This paper presents a grid tie inverter (GTI) in photovoltaic, PV system for residential application. The proposed GTI will be switched with a combination switching strategy of square wave and the sinusoidal pulse width modulation, SPWM. The combination switching strategy will be discussed and the performance of the inverter also will be simulated under grid tie condition in SIMULINK. Moreover, the strategy of sending power into the grid also will be discussed
