As the fastest growing energy source in the world, wind energy is now a popular choice for electricity. In areas with sufficient wind, wind power provides the most economical source of green energy. ETA sells turbines by Southwest Windpower, the world leader in small wind turbine manufacturing, sales, and exports. With their advanced and innovative design, they offer the highest power output, the lowest amount of noise, and the most affordable prices on the market. These systems create no waste or pollution, and since the energy comes from the wind, there is never a need to refuel. In addition, their new design also makes them very quiet. Why use a noisy, polluting generator that constantly needs to be refueled? As conventional energy costs continue to increase, so do your savings. This is a long term investment that can increase the value of your property.

The next generation AIR-X!
Southwest Windpower is pleased to introduce the latest in small wind turbines, the AIR-X. The AIR-X builds upon what has made AIR the world's #1 selling small wind turbine with technology previously found only in today's mega-watt class wind turbines.

Much Lower Noise: Previous AIR wind generators relied on their aero-elastic blade design for protection in high winds, causing loud flutter noise in winds above 35 mph (16 m/s). AIR-X’s circuit monitors the wind speed and electronically slows the blades as it reaches 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, then maximum output will resume.

Improved battery charging: Previous designs required 300-400 amp hour battery banks so the trickle charge of the wind turbine could be adequately absorbed. The 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 its full state of charge, the more often the 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 full charge, the blades will slow to an almost complete stop. Only when the battery drops below its voltage set point will it resume charging.

Lower stress design: Power is limited on the input side of the electronics by controlling the torque from the blades. The excess energy no longer has to be dissipated by the electronics resulting in lower stress on the circuit, bearings and other materials.  Stress occurs primarily in high winds, but under these conditions, the electronic stall design reduces the blade speed to 600 rpm, significantly reducing mechanical loading while producing power.

Note: A manual stop switch control is an available option.
