Tesla Powerwall
The Tesla Powerwall is a rechargeable lithium-ion battery stationary home energy storage product manufactured by Tesla Energy. The Powerwall stores electricity for solar self-consumption, time of use load shifting, and backup power.
The Powerwall was introduced in 2015 as Powerwall 1 with limited production. A larger model—Powerwall 2—went into mass production in early 2017 at Tesla's Giga Nevada factory, with a more capable model with an internal DC–to–AC inverter—Powerwall 3—entering production in late 2023. As of May 2021, Tesla had installed 200,000 Powerwalls.
As Tesla Motors (now Tesla, Inc.) developed batteries for its electric car business, the company also started experimenting with using batteries for energy storage. Starting in 2012, Tesla installed prototype battery packs (later developed into the Tesla Powerpack) at the locations of a few industrial customers.
In November 2013, Tesla announced that it would build Giga Nevada, a factory to produce lithium-ion batteries.
On April 30, 2015, the company announced that it would apply its battery technology to a home energy storage system: the Powerwall. The device would allow customers to store electricity for solar self-consumption, time-of-use load-shifting, and backup power.
The device was initially announced to have power output of 2 kilowatt (kW) continuous and 3.3 kW peak, but CEO Elon Musk said at the June 2015 Tesla shareholders meeting that this would be more than doubled to 5 kW steady with 7 kW peak, with no increase in price. Two models of Powerwall were planned: a 7 kilowatt-hour (kWh) capacity model for daily cycle use (solar self-consumption, time of use load shifting) and a higher capacity 10 kWh model for customers who also wanted backup power. By March 2016, however, Tesla had removed all references to its 10 kWh battery from the Powerwall website, as well as the company's press kit. The production units would ultimately offer a capacity of 6.4 kWh.
Five hundred pilot units were built and installed during 2015, each being built at the Tesla Fremont Factory. The Giga Nevada factory started limited production of Powerwalls and Powerpacks in January 2016 using battery cells produced elsewhere, and began mass production of cells in January 2017.
The Powerwall 2 was unveiled in October 2016 at Universal Studios' Colonial Street backlot set. The Powerwall 2 had a 13.5 kWh capacity and was capable of delivering 5 kW of power continuously and up to 7 kW of peak power in short bursts (up to 10 seconds). Powerwall 2 devices were paired with a device called the Backup Gateway, which acted as a transfer switch and a load center.
