Southwest Windpower Whisper

Years of reliable operation by thousands of customers have made the Whisper 100, 200 and 500 the number one selling wind turbines in their class. With thousands in the field, the Whisper 100 has become the standard for remote homes, telecom sites and rural developing projects for moderate to extreme environments. Assuming a 12 mph (5.4 m/s) average wind, a Whisper 100 will produce 100 kWh per month for your batteries.

The Whisper 200 is a versatile design that is used in many applications, from remote homes to water pumping. A high voltage model is available for transmission over long distances and for grid-connected systems. There is a charge controller included with every Whisper 100 and 200.

The Whisper 500 is a two bladed turbine incorporating the patented side furling design that optimizes output at any wind speed. Assuming a 12 mph (5.4 m/s) wind, a Whisper 500 will produce as much as 500 kWh per month; enough energy to power the average Californian home. There is an EZ-Wire Controller included with every Whisper 500. This controller includes a diversion load to ensure quiet, safe operation of your wind turbine when the batteries are charged.

Specifications:

• Over speed Protection - Side-furling
• Warranty - 5 year limited warranty
• Survival Wind Speed - 120 mph (55 m/s)
• New Bushing: Provides superior reliability and smoother operation
• Patented Side Furling: This new patented side furling protects the turbine in high winds by turning the alternator and blades out of the wind, reducing exposure. Unlike other wind turbines that lose as much as 80 % of their output when furled, the Whisper achieves maximum output in any wind.
• Adjustable Voltage: The Whisper’s voltage is adjustable to grow with your RE system.
• Four Bearing Spindle: The four bearing spindle benefits both efficiency and reliability.
• Upgraded Yaw Shaft: The new upgraded yaw shaft provides an optimal current path.
