Light-Weight Tiny home.

[mo.travelin]

Trying to design the lightest-weight family-size mobile tiny home possible. So are family can be mobile using a Model X.

Original plan SantanSolar solar panels, secured via super struts, connected to an EcoFlow for plug-and-play.

I want this to be the lightest system possible.

Still using SanTanSolar panels. What would be the best other components?

Would need to power: refrigerator, tankless water heater, water system, induction stove, convection oven, projector, etc.

Also can one use an EV as the extended battery?

Respectfully,
Mo

What is the towing capacity of the Model X?
Typical 'Tiny home' is a 7-10 thousand pound twin-axel deck trailer with a DIY structure above it. Unlikely a car will be rated to pull that.
RV's are available in fold-down configuration and many are designed to be super light-weight with aluminum frames and soft shells to stay light as possible.
Eco-Flow, & "tankless water heater" - better be propane.

Also can one use an EV as the extended battery?

as long as you have V2L connections, most new EV's have this, most older than 2018 don't from what I have read.

Maybe you need to consider a larger tow vechical - F150 Lightning or GM Silverado EV. Others soon to be on the market.
It seems the main problem with trailers and Solar - is never having enough roof space to mount the number of panels you reaaly need. Campsites with power supplies may be a better option, especially if they charge a flat rate for the electrical hookup.

Someone noted on the forum a new trailer design with a large LiFePO4 battery built into the trailer - to be used to assit the EV tow vechical - could double as a large ESS for your loads. I think it would be easy enough to build a trailer with a slide out battery bank under the floor (set between steel channel frames).

Edit: looked up onlinie - Model X 20 inch wheels =5000 lb max trailer weight, Model X 22 inch wheels = 3500lbs max.

If weight is the primary concern, you'll need to skip the 50lb SanTan panels and pay out for some CIGS flexible panels. Aluminum C-channel and the corrugated plastic board and you can get multiple times the same power for the same weight as a single 50lb SanTan panel. It's gonna cost you though, flexible panels run at least $2/watt. Look up RV'ing with Tito on Youtube, he's pretty much nailed the lightweight-to-power setup.
