Interesting. Link?

They’ve already bought it so...

Know there are a number of state/fed discounts on it that bring the price down. It also seems like there’s some kind of power shifting thing in 2018 with more rebates and a potential to save money by paying for low usage rates only (by presumably using the battery during the day).

Generac, Briggs&Stratton, and Kohler make many generators that are powered by LP or natural gas. These typically start at 10KW or so and go up from there. Powerwall is 5KW sustained and it lasts less than 3 hours at 5KW, after which you're without power again. Natural gas powered units cost about half as much and can run indefinitely. Indeed people even use them to power their cabins and such, with LP delivered only once or twice a year.
