And of course 200 Ah (@12VDC) is 2.4 kWh. BTW, I have a couple of these LiFePo 100Ah batteries, and they are great. But I do get a kick out of how the capital cost is about $800 USD to store 1 kWh, or $0.15 worth of electricity (omitting solar cell cost solar charge controller cost, which are comparatively minor)! Still, the grid independence (for sustainable Tiny Electrical Living) is a wonderful thing.
