**Abstract:**

The photovoltaic (PV) system is efficacious and thus has universal employment like the usage of LED-based street lights, electronic chokes, and compact fluorescent lampsin this machinery world. The system under study is a grid connected PV system supported by a battery, supplying DC loads which is directly connected to the DC bus. As multiple sources (PV, battery, grid) and sinks (battery, grid, DC loads) are included, a viable Power flow Management Strategy (PMS) is required to balance power flow. The PMS manages the multimode operation of bidirectional converter, battery charging and discharging cycle which enables a grid-friendly operation. MATLAB/SIMULINK software was used to simulate the proposed system. Finally, the objectives are validated through the simulation results to prove the effectiveness of the system.
