SunMizer(TM) DC Power Optimizer Achieves 500+ Year MTBF Estimate

Simple design offers extreme reliability

PETALUMA, Calif., Oct. 28 /PRNewswire/ -- Xandex Solar today announced its new
SunMizer(TM) DC Power Optimizer has completed in-house and Ops A La Carte LLC
reliability modeling and testing. The reliability modeling concludes that
SunMizer(TM) has an expected Mean Time Between Failures (MTBF) of more than
500 years.

Xandex Inc, leveraging more than 28 years of experience designing high
quality, high technology products, conducted electrical performance,
environmental qualification and field tests to ensure SunMizer(TM) performance
over the range of operating conditions exceeds the expected life of the
product. "The SunMizer(TM) design and quality team's number one focus is
reliability," stated Xandex VP of Engineering and Quality, Jeff Muchow. "Our
team hit the mark by maintaining low component count and using components
designed for use in demanding environments. In addition to extensive testing
in the Xandex Reliability Lab, we knew we wanted to engage in Highly
Accelerated Life Testing (HALT) to improve product reliability and support
implementation of Highly Accelerated Stress Screening (HASS) in production;
our partner, Ops A La Carte was able to supply this and much more."

Ops A La Carte LLC, leveraging experience of reliability testing more than 500
products worked with Xandex to successfully execute HALT of the SunMizer(TM)
product and develop a HASS protocol for production. "The Ops A La Carte team
was able to integrate and collaborate with the Xandex team on their schedule
and provide traditional reliability models," Mike Silverman, Managing Partner
for Ops A La Carte stated. "In addition, our proprietary tools and patented
reliability estimation methods were used to ensure SunMizer(TM) operates
beyond its expected life, critical for a product with a generous warranty."
