The battery itself, within the unit, is approximately 8x6x4 inches and weighs perhaps 35 lbs or so. A unit holding many batteries would be far more compact than a stack of UPS cases. A stack of batteries could be configured to provide temporary power for larger draws like microwaves & AC units. The biz case is a synergy that increases the sale and efficiency of clean energy inputs, grid connections, architecture/design with innovative features, and anti-EMF control of the building design (i.e. improving the dirty ground input from the power company is 1 of the most important steps) alongside the use of non-attack wires. It would also sell more battery/UPS circuits.
