I have a stand alone 30 x 40 metal building with 30 amp service for my rv that I am going to insulate with closed foam insulation. I am trying to determine the best method to install an ac unit. Was looking at stand alone 24k btu solar powered minisplit ac unit or should I do some kind of solar/ inverter/ battery setup? I would not be doing any evening work. So ac at night would not be necessary. I live in Las Vegas, on 5 acres, ground mount prefered and sunlight is abundant. Maybe Will Prowse would like to do a start to finish youtube video?
