Obviously, this is a topic. Something I have found in my research. An AC unit is rated at its maximum draw, which is when the compressor is running. The rest of the time it draws far less current. From my research online, this is usually from half the time to nearly always. But I presume this is in a dwelling, and not a camper. My custom build will include very well insulated walls with a radiant barrier aluminum skin and 2" of R10 foam board. It will essentially be a walk in cooler with a sofa. In considering solar, I'm guessing my compressor will work 1/4 to 1/3 of the time. This brings me into the 400W 600W range, although I am planning closer to 800 just to be safe. I will also have a propane generator, but I just don't want the noise when I can help it. Other considerations. I have an LG dual invertor window unit that costs amazingly little to run and will freeze out a penguin. This of course is all theoretical. I'd like to hear from people with real world experience cooling their campers. What is your setup (BTUs) and what have the power demands been?
