ZBB Energy Corporation Received ETL Certification to UL 1741 for Its ZBB EnerSection Power & Energy Control Center

ZBB EnerSection Inverter Module Complies With Both UL and IEEE Standards for Grid Connection

MILWAUKEE, WI--(Marketwire - Jan 12, 2012) - ZBB Energy Corporation (NYSE Amex: ZBB), the leading developer of intelligent, renewable energy power platforms, announced today it has received the ETL listing to UL 1741 certification from Intertek Testing Services for its 25kW grid-tie inverter module of the ZBB EnerSectionpower and energy control center. The UL 1741 certification incorporates IEEE 1547 requirements for the interconnection of distributed generation (DG) resources. This certification signifies that the inverter module of the ZBB EnerSection meets all of the product safety standards for connection to a utility power grid anywhere in the United States or other countries where UL standards are accepted.

The ZBB EnerSection is a modular, controllable, bi-directional, hybrid power conversion platform that intelligently integrates, manages and optimizes multiple renewable and/or conventional power generation sources simultaneously while incorporating energy storage. Its configurable architecture integrates multiple AC and DC power generation sources discreetly with one or multiple types of energy storage units with any combination of utility grid-tie inverters, stand-alone inverters for off-grid AC power and/or DC outputs to provide DC power.

On August 30, 2011, ZBB received U.S. patent #8,008,808 "Method and apparatus for controlling a hybrid power system," relating to the Company's ZBB EnerSection power and energy control center. In addition to receiving certification for the 25kW ZBB EnerSection inverter, the company is currently working on UL 1741 certification for its 60kW and 125kW grid-tie units. With a full range of ETL Listed inverters, the ZBB EnerSection can be modularly configured to various power ratings.

"The ETL certification is a great milestone for our company. The combination of certified grid-tie inverter electronics and our patented DC based ZBB EnerSection offer customers in the distributed grid a turn-key intelligent system. The strategic design wins in our backlog have been driven by the benefits of this offering. ZBB is uniquely positioned to deliver integrated storage solutions in markets where certification is required for grid interconnected systems," said Eric Apfelbach, President and CEO of ZBB Energy. "We can now begin shipping product from our backlog to customers who've been waiting for ETL grid-tie capabilities."
