  "textContent": "A photovoltaic inverter and a method for controlling the photovoltaic inverter are provided. The photovoltaic inverter includes a main circuit and a controller. A direct-current side of the main circuit is configured to connect a photovoltaic array, and an alternating-current side of the main circuit is configured to connect a power grid and/or a load. The controller controls the main circuit to operate; and in response to an occurrence of a power oscillation in the main circuit, regulates a direct-current voltage of the main circuit to an open-circuit voltage or a voltage close to the open-circuit voltage and then controls the main circuit to perform a global MPPT search based on the regulated voltage.",
