Arduino Based MPPT Solar Charge Controller

Abstract

Solar System is now widely used for green energy generation. However there arises a problem in voltage levels which affects the system stability. As the solar cell generates fewer amounts of charges we have to use a controller to maximize the efficiency. In this project MPPT method is developed with LM324 comparator with Optocoupler. The results are taken from wireless technique of Bluetooth module and a display panel interfacing with Arduino UNO. This system protects the battery from over charging and deep discharging to increase battery life.
