Batteries or Generators don’t just let you cook and stay warm when the power is out but do everything else such as keep food cold as well.

Do induction cooking tops work well on batteries (or generators)? IIRC our induction plate has two-phase power because it can pull more than 3.6kW.
Sure, as long as you size the system to expected loads.
An 8kW generator suitable for occasional use is only ~1,000$. A Powerwall 3 does 11kW continuous and peaks at 30kW for transitory loads like starting heavy equipment.
The most convenient solution where a generator automatically kicks in during a power outage requires an electrician and extra equipment, but there’s also real tradeoffs to having gas lines going to your home.
There is a good technology connections video about building backup batteries into the actual stove.
I think part of the problem with whole home backups is that they tend to be sized to a maximum load that is unusual or could be avoided with some effort. And that providing a backup for the essentials you actually need is relatively cheap and uncomplicated if you make some modest sacrifices.
There are models that include a battery to reduce the input power requirement. That's not quite the same as the question, but it answers it, you just need a big enough battery and they are fine.
