The effective utilization of power from renewable energy is more crucial than power generation. This paper proposes standalone solar power system for a rural area with uninterrupted power. The uninterrupted power is essential for many applications. In this proposed system Solar power system with Battery Energy Storage System and Diesel Generator are contributed in power system for uninterrupted power. Effective utilization of solar power decides the efficiency of the power system. Effective Battery Management controller monitors and controls charging and discharging of BESS without any wastage of solar power so that the chance of using DG gets reduced. Conventional PI controller can control the charging. This paper proposes Fuzzy logic controller for required percentage of charging which is more efficient than PI controller. Comparison of charging controller based on PI and fuzzy logic controller are analyzed in this paper. The added main feature in the proposed system is the supplement Battery Energy Storage System which may replace BESS when there is any failure in BESS, it is monitored and controlled by EBMC. The entire system is simulated using MATLAB/Simulink.
