Claim 14:
15. The method according to claim 14, wherein the plurality of MPPT periods comprise a first MPPT period and N second MPPT periods before the first MPPT period, wherein N is a natural number greater than 1; and
obtaining the status of tracking the global MPP of the photovoltaic array in the target time period comprises:
starting the global MPPT of the photovoltaic array when a first multi-peak search start moment in the first MPPT period arrives, and determining to obtain a multi-peak search time period for a shade based on the first multi-peak search start moment when tracking a first global MPP of the photovoltaic array in the first MPPT period; and
obtaining a status of tracking the global MPP of the photovoltaic array in the multi-peak search time period in each second MPPT period.
