Abstract: A first battery pack includes a first battery module and a first controller. A second battery pack includes a second battery module and a second controller. The first battery pack and the second battery pack are installed to be freely attachable and detachable in relation to a main body. An activation manager performs an activation instruction such that the first controller and the second controller do not activate at a same timing. The first controller which activates earlier operates in an ordinary mode in which power is supplied from the first battery module to an AC load. The second controller which activates later operates in a standby mode in which power is not supplied from the second battery module to the AC load.

Abstract: A third relay switches between an output of a first AC power source fed via a first relay and an output of a second AC power source fed via a second relay, and supplies the output after the switching to a load. A welding detection unit detects welding of the first relay. In order to switch the output of the first AC power source to the output of the second AC power source and supply the output of the second AC power source to the load, a power source switching control unit switches the first relay from the closed state to the open state, switches the third relay so as to select and feed the output of the second AC power source, and then prohibits switching of the second relay from the open state to the closed state until a first-relay welding detection processing by the welding detection unit is completed.
