ZBB Energy Current Sales Order Backlog Exceeds $6 Million

MILWAUKEE, WI--(Marketwire - May 31, 2011) - ZBB Energy Corporation (NYSE Amex: ZBB), the leading developer of intelligent, renewable energy power platforms, announced today that its power electronics subsidiary, Tier Electronics, LLC, secured a contract valued at more than $500,000 from Synchrotek, Inc. Tier will provide Synchrotek 100 kW inverters for use with variable speed, constant frequency permanent magnet generators to optimize the electrical output of wind turbine technology serving the mid-size wind energy market.

According to Jeff Taylor, President and CEO of Synchrotek, Inc., "Our generator technology, coupled with the Tier inverter, creates a 'matched power system' that allows us to have several output options and features not available with off-the-shelf products. We have the best size/weight to output power ratio available and maintain very high efficiencies. The power system is 'tuned' to take the maximum energy captured by the wind turbine in a variety of wind conditions and convert it to usable electricity, thereby creating a faster payback model for the end customer, benefiting everyone."

"Tier's core strength in rapidly engineering and delivering high-value products aligned with exacting customer requirements is a key component of our growth strategy. Specific to wind products, Tier has proven to be excellent at aligning their capabilities with customer's needs and delivering the best products in the mid-size market segment. This market is seeing accelerating growth and we are thrilled that Synchrotek is putting their trust in us," said Eric Apfelbach, President and CEO of ZBB Energy.
