This machine has a nominal power output of 400 W at 12.5 m/sec.  Electricity  production  starts at 2.7 m/sec. Output  voltage  can  be 12/24 V.  It  is  a  three-blade model  with  a rigid  construction.  Blades can  bend  to hold excessive wind pressure.
Compact,  easy  to  mount.  Has  brushless  permanent magnet alternator,  aluminum cast body,  carbon matrix rotor blades. Mounts to a 1.5” inside diameter schedule 40 steel pipe (about 1.9” O.D.). 46” rotor diameter.

With  a nominal power output  of 900 W at   12.5  m/sec,    electricity   production starts at 3.4 m/sec.  This  is a three-blade wind turbine.  A  patented angle governor protects  the  machine  against  excessive wind.
Whisper Wind Generators are fairly quiet. The blades on all models are injection-molded fiber reinforced. All models use a direct drive, brush-less, permanent magnet 3-phase alternator for high power and low cost.

This machine has a nominal power output of 1000 W at 10.5 m/sec, with a threshold wind speed of 3.1 m/sec. This is also a three blade wind turbine with the same wind protection system as H-40.
Unregulated AC power from wind generator is sent to be rectified to DC at the control box which is used for charging batteries. Sealed bearings are permanently lubricated for low maintenance. Frame is stainless steel or cast aluminum.
