PROBLEM TO BE SOLVED: To provide a power supply system which can utilize effectively whole power generated by a fuel battery and further can be charged efficiently with power generated at a power generating portion, without inhibiting learning function of the fuel battery.SOLUTION: A power storage device 40 is directly charged (DC charging) with power directly supplied from a photovoltaic power generation section 30 to the power storage device 40. When arrangement of the power storage device 40 is switched to a further downstream side than a distribution board 10, power discharged from the power storage device 40 can be supplied to the distribution board 10 from the downstream side, and excess power supplied from a fuel battery 80 to the distribution board 10 can be supplied to the power storage device 40. When the arrangement of the power storage device 40 is switched to a further upstream side than the distribution board 10, the power discharged from the power storage device 40 can be supplied to the distribution board 10 from the upstream side and the fuel battery 80 can perform a learning function on the basis of the supplied power. |
