  "textContent": "This application discloses a photovoltaic system and a carrier wave signal synchronization method. The photovoltaic system includes a plurality of inverters and a controller. Each inverter in the photovoltaic system inverts a direct current into an alternating current based on a received carrier wave signal, and transmits the alternating current to a power grid. The controller obtains first output currents of the plurality of inverters in an adjustment period, so that the controller can obtain first output current valid values of the plurality of inverters based on the first output currents of the plurality of inverters. A phase of a carrier wave signal of a first target inverter is adjusted, so that carrier wave signal synchronization can be performed on the plurality of inverters in the photovoltaic system without changing the existing photovoltaic system, to implement closed-loop suppression for a circulation current. Finally, closed-loop suppression for a circulation current in the entire photovoltaic system is implemented, a loss of an inverter is reduced, and reliability of the photovoltaic system is improved.",
