Abstract: A complete renewable energy system uses one charge controller with by grouping all batteries connected into parallel strings. Uncertainty of renewable energy systems, notably the physical phenomenon (PV) and electric cell systems, and constraint of battery power charging and discharging area unit fundamental issues for developing with and managing battery storage systems of complete renewable energy systems. Within the previous analysis localized management mechanism is planned and is a sensible limitation even though we tend to implement a tiny scale model. So in this paper proposes an alternative optimization method called constant current control method to provide system stable performance to optimize the reliability of system to the maximum extent total circuitry is modeled and simulation under graphical user interfacing environment and MATLAB based simulation results are provided. The total proposed circuit configuration will provide optimal performance than a typical decentralized technique.
