Abstract: An Uninterruptible Power Supply (UPS) system includes a processor, an input coupled to an AC power source to receive input AC power, a converter circuit coupled to the input and configured to convert an input AC voltage to a DC voltage, an energy-storage component, a load output configured to provide output power derived from the DC voltage, and a radio-frequency circuit configured to receive a radio-frequency signal. The radio-frequency circuit includes an antenna and a memory. The memory stores instructions that, when executed by the processor, cause the processor to receive configuration data including a first UPS identifier from a component of the radio-frequency circuit. The instructions further cause the processor to compare the first UPS identifier to a second UPS identifier stored on a memory of the UPS system. The instructions further cause the processor to configure operation of the UPS system based on the configuration data.
