Microprocessor-Based Technology

The AIR is by far the world’s number one selling small wind turbine. In late 2001 we introduced an entirely new level of technology previously found only in state-of-the-art mega-watt-class wind turbines.

The Air X incorporates a new microprocessor-based technology that results in increased performance, improved battery charging capability, greater reliability 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 efficiently delivers the energy to the battery. The turbine’s smart controller allows it to actually control blade rotation speed thus eliminating the buzzing noise commonly found with most small wind turbines.

Quieter operation

Previous AIR wind modules relied on their aero-elastic blade design for protection in high winds. This caused a loud flutter noise in winds above 35 mph (16 m/s). The Air X circuit monitors the wind speed and electronically slows the blades as it reaches its rated output preventing it from going into flutter. This results in a much quieter wind turbine. In high winds, the Air X will continue to produce power at a reduced level until the wind decreases, at which point maximum potential output will resume.

Improved Battery Charging

Previous AIR designs required 300-400 amp hour battery banks so the trickle charge of the wind turbine could be adequately absorbed. The Air X 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 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.
