Rumble Energy Chooses PARALEX Inverters for Rooftop Projects

Toronto Ontario - October 11, 2011: Sustainable Energy Technologies Ltd. (TSX-V:STG) (“Sustainable Energy”)  and Rumble Energy Inc. ("Rumble Energy") are pleased to announce that Rumble Energy will utilize an additional 140 PARALEX inverters for Solar rooftop projects across Southern Ontario.

We chose PARALEX because it enables the higher yields and greater design flexibility that goes with a parallel system design at a cost that makes sense" said Kelly Rumble President & CEO of Rumble Energy. “The modular service model reduces downtime to maximize my customers return.”

PARALEX is the industry’s only high efficiency string inverter to enable a “parallel” system design for rooftop solar.  PARALEX is made in Ontario with Canadian technology, making it ideal inverter for the Ontario market.

About Sustainable Energy:
Sustainable Energy ( is Canada’s solar inverter company. 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.
