A maximum power point tracking device and an operation method thereof are provided. The maximum power point tracking device includes a DC-to-DC converting circuit, a DC-to-AC inverting circuit, a controlling circuit, an auxiliary power supply and a power limiting circuit. The auxiliary power supply is connected to the DC-to-DC converting circuit, the DC-to-AC inverting circuit and the controlling circuit to provide power. The power limiting circuit is connected to a photovoltaic array and the auxiliary power supply. The power limiting circuit includes a dummy load path and an auxiliary power providing path. The dummy load path is used to provide a dummy load, when a photovoltaic power of the photovoltaic array is lower than a predetermined power. The auxiliary power providing path is used for providing the auxiliary power when the photovoltaic power of the photovoltaic array is higher than or equal to the predetermined power.
