Toronto, Ontario – October 5, 2011 Sustainable Energy Technology Ltd. (TSX-V: STG) ("Sustainable Energy") today announced that it will roll out its new "PARALEX" line of inverters for residential small commercial and institutional rooftop solar PV systems at Solar Power International in Dallas, Texas October 17 2011. PARALEX is reporting peak efficiencies above 97% and 99.8% product reliability.

PARALEX targets an emerging demand for "parallel" solar in higher power ratings which micro-inverters have not been able to meet on a cost effective basis. Even industry giants such as SMA, which reportedly will unveil its own micro-inverter this month, is said to be telling its customers that micro-inverters will not be cost competitive with leading string inverters above 2 kilowatts notwithstanding the performance gains (per: Green Tech Media September 19, 2011).

PARALEX delivers these same performance gains and design flexibility at a cost that is competitive with leading string inverters. PARALEX is the industry's only high efficiency string inverter to enable a parallel system design. The results are simple flexible installations in higher power ratings, which easily accommodate variations in rooftop orientations, partial shading, and increasingly complex fire codes.

"According to IMS Research this will be an annual market worth $1.3 billion by 2015 and the patented PARALEX technology has the potential to take a sizeable share," said Michael Carten, CEO of Sustainable Energy. "Early responses to PARALEX from experienced US and German installers have been very positive. It is clear that the market is looking for a cost effective solution which will accommodate less than ideal conditions. especially in Germany where ideal sites are quickly disappearing."

About Sustainable Energy:
Sustainable Energy (www.SustainableEnergy.com) is a Canadian solar inverter company which supplies Canada, the U.S. and Europe. The Company's patented inverter technologies are a breakthrough in power inverter design and capabilities for all forms of distributed generation and smart grid applications. The PARALEX inverter is the industry's only grid-interactive solar inverter which enables a "parallel" solar PV system architecture in higher power ratings at a cost and serviceability factor that is comparable to conventional inverters in the market. The benefits of parallel solar are: (i) 5% - 25% higher total system power output; (ii) a better fill factor enabling better coverage of available space; (iii) a simplified system design and installation; and (iv) the safety of extra low operating voltages which ensures the safety of building maintenance personnel, first responders, and tradesmen who may accidentally come into contact with system wiring. Sustainable Energy's technologies are the subject of multiple patents issued by and pending with the Canadian and US Patent Offices.
