| description | Disclosed in the present application are a photovoltaic system and a control method. The photovoltaic system comprises a controller and an inverter. An input end of the inverter is used for connecting to a plurality of photovoltaic strings, the plurality of photovoltaic strings being connected in parallel, and each photovoltaic string comprising photovoltaic panels and optimizers. The controller is used for controlling an input voltage of the inverter to be smaller than or equal to an MPPT voltage of a first photovoltaic string, the first photovoltaic string being the photovoltaic string having a minimum open-circuit voltage amongst the plurality of photovoltaic strings. The inverter is used for carrying out MPPT scanning on the plurality of photovoltaic strings. The optimizers are used for obtaining photovoltaic panel MPPT voltages corresponding to the photovoltaic panels, and used for keeping the photovoltaic panels all working at the corresponding photovoltaic panel MPPT voltages. The present application c |
