Wind Turbines and Towers

Whisper 500

The Whisper 500 is perfect for a small home or farm. It has two-bladed 4.5 meter (15 ft.) diameter rotor. The 500 is a best buy for ample power in medium winds. Its rated power is 3,000 watts. Both Stock No. 450476 and 450477 include the Whisper 500 Controller with a power monitor which also accepts 1600 watts of photovoltaic panels. The stock No. 450477 Whisper 500 High Voltage Turbine also includes a step-down transformer for 220 volt 3 phase power transmission, allowing long wire runs up to 3 miles!

The Whisper 500 is suitable for larger power requirements. Even in marginal wind, the 500 generates more than enough power for comfortable but energy concious living. Water pumping, battery charging, utility intertie, telecommunications, and remote village power are all applications for the 500. The available high voltage option includes a transformer for wire runs up to 3 miles. Not only does this allow installation of the turbine in the best location, but it minimizes power losses and reduces downlead wire costs dramatically.

The Whisper 500 charge controller included with every Whisper 500 can monitor and control current from wind, solar, and microhydro generation. Excess power is diverted through a resistor network that can be used for area heating. A diversion load for water preheating is optional. Each input has its own circuit breaker, plus a panel mounted turbine stop switch. There is an output for direct DC loads, and float voltage is adjustable for different battery types. Large terminal lugs are included for easy wiring. An external brake switch is also included in a rainproof UL listed enclosure.

The Whisper 500 features the patented Angle-Furl Governor that all turbines in the Whisper line share. In high winds the Whisper will quietly furl its blades to protect itself from damage. Unlike other turbines that lose 80% of their output, the Whisper will maintain its power output while furling in all winds.

Best of all, the Whisper is not for the novice - please download the manual from www.windenergy.com to help with your decision. Windstream Power LLC can provide towers and all necessary system components, installation services and site visits (in Vermont) to accompany the included comprehensive installation manual.
