PROBLEM TO BE SOLVED: To provide a distributed power supply system, wherein a plurality of distributed power supply units can be operated in parallel without troublesome setting. SOLUTION: A distributed power supply system comprises distributed power supply units 7, which allow network separation between direct-current power supplies 8 and a commercial power supply 1 and a display 15, capable of indicating the condition of operation of the distributed power supply units 7. The display 15 is provided with a plurality of terminals 15f, to which the distributed power supply units 7 are connectable, a transmission and reception circuit 15a, which transmits confirmation signals to the connection terminals 15f and receives reply signals corresponding to the confirmation signals from the distributed power supply units 7, and an operation control circuit 15b which determines the condition of connection for the distributed power supply units 7, from the presence or absence of a reply signal received by the transmitting and receiving circuit 15a. |
