I seem to recall almost two years ago when I was getting info on a possible solar install, we had the options of LG batteries or Powerwall, and one of the specific points of difference that the more expensive (and larger capacity) Powerwall battery install provided was stated to be power when the grid was down.
I can't speak to the accuracy of that, as I was speaking to a salesperson and I didn't go forward with the project so don't have any personal experience to add.
