Enphase Joins Energy Storage Market With AC Battery


Enphase Energy Inc. says it has entered the energy storage business with its new Enphase AC Battery, a modular, plug-and-play storage device fully integrated with the company's Enphase Energy Management System.

‘Storage is going to be a multibillion-dollar market and will be essential in helping solar gain broader acceptance and higher penetration,’ says Raghu Belur, co-founder and vice president of products and strategic initiatives at Enphase. ‘It provides benefits for the system owner, while also helping with grid stability. We are bringing the same technological innovation to storage that we brought to solar, by pairing our innovative distributed architecture with the best-in-class battery chemistry in the industry."

Based on a distributed architecture, the AC Battery storage solution is designed for residential and commercial applications and allows system owners to store solar energy for nighttime or future use.

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. Furthermore, Enphase has selected ELIIY Power, a Japanese battery manufacturer backed by Daiwa House, as the chemistry provider for Enphase AC Battery.

Enphase says the AC battery, equipped with the S-series microinverter, will provide 1.2 KWh of energy storage and 275 W/550 W power output. The battery can also be monitored and controlled with the Enphase Enlighten software interface. The Enphase Energy Management System, including the Enphase AC Battery, will be available through authorized distribution channels in the second half of 2015.
