The Tesla Powerwall 2 is not just an updated home battery, its part of a new ecosystem by Tesla Energy.

Elon Musk introduced the Powerwall 2 after introducing Tesla’s new Solar Roof tiles. The Powerwall 2.0 has more than twice the energy storage capacity with 14 kWh capacity. Musk said the Powerwall 2 has enough power to charge lights, sockets, and a refrigerator for a 4 bedroom family home for an entire day.

The Powerwall 2.0 is similar to the previous version. It’s a large, rectangular, box thats usually depicted being mount in the garage, next to a Tesla Model S, and now Tesla Solar Roof tiles. The design is now flatter and more angular looking, but essentially the same.

The Powerwall 2.0 will be available for $5,500 per unit.
