Smart Solar Charge Controller for Traffic and Street Light Applications

Abstract

As a sustainable and alternative source of renewable energy, utilization of solar power has become immensely popular nowadays. Much better utilization of natural resources has become great concern to reduce cost and for efficiency improvement. Frequent overcharging and over discharging leads to an early battery failure. The current flow in the electric batteries can be limited by a charge controller. Solar charge controller plays crucial role and ensures reliability, better performance and durability of the installed systems. This paper discuss the performance of a microcontroller based charge controller coupled with an solar Photovoltaic (PV) system for improving the charging and discharging control of battery. The lifespan of the battery can be improved by solar charge controller by preventing the overcharging and over discharging. The good performance of the charge controller and the power quality improvement is demonstrated in the results. Proteus is the simulation tool used to establish the results.
