In this paper, we have proposed a new technique for Switched Capacitor based inverter based on a standalone photovoltaic module. The new technique is based on PI based controller. The purpose of this control system is to saturate any fluctuations of the output of the solar panel or the standalone PV module and give a clear DC constant input voltage to the main circuit of switched capacitor. The switched capacitor is used to give capacitance value according to the pulses given in the SC (switched capacitor) module gates of the transistors used for switching. The possibility of executing Maximum Power Point Tracking which is to realize it as a measurable augmentation in the efficiency of the Photovoltaic System. Initially, the Switched capacitor based driven with P and O MPPT technique gives about 4-6% of THD output sine wave. In the proposed algorithm, the P and O technique is modified with the use of Fuzzy Controller and PI controller which stabilizes the system, lowers cost and is easier to implement. The THD values are improved by 88%, THD is less than 1% and the efficiency is about 99%. Photovoltaic (PV)based proposed algorithm is a technique for producing electrical power in AC mode by changing solar radiation into coordinate current power utilizing semiconductors that display the photovoltaic impact.
