Abstract: An access point (AP) energy saving method and an AP relate to the field of communications technologies, and effectively implement energy saving for the AP. The method includes determining that an AP is not associated with any terminal and there is not any to-be-associated terminal within a preset time segment, and turning off, by the AP, an extended radio frequency circuit, where an operating frequency band of the extended radio frequency circuit is a wireless local area network (WLAN) frequency band other than a 2.4 gigahertz (GHz) frequency band.

Abstract: An inverter in a power generation system converts a direct current that is input from a direct-current-side device into an alternating current for power supply. The inverter includes a control apparatus and a communications apparatus. The control apparatus controls the inverter to convert the direct current that is input from the direct-current-side device into an alternating current for power supply. The communications apparatus is coupled to the control apparatus, and sends a networking information request signal used to request networking information to the direct-current-side device in the power generation system through a direct-current power line, where a frequency of the networking information request signal is within a first frequency band. The communications apparatus also receives the networking information from the direct-current-side device; and sends a control signal to the direct-current-side device, where a frequency of the control signal is within a second frequency band.
