SINGLE OPERATION DETECTION APPARATUS, POWER CONDITIONER, DISTRIBUTED POWER SUPPLY SYSTEM, PROGRAM, AND SINGLE OPERATION DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a single operation detection apparatus capable of solving a problem in that when a single operation detection apparatus is modularized as a unit separated from a controller that controls a power conditioner, the single operation detection apparatus is unable to confirm whether the controller is surely working as per instruction just giving the instruction to the controller.SOLUTION: A single operation detection apparatus includes: a request signal transmission section for transmitting a request signal to a control apparatus that controls a power conditioner, so that an electric current output from the power conditioner is varied according to the request; and a response signal reception section for receiving a response signal from the controller so that the electric current output from the power conditioner is subject to vary in response to the request signal.
