e150 (600W)

The Kestrel e150 has a large diameter 240 mm (9.45”) alternator driven by a 1.5 meter (4.92') 6 blade, self-stalling rotor that, along with the shunt regulator, eliminates the need for yaw and/or electronic shutdown in high winds. This is an ideal machine for telecoms, military, remote cabins and other similar applications. The 600 is quickly replacing many under-performing and poorly backed turbines in the 300 to 900 Watt range on the African continent. It is available in 12, 24, 48 and 200VDC, user-adjustable outputs.

e220 (800W)

The Kestrel e220 employs a unique variable-pitch 2.2 meter (7.2') fiberglass rotor driving a discoid axial flux alternator, which allows for high low wind efficiency and full rated power output in all winds at or above 12 M/S (25.76 MPH) without energy-robbing yawing or electronic shutdown. Because of its large swept area and high efficiency, the e220 is a great choice for low wind sites, yet is equally at home in high winds. Suggested uses include battery charging, direct water pumping, resistance heating and utility inter-tie (with an approved inverter).

Specifications

• Rated Output:  800W
• Maximum Power:  850W at 13ms -1
• Rated Wind Speed:  12.5ms -1
• Cut in Windspeed: 2.5ms -1
• Rotor Diameter :  2.2m
• Number of Blades:  3
• Blade Material:  Fiber glass
• Tower Top Mass:  45kg
• Tower Height:  9-15m
• Tower Type:  Scissor or Guyed
• Overspeed Protection:  Pitch Control
• Generator Type:  Permanent-magnet Axial flux brushless
• Output Voltage:  12, 24, 36*,48, 110* and 200 Vdc
• Controller Type:  Charge or Dump

e300i (1KW)

The next generation e300 i exemplifies the beauty of sophisticated aerodynamic design. The e300 i is compact and unobtrusive making it suitable for urban living. The e300 i is suitable in all wind classes and has a low start-up torque that requires minimal wind to generate energy.  Modern living demands more applications that require energy usage. Every feature of the e300 i optimizes renewable energy generation, increasing energy efficiency and cost saving.

The three aerofoil blades, with a diameter of 3.0m, are managed by a passive pitch control system that allows the e300 i to continuously generate usable energy in wind speeds that exceed rated wind speed.  This is one of the factors that contribute to the e300 i being one of the best machines in its class in terms of overall energy harvest on an annualized basis. The e300 i advanced design moderates noise emissions effectively, making it an inconspicuous power source in all installations and environments.

Specifications

• Rated Output:  1000W
• Maximum Power:  1150W at 12ms -1
• Rated Wind Speed:  11ms -1
• Cut in Windspeed:  2.5ms -1
• Rotor Diameter:  3m
• Number of Blades:  3
