SunMizer(TM) Solar DC Power Optimizer Receives UL and GS S1 Safety Certifications

Certification to US and EU Safety Standards Performed by TUV Rheinland of North America

PETALUMA, California, January 11 - The Solar Division of Xandex Inc. announced today that its new
SunMizer(TM) DC Power Optimizer for solar panels has been certified to both
United States and European safety standards by TUV Rheinland of North
America.

TUV Rheinland of North America Inc., a Nationally Recognized Test
Laboratory (NRTL), has certified SunMizer to the Underwriters Laboratories
(UL) 1741 safety standard. UL 1741 is the US safety standard for inverters,
converters, charge controllers, and interconnection system equipment (ISE)
intended for use in stand-alone or utility-interactive (grid-connected) solar
power systems.

The TUV Rheinland GS S1 certificate is presented to manufacturers that
demonstrate full compliance with the GPSG (German equipment safety law) and
also demonstrate compliance to the Low Voltage Directive (LVD) required for
CE mark labeling.

Xandex chose TUV Rheinland of North America to perform SunMizer safety
certification testing because they provide a single-source entry to both the
US and European markets by combining test activities into a single program
that shortens time to market and reduces overall certification costs.

"Our close collaboration with TUV Rheinland resulted in an efficient and
timely process, from initial Design Review through final product testing,"
states Jeff Muchow, VP of Engineering and Quality at Xandex. "The process was
thorough, ensuring SunMizer is a safe and effective product for both the
American and European markets."

About SunMizer

SunMizer is a DC power optimizer for use in solar power installations
that experience power loss due to shade. When selectively installed only on
the shaded panels in a solar array, SunMizer can recover over 50% of system
level power loss caused by the partially shaded panels. SunMizer is
immediately available in the US and will be available Q2 2010 in the EU
through leading US and European solar equipment distributors. For more
