ground on the Controller? Or should I be looking to add dedicated leads back to the battery? There's an in-line 30a fuse at the battery positive terminal if that gives any idea what the camper is already wired for.
Additional note: the camper has a built in charger - when connected to shore power, it's charging the battery.
Thanks for any insight!
