I had been looking for a whole-house AC utility monitor to track my utility electricity consumption beyond what I produce with my PV system. I wanted to be able to graph my energy usage daily, weekly, and monthly. However, none of the available data logging systems I found were user-friendly or affordable.
That changed when I found the Efergy Elite wireless electricity monitor. After a year of use, I can say this product meets my requirements nicely. It is a plug-and-play device, connected to my service panel. Two sensors encircle each of the two hot leads from the utility meter, and plug into a battery-powered transmitter, which mounts on the wall next to the main breaker box. It transmits wirelessly to the monitor that can be moved around the house. It displays power consumed in real-time by all circuits, and circuits (or individual appliances) can be turned off one by one to get consumption detail. The monitor is capable of data logging power (and energy) use in various ways, including cost at present rates. This system can also be used by off-gridders, regardless of the power supply.
This monitor suits my needs nicely, and took less than 30 minutes to install and configure. Also, the price was reasonable, at approximately $150 Canadian. Please note that I do not sell these products, nor am I affiliated with the manufacturer or distributor in any way. Home Power has helped me so much for so many years, and now I like to spread the word on appropriate technology when I can.
