Phil, Bad idea. There is absolutely no financial advantage to going off-grid, at least if the grid is already installed. Batteries are a lot more expensive per kWh than grid power.
And pretty soon they will be at war with each other over "who left the d**n loads on and drained the battery". They should just do a straight grid-tie system, or separate systems for each business, to offset the utility power usage. Of course, grid-tie with battery back- up of critical loads might be a good idea, if they truly have critical loads. That said, I hear that the reanimated Satcon is developing large battery-based inverters. I haven't checked on their progress lately though.
