Whisper 100™, Whisper 200™, Whisper 500™ and Skystream 3.7 Small Wind Turbines

by Southwest Windpower

Whisper 100™ by Southwest Windpower At a Glance Kilowatt Hours/Month: Rotor Diameter: Voltage: Rated Power: Turbine Controller: Warranty: 100 kWh/mo at 12 mph (5.4 m/s) 7 ft (2.1 m) 12, 24, 36, 48 VDC 900 watts at 28 mph (12.5 m/s) Whisper Charge Controller (included) 5 year limited warranty Monthy Energy Best for moderate to high wind 9 mph (4 m/s) and above Whisper 100 provides dependable energy for remote homes, telecommunications sites and rural applications in moderate to extreme environments. Reliable operation by thousands of customers makes Whisper 100 the top selling small wind turbine in its class. Assuming a 12 mph (5.4 m/s) average wind, a Whisper 100 will produce 100 kWh per month. The Whisper 100 is one of the quietest wind turbines ever tested by the National Renewable Energy Labs. In addition to its patented smooth acting side furling design, the Whisper 100 has a number of new features that make it ideal for any new or existing photovoltaic system. A new four bearing spindle for a smoother operation and longer life. An upgraded Yaw shaft that more efficiently delivers current to your batteries. New bronze bushing and larger diameter furling pin for smoother furling action. New castings that allow easy access to the stator for changing voltage Included with every whisper is our new Whisper Controller.   Whisper 100 Spec Sheet   Brochure | Manual

Whisper 200™ by Southwest Windpower At a Glance Kilowatt Hours/Month: Rotor Diameter: Voltage: Rated Power: Turbine Controller: Warranty: 200 kWh/mo at 12 mph (5.4 m/s) 9 feet (2.7 m) 24, 36, 48 VDC (high voltage avail.) 1000 watts at 26 mph (11.6 m/s) Whisper Charge Controller (included) 5 year limited warranty   Monthy Energy Best for low to moderate wind - 7 mph (3 m/s) and above The versatile Whisper 200 powers applications from remote homes to water pumping. Get the most out of the wind with a larger swept area. The Whisper 200’s 9-foot (2.7 m) blade has almost twice the swept area of the Whisper 100, yielding twice the energy. A high voltage model is available for transmission over long distances. The Whisper 200 does produce more sound than it’s 100 counterpart, but it does produce almost twice the power. In addition to its patented smooth acting side furling design, the Whisper 200 has a number of new features that make it ideal for any new or existing photovotaic system: A new four bearing spindle for a smoother operation and longer life An upgraded Yaw shaft that more efficiently delivers current to your batteries New bronze bushing and larger diameter furling pin for smoother furling action New castings that allow easy access to the stator for changing voltage.

Whisper 500™ by Southwest Windpower At a Glance Kilowatt Hours/Month: Rotor Diameter: Voltage: Rated Power: Turbine Controller: Warranty: 538 kWh/mo at 12 mph (5.4 m/s) 15 feet (4.5 m) 24, 36, 48 VDC (high voltage avail.) 3000 watts at 24 mph (10.5 m/s) Whisper Charge Controller (included) 5 year limited warranty Monthly Energy Whisper 500: Serious Energy for Remote Locations The robust Whisper 500 delivers serious energy for your remote power needs. The Whisper 500 performs well in harsh, high wind environments with it’s two-bladed, fiberglass-reinforced design. Patented side furling overspeed protection 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. That is enough energy to power the about half the needs of an average home. Maximum Output in Any Wind Exclusive to the Whisper, the side-furling angle-governor protects the turbine in high winds by turning the alternator and blades out of the wind, reducing turbine exposure. This angle-governor lets the Whisper 500 continue to safely spin and deliver energy even in high winds. Whisper 500 Spec Sheet
