摘要： It is checked whether or not a primary-side voltage (V1) of a remote shutoff breaker (32) and a secondary-side voltage (V2) thereof become a rated voltage after a commercial power system is recovered from a blackout. Next, when both primary-side voltage (VI) and secondary-side voltage (V2) become the rated voltage, a contactor (33) is actuated to interconnect a home power system with the commercial power system. Hence, charging of the home power system without causing a user to notice such a charging upon recovery of the commercial power system from a blackout can be prevented. As a result, the safety for the user can be ensured.
