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.
