Centralized Architecture
The centralized architecture is best thought of as all the rectifier outputs of the individual cabinets and
the battery strings of the plant, connected together on a single dc bus, with the loads connected,
through the centralized distribution modules, to the same dc bus. Since all the system power is
brought together at a central point, the central point must be sized for the ultimate capacity of the
system. Growth of the system is accomplished by increasing rectifier capacity (adding ac inputs and
shelves to an existing cabinet or adding another cabinet to the plant), adding more distribution panels
(to an existing cabinet or adding a new cabinet), or by adding more batteries.
