The electrical code will put a crimp in some of your more grandiose
plans. The "switchable outlets" are probably a no-no.

If you have a whole-house generator (or, presumably, battery system)
you need a "transfer switch", which is an idiot-proof thingy that --
whatever idiocy you perpetrate within your house -- won't allow any
of your backup power to leak back into the commercial power lines
to kill the people working to repair them.
