Skolkovo has developed a universal analogue Powerwall by Tesla
WATTS Battery System, created by Russian developers, is made up of individual blocks that can feed electricity to anything. Charging system from solar panels, windmills, generators and even sockets. A charged battery can provide any power home appliances and does not require fastening, can therefore serve as a stationary or portable power source. Therefore, if necessary, WATTS Battery can take with you on the nature.
Battery capacity is 1, 2 kW / h, and it is already fully operational element capable of storing energy and feed devices. If the user requires a higher capacity battery, it can simply purchase additional units, based on their needs. The weight of each block - ten kilograms and the maximum system capacity can be increased up to six kilowatts. For a small home or apartment would be enough for four or five blocks - their capacity will allow electricity to feed the TV, computer, refrigerator and lights for over ten hours.
Perhaps the only thing that stops on the immediate purchase - the price: the cost per unit is now $ 3,000. And it's quite a lot. It is easy to calculate that four blocks required for an ordinary apartment, will cost 12 thousand. However, there is hope that the developers optimize and refine the technology, reduce the cost of production of batteries. Then zazhivom.
