The design of hybrid system for small house appliance

Abstract

In recent year the demand for electricity power increase rapidly. Apart from this, there are still having areas that not fully grid connected electricity especially in the rural area. Throughout this matter, certain area had use photovoltaic as electricity source. In Malaysia, not only potential solar energy but also wind energy. The combination of these two sources can produce alternative electrical energy. This project is mainly focused on hybrid of wind and solar energy. The objective of this project is to design a hybrid system for small house appliance usage and develop the battery charger. Since these two sources are not constant, battery is needed as a backup source. Charging and discharging rate of battery is importance to ensure the life time of the battery. At the end of this project a battery charger for hybrid source is successful design. By using this charger controller the efficiency of the system will be increase about 40 % compare to if only use solar battery charge.
