Alpha SOlar: AIR X Marine wind Turbine

Rotor Diameter: 46" (1.14 meters) Weight: 13 lbs (6 kg) Output: 400 watts at 28 mph (12.5 m/s)
Start up wind speed: 7 mph (3 m/s) Voltage: 12 & 24 VDC Built in regulator.

All of these features are primarily found within the body of the Air X wind turbine. The new microprocessor based speed control results in increased performance, improved battery charging capability and the reduction of “flutter” noise from the machine. The controller allows for peak-power tracking of the wind by optimizing the alternator's output on all points of the cubic curve and then efficiently delivers the energy to the battery. The air x wind turbine’s smart controller allows it to actually control blade rotation speed thus eliminating the buzzing noise commonly found with the AIR 403 and 303 in high winds. Furthermore, a new series of carbon-reinforced blades with a modified pitch angle further increases power production

Introducing the latest evolution in small wind turbines. The AIR X wind turbine builds upon what made AIR the world's #1 selling small wind turbine with new technology previously found only in today's state-of-the-art mega-watt-class wind turbines.

The AIR-X’s charge controller periodically stops charging, reads the battery voltage, compares it to the voltage setting and if the battery is charged, it completely shuts off all current going to the battery. This function is performed within a few milliseconds. The closer the battery is to reaching its full state of charge, the more often the AIR-X’s circuit repeats this action. This means any size battery bank from 25 to 25,000 amp hours or higher can be charged safely. When the battery has reached its charged state, the AIR-X will slow to an almost complete stop. Only when the battery has dropped below its voltage set point will it startup and resume charging. The Benefit: Extended battery life, no overcharging.

Lower stress design: AIR-X limits power on the input side of the electronics by controlling the torque from the blades. The power no longer has to be dissipated by the electronics resulting in lower stress on the circuit, bearings and other materials. Furthermore, stress on wind turbines occurs primarily in high winds. Under these conditions, the electronic stall design reduces the speed to 600 rpm, thereby significantly reducing turbine and tower loading. The Benefit: Greater confidence in turbine operation in high wind conditions without manually operating the stop switch. Note: A manual stop switch control is an available option for the AIR-X.

Improved resistance to the effects of the sun, wind and water: AIR-X marine has vastly improved body preparation and applications of the marine paint during manufacture, ensuring durable powdercoat protection of the body and internal components, even when subjected tot he most extreme sun, wind and water conditions.
