In this paper introduced the grid integrated PV Simulink module using converter instead of transformer to transform the DC voltage into a high-quality AC voltage. This sort of system module referred as transformer less PV Simulink system module. The proposed Simulink system module based on filtration mechanism to mitigate the harmonics presented in the system module during the transmission of power towards grid. In this paper, proposed two mechanism of filtration, first one is module using LCL resonant filter and second one is digital filter. The presented Simulink module has been consisted several module blocks like MPPT, CSI, VDC, current and voltage regulator, controller for inverter. In this module system, MPPT getting the voltage from PV panel module for boosting it and transferred to CSI and then output of this further driven by SPWM which further filtered by the digital filter and LCL filter and then computed the total harmonics distortion which is 0.19% for digital filter-based PV inverter Simulink module system and much better than the LCL filter.
