12v and 110v and techquestions

Thanks for the input,

I find it hard to believe how little information there is when it comes to rvs, no dimensions in the floor plans other than beds and awnings, no appliance list, one to 3 pictures shot from weird angles, and just vagueness. I've been looking to YouTube for most my answers/ pictures.

I am at this point tempted to leave the existing 12v setup alone for simplicity, and doing an invert/charger 48v to power some of the 110v outlets.

Figured id need to get some sealed batteries anyway to bring inside. I could then, if I wanted to run an mppt charger and run some power over to the 12v.

Comparable ACs I looked at ran at 600-700watts(8000btu window unit), I'd have to look at their ratings closer to make sure I account for the stalled motor on start up.

Again this is all in my head at this point, I figured if I ever had enough cells to do 48v, my total watt hours would be significant, I'm not really concerned about running the AC but I figure its low enough to be doable, it also not a concern because the location I would be in is pretty arid, so just being in the shade would be comfortable.

I was looking at the thin film solar panels, I think they are roughly 42" x 22" for 100w, but their downside is their peek voltage is ~17.8v . With most 12v mppt chargers i am looking at sets of two in series, and large a amperage running through the wires.

If I could have my way it would come without the skylights, the area I might be in is subject to a lot of high winds, I wouldn't want those thin skylights for that reason alone, figure they would pop in and out and annoy me while I sleep. That and leaks and I'm pretty sure the material they were using will degrade with UV light over time.

I figured a solar setup would cost as much as a nice pure sine inverter generator, and be nearly silent, and give me the anchillary benifit of beefing up my electronics a bit.

I'm not buying until I find what I want anyway, that and I'm not looking for anything till fall at the earliest.
