When you are plugged in, the Pure3 system has nothing to do with supplying power in your Van/RV. The electrical system automatically senses that is getting outside power and uses that for everything, including trickle charging your batteries. Someone commented above that they do not power share. That is exactly right. So…
I only have 110/120V input built into my van. I have a 13,500 BTU air conditioner on the roof. It is the Coleman Mach PS model, and I have absolutely no trouble running it whatsoever plugged into 15A/110V household plugs. But, I can attest that the average air-conditioner will run, because on my former Winnebago, I had a regular 13,500 BTU air conditioner that I couldn’t run all day long while plugged into only the same voltage outlet. I could not (former Winnebago) however, run the air conditioner & the microwave at the same time. Nor could I use use the vacuum cleaner & the air-conditioner at the same time.
Actually, with my current set up, plugged into the same standard 110V… I can run the air conditioner on high, and still run a 3A battery charger and have all my devices plugged in and charging at the same time.
So the short and direct answer is “YES“ that air-conditioner on your roof will run if you’re plugged into 110 V outlet. Just try not to use much else.
