Abstract:
A photovoltaic inverter system and an operation method thereof are provided. The photovoltaic inverter system includes photovoltaic modules, DC/DC converters, at least one direct current combiner device and a centralized inverter. An input signal or an output signal of each of the DC/DC converters is sampled by the DC/DC converter, and a loop process is performed by the DC/DC converter on the input signal or the output signal to maintain the input signal or the output signal at a preset value, so as to keep the output power of the photovoltaic module to be the maximum output power, thereby solving the problem of the series-parallel mismatch of a photovoltaic array due to being shaded or aging of a photovoltaic module. In addition, the photovoltaic inverter system can include only one centralized inverter. Therefore, the cost is reduced compared with photovoltaic inverter systems in the conventional technology.

Claim (Index 5):
The photovoltaic inverter system according to  claim 1 , further comprising:\n a protection element connected in series between a pair of the DC/DC converter strings, wherein the protection element comprises one or more of a diode, a metal oxide semiconductor (MOS) transistor, a controlled mechanical switch and a fuse.
