Whisper wind turbines feature a patented side furling angle governor to protect the turbine in
high winds by turning the alternator and blades out of the wind. Other features include field
adjustable voltage, a four bearing spindle for efficiency, upgraded yaw shaft and a new bushing
for smoother operation. Voltage is factory set at 24 Vdc and is adjustable to 12/36/48 Vdc. High
voltage versions of the Whisper 200 and 500 produce 220 Vac transmitting to a step down
transformer that changes it to nominal system voltage (transformer sold separately). High voltage
versions are used in applications where there is a long distance from the turbine to the batteries.
Every Whisper 100 and 200 comes with the Whisper Charge
Controller except for HV and pump models. The SCR-based
shunt type controller, housed in a single unit, is dedicated to wind
only. LED lights indicate regulation operation and Power ON.
Other features include individually rectified phases, battery/turbine
shunt isolation, quiet diversion-powered fan, a large heat sink and
easy access block connectors for turbine and battery wires.
The marine versions, designed for coastal and offshore applications,
feature powder coating for corrosion protection, stainless steel
hardware, marine-grade wire and watertight housings. 5-year warranty.
