The project aims at developing a system which makes use of wind, Battery and solar energy for rural electrification. Wind and solar energy are treated as nonrenewable source of energy. The system also uses inverter to switch the AC devices. The purpose of this project is to monitor the power of solar, wind and battery through voltage sensor will be display on LCD. whenever battery get full charged it will stop the battery charging automatically through Relay. The wind and solar energies are obtained stored into a battery. The battery supply is fed as input to the inverter which converts DC to AC. This AC voltage is fed as input to the step-up transformer which converts 12v AC to 230Vac which uses to switch ON/OFF the electrical appliances like bulb. Micro controller will measure the voltage values of Solar, wind and battery through sensors and will be display on LCD module. When the battery voltage is sufficient it will turn OFF the charging automatically through relay. To achieve this task microcontroller loaded program written in embedded C language.

  Features of this project:

• Using renewable energies solar, wind.
