Abstract: The energy demand in the world is steadily increasing and new types of energy sources must be found in order to cover the future demands, since the conventional sources are about to be emptied. One type of renewable energy source is the photovoltaic (PV) cell, which converts sunlight to electrical current, without any form for mechanical or thermal interlink. A photovoltaic (PV) based 500W solar inverter system is developed which consists of PV Array, battery bank and solar inverter cum charge controller. The system works on both Solar and AC mains power depending on the energy requirement. The goal of this project is to Simulate, design, develope and analyzes the PV based inverter system. Simulation of solar cell is carried out in MATLAB/SimElectronics which can be used to analyze photovoltaic panel in varying atmospheric conditions. The inverter is MOSFET drive H Bridge PIC controlled single phase SPWM. The system is tested on resistive and inductive load. Voltage/current waveform analysis, power quality and FFT analysis is carried out by using power quality analyzer as well as load sharing between photovoltaic array and battery, battery and mains supply is done.
