Abstract
Provided are a photovoltaic system and a method for controlling a photovoltaic system. The photovoltaic system includes a photovoltaic output device, an inverter device, an AC interface device, a control device and an AC load, where a supply terminal of the AC load is connected to an AC output side of the inverter device, and a control terminal of the AC load is connected to the control device, and the method for controlling the photovoltaic system is applied to the control device. The method for controlling the photovoltaic system includes: controlling the AC interface device to maintain the inverter device being disconnected from an electrical grid; starting the inverter device and then starting the AC load; and controlling the AC interface device to connect the inverter device to the electrical grid, in a case that it is determined that a grid connection condition is met for the photovoltaic system.
