For folks that are looking for true whole-home backup, with every load protected, investing in something like a Powerwall would be the way to go. I don't see Pila trying to compete with whole-home systems. We were inspired to build Pila because many folks I've spoken with over the years are most concerned just about backing up a few key loads (fridge, wifi, charging phones, some lights). For them a $10-30k whole home system is a lot of extra spend, and if they rent those systems may be off the table to begin with.

I assume it least has enough smarts to only show the battery capacity for whats in it. It can't run a whole house, so comparing it against an entire household's average load might be unrealistic.

Correct, 1 can’t run your whole house, but you can get 1 per room and backup your whole house that way.
