My Dream: Solar only heat pump 2007 C2 5 window

Mitsubishi 26.1-30 seer 9-12k btu heat pump
http://https://www.ecomfort.com/Mits...AH/p79445.html

All. I know this dream has been beat to death; it canít be done. But can it with new tech, since the question was last asked? Or Maybe this Wicked Weed Double IPA is just too strong!

Basically can 1320w - 1980w of high efficiency solar (4-6 330 watt panels) on 500-600ah of LiP4 Lithium 90% deep cycle house batteries and a 4000w(12000w peak for 20s) AIMS 110/230 inverter work to power the above Mitsubishi mini split heat pump a few iPads, a laptop and a small fridge???

Dreaming of a simple, quiet, low maintenance solution to heat and air while parked and used in conjuction with dash air while driving my 2007 C2 5 window, that will have 2.5 inches of sprayed close cell and heavily treated windows (magnet insulation blankets / passive shading). This bus is white and the solar panels will be covering almost the whole ceiling with an air gap to act as passive shade.

I donít want a generator (other than a small emergency Honda 2000w), shore power or propane.

Someone linked me to broccoli bus. That dude is Batman. Anyone else done that shorty sized? I’m going this route, but lot to learn. I need to source the right car battery bank I believe, due to the nasty price of LFP

Frigomar's variable speed brushless inverter tech is apparently amazing, their 16000btu unit uses under 1400W. Maybe $4K installed?

Power that off 2000W solar directly, otherwise use the Honda.

Do not bother trying to power for long off batteries.

Each 100AH only buys you an hour or two of time shifting, and you won't get it all back to Full running aircon at the same time.

LFP is the way to go but yes pricwy.

3-4 of well installed insulation around a small living space will help.

Frigomar looks awesome. Can’t afford that much on any one component or this whole build suffers. Need to find tiny home gear, marine stuff is outrageous. I am looking to get thru a weekend of 90 degree weather without starting anything. That would be a simple goal. Not having a generator, propane, Black tank, etc of all these competing fuel sources saves me time and complexity. That’s worth something. Just not new LFP or anything that says marine or Webasto

I plan on dipping the bus in spray foam by its heel

Dreams take money.

Otherwise MaxxAir + getting outdoors more.

Don't mess with EV packs.

What’s wrong with EV packs? Seems like quality AH for cheap if I can deal with the voltage and packaging
