As convention fossil fuel energy sources diminish and the world’s environmental concern about acid deposition and global warming increases, renewable energy sources (solar, wind, etc) are attracting more attention as alternative energy sources. ¾These are all pollution free and one can say eco friendly. ¾These are available at free of cost. In India, there is severe power shortage and associated power quality problems. ¾ The quality of the grid supply in some places is characterized by large voltage and frequency fluctuations, scheduled and UN scheduled power cuts and load restrictions. ¾ Load shedding in many cities in India due to power shortage and faults is a major problem for which there is no immediate remedy in the near future since the gap between the power demand and supply is increasing every year. The main aim of the project is to design a hybrid power generation for DC appliances using renewable energy such as solar, wind and also other source is grid. These three energies are obtained is stored in to a battery with the help of charging circuit. The battery voltage will give to the DC-DC Boost converter and it boosts up the voltage. These battery voltage is using to switches on the loads. Here we are using DC motor as a vehicle, LEDs as loads. In this project devices are controlled by blink app through IOT and also battery voltage is fed as input the Nodemcu to monitor battery voltage into the blink app. Node MCU is main controlling device of the project which is interfaced two devices through relay. Here relay works as a switch to on/off the DC devices.
