Wind Turbines and Towers
Kestrel wind turbines are among the best performing and most efficient wind power systems. Kestrel's strict adherence to quality standards and continuous development of Kestrel technology has resulted in a line of high quality, quiet, powerful, and robust machines in 600, 800, 1000 and 3000 Watts rated power that are both reliable and cost effective. All Kestrel turbines feature Full Axial Flux Discoid Technology, for high efficiency and increased energy production in lower wind areas.
All models use patented pitch control, allowing blades to maintain rated output in excess wind speeds and optimizing overall power production.
Energy may be harvested at any different wind speed exceeding cut-in speed and rated output is maintained through rotor turbulence and pitch control in high winds. Energy output is intrinsically linked to your site's wind distribution, topology and altitude as well as tower height and the height of trees or structures in the area.

Certifications: CSA approved to UL and CSA specifications*
-
Quiet Operation**
*Air 30 and Air 40
**Air 40 and Air Breeze blades are specifically designed for low sound emissions
e160i 600W Kestrel
4.3 mph cut in wind speed, 29 mph rated wind speed
Compact and virtually silent, the e160i uses 5 fiberglass blades with a 5.24-foot rotor diameter, making it the smallest model on our floor. Used around the world and in Alaska to power railway switches, public lighting, communication towers, and for education. Appropriate for battery charging, grid tie or hybrid systems, the output voltage can range from 12 to 200 Vdc. Tower top mass is 66 lbs. Monopole used with a charge or voltage limiter.
e300i 1000W Kestrel
5.6 mph cut in wind speed, 24.6 mph rated wind speed
The e300i is the next generation of 1000w small wind turbines, used around the world to power water pumps, telecom sites, resistance heating, battery charging and grid tie or hybrid systems. The e300i uses 3 fiberglass blades with a 9.84 ft rotor diameter. Appropriate for water pumping, heat production, battery charging, grid tie or hybrid systems, the output voltage can range from 12,24,36,48,110 and 200 Vdc. Tower top mass is 165 lbs. Monopole used with a charge or voltage limiter.
Primus Air 30
small turbine that is fitted out like the mega-watt class turbines
The Air 30 builds upon what has made AIR the world's #1 selling small wind turbine. The new technology used in the Air 30 was only previously found in mega-watt-class wind turbines.
The AIR 30 uses a new microprocessor based technology that results in an increase in performance, battery charging capability, and reliability. Additionally, "flutter" noise from the machine has been reduced.
The controller allows for peak-power tracking of the wind by optimizing the alternator's output on all points of the cubic curve and efficiently delivers the energy to the battery. The turbine's smart controller allows it to actually control blade rotation speed thus eliminating the buzzing noise commonly found with most small wind turbines.
Primus Air 40
All NEW!!!
Super Efficient and Quiet
e230i 800W Kestrel
5.6 mph cut in wind speed, 28 mph rated wind speed
The e230i uses 3 fiberglass blades with a rotor diameter of 7.54 feet. The e230i is often used in rural installations where there is no grid tie available. Also appropriate for battery charging, grid tie or hybrid systems, the output voltage can range from 12, 24, 36, 48, 110 and 200 Vdc. Monopole tower top mass is 99 lbs. and can use either a charge or voltage limiter.
The all-new Air 40. Quieter, more efficient, and precision engineered to deliver more energy at lower wind speeds than any other wind generator in its class. Air Breeze is the next generation of Air turbines with more than 100,000 units sold in 120 countries, the world's most popular small wind turbine.
The AIR 40 uses a new microprocessor based technology that results in an increase in performance, battery charging capability, and reliability. Additionally, "flutter" noise from the machine has been reduced.
The controller allows for peak-power tracking of the wind by optimizing the alternator's output on all points of the cubic curve and efficiently delivers the energy to the battery. The turbine's smart controller allows it to actually control blade rotation speed thus eliminating the buzzing noise commonly found with most small wind turbines.
E400i 3000W Kestrel

The e400i is our largest in-stock turbine and optimizes your renewable energy output and performance through efficiency and size. The e400i uses 3 aerofoil blades with a 13.12-foot rotor diameter. The e400i moderates noise emissions effectively, making it unobtrusive for its size and a reliable method of substantial renewable energy production. The e400i advanced direct drive alternator incorporates three main shaft bearings for longevity and increased reliability. Appropriate for water pumping, repeater stations, heat production, small wind farm installations, battery charging, grid tie or hybrid systems, the output voltage can range from 48, 200 and 300 Vdc. Used around the world to generate dedicated power for housing, community and health centers not connected to the national grid. Tower top mass is 331 lbs. Used with a tripod tower and a charge-only controller.
POWER TIP!
Why Off Grid Systems Should Include Both Solar AND Wind
-
Wind speeds are highest during the winter months when solar resources are at their minimum
-
Air density is highest in winter maximizing wind power production
-
Wind provides power during inclement weather when sunshine is not present
-
Wind provides power at night
Excel 1, 6, and 10
Excel 1
Designed for high reliability
With a rotor diameter of 2.5 meters (8.2 ft) and a peak output spiking over 2,000 watts the Excel 1 is a perfect system upgrade for current owners of solar-only off-grid systems along with light telecom and other high reliability off grid applications. Following the same simple design as the larger Excel turbines, the Excel 1 has been a favorite tool for experienced renewable energy practitioners for over a decade. The recently updated version incorporates the acclaimed American made MidNite Solar Classic 250 multi-voltage charge controller. This allows the unit to charge 12V-48V nominal battery banks. A higher voltage stator reduces the required conductor sizing for wire runs making installation more affordable, and a newly incorporated disconnect box makes inspections as simple as a flick of a switch. Marine-grade corrosion protection has also been added as a standard feature. BWC offers tilt-up tower solutions in heights ranging from 60’ – 100’. Add capacity and reliability to your off-grid system with this powerful yet simple solution.
Excel 6
An Exceptional Performer
The new Bergey Excel 6 is ideal for smaller and more efficient homes, farms, and small businesses. Its extra large rotor and ultra low cut-in wind speed give it exceptional performance, out producing all other turbines in its class.
Excel 10
Designed for high reliability and low maintenance
The BWC Excel 10 is a modern 7 meter (23 ft) diameter, 10 kW wind turbine designed for high reliability, low maintenance, and automatic operation in adverse weather conditions.
