Another 500W smart ups runs the 50", 2 iViews, Android TV Box, VCR/DVD, DVD, and some smaller electronic loads.
2 more 500W handle critical PC duties
I've got a 750W that is going back in service as soon as batteries arrive, and 2 more small 300W ones to take care of some other stuff in my "lab"
Another 500W handles 50", android box, and some small loads...
I only need things to run the 5 minutes it takes for the gen set to kick in.
Also if you get a Generac be sure you don't get snookered for the $300 monitoring gadget, when $50 with a Pi, and some wiring and few accessories will get you more and better gen monitoring. Unfortunately mine is older and the controller doesn't work with the software, sigghh...
If I had the space and could get a deal, I'd put in a whole house UPS but they are a little pricey.
The electronics stuff is the most important to protect from the normal spike/surges etc. of daily grid power, and then to keep online till gen set kicks in. Just today, a minor little storm with some lighting, thunder and rain, was good for about 3-4 "trips" of the UPS(s) in quick succession. Stuff connected to that directly would most likely be dead now. I figure I've save the cost of the the stuff, $$$$$ a 100x+ over. And batteries every 2-3 years is cheap compared to that price tag.
Size will be based on how long you want to run things, with no genset right now, then I think I would be looking at hack'en UPS by connecting larger deep cycle batteries to the UPS and/or solar standby with battery storage.
