Torture test of the solar A/C

Good to hear that you were able to run the window unit for that length of time. 40 amps continuous, I can only dream.....

I don't know what your overnight temps are but here in MN, it gets down to 60-65F most nights. If you start off in the AM with the night air in the trailer, I bet the 5K unit would have a better go at keeping temps down through the day.

Also churning under my thinking cap, how much additional draw is an 8K or 10K unit? The Mitsubishi splits are also noted for their efficiency. I'll have to look at these specs if I forge ahead down the AC trail.

Thanks for posting, Jim. I'll be subscribing to see how your torture test ends up.

It only took a few hours after night fall for the air outside to be cooler than the air in the house was even though the A/C was running. At that point I turn off the A/C and open the windows as that will cool the house faster.

I did look at a few 6000 BTU units and larger but I believe I'd have to be able to push 50a and that would require a fourth panel as well as building a rack so that it would fit on the trailer. That would max out the controller and believe me, it was running hot to the touch just pushing the mid 40's for 6 hours.

Four panels would be 60a, good thing I got the 1/0 eh? lol

I will be interested to see the concept expanded. I am hoping that now that there is proof that it is feasible that it will get others moving in the same direction and hopefully come up with a better solution than I have.
