Most of the energy sources originate from tried and conventional sources like fossil fuels, for example, coal, natural gasses and crude oil. Then comes the hydro power systems. These powers are frequently termed as non-renewable energy sources. But generation of hydro power requires water storage systems. As the conventional energy sources are present in limited amount generation of renewable energy sources like solar, tidal etc. is a great necessity of these days. In this project we have modelled the standalone voltage source inverter first by using a DC source as input power and then instead of using direct DC source, a PV system is connected as input source and the output of the inverter is studied and analyzed. The unregulated DC output supply of the PV array is mainly because of changes in weather conditions. The maximum power is tracked with respect to irradiance levels and temperature by the help of DC-DC converter. The AC output voltage and frequency are regulated. Sinusoid pulse width modulation (SPWM) technique is implemented for voltage control for inverter and it is a closed loop control. For the design of inverter, its state space model is formulated and effects of various parameters like load resistance, controller gain and time constant is analyzed
