Inverter, as one of photovoltaic (PV) system’s component coordinates various operating states such as supplying power to the grid, purchasing electricity from the grid and self-supply with solar power. Since we notice that PV power supply is a one-way process, where current only flows from PV generator in one direction directly into the grid and gradually coming to an end. In its place, self-supply with solar power is gaining important. In medium voltage range, particularly inverters are also increasingly undertaking tasks to stabilize the grid during voltage fluctuations.This paper reviews the inverter performance in a PV system that is integrated with a power distribution network (i.e., medium to low voltage), or we called it grid-connected PV system. Since the PV system is connected to the public grid, then the inverter eventually called “grid-tie inverter” (GTI). In general, the inverter used is a centralized inverter with settings based on the multiple power point tracker (MPPT) algorithm. The MPPT control is installed on both DC and AC sides which requires a voltage setting that is in accordance with the PV system.
