Abstract: The impact of solar power is one of the thriving concerns in the world today. The proper utilization of solar energy in modern life style opens a wide path to new technologies. This paper deals with simulation and analysis, design, of an isolated gridconnected inverter for photovoltaic (PV) applications. The system uses an interleaved flyback converter followed by a single phase inverter. Flyback topology works in discontinuous current (DCM) mode of operation .The aim of this paper is to monitor PV module effectively and operate flyback converter at high power with good performance which is difficult to implement. The interleaved inverter system rated at 1kw gives an added benefit of reduced size of passive filtering element and reduces the overall cost. A simulation model of the proposed inverter system is developed and the design is verified for good performance based on the simulation results. Maximum power tracking of the solar energy is facilitated through maximum power point tracking (MPPT) for each PV panel with reduced maintenance cost and time.
