A method for controlling an inverter includes: when it is detected that a voltage across a BUS capacitor (C), that is, a BUS voltage is excessively large, controlling a photo-voltaic PV battery (500) to short-circuit, so that the BUS voltage drops; when the BUS voltage drops to a particular value, continuing charging, by the PV battery (500), the BUS capacitor (C), to control the BUS voltage to rise, so that the BUS voltage is kept within an operating voltage range of the inverter, and the inverter can be equipped with a PV battery having a higher open circuit voltage. Therefore, a charging rate of the BUS capacitor can be increased and a startup speed of the inverter can be increased. |
