The present invention relates to a solar uninterruptible power supply management system. The solar uninterruptible power supply management system includes a main controller, solar photovoltaic cells, an overcurrent and overvoltage protection circuit, anti-backflow control circuits, an input undervoltage judging circuit, a maximum power point tracking and battery charging and discharging management unit, a lithium battery pack, a battery voltage acquisition and balanced charging circuit and a multiple-output control circuit. According to the solar uninterruptible power supply management system of the invention, a direct current-to-alternating current conversion step is directly bypassed, an input power source is subjected to voltage reduction through a maximum power point tracking maximum, and the voltage-reduced input power source is used for charging the batteries, and at the same time, an inner power source voltage reduction chip is adopted to output a stable power source to an external device; the lithium batteries are used for storing energy; and the solar uninterruptible power supply management system is provided with the battery protection circuit, an integrated data memory, the input anti-backflow circuits and a plurality of communication interfaces, can effectively utilize the electric energy of the solar photovoltaic cells, has a fault early warning function, can provide the working state of the whole system in real time and can support multi-power source controllable output and multi-power source input.
