PROBLEM TO BE SOLVED: To provide a control device for a storage battery power conversion device capable of effectively forbidding the reverse flow of power charged in a storage battery.SOLUTION: When as an analog signal, a current detection signal is received which is inserted in the middle of a power line to a commercial system from a connection point where a power conversion device for a solar cell and the commercial system are connected to each other and which is from a current sensor of a CT sensor, and based on the current detection signal, it is determined that the inverse current flow occurs, a control device is characterized in that a switching part provided in a storage battery power conversion device switches connection/disconnection between a storage battery and the commercial system. |
