摘要： A distributed power supply system is configured to execute a process for determining whether or not to permit a diagnostic process in such a manner that it is determined whether or not a difference between a set upper limit value and an actual measurement current value is not less than a load current value, the set upper limit value being a predetermined upper limit value set with respect to a detected current of a current sensor, the measurement current value being detected by the current sensor in a state where the diagnostic process is not executed, and the load current value being a value of a current flowing from a commercial power utility to a power load during execution of the diagnostic process; and if it is determined that the difference is not less than the load current value, the controller permits the diagnostic process.
