ZBB Energy Corporation Receives ETL Listing to UL 1741 Standard for 125 kW Grid-Tie Inverter Module

Exceeds Safety Standards Globally Recognized by Utilities

MILWAUKEE, WI--(Marketwire - Sep 4, 2012) - ZBB Energy Corporation (NYSE MKT: ZBB), a leading developer of intelligent, renewable energy power platforms, today announced it has received Edison Testing Laboratory (ETL) listing to Underwriters Laboratories (UL) 1741 standard for its 125 kW grid-tie inverter module of the ZBB EnerSection™ power and energy control center. The 125 kW grid-tie inverter is a device that allows stored direct current (DC) energy to be converted to alternating current (AC) energy and put back on the grid.

The ETL listing to test to UL 1741 standard was performed by Intertek Testing Services. The UL 1741 standard incorporates Institute of Electrical and Electronics Engineers (IEEE) 1547 requirements for the interconnection of distributed generation (DG) resources. This certification signifies that the 125 kW inverter module of the ZBB EnerSection meets, or exceeds, 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, similar to the ETL certification of the Company's 25 kW inverter modules received earlier this year.

"We recently announced and field labeled two ETL 125 kW inverters in Chicago which are currently in service for the Illinois Institute of Technology's micro grid project. This final certification is a significant milestone because it allows us to manufacture, test and certify that all 125 kW units shipped from our facility are ETL listed to UL 1741," said Eric C. Apfelbach, President and CEO of ZBB Energy. "This certification allows us to ship our 125 kW inverters to projects in China, Hawaii and North America."

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.

Based upon the Company's current market assessment of required ratings from customers of grid-tie inverters, it will focus on the 25 kW and 125 kW inverter products and schedule a later date for introduction of the 60 kW inverter when a market need is firmly established.
