PHOTOVOLTAIC SYSTEM, AND METHOD FOR GROUPING PHOTOVOLTAIC UNITS

This application discloses a photovoltaic system, a photovoltaic unit grouping method, a computing device, and a storage medium, and relates to the field of photovoltaic technologies. The photovoltaic system includes an inverter and a plurality of photovoltaic units connected to the inverter. Each photovoltaic unit includes a controller and one or more photovoltaic modules connected to the controller. The controller in each photovoltaic unit is further configured to obtain a power carrier signal sent by a controller in another photovoltaic unit of the plurality of photovoltaic units, determine an attenuation reference factor of the power carrier signal based on the obtained power carrier signal, and send the attenuation reference factor to the inverter. The inverter is further configured to determine, based on the attenuation reference factor, an attenuation degree of the power carrier signal obtained by the controller in each photovoltaic unit, and group the plurality of photovoltaic units based on the attenuation degree of the power carrier signal obtained by each photovoltaic unit. This application can implement automatic grouping of photovoltaic units.
