SOLAR POWER STORAGE MODULE, AND SOLAR POWER STORAGE SYSTEM AND SOLAR POWER SUPPLY SYSTEM HAVING SAME

摘要

A solar power supply system includes a power supply bus and a plurality of solar power storage systems. The power storage systems is electrically connected to each other in parallel via the power supply bus. Each of the solar power storage systems includes solar power storage modules and an inverter electrically connected to an external load and the solar power storage modules in series. Each of the solar power storage modules includes a lithium-ion battery unit, a solar cell unit, and a battery control unit. The solar cell unit charges the lithium-ion battery unit. The battery control unit is electrically connected to the lithium-ion battery unit and the solar cell unit, and controls the lithium-ion battery unit being charged or discharged.
