Thanks for bringing more details to the thread - We've just launched, and for folks who like what they see and want to be first to get Pila the (refundable, cancel anytime) $99 deposit will lock in $999. Once we start shipping and fulfilling through other distribution channels, price will increase to $1299
Also, spot on that the average home draws about 30kWh, and with an EV driven average daily ranges that'll jump to about 60kWh.
This is an interesting idea and I wish you a good luck building a profitable business around it.
Before starting to apply voltage to a home electric gird, I guess you need to disconnect it from the central grid - how do you do that? Or do you detect when the grid goes down and comes back up?
The point IMO is not to backup your whole home though. That already exists with Generac (20-50K if you need to dig a new gas line) or Powerwall (10-20K depending on electrician and needs). All need permits.
This is meant as a more precise, room-by-room backup solution!
Given these stats and the price in the sister comment, this costs $24,400 for a day of backup.
This makes the LCD displays on the front page of the website listing "5 days 6 h ours" and similar on a single unit very misleading. That amount of backup would cost $128,000.
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.
I couldn't find a price on the website (the $99 is just for a reservation) but from this thread it looks like it's priced at $1k [1].
For context, in the USA, 30 KWh is a rough estimate for average daily home usage [2].
