i didn't have any trouble getting the CTs over my 100AMP lines, they are aluminum but I don't know the size, I just know they cover them easily. They most definately do not fit over the 200 AMP coming into the service panel. I'll take some pictures and post up tomorrow.
You don't need a wifi on the EmonTX as it will talk to EmonPi via RF.. but that is ok.. wifi is probably more reliable and less prone to interference. I just haven't used wifi on the EmonTX.
I currently read just one of the hot lines coming in from my array and double it but the readings from the microinverters and the CT do not match up as closely as I'd like. again this system is open so if I see that all I need it to increase the reading by, say, 3% I can put that in to the calculations from the INPUTS to the FEEDS.
Best guide was here https://guide.openenergymonitor.org/setup/
and setting up the inputs and feeds helped a lot here https://guide.openenergymonitor.org/app ... stallation
for the solar part.
this needed a reading too https://guide.openenergymonitor.org/set ... h-america/
the guy mumbles a lot so it can be hard to hear him but I'm more tuned into it than most since I'm British anyway. Things to remember.
1. EmonPi is powered by the USB 5v unput, not the AC adapter, that is just for reading the power.
2. Switching off the emonPi is done by pressing in the little peg indented that you can reach with a pencil and only unplug the power once it says so.
3. it can take up to 2 mins to fully boot up.
4. I created an account on my emonpi and created the very same username and password on the emoncms.org for simplicity, they don't have to be the same but I did that.
5. if you screw up it's ok, you can start over again as the inputs are automatically recreated for you so you can get going again.
6. watch all the videos and read the guide as you go.. read over it a few more times if you don't get it and read over and over it if you don't seem to be getting the results you expect.
There was a couple of things not matching from the guide and video but I got through it and now I'm little more comfortable than I was the very first time I switched it on and was wondering what it was all about. I'm no geek.
I might just get my system and reset everything back to stock empty and go over everything i did and record it. I don't know. I might have enough spare time.
