  "textContent": "This application discloses a photovoltaic system and a control method. The photovoltaic system includes an inverter, a controller, and at least two converters. An input terminal of each of the at least two converters are connected to a corresponding photovoltaic module, and output terminals of the at least two converters are connected in series and connected to an input terminal of the inverter. The controller is configured to set a voltage limiting value of at least one of the at least two converters, so that an output voltage of the at least one converter is less than or equal to the voltage limiting value when the converter works in a voltage limiting mode. The voltage limiting value of the at least one converter is proportional to an open circuit voltage of the photovoltaic module connected to an input terminal of the converter. Open circuit voltages of different photovoltaic modules vary with different parameters or models of the photovoltaic modules. Consequently, voltage limiting values of converters connected to the photovoltaic modules are different. In this way, for the voltage limiting value configured for each converter, the open circuit voltage of the photovoltaic module connected to the converter is fully considered, so that the converter works at high conversion efficiency.",
