ZBB Energy Corporation Announces Order From SEI Group Inc.

MILWAUKEE--(Business Wire)--
ZBB Energy Corporation (NYSE AMEX:ZBB) today announced that it has received a
new order for its ZESS 50 unit with a ZESS POWR PECC to SEI Group Inc. of
Huntsville, AL for a US government facility as a demonstration site.

This fully integrated ZESS power system will be used in an on-grid configuration
with Photovoltaic (PV) renewable energy generation inputs for use to provide
both daytime and nighttime power to the host building`s lighting system. The
ZESS POWR PECC system will control energy and power inputs, direct energy flows
to and from energy storage, regulate clean power to the lighting system and when
available, send excess energy to the site`s larger electrical distribution
system.

ZBB`s Vice President Sales and Marketing, Mr. Kevin Dennis said, "This project
is the initial 24hr photovoltaic powered system for a US government facility,
that firmly places energy storage as the cornerstone for an integrated,
renewable energy system that not only can shift energy outputs across the daily
use and generation cycle associated with PV, but has the capabilities to send
surplus power to either storage or to the grid, based on time of day or other
priorities. Though this is only the initial demonstration system, the
architecture used by SEI for this project is readily scaled up to much larger
systems capable of producing, storing and managing renewable energy for entire
sites."

Mr. Mark Kelly, Vice President / Program Manager for the Energy Technologies
group at SEI said, "ZBB`s system approach for integrating next-generation
zinc-bromide energy storage units and renewable energy made this a
straight-forward design and implementation for our engineering team that wasn`t
available previously. The ZESS POWR system will make renewable energy more
stable and valuable as a generation source."
