PROBLEM TO BE SOLVED: To provide an electric power supply unit capable of preventing abnormal voltage fluctuation on a power line while using an existing solar power conditioner.SOLUTION: The electric power supply system includes: a first path that includes an AC power path to which a system power is fed to supply the electric power to a specific load, a power storage unit and a first power conditioner which is disposed across the power storage unit and the AC power path therebetween; and a second path that includes one or plural power generation units, one or plural second power conditioner capable of operating with the power storage unit, a second power conditioner disposed across the power generation unit and the AC power path, and a control section that controls the connection between the second path and the AC power path therebetween. When the system power and the AC power path are disconnected from each other, the control section controls the second power conditioner to turn ON/OFF according to the power generation output from the power generation unit and the power consumption of the specific load. |
