The present disclosure relates to photovoltaic power generation control, and specifically discloses a power distribution priority controller and a controlling method of a photovoltaic power generation system. The controller comprises: a calculating unit configured to calculate an electric device priority list according to running state information of electric devices and photovoltaic power generation data and to determine a preferred power distribution schemes; a controlling unit configured to acquire in real time the running state information of all electric devices, and control the electric devices according to the preferred power distribution schemes determined by the calculating unit; a communicating unit configured to transmit the photovoltaic power generation data, the running state information of electric devices, and control command information; a storage unit configured to store, in time units, the photovoltaic power generation data, the running state information of electric devices, and the preferred power distribution schemes. The present disclosure implements priority control and management of electric devices in the photovoltaic power generation system, which, in the case of that the photovoltaic power is insufficient, meets electricity demands of necessary electric devices according to a user's actual needs, so as to provide a more user-friendly option, thereby enhancing user experience and improving product competitiveness.
