Abstract:
1. A solar power management system for managing an electric energy conversion by a photovoltaic cell, supplying a converted electric energy to an external load, and storing the converted electric energy in a battery; the solar power management system comprising: a maximum power tracking (MPT) circuit receiving the electric energy converted by the photovoltaic cell and regulating an output current of the photovoltaic cell to regulate an output power of the photovoltaic cell, and the MPT circuit comprising: a charging circuit converting the output electric energy from the MPT circuit into a predetermined charging current and a predetermined charging voltage for charging the battery; and a voltage conversion module converting the output electric energy from the MPT circuit into a setting voltage format for outputting to the external load; wherein the phase inverter circuit outputs a phase-inverted voltage to the voltage regulating circuit as the setting voltage.
