Tesla Powerwall home battery revealed, rechargers from solar panels

Tesla is introducing a new energy product called the Powerwall home battery which is rechargeable using electricity produced by the solar panels. Tesla is not just an automotive company, it’s an energy innovation company. Tesla Energy is a critical step in this mission to enable zero emission power generation. The Tesla Powerwall is a rechargeable lithium-ion battery designed to store energy at a residential level for load shifting, backup power and self-consumption of solar power generation. The Powerwall consists of Tesla’s lithium-ion battery pack, liquid thermal control system and software that receive dispatch commands from a solar inverter. The unit mounts seamlessly on a wall and is integrated with the local grid to harness excess power and give customers the flexibility to draw energy from their own reserve. The battery can provide a number of different benefits to the customer including Load shifting and back-up power storage.

The Powerwall Home Battery increases the capacity for a household’s solar consumption, while also offering backup functionality during grid outages. The Powerwall is available in 10kWh, optimized for backup applications or 7kWh optimized for daily use applications. Both can be connected with solar or grid and both can provide backup power. The 10kWh Powerwall is optimized to provide backup when the grid goes down, providing power for your home when you need it most. When paired with solar power, the 7kWh Powerwall can be used in daily cycling to extend the environmental and cost benefits of solar into the night when sunlight is unavailable. Tesla’s selling price – in the US only as of now – to installers is $3500 for 10kWh and $3000 for 7kWh. (Price excludes inverter and installation.) Deliveries begin in late summer.
