Rumble Energy Selects SUNERGY Inverters to PowerOntario PV Projects


- Rumble’s Commitment to SUNERGY inverters signals strong market acceptance -

Toronto Ontario – April 25, 2011: Sustainable Energy Technologies Ltd (TSX V:”STG”) (“Sustainable Energy”) Canada’s solar inverter manufacturer and Rumble Energy Inc. (“Rumble Energy”), a leading Ontario system integrator, are pleased to announce that the SUNERGY inverter is being utilized in Rumble Energy’s first two FIT installations in Ontario.

Rumble Energy’s projects will really show the versatility and durability of SUNERGY inverters in all applications.


Project Name: Greater Sudbury Utilities 30 kW Dual Axis Test Array Current Status: Completed


Inverter: x6 SUNERGY 5.0 kW 208V

Modules: x48 Conergy 230W, x48 CSI 230W, x48 Trina 230W

Racking: x6 Deger 5000HD

Program: FIT @ $44.2 cents.


Project Name: Undisclosed Current Status: In Construction

Inverter: x16 SUNERGY 5.0 kW 240V

Modules: x432 REC 235W

Racking: Kinetic Angled Rooftop Racking

Program: FIT @ $71.3 cents.



SUNERGY inverters were chosen for these projects based on their cost benefits over other optimization technology, cold weather rating, and high yield parallel advantages and reduced balanced of system costs.


Over the past few years Rumble Energy has built a strong presence in the renewable energy market in Ontario, today they are one of the most recognized names in the industry” said Michael Carten CEO of Sustainable Energy. “These projects are a strong endorsement for the SUNERGY inverter, also for the penetration that our sales team is making. We look forward to working with Rumble Energy on future projects”.

About Sustainable Energy: Sustainable Energy ( is Canada’s solar inverter company. Sustainable Energy’s patented inverter technologies represent a breakthrough in power inverter design and capabilities for all forms of distributed generation and smart grid applications.

The industry’s only grid-interactive low-voltage solar inverter with high power ratings and high conversion efficiencies enables a “parallel” solar PV system architecture at cost that is a fraction of other parallel solar solutions 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) no more complex string calculations simplifies system design and installation; and (iv) extra low operating voltages eliminating the risk of serious injury or death from electrocution for installers or first responders.

Sustainable Energy’s technologies are the subject of multiple patents issued by and pending with the Canadian US and International Patent Offices
