To improve performance of voltage profile and current profile of power quality issues in renewable sources. This paper propose a multi-functional grid connected inverter and MFGCI is improve both voltage-based and current-based power quality issues. Using a shunt-series MFGCI (SSS-MFGCI). The SSS-MFGCI is connected in series or parallel to grid which gives the compensation of the grid voltage. The propose system is implemented and validated the Simulation result. The proposed system more effective for multi-function grid connected.
