The power generation from renewable energy resources is popular due to increase in energy demands, depletion of fossil fuels and enforcement of carbon emission reduction. Nowadays, solar photovoltaic Energy generation is increased due to reliability and availability of solar for many hours. Due to development in power electronics converter, high efficient power transfer is possible. In this research, transformer-less solar PV system was design for both grid connected operations and Island mode of operations. The modulated output of the VSI results in generating switched voltages, which produces distorted currents. Passive damping technique is used designing of LCL Filters to reduce the distortion in output voltage and current. Performance of Transformerless solar PV inverter was evaluated in two modes of operation include grid tied operations and Island mode of operation and stability of controllers was analyzed using pole zero plot and Bode plot.
