Between our 15000 Coleman roof up front and the 9000 portable in the bedroom we are fine at 95 feels like 103 for two days. Humidity is 72.
EG4 now makes a couple that run on DC power...https://signaturesolar.com/eg4-hybrid-ac-dc-solar-air-conditioner-1-ton/https://signaturesolar.com/eg4-hybrid-ac-dc-solar-air-conditioner-2-ton/
Yep those have been around for a long time. I looked at those 4 years ago when we were going to put them in at the ranch but the price got pretty high with the setup we would need.But we sure like our roll around one I just put in the bedroom of the bus. It is in the corner and cools the whole room plus down the hall. I cut a hole in the side of the bus and ran the 6 inch tube to the fitting that goes through the side about 2-/12" x 7" tall and a 1/2" hole for the drain tube. I put a screen reister over it on the outside so it looks fine and works well. and the drain tube waters our garden too, LOL https://www.amazon.com/dp/B0C439ZXNG
You've got me interested in the one in your link. At 10,000 BTU its really efficient at 7.8A / 820W. We run only one foof air so this portable could be just that - for rear BR at night or front area OTR daytime..
With the increase in PV and other DC power generation DC powered appliances are growing. DC refrigerators and these AC units are great since as Fred states you avoid the conversion and get 100% power off the panels right to the appliances. The cited examples seem price competitive too.
Some interesting link's that I found on converting window AC unit's to mini-splits.https://www.fordtransitusaforum.com/threads/window-a-c-converted-to-mini-split-success.86312/https://sprinter-source.com/forums/index.php?threads/80984/
I just finished converting one of those into a split unit. I think it's going to work well. I'm going to try it in the bedroom, with the outdoor unit in the engine compartment. That's not ideal, but I don't need full capacity from it. For $400, it's worth a try. The conversion went fine though, and I just need to put it in the bus.
