After launching itself into the electric cars market, the US manufacturer Tesla marketed a Li-On battery to be installed at home, to store the energy produced by photovoltaic panels, wind farms or mains electricity in off-peak hours. Baptised Powerwall, the device is available (in the United States) in capacities of 7 and 10 kWh (3000 and 3500 USD respectively), that can be grouped to reach a total of 90 kWh. In Europe, the Bluestorage system developed by the Bolloré group already markets the same type of services, but based on LMP (Lithium Metal Polymer) technology.
