Abstract: A wireless network connection method includes: scanning a graphical code to acquire graphical code information carried in the graphical code, the graphical code information including encryption information and the encryption information being used for acquiring configuration information of a wireless network; decrypting the encryption information to acquire the configuration information; and connecting to the wireless network by using the configuration information.

Abstract: In one embodiment, a photovoltaic system includes a photovoltaic array, an energy storage converter, a storage battery, and a photovoltaic inverter. The energy storage is configured to: when electrical energy of a direct current generated by the photovoltaic array is greater than electrical energy required by a power grid in a unit time, supply one portion of the input direct current to the photovoltaic inverter, and store the other portion of the direct current into the storage battery; or when electrical energy of a direct current generated by the photovoltaic array is less than electrical energy required by a power grid in a unit time, supply the input direct current to the photovoltaic inverter as one portion of a direct current, and obtain the other portion of the direct current from the storage battery and supply the other portion of the direct current to the photovoltaic inverter.
