Wind powered generators are a growing source of renewable energy that can ease the reliance of consumers on traditional power sources. Power harvested from wind produces no pollutants unlike the greenhouse gas emissions that come from the combustion of fossil fuels. Leading the way are wind farms consisting of a series of large wind turbines that each generate megawatts of power. There is also a significant market for smaller, household-size wind turbines that generate less than 10 KW. Prepackaged small wind powered generators can be installed by consumers to reduce or replace the need for connecting to the electrical power grid. The system being designed will be able to power a small home or cabin that is off the main power grid. The system will be able to support a building which consumes about 10 kWh of electricity per day. The wind powered generator will be able to perform at a low rpm range as well as at high wind speeds. The storage system will store enough power for 3 days without sufficient wind. The design consists of a horizontal-axis configuration which has the main rotor shaft and electrical generator at the top of a tower and is pointed directly into the wind. The direction of the wind generator is controlled by a simple wind vane. A 7 ft diameter rotor comprised of 3 blades will turn a permanent magnet alternator mounted horizontally. This will charge a battery bank which stores at least 500 Amp hours at 48 V. A sine wave inverter with a maximum rating of 3000 W will use this battery bank to provide 110 V Root Mean Square (RMS) to the cabin.
