Tesla is preparing to launch Powerwall 3, the third generation of its home battery pack, according to information obtained by Electrek.
In 2015, when launching its Tesla Energy division, Tesla launched the first generation of the Powerwall, and it quickly became, by far, the most popular home battery pack in the residential market.
Shortly after, Tesla launched Powerwall 2, a new version of the residential battery pack with more energy and power capacity.
It also features a sleeker and more squared design:
Tesla has been installing Powerwalls with nearly every solar installation, and solar installers, like Sunrun, have also adopted the product as the company ramped up the production capacity to over 4,000 units per week.
In 2021, Tesla launched Powerwall Plus, which includes a new inverter and higher power output.
Each of these iterations has helped Tesla hone the product, which has quickly become the main product people think about when considering residential energy storage.
Last year, Electrek reported on an internal meeting at Tesla where Seth Winger, senior manager of solar products engineering at Tesla, confirmed that the company was preparing to launch new home energy products.
Now we learn that Tesla is about to launch Powerwall 3.
Electrek has obtained confirmation that Tesla has applied with some electric utilities to have a new product named Powerwall 3 approved as certified equipment for connection with those electric utilities.
Unfortunately, the new specs or features are not listed in the new certification, but based on what Winger said last year, we should expect three main upgrades:
- Easier installations
- Better aesthetic
- Higher performance
Considering Tesla Powerwall 3 is already certified by a handful of electric utilities, we expect the product to be launched soon.
Electrek’s Take
What can we expect from a Powerwall 3?

I predict a shift from NCA to LFP -- and other changes in chemistry. Very likely the output & capacity will stay very close to where they are now, but the price per kWh will drop. When paired with Tesla solar, it will charge directly with DC; when paired with a Tesla charger, it will output DC directly to the charger -- and might allow 'balancing' between the Powerwall & the vehicle. Maybe there will be a direct output of various low-voltage DC currents to support electronics -- a home file server, LAN, firewall, modem, etc.
Tesla has consistently increased the power output of the Powerwall, but it hasn’t increased the capacity from 13.5 kWh since Powerwall 2 in 2016.
It would be nice for Tesla to improve on that front, but it’s not necessary since the product is stackable. That said, most installs include two Powerwalls, so it could be sensible to try to have those work with a single device.
Throughout all energy products, Tesla has been focusing on making them easier, faster, and cheaper to install, so we can expect that with the Powerwall 3.
