Enphase Energy introduced its Enphase AC Battery, an advanced energy storage solution with a modular, plug-and-play storage device fully integrated with the just-introduced Enphase Energy Management System. As part of the AC Battery rollout, Enphase has engaged several installation companies for pilot projects, including Lennar Homes, Hawaii Energy Connection and Vivint Solar in the U.S.; Pretty Green Energy, CJ Solar and Domuneo in Europe; and Metro Solar in Australia. The Enphase AC battery, equipped with the S-series microinverter, will provide 1.2 KWh of energy storage and 275W/550W power-output. The Enphase Energy Management System, including the Enphase AC Battery, will be available through authorized distribution channels in the second half of 2015.
