It's a waste of money to go off grid when there is a perfectly good power line right outside of your house.
The tesla power wall is an over priced toy for the rich, just like almost everything else they make.
It's not the best, it is the newest and just because some thing is new doesn't automatically make it better than what was in use before. I find the people most impressed by the power wall don't have any idea what the existing tech is like.
The best is still low voltage DC modular charger and inverter systems powered by lead acid.
