There are c omnpanies, like Tesla that make whole house battery packs that are of course re-chargeable through either solar panels or house electric. One or two of those can power a house for a week left uncharged.
For certain applications this makes sense. More rural locations with land for panels to keep the battery packs recharged could be a good choice for some.
This is a bottom up approach that consumers like—the cost benefit. For some, it doesn’t work—for others it does.
Not my house. My battery stack (not expensive Tesla) holds a large 92kWh capacity (which is very large for residential). Since I drain them at most 70%, call it 63kWh of useable storage. Yesterday alone my home used 66.6kWh. The day before that 67.9kWh. Etc. Obviously the battery stack can't be charged once and hold enough power for a week of my home's needs. (In my case it's an all-electric home and my wife and I drive our EV about 1,300 miles per month. So we need lots of power on a normal day.)
To your point, I haven't had to pull from the grid since April 12 (of the 66.8kWh my home used that day, 12.8kWh had to be pulled from the grid). But that's because I had lots of solar come in during the past 30 days (more than we needed).

Tesla Powerwall

14 kilowatt hours for $20,000. It provides 14kw FOR ONE HOUR if fully charged.
Generac 15kw generator provides 15kw for as long as it has fuel. If it runs on a natural gas line (e.g. at my house) it provides 15kw FOREVER.

And it costs $5,000 not $20,000.
But if Democrats want to freeze in the dark, that works for me, it prevents them from having time and energy to harvest ballots at nursing homes and perform at drag queen story hours in front of children.
OR in rural locations you could get a diesel, propane or gasoline generator and a really big tank for the fuel.
Almost everyone here in NH has a back up generator now. They are hard wired into your main panel through either a Gentran switchbox or a whole panel disconnect.
I have the first kind. It powers ten 15 amp circuits. Two or those power my well pump.
I have a Honda gasoline generator. My house is 50 years old.
The issue with gasoline is that IF its a big enough power outage sometimes the gas stations do not have power.
Most newer rural houses have propane heat. So, they also have a propane backup generator. Then they usually have a big underground tank. That you can run your house for a couple weeks.
Natural gas is typically not available unless you are in the cities or really large towns. I am in neither.
