During charging operation, the flow of energy is from dc bus to BSS. Similarly, it behaves as boost converter during discharging operation and the flow of energy is from BSS to dc bus. In this case, suitable controller is implemented for regulation of dc-bus voltage of the PV system.

The PV array is interfaced through a dc–dc boost converter and is controlled with the help of an MPPT controller to extract the maximum power. The battery backup unit is integrated with the PV system through a common dc bus for the power management within the system as well as to maintain a constant dc bus voltage.
