It sounds like you have a standard system with one main GTI in a big box hanging on a wall somewhere. You should check the brand and model info. If it's a brand-name company that has a website, they might carry the hardware needed to switch back and forth between On and Off grid.

I'm not sure that it's a good idea to set up for off-grid without a battery bank. Since clouds tend to vary PV output a lot.

Trying to find something that might be a good back-up for my wife's CPAP Machine, that be re-charged by the grid and maybe by a PV panel.

I don't want to rely on my very old Lead Acid battery bank, or go out and crank up the gas generator when it's -4 degrees in the middle of a blizzard.
