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 10):
The photovoltaic inverter system according to  claim 1 , further comprising:\n a photovoltaic string connected to the input end of the direct current combiner device, wherein\n the photovoltaic string comprises one or more of the photovoltaic modules connected in series with each other; or \n the photovoltaic string comprises one or more of the photovoltaic modules and one or more of the DC/DC converters connected in series with each other.
