This paper shows a control technique for multifunctional Photovoltaic inverter for the grid-tied system that employs conservative power theory with maximum power point tracking Perturb and Observe. Presented three-level multifunctional inverter enhance quality of supply power and assist the utility grid by supplying power to the various non-linear loads. During the daytime, the proposed system carries out multiple functionalities of enhancing the quality of power by working as STATCOM/active filter and also transfers power to the load and the grid acquired from the Photovoltaic array. In the nighttime, the presented system support grid as STATCOM enhances the power quality. The presented system is also capable to provide reactive support to the utility grid at Low voltage event and detects islanding. Loborateory results proofs efficacy of presented multilevel multifunctional Photovoltaic inverter for various and simultaneous tasks. To achieve high efficiency with low-cost inverter topology without dc-dc converter and transformer-less PV to grid interface is examined in this paper. This makes the proposed inverter very smart and interactive
