WIND GENERATORS

SouthWest Windpower
For 20 years, Southwest Windpower has been bringing low-cost, reliable wind energy to the world. As the world's largest producer of small wind generators, we've pioneered new technologies to make renewable energy simple.

Skystream 3.7™
The latest development is the Skystream 3.7, which was developed jointly with the U.S. Department of Energy. It's the first compact, user-friendly, all-inclusive wind generator designed to power utility-connected homes and businesses. Quiet, inexpensive energy is closer than you think.

The Skystream 3.7™ is a new generation residential wind generator that hooks up to your your home to reduce or eliminate your monthly electrical bill. It’s the first all-inclusive wind generator (with controls and inverter built in) designed to provide quiet, clean electricity in very low winds. This makes Skystream ideal for residential homes and small businesses.

The Skystream 3.7 is a down-wind (wind hits the blades on the downwind side of the tower) direct drive (gearless or no transmission) permanent magnet wind generator. Skystream 3.7 uses an innovative 3.7m rotor and produces approximately 300 kWh per month at a typical UK 5m/s AMWS site.

A visually aesthetic shape played a key role in the design to show that a wind generator is not only a clean source of energy but pleasing to the eye.

Rated Capacity: 1.8 KW
Rotor: 12 feet (3.72 m); 50-325 RPM
Interconnection: Utility connected or battery charging
Alternator: Gearless, permanent magnet brushless
Voltage Output: 240 VAC (Optional 208 VAC)
Estimated Energy Production: 400 KWh per month at 12 MPH (5.4 m/s)
Weight: 170 pounds (77 kg)
Tower: Towers from 34-70 feet (10.4-21.3 m) are available; height is dependent by site

SKYSTREAM 3.7™ recently voted one of the "Top 10 Green Building Products 2007" in Supplement to Sustainable Industries, August 2007 Issue No. 55

Whisper 100 900w
Formerly the Whisper H40, the Whisper 100 has been updated for 2005 with new features and added flexibility for your renewable energy system.

Now, any Whisper 100 can have its voltage changed, 12-48V DC, within a few minutes in the field. The Whisper 100 is designed to operate in a site with medium to high wind speed averages of 12 mph, 5.4 m/s, and greater.

The 100 provides 100+ kWh per month, 3.4 kWh per day, in a 12 mph average wind. Worried about noise? The Whisper 100 is one of the quietest wind turbines ever tested by the National Renewable Energy Labs. Click on the link above for a copy of the noise data report.

Whisper 200 1kW
Formerly the Whisper H80, the Whisper 200 has been updated for 2005 with new features and added flexibility for your renewable energy system. Now, any Whisper 200 can have its voltage changed, 12-48V DC, within a few minutes in the field.

The Whisper 200 is designed to operate in a site with low to medium speed averages of 8 mph, 3.6 m/s, and greater. The 200 provides 200+ kWh per month, 3.4 kWh per day, in a 12 mph average wind.

The Whisper 200 does produce more noise than it's 100 counterpart, but it does produce almost twice the power.

Air X Marine, 12V
Improved energy capture in low winds. The latest evolution in small wind turbines, the AIR-X Marine uses a microprocessor to control the RPM and to provide pulse-width modulating (PWM) control for optimal battery charging. The result is a much quieter, more efficient, and a better battery charging routine. AIR-X electronics are programmed to charge the battery at different charging rates, from “bulk” charging (high amps), “taper” charging (moderate amps, high voltage) to “float” charge (low amps, moderate voltage).

AIR-X's programmed charged control system is also excellent for newer boat power systems using more advanced batteries which require more sensitive charge management.

The PWM control provided by the microprocessor allows battery charging to begin at 500 RPM as compared to the 850 RPM in previous AIR turbines. This enables improved energy capture in low winds (7 - 12 mph).

Charge Output: 33.3A@28mph
Min. Windspeed: 7mph
Overspeed Protection: Auto-brake protection, high wind speed mode
Output Regulation: Internal PWM microprocessor, multi-stage charging
Blade Span: 46"
Blade Material: Carbon fiber composite
Case Material: Aluminum
Case Dimensions: 26.6"L x 11.25"H
Weight: 13lb.
