PURPOSE:To provide a system linkage type inverter which facilitates smooth and efficient operation management and failure diagnosis. CONSTITUTION:A system control circuit 14 detects an DC input flowing into an input terminal 2A and an AC output from an inverter circuit 5 to perform an operation control. Informations received from a system management center 18 which is connected with a telephone line are transmitted to the system control circuit 14. Further, a bidirectional communication circuit 17 which can control the driving control operation of the inverter circuit 5 which is performed by the system control circuit 14 and, moreover, receives the signals expressing the characteristic values of the DC input and the AC output which are detected by the system control circuit 14 and the signals expressing the operation status of the inverter circuits 5 from the system control circuit 14 and transmits the signals to the system management center 18 is provided. With this constitution, the operation status of the inverter circuit 5 can be detected and controlled by the external system management center 18. |
