Yep! Pila qualifies for the 30% Federal Investment Tax Credit (ITC) under the Residential Clean Energy Credit if your Pila system exceeds a total of 3 kWh capacity through either:
Two or more Pila batteries (1.6 + 1.6 = 3.2 kWh)
One Pila battery plus a Pila Expansion Pack (1.6 + 1.6 = 3.2 kWh)
Energy arbitrage value depends a lot on your utility, agreed. For most home battery systems it's a 5-7 year payback, even with solar. In my experience most folks investing in these systems are also putting a lot of value on the backup power, and from the data/insights. The average fridge in the US has $300-500 of groceries inside, and some insurance providers offer as much as $600 per outage to pay for spoiled food. So for folks contending with frequent outages, we're excited to offer more peace of mind value while delivering some additional smart energy management value on top
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'd love to see the price continue to come down, so more and more folks can get these products. Compared to the expensive install of a large battery systems, I'd call it a step in the right direction but I agree we need to make these even more accessible. Features like energy management and demand response can improve the economics in some markets, but low upfront cost is the ultimate goal. Most of my family in Louisiana are similarly not considering smarter backup systems seriously because of the cost and either "do nothing" in outages, rely on neighbors' generators, or have unreliable pull-start generators in their garage.
Yes, yes, and yes on offline performance! We're on it!
Appreciate the question! The coordination is similar to what a whole-home battery might be doing for you, depending on how you configure it: Timing charging to follow real-time solar production, energy arbitrage to shift home usage to times of day when electricity is cheaper (e.g. TOU rates, big in my neck of the woods in California), "storm mode" to charge up automatically when severe weather alerts are issued, and eventually things like Demand Response for grid services which you can get paid from if you opt into. Beyond the battery control stuff, locally sharing energy data across the batteries across your home can help build a model of energy usage to help make sense of your usage, look out for anomalies in your home wiring, and more -- And doing this with a local connection just means it can be a more reliable, more resilient system, even providing this sort of value when internet drops out
Yep, and to clarify Pila includes an MID onboard so while Intentionally Islanded there is no backfeed. But in terms of a whole-home disconnect, I believe we'll see more generic options appear that are somewhat DER-agnostic.
The Tesla MID is in the Tesla Gateway or Backup Switch meter socket adapter. The Pila MID is onboard inside the battery. Pila can push power back through the plug.
When utility power drops, Pila & Powerwall react exactly the same. They both detect the outage, open the MID, and power load downstream of the MID. In the case of Pila it powers loads downstream / plugged into Pila.
The off-grid detection is based on a combination of voltage and frequency measurement over different time windows, so I'm sorry that I won't be able to give you an exact answer on your situation. I've lived in apartments with bad high impedance neutral connections and it did all kinds of weird things to the loads... Hopefully something your apartment complex can look into!
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?
This audience is definitely more up on tech - I've been surprised how often folks I talk to have never heard of UPS's!
We know we're not the first people to think of automatic plug in backup :) Aspirationally, we aim to do to the UPS what the Powerwall did to the lead acid battery bank -- Bring it into the 21st century, level up to better technology, add software intelligence so it's not sitting idle 99% of the time, and improve the design and usability to make it a more exciting and valuable product for more homes
Good clarification! Smarter backup batteries like Pila or Powerwall can be configured to dynamically charge and discharge, giving the benefit of outage protection and energy management. For example, charge up from the solar power you produce at home, and use that stored solar power to offset energy usage at night or when utility power is expensive. They they have a "backup reserve" setting which allows you to set a minimum charge to always be stored for an unexpected outage. Smart features like "Storm Mode" can use severe weather alerts to automatically charge up to 100% ahead of an outage to ensure you're prepared for possible outages
It can charge when energy is cheap & discharge when energy is expensive. If you have solar it can charge when solar is producing and discharge at night.
