Well Stormy, my book learnin is a bit old, but when I went to school, the inverters had the electrical components inside that allowed just that type of action. They can do this to power key loads such as emergency medical devices and things like a freezer, and not send anything back to the grid. This would work for solar or a generator. You would either need to pre wire circuits in the main panel, have the power go to a separate panel, or just have an extension cord or two that then could power the devices that need the constant power. The next step up from that would be a non grid tied system where you keep it all...all of the time. The main problem with all of this is even if you have a "transfer power switch", you need to make sure you are not back feeding or "islanding" power back into the grid. This could kill a utility worker who is working on a power line he thinks is dead.

Excerpted from bullionstacker.com about a post 'cane solar setup... but which I imagine could be used 24/7 too
"1500 watt pure sine inverter, one I know is RF quiet so you can receive radio signals https://www.solarblvd.com/products/saml ... verter-ul/ $455.33
Charge controller https://www.solarblvd.com/products/blue ... ontroller/ $178
Cheap deep cycle boat battery from Walmart $150ish...
Pair of 180 watt solar panels https://www.solarblvd.com/products/sola ... panel2018/ $312
$1,095 + shipping(maybe another $60), find a portable box to mount it all in just about anywhere... those rolling tool boxes with a big drawer on the bottom for the battery work well. Can make a portable stand for the solar panels, just make sure it is well weighted down so wind can't tip it. Or make a permanent rack and only mount the panels when needed after the storm has passed."

There, fixed with proper links.

Looks like these put together with the proper sized wires should give you a solid unit that should provide the power you are needing.

A slight modification from the previous posts, reflecting price changes and substitutions of size.
