The Turbine Tail kit by Soliex, Inc. turns any GM 10SI/12SI alternator into a simple source of energy for off-grid applications. In addition to the GM alternator purpose built PMG can be mounted as well. Simple hand tools and a rivet gun is all that is needed to assemble the Turbine Tail kit or purchase assembled(some assembly still required). The Turbine Tail is perfect for charging battery banks year round and has features not found in any other turbine of this size:

  • 12v - 5 blade PMA for 12v systems and the 12-48v - 7 blade PMG for 12-48v systems.
  • Corrosion resistant frame and components from 304 SS and 5052-H32 Aluminum.
  • All SS hardware including rivets.
  • Black Acetal (POM) bearings/bushings are virtually maintenance free.
  • Off-set rotor provides whisper quite operation.
  • Hinged tail allows for automatic furling action which eliminates over-speed damage.
  • Full 360° rotation.

Here's how it works:

Looking from the top, the images below depict the Turbine Tail rotor positions at different wind speeds. From left to right the images would indicate no wind or low wind conditions, the center at higher speeds and the right image in a fully furled condition.

Here's what I tested and how:
  • 12v - 1.5Kw permanent magnet generator coupled to a 7 blade rotor of 60.5" (1.54m).
  • 12v - .5Kw permanent magnet alternator (10SI altered with more copper windings from the supplier) coupled to a 5 blade rotor of 59" (1.5m).

The graph below shows the results of testing the prototype Turbine Tail with the the rotor/gen combinations listed above. As can be seen, both turbines begin to produce voltage at a wind speed between 8 and 10 MPH then rise from there until the furling action results in a voltage drop around 35 MPH; this feature alone separates us from other turbine of this size operating in high winds.

In these videos of the prototype Turbine Tail you can see how the rotor rotates about the spindle as it starts to furl in high winds

The schematic below show the basic components needed to complete a system.
