Wind generator is an electromechanical device which can transform wind energy to mechanical energy, then transforms into the electrical energy. Using wind power generation, it can save electrical energy to the battery charging, also can transform electrical energy to alternating current with output 220V/50Hz, 120V/60Hz, 230V/50Hz. Wind generator with no fuel, no pollution, no noise is a good energy choice for places where is far away from electrical network, or the electrical network not normal. It can supply electricity for air condition, refrigerator, washer, illumination, television, searchlight, communication equipment and many other power tools.
