The loading density of canisters fitted to a supporting substrate of a storage enclosure is reduced. A plurality of rail structure bodies are provided in parallel with the Y-axis direction so as to be spaced apart by a first predetermined distance in the X-axis direction. A pair of the rail structure bodies arranged on left and right sides in the Y-axis direction support the canisters. The rail structure body includes first contact parts extended in parallel with the Y-axis direction, second contact parts formed continuously with the first contact parts so as to protrude by a second predetermined distance to one side in the X-axis direction, and coupling parts formed continuously with the first contact parts and the second contact parts. The canister is supported between one side surface of the second contact part of one rail structure body and the other side surface of the contact part.

In a storage system provided with a plurality of storage modules, the rated power consumption can be reduced. The storage system is provided with a charge control unit. The charge control unit stops, when detecting that a predetermined number of a plurality of battery modules are during battery charging, the battery charging in the remaining battery modules.

An object of the invention is to render replacement of controllers for identifying failure information unnecessary. Failure monitor unitsandin power suppliesandare connected mutually via pathsand, the failure monitor unitsandin the power suppliesandare connected to failure monitor unitsandin controllersandvia pathsand, and LEDsandare connected to pathsand. The failure monitor unittransfers, when a failure occurs in the power supply, failure information to the failure monitor unitin the power supplyvia the path. The LEDis lit by both the failure monitor unitsand. The failure monitor unitsandtransfer failure information indicating failure occurrence in the power supplyto the failure monitor unitsandin controllersandvia a path. The failure monitor unitsandnotify a maintenance PC of the failure occurrence in the power supply
