Claim 5:
6. The photovoltaic system according to claim 5, wherein the MPPT controller is further configured to: 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, update 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.
