Sustainable Energy Unveils Second Generation SUNERGY Power Inverter in Hamburg, Germany

Extra low voltage inverter achieves maximum return on investment for rooftop applications and ensures safety for commercial and public sector buildings

Hamburg, Germany - September 22, 2009 - Sustainable Energy Technologies Ltd (TSX VENTURE:STG) ("Sustainable Energy") today unveiled its second generation SUNERGY extra low voltage power inverter at the PV SEC Conference and Exhibition in Hamburg, Germany. This next-generation inverter is now commercially available to power solar rooftop applications for alliance partners, distributors and thin film and crystalline manufacturers looking to develop high yield, low cost systems and solutions for the commercial and institutional market.

SUNERGY breaks the traditional inverter mold by offering high efficiency power conversion at safe voltages. SUNERGY facilitates wiring of solar panels in parallel, improving performance and flexibility while simplifying system design. With SUNERGY, solar rooftop power systems harvest the full power from each module without adding costly, complex on-module electronics. Solar power systems based on SUNERGY inverters offer the following key benefits:

Higher energy yield per rated kW by eliminating mismatch losses

Elimination of hazardous voltages for the safest PV systems

Easy design and installation that achieves 100% coverage for any surface by eliminating string sizing requirements

Low cost of ownership through reliable low voltage commercial components that extend the life of each module

The SUNERGY second generation inverter technology builds on the patented core technologies, electronic circuits and software control algorithms that have been tested and proven in the field over the past two years. The new platform introduces a unique modular design philosophy that enables very high volume manufacturing of a single power electronics module to support multiple product applications and power ratings, ranging from 2.5kW to 20kW.

SUNERGY is available now for European customers. Sustainable Energy intends to release the North American version upon receipt of UL 1741 certification by the Canadian Standards Agency.

About Sustainable Energy: Sustainable Energy ( is changing the way the world installs solar power through PARALEX a unique line of solar energy products and systems for commercial and public sector markets. PARALEX is based on a patented extra low voltage high yield inverter, with both crystalline and thin film PV modules, which enables a parallel architecture to increase total system yields while also addressing emerging safety concerns. PARALEX achieves higher energy yields and operates at intrinsically safe voltages as well as enabling simpler more flexible design that improves module coverage of any rooftop. The result is the lowest cost per kilowatt hour for maximum return on invested capital.

Sustainable Energy's technologies are the subject of multiple patents issued by the US Patent Office with further patents pending.

SolarEdge Technologies - EV Charging Single Phase Inverter

SolarEdge Technologies - EV Charging Single Phase Inverter

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power SolarEdge's EV charging single phase inverter offers homeowners the ability to charge electric vehicles up to six times faster than a standard Level 1 charger through an innovative solar boost mode that utilizes grid and PV charging simultaneously. This product is the world's first EV charger with an integrated PV inverter. Reducing the hassle of installing separately a standalone EV charger and a PV inverter, the EV charging inverter eliminates the need for additional wiring, conduit and a breaker installation. By installing an EV charger that is integrated with an inverter, no additional dedicated circuit breaker is needed, saving space and ruling out a potential upgrade to the main distribution panel. Whether you own an EV now or just want to be EV-ready, future-proof your home with SolarEdge.
