300 Watt Wind Turbines : The wind power generator is the conversion of wind energy into mechanical energy first and electric energy afterwards. This equipment can fully make use of wind power to recharge a battery, and also can the saved energy into ac source alternating current. Without the necessity of fuel, the wind power generator is pollution-free and far away from noise. It is generally applicable to the area which has good condition but is far away from the power grid, or the power grid is not normal. The equipment can supply lighting, the television set, the searchlight, the communication equipment, the power tool and other household appliances.
