How To: run window air conditioner on solar - John61CT - 03-01-2018

A large LFP bank and a charger+genny that puts out say 4 times more than the aircon consumes, could run 24*7 with the genny running say two hours out of every eight.

Maybe $8k worth of gear though, plus fuel costs, lots of space and weight.

With enough solar you might eliminate a third of the genny runtime, say $2k added costs.

If you have enough $$$$ to experiment (thousands) you may get a setup that would work, when the sun shines.

My 2000--watt inverter generator simply works.... all for $375.

You can build a large enough solar/battery/controller/inverter setup that will work for $2200.  And then you have unlimited power for everything, not only the AC. Not an experiment, because I have it, run microwave, 12v fridge, normal coffee maker, 5k ac, ice maker, etc. Useful year round.

I don't understand this whole AC stuff. the last thing I want to do is sit inside a van/RV all day, I want to be outside doing something. I just go where it's not so hot. I would go crazy if I had to be cooped up all day. well crazier anyway. highdesertranger

Like Itrpper my solar does so much more for me than run the A/C. I would love to discuss it but maybe in a thread about the differences of using solar vs a generator. This thread was intended to discuss the requirements of what it takes to run a A/C.

My sentiments exactly.  When I get back out there I'll be on the move every 2 weeks or sooner if the weather becomes a big meanie.  I'm also gonna assemble a small swamp cooler in case I get stuck for a day or two in warmer than sleeping comfortable weather.  Just like in real estate sales...

To run a 5000-8000 BTU window air conditioner ,how many watts Solar panel, solar generator and gas portable generator?  EXAMPLE: some people are using 1000 watt portable gas generator to run a 5000 BTU AC. Some people are using 950 watt solar panel to run an AC

Good luck

I think the answer is very clear, but has two steps:

1. Size your battery bank and inverter sufficient to run your Air Conditioner.

2. Adjust your lifestyle so that you are moving to higher elevations when it gets hot. Or if you can’t be mobile (living in someone’s driveway to take care of a sick friend) acquire enough supplementary power to back up the solar power when your bank runs out. Eg: your friend should provide you a 20A hookup while you’re there.

There’s absolutely nothing wrong with wanting to run an AC, sometimes circumstances mean you can’t relocate right away....
