Claim 18:
19. The method according to claim 18, wherein obtaining the multi-peak search start moment of the global MPPT of the photovoltaic array based on the moment at which the global MPPT of the photovoltaic array is tracked comprises:
obtaining the multi-peak search start moment of the global MPPT of the photovoltaic array based on a moment, in the next MPPT period of the first MPPT period, at which the global MPPT of the photovoltaic array is tracked, and
when starting the global MPPT of the photovoltaic array at the initial multi-peak search start moment in the next MPPT period of the first MPPT period and tracking no global MPPT of the photovoltaic array, updating the initial multi-peak search start moment based on a preset start delay duration Tb until the global MPPT of the photovoltaic array is started at an updated initial multi- peak search start moment and the global MPP of the photovoltaic array is tracked, wherein Tb is less than Ts.
