Not being up to speed on all this stuff, I will ask a naïve question. I don't know how much air you need Cecil, but I do know there are a lot of relatively inexpensive 12V aerators available for live wells etc. Does just putting in some kind of smart switch box that knows when the main power dropped out and kicking in a canned 12 V system make any sense from a cost standpoint? My home backup generator has a small trickle charger that keeps its battery always charged.
