This project proposes a topology for Fuzzy PI controller based single-phase Hybrid solar photovoltaic (PV) inverter with for Domestic applications. The proposed Hybrid power converter consists of a PV cells, MPPT algorithm, switched mode buck boost converter in the DC side, battery bank and a single phase bridge inverter. The Control strategy of the inverter gate pulses are done by the sampling of sinusoidal pulse width modulation (SPWM) with a square wave which is controlled by Fuzzy and PI combined controller, along with grid synchronization condition. The performance of the proposed inverter is simulated under grid-connected scenario and load disturbances. The output of PV module system is enhanced by the maximum power point tracking (MPPT) technique using P & O algorithm in order to increase the systems efficiency. This system is more useful for the households as it has both power storing and saving applications.
