Claim 0:
1. A photovoltaic system, comprising:
an inverter;
at least two converters, an input terminal of each of the at least two converters connected to a corresponding photovoltaic module, and output terminals of the at least two converters connected in series and connected to an input terminal of the inverter; and
a controller configured to set a voltage limiting value of at least one converter of the at least two converters, so that an output voltage of the at least one converter is less than or equal to a voltage limiting value when the converter works in a voltage limiting mode; and the set voltage limiting value of the at least one converter is proportional to an open circuit voltage of the photovoltaic module connected to the input terminal of the converter.
