You can buy a 200amp / 22kw standby generator for about $4500.
How long does a 10 or 15 kwh battery power a typical home?
My power bill shows I used 42kwh per day last month.
So the Tesla battery would last me.... 8 hours?

Yes, you are correct. But usage is higher during the day and less at night. Home peak is typically the evening - Cooking, TV, lights after sundown and still a very warm part of the day (AC).
