It is more important when conventional energy sources are fastly depleted and energy demand in world particularly in developing countries is increasing exponentially with technological development. Among all renewable sources the solar , wind and bio energy which is in abundance and pollution free, widely distributed, freely available and covering wide range of application is becoming more popular so we develop a solar, wind and bio integration system with efficient power management. In this project we improve the efficiency of solar, wind bio system by integrating them for maximum utilization of energy. We design a system to store energy in batteries and to get direct power in Ac and Dc source. Our system is microcontroller based system which automatically switches power to battery or to load depending on the voltage of the source. Major components LCD, Inverters, DC generator, Relay, Transistors.en-USEnergyWindSolarThesis
