A method for controlling a photovoltaic energy storage device includes: obtaining a load required power when a photovoltaic panel does not output electric energy; generating a first driving signal according to the load required power; obtaining an output voltage of a direct current conversion circuit; outputting a second driving signal to the direct current conversion circuit if the output voltage of the direct current conversion circuit is greater than a preset open-circuit voltage, until the output voltage of the direct current conversion circuit is not greater than the open-circuit voltage. When it is detected that the output voltage of the direct current conversion circuit is greater than the open-circuit voltage, a duty cycle of a switching tube of the direct current conversion circuit is controlled to be reduced, so that the output voltage of the direct current conversion circuit is not greater than the open-circuit voltage, thereby avoiding an overload of the direct current conversion circuit.
