What is the name of Tesla's home battery product?

Tesla’s home battery product is called Powerwall.

Powerwall is a rechargeable stationary battery designed for residential energy storage. It can store electricity generated by solar panels or electricity drawn from the grid, then supply that energy to a home later, including during a power outage.

Tesla introduced the original Powerwall in 2015 as part of a broader move into energy storage. The product is distinct from Tesla’s vehicle batteries and from its larger commercial and utility-scale systems. Megapack is intended for large-scale energy projects, while Powerpack was an earlier commercial battery product.

Powerwall 3, released in 2023, integrated a solar inverter into the system. The current Powerwall 3 specification lists 13.5 kilowatt-hours of energy capacity and 11.5 kilowatts of continuous power. “Home Battery” describes its function, but Powerwall is the product’s canonical name.
