1. A method for monitoring energy, comprising: providing a plurality of single phase energy monitoring devices, each of such single phase energy monitoring devices comprising a first data combiner, a single phase metrology board for generating single phase energy related data, and a second data combiner; connecting the plurality of single phase energy monitoring devices in a seriatim configuration; combining a signal from a first data combiner in a first of the plurality of single phase energy monitoring devices in the seriatim configuration with energy related data from the single phase metrology board of a second of the plurality of single phase energy monitoring devices in the seriatim configuration; and determining total multiphase monitored energy by monitoring an output from the second data combiner in a second of the plurality of single phase energy monitoring devices in the seriatim configuration.
