The AIR X Marine is the world’s number one selling small wind turbine for Sailboats. The unit 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.
