Distributed energy storage company Eguana Technologies has partnered with lithium-ion battery company LG Chem to launch an AC battery for the North American residential market by the middle of the year.
The AC Battery, which is expected to be available for commercial shipping in about three months' time, is an energy storage solution that can be paired with energy storage management systems currently coming to market, said Eguana.
Residential consumers can use the battery to store electricity from solar and use it during evening hours, or it can be used by fleet aggregators to provide utility grid management services including voltage control, frequency regulation, demand response and load balancing, or as a retrofit to solar PV installations already in place.
The race is on to develop a residential-use battery pack with Tesla Motors in mid-February saying it was six months' away from launching a home energy storage system.
Tesla said it had finished the design of a pack powerful enough to electrify a house and “we are going to unveil the Tesla home battery, the consumer battery that would be for use in people’s houses or businesses fairly soon,” said the company’s CEO Elon Musk.
