Building an RV in southern FL and AC is a must due to the heat. I have (3) new Suniva panels, 320w @ 24v, total 960w in theory. Outback80 MPPT.
The battery bank I am looking at setting up is (4) 6v Trojans, 435Ah each, series/parallel for an 870 Ah bank. Alternate charging and system power from a Honda (or Yamaha) 2000i.
The AC I wish to power is 410w peak operation...startup surge unknown... https://www.amazon.com/gp/product/B0...=ATVPDKIKX0DER With extensive (for an RV) insulation (spray foam + polyIso), I expect lower setting and economy mode to be sufficient to keep Peukert from killing this project before it leaves the gate. Hopefully something to the tune of 2.75A 20min per hour.
With other 110-120v requirements being microwave, computer, tool chargers, and toying with trying to mimic a ultra low draw 110 'fridge setup I saw, I wish to get a 3000w pure sine inverter. Magnum is out of my budget, so looking hard at a GoPower with a 0.5A idle: https://www.amazon.com/gp/product/B0...=ATVPDKIKX0DER ...would certainly appreciate other suggestions.
I've read through the "stickys" and see that I'm designing a system that exceeds what Sunking suggests for a 12v system. If I understand correctly though, moving to 24v would require doubling an already huge (for RV) battery bank to maintain the Ah needed to stand a chance at useful operation using no more than 50% capacity. I believe I understand the over-sized cabling and connections necessary to prevent this from being a fire hazard. Whether it turns out to be an expensive failed experiment is, however, something I feel willing to attempt. Any advice on any aspect would be great!
It's still in the very early stages, but if you're interested in the platform, build thread is here: http://www.cheaprvliving.com/forums/...-RV-Conversion
