About Sustainable Energy: Sustainable Energy (www.sustainableenergy.com) designs, manufactures and distributes power inverters for grid-connected solar PV systems under the SUNERGYTM trademark. Advanced power inverters are a critical enabler of all modern solar PV power systems converting the direct current ("DC") power output of the solar PV modules into the high quality alternating current ("AC") power required by the power grid. Advanced power inverters also optimize the performance of the solar PV modules and maintain the integrity and safety of the interconnection with the power grid. The SUNERGY inverter is the only inverter platform manufactured today, which enables the game changing parallel system architecture with industry leading efficiencies and with an industry standard cost and form factor. Its PARALEXTM (www.paralexsolar.com) system architecture enables each solar module to operate independently of any other module in the system delivering 5-15% increased energy yield, without the expensive hardware and continuing maintenance cost of micro-inverter products. Every module delivers its maximum power potential while eliminating the string inverter impact of shading, soiling and other real world factors.

The extra low operating voltage of the SUNERGY platform enables a system architecture that is inherently safe and that can be installed and maintained by most building trades without the need for custom design, significantly reducing the installed system cost and increasing investor yields. Sustainable Energy's technologies are the subject of multiple patents issued by and pending with the US Patent and Canadian Patent Offices.
