I was wanting to know if it would effect my House battery system. (draw them down) Because the Owners Manual say's to make sure the engine is running when you plug the 12DC plug into the cigarette light plug. Also, the OM says that because it's set for continuous it will only run on the provided battery for 0.9 hrs. And of course, I can't find my OM for my Xantrex Inverter.
I have 6 house battery's Interstate U2200 6v. I also have a Xantrex Pure Sin Wave Inverter 2000w. And 3 100w solar panels.

I run my BiPap machine on the house battery's and have no problems. I was just wondering if the Portable Concentrator would run also?
