Electric vehicle manufacturer Tesla is moving into the home energy space with a home battery storage offering.

The "Powerwall" home battery storage devices will come in two models:

• A 10 kWh model, costing $3,500, for backup applications

• A 7 kWh model, costing $3,000, for daily cycle applications

Costs do not include a required AC-DC inverter and installation

The unit is said to mount "seamlessly" on a wall and is said to be completely automated

Powerwall begins shipping this summer and requires installation by a trained electrician

The BBC reports that  Tesla CEO Elon Musk, "said the company would partner with SolarCity to install the home batteries, but there would be more companies announced."  Musk is also the chairman of SolarCity.
