Abstract: This paper presents the performance of Solar Photo Voltaic (SPV) based grid connected multilevel inverter scheme having linear and nonlinear load connected at the Point of Common Coupling (PCC). Initially the analysis was carried out for the complete inverter circuit resulting in a slightly higher harmonics in PCC voltage and current, which can be further reduced to a lower value by connecting a filter. For a linear RL load, due to the filter, the THD in PCC voltage is reduced from 13% to below 5% (IEEE standard) and the THD in grid current decreases to below 5% from 14.8%. Similarly for a nonlinear load at PCC, a Diode Bridge, the harmonics in PCC voltage and the grid current can be further reduced to the lower level by connecting filter. The results obtained from simulation using SIMULINK/MATLAB Software are tabulated for SPV based grid tied system and also explained graphically.
