Hi All,
I am just setting up our first Enphase S280 system with the new Envoy S series Standard or basic model PV monitor. The advanced Envoy S boasts;
Envoy-S, Metered
Enphase® Envoy-S communications gateway with integrated revenue grade PV production
metering (ANSI C12.20 +/- 0.5%) and optional consumption monitoring (+/- 2.5%).
And there is this split core current transformer option to monitor the consumption with;
Consumption Monitoring CT
For use with XAM1-120, split-core current transformers enable whole home consumption
metering (+/- 2.5%).
I don’t have a use for this yet but I thought others might.

For a less expensive option that is accurate enough to get the basic idea of energy flows, there is the ENVI PowerSave home energy monitor: WWW.powersave.us <http://www.powersave.us/> ,

I use the egauge a lot. Although it is not circuit specific, you can tell from the profiles what is taking power. You have 12 inputs so you can use it on 12 circuits instead of just the overall service.
If you buy 50A CTs they are pretty cheap.
The Homeplug adapter makes getting the data to the internet very easy.
I don't think you will find anything cheaper and easier.Â
I have a spare unit I keep as a site assessment tool. Even though we have a Fluke 435 Energy Analyzer, the egauge is better for longer period assessments.
Also, you can cascade them so if you have two panels in different locations you can use one as an input to the other.Â

HI All.
I’ve been getting a bunch of requests for better monitoring of AC circuits, and I want to be able to understand some peoples loads better as well.
This is for a full house 120v and 240v
And
individual circuits.
I don’t need revenue grade.
But looking for something that is easy to use, maybe blue tooth app, or digital display with memory ( day/week/month would be good)
Could be internet connected but not a priority.
I’ve seen some for $40-80.
There are so many out there I figure someone/s have got some fav’s.
thanks
jay
