Abstract: A photovoltaic system and an I-V diagnosis method for a photovoltaic management apparatus. The photovoltaic system includes a power converter and a photovoltaic management apparatus. When an input end of the power converter is configured to connect to a plurality of photovoltaic units, the photovoltaic management apparatus delivers, in a preset time period in one day, an I-V scanning instruction to the power converter in response to that output current average values of the plurality of photovoltaic units at a current moment are in an I-V scanning current interval. When an input end of the power converter is configured to connect to one photovoltaic unit, the photovoltaic management apparatus delivers, in a preset time period, an I-V scanning instruction to the power converter in response to that an output current of the photovoltaic unit at a current moment is in an I-V scanning current interval.
