At the gym and trying to take in information on RV electrical systems. It's sort of the absolute most dangerous part of the Van build so I tend to keep looking at information trying to comprehend it.
For instance, I live in Texas. And if I want to be autonomous I need to have an Air Conditioning unit setup. Dad thinks knocking out a rear window and using a "Disposable" window unit is optimal. Because if it breaks you throw it out and get a whole new one...
Because repairing something that can be repaired costs money or something.
That particular AC unit, with no thermostat or energy saving controls at all runs about 500W on the box. Which to make it 8 hours still means battery. And since it has no actual thermostat, just cooling it doesn't stop and save power when it's cool enough.
So a 24v 100ah battery not counting DC to AC conversion and the power to run and inverter at 2400Wh would run it for 4 hours and change.
But I don't care for the setup and the disposability bit actually doesn't thrill me.
A 24V DC backpack mini however can use from 800 to 1000W. Which means that 2400Wh drops from 4 hours to 2 maybe.
I would prefer this method though because repair is preferred over disposal.
Just things like that work in my head.
I am planning my systems to be as efficient and autonomous as I can. Minimizing the DC to AC power conversion loss is part of it.
