Yes there is power loss in the inverter. That being said, do you know how much batteries will cost? Enough batteries to run lights for a house for the night, much less an AC unit? Can you get DC AC units? I imagine not.

Off the grid is cool and I'd do it if I were a bazillionaire, but alas I'm not. Honestly an off the grid system would probably cost 1/2 as much as my house.

I know a fellow who recently built an off the grid house for a rich guy. The guy wanted spray foam for insulation entirely. It cost $60K for insulation alone. I don't know what the power get up cost but I was told that the cost of the insulation was nothing in comparison.
