3.7-kW turbine earns wind industry’s first UL marking

By Paul Dvorak | August 22, 2012

Skystream from the Southwest website

The Skystream 3.7, intended for homes and businesses, is said to be an all-inclusive personal wind generator (built-in controls and inverter)  to work in low winds. It produces up to 400 kWh/mo.

A small wind turbines developer has received the wind industry’s first UL classification for a small wind turbine. The Skystream 3.7 from Southwest Wind power is now certified with the UL 6142 Standard for Small Turbines. This demonstrates that the turbine complies with important safety standards for customers, and it clears the way for installation in any state in the nation that requires this certification. Southwest Wind power manufactures the Skystream, Whisper, and AIR lines of wind turbines.

UL 6142 Safety for Small Wind Turbine Systems was adopted to comply with National Electrical Code electrical safety standards. Manufacturers and installers now have a reliable and predictable path toward successful installation and inspection of small wind systems.

“Achieving UL certification indicates to consumers and inspectors that Southwest Windpower meets the mandatory safety requirements for installation across the U.S.,” said Jeff Smidt, Vice President & General Manager – Energy and Industrial Systems at UL. “The UL mark on the Skystream 3.7 turbine demonstrates our joint commitment to safe, clean energy.”

    Wind turbines are like so fascinating to see, they are like electric fans or pinwheel with giant blades rotating with so much power. I saw this massive wind turbine in the premiere episode of Amazing Race and I was so amazed to see that there are acres of steel pinwheels somewhere in America.

    Really excited to see the UL approval given to the Skystream, but wanted to help clear up a bit of misinformation here. This turbine is not rated at 3.7 kW. 3.7 refers to the rotor diameter of 3.7 meters. The nominal output of this turbine is 2.4 kW, and is only possible at 13 meter per second wind speeds.

    Here is the link to the fact sheet from SouthWest Windpower:

    Its a great machine and I’ve had the pleasure of installing them. I just hate to see a great product that isn’t fairly advertised.

    Cheers.
