Marine version of the AIR-X. Powder coated housing and sealed against the salt air.
Redesigned in 2001, the AIR-X now has technology that was previously typically only found in state-of-the-art mega-watt-class wind turbines. It incorporates new microprocessor based technology that results in improved battery charging capability, greater reliability and a reduction in the "flutter" noise under high winds.
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 energy to the battery. The turbines smart controller allows it to actually control blade rotation speed thus eliminating the buzzing noise commonly found with most small wind turbines.
AIR-X's 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.
Improved battery charging now allows safe charging of battery banks from 25 to 25,000 amp hour or higher.
