Advanced Storage Products From ZBB Energy to Be Featured at

SHANGHAI, CHINA--(Marketwired - Apr 24, 2015) - ZBB Energy Corporation ( NYSE MKT : ZBB ), a leading developer of innovative energy management solutions serving the commercial and industrial building and utility markets, today announced its products will be featured at the SNEC Power Expo in Shanghai, China. ZBB's China joint venture company, Meineng Energy, will be located in the exhibit of Solar Power, Inc. ("SPI") ( OTCBB : SOPW ), a vertically-integrated photovoltaic ("PV") developer. The conference will be held at the Kerry Hotel Pudong, Shanghai from April 28 to 30, 2015. ZBB and SPI recently announced a proposed partnership including a supply agreement and share purchase agreement, targeted at accelerating global solar penetration through the combination of solar distributed generation and energy storage.

ZBB recently announced a contract for an off-grid 500kWh energy storage and PV power station in the Cayman Islands. PV plus energy storage power stations represent a major growth opportunity in China and elsewhere in the world where grid electricity is either not present or not economical. In March of this year the company achieved critical third party validation of its latest flow battery, the Agile Flow Battery, performed at one of the world's top battery and grid power control products testing facilities, in Beijing, China. The Agile Flow Battery was engineered based upon ZBB's industry leading flow battery design expertise, its breadth of real world application data derived from dozens of installations, and stringent lab testing at ZBB and Meineng Energy. The Agile Flow Battery enables a large amount of energy to be deployed from a relatively small footprint, and is designed for the lowest life cycle cost available for applications requiring more than 2 hours of discharged energy. The Agile Flow Battery technology is well suited to play a vital role in China's planned large-scale adoption of energy storage.
