Design of charge controller for solar PV systems

Abstract

The purpose of this project is to develop a low-cost, efficient solar charge controller. The system utilizes the use of Solar PV system more effectively by increasing the battery life.With a battery rated at 9A, the charge controller adjusts its output to a step of 12V. The design consists of four phases, including a power supply unit, a battery charge controller, a current booster, and a battery level indicator. The system as conceived is exceedingly practical, cost-effective, and efficient. This work is a prototype for a commercial solar charge controller that includes safety features to guard against battery damage brought on by uncontrolled charging and draining mechanisms. This proposed system of low cost more effective solar charge controller has potential to improve the efficiency of batteries.
