POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a convenient power supply system.SOLUTION: A power supply system comprises: a solar photovoltaic power generation section 10 that receives sunlight so as to generate power; a first power distribution board 50 and a second power distribution board 90 that are each connected to a commercial power supply 200 and the solar photovoltaic power generation section 10 and that distribute power among first loads 80 and second loads 120, respectively; a stationary power storage device 60 that is connected to the first power distribution board 50 so as to exchange power with the first power distribution board 50; an on-vehicle power storage device 30 that is connectable to the first power distribution board 50; and a fuel cell 100 that is connected to the second power distribution board 90 so as to supply power to the second power distribution board 90. When the on-vehicle power storage device 30 is connected to the first power distribution board 50 so as to supply power to the first power distribution board 50, the first power distribution board 50 is disconnected from the commercial power supply 200 and the solar photovoltaic power generation section 10.
