I am a complete noob with regard to solar power battery charging systems, but I think I want to add a battery trickle charger to my 2021 Solitude 310GK. I have no interest in off-grid camping, but would love to keep my battery charged while in storage.

I believe that there is wiring from the roof to the inverter area, but beyond that, I know absolutely nothing.

Could anyone offer any words of wisdom or suggestions?
