  "textContent": "This application provides a method and apparatus for obtaining location information of a controller. The method includes: An inverter obtains signal feature information of each photovoltaic unit in a high-voltage direct current string, where the signal feature information of a photovoltaic unit includes a communication identifier of the photovoltaic unit and a signal feature of another photovoltaic unit, and the photovoltaic unit includes one controller and at least one photovoltaic module; the inverter determines an installation sequence of all photovoltaic units based on signal feature information of all the photovoltaic units; and the inverter determines relative installation location information of each photovoltaic unit based on relative installation location information of a target photovoltaic unit in the high-voltage direct current string and the installation sequence of all the photovoltaic units, where the target photovoltaic unit is at least one photovoltaic unit in the high-voltage direct current string. Therefore, location information of the controller in the high-voltage direct current string in a photovoltaic system can be obtained, and labor is saved.",
