TESLA- HOME BATTERY
Launched in Los Angeles on April 30th, Powerwall is a home battery system that uses lithium-ion storage batteries that let homeowners save surplus electricity produced by photovoltaic panels during the day for use at night.
Powerwall comes in two sizes: a 7 kilowatt-hour (kWh) lithium-ion system and a 10 kWh unit. These units provide 400V of direct current and can be hocked together to create higher kilowatt-hours. Later this year, a commercial version called Powerpack will be available for consumers. This will have a capacity of 100kWh. These too can be plugged together to provide up to 10 megawatt-hours(MWh).Read full article on www.teslamotors.com
