About Sustainable Energy:

Sustainable Energy (www.sustainableenergy.com) 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 SUNERGY_TM 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) 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.
