POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a power supply system capable of solving problems of a space assuring the installation of a power collection panel, cost increase and the complicatedness of wiring by enabling power feeding to the outside and state monitoring from the outside without needing the power collection panel. SOLUTION: Multi-conductor cables 32 are successively connected between respective small system link inverters 3 in respective AC modules 1. The cables 32 include a 1st power cable for power feeding and a 1st alarm cable for state monitoring. A small system link inverter 3 located at the end of cross connection by the respective multi-conductor cables 33 is connected to an alternating current load 15 and a commercial alternating power supply 16 through an output power cable 33 and is also connected to a monitor device 18 through a 2nd alarm cable 34.
