Tesla batteries that can power homes

Tesla who are known for manufacturing electric cars have unveiled batteries that can power homes and businesses.

This is latest technology the US electric carmaker have revealed as it attempts to expand its vehicle business that very well known for.

The batteries could store solar energy and serve as a back-up system for consumers during blackouts. It can also be used for allowing consumers to get off the power grid and bring energy to remote areas that are not on a power grid.

The rechargeable lithium-ion battery unit would be built using the same batteries that Tesla uses to produce its electric vehicles.

The system that manages the batteries is called Powerwall and can be bought for $3,000 (£1,954) for a 7kWh unit. The 10kWh unit will retail for $3,500 (£2,275) to installers.

Powerwall units can be attached to walls. Buying additional units can be attached along with each other to combine its power and the ability to store more energy. Only up to nine units can be attached to each other

It estimates that one kWh can power a laptop for two days, full washing cycle and boiling a kettle 10 times for two days from the energy comparsion firm, USwitch.

Tesla energy reveals this is a critical step towards a future for zero emission power generation.
