A solar UPS system, comprising a utility power input, an alternating-current output, a generator power source, a solar battery assembly, a storage battery pack, a main controller, a gating controller, an inverter, a first rectifier, a static switch and a plurality of gating switches. The utility power input is divided into a bypass input and a rectification input. An output end of the first rectifier is connected to the storage battery pack; a direct-current output end of the generator power source is connected to a direct-current input end of the inverter; an alternating-current output end of the inverter is connected to an input end of the static switch; and an output end of the static switch is connected to the alternating-current output. One end of each gating switch is connected to a power source output end of each solar battery panel in the solar battery assembly in one-to-one correspondence, and the other end thereof is respectively connected to the storage battery pack. Each gating switch is controlled by each gating control end respectively. By means of the system, the power of each path of power source input can be automatically selected and allocated according to load requirements, thereby realizing the optimal power source output. |
