Abstract
This application discloses an inverter of a grid-connected photovoltaic power generation system. The inverter includes a grid-connected inverter unit, an alternating current auxiliary power supply, and a startup apparatus. The alternating current auxiliary power supply is configured to convert an alternating current from an alternating current power grid into a direct current. An input terminal of the grid-connected inverter unit is connected to a bus capacitor. The startup apparatus is configured to: obtain an alternating current from the alternating current power grid, convert the alternating current into a direct current, and then provide the direct current to the bus capacitor, to start the grid-connected inverter unit. By using the inverter, the grid-connected photovoltaic power generation system can be started normally when there is insufficient or no sunlight, to allow scheduling of the grid-connected photovoltaic power generation system to be normally performed.
