The multi-point monitor provides energy measurement at the service entrance to the home and features additional channels that are used track sub-panels, larger appliances or alternative energy power generation. Assignment of current transformers, or CT's, to specific loads is done within the software during the set-up process as well as how the data will be aggregated.
When evaluating a multi-point monitor pay close attention to the channel configuration as this will determine how many and which kinds of loads can be measured. Sizing an energy monitor to match the number of appliances or loads you wish to track is an important part of the selection process.
In the table below we designate channels as main or auxilliary. A main channel has two CT inputs and serves 240 volt split phase loads. Auxilliary channels have only one input and serve 120 volt loads. Some units allow auxilliary channels to be combined to measure 240 volt split phase or 277 volt 3-phase power.
