Abstract:
A first connector for electrically connecting a first unit power terminal through a third unit power terminal to a power converter for performing conversion between a DC power and an AC power is mounted to a mounting port. In a status in which the first connector is being removed from the mounting port, it is impossible to mount the first connector to the mounting port while the first unit power terminal through the third unit power terminal are inputting and outputting a DC power, and it is possible to mount the first connector to the mounting port while the first unit power terminal through the third unit power terminal are not inputting and outputting a DC power.
Abstract:
An autonomous distribution board receives feeding of power via a distribution board for a period during which grid power is supplied from a grid power source, while receiving power via an autonomous terminal of a power conversion apparatus for a period during which supplying of grid power from grid power source is stopped. Autonomous distribution board is connected with a specific load and the like. A measurement point switching apparatus is configured to select one from a current sensor configured to monitor a current that flows through a main breaker, and a current sensor configured to monitor a current that is supplied from power conversion apparatus to autonomous distribution board. A fuel battery is configured to adjust an output thereof based on an output of the selected one so that power by fuel battery is consumed by a general load, specific load and the like.
