Methods and systems are disclosed for automatically tracking and controlling the capacity ratings of UPS units. The methods and systems provide a central server or repository for storing the capacity ratings, grant kVA and grant code authorized for each UPS unit along with a unique security key for each unit. When a customer purchases a capacity upgrade, the server updates the capacity rating for the customer's unit and issues an upgrade grant that includes the new rating and the grant code. The upgrade grant may thereafter be downloaded by a service technician and used to upgrade the unit. Alternatively, the upgrade grant may be downloaded directly to the UPS unit, and the unit's software and/or firmware may perform the upgrade automatically. In either case, the upgrade may be performed through a software modification, thus eliminating the need for the technician to physically swap out hardware. Such an arrangement helps ensure that only authorized capacity upgrades are performed.

Adaptive capacity power supply

The present disclosure provides a method and system using a power protector, such as an uninterruptible power supply (power protector) or a power line conditioner. An input of the power protector can be coupled to an output of one or more of circuit breakers using electrical buss bars for unique modularity and easy installation and replacement. Further, an input of a second set of circuit breakers can be coupled to an output of the power protector to backfeed the power through the second set of circuit breakers and out through the buss bar to one or more electrical loads. Additional power protectors can be used for capacity and/or redundancy. A stacked buss bar system can be used that consolidates the system into a compact assembly heretofore unknown in the industry. In at least some embodiments, the system can be compatible with standard panelboards having circuit breakers disposed therein.
