Thanks for your reply Iwsmiser. Yes my system does perform very well and has done for many years.
I am new to IotaWatt and would like to be able to measure my consumption and visualise it on the same graph (PV Output) as I visualise my generation (production) on.
I have not yet set up the CT placing and configurations as I would like to learn how it all “works” first.
So, my initial setup is that I have ONE CT, plugged into the IotaWatt, and configured to monitor my main AC supply. i.e. consumption.
Don’t care about gross or net at this stage, I just want to measure (and graph) whatever current (power) flows thru that conductor.
I want to be able to graph whatever happens on that conductor, base consuption, turn the kettle on, whatever.
When the sun is shining and I am generating, I expect to see reduced or even negative current flows thru the conductor that I have my ONE CT on.
Pretty basic at this stage, but that is how I learn.
Now I want to be able to get this “consumption” data onto my “generatiion” graph, showing up in red.(default?)
And as long as this “consumption” is less than my “generation” the (red?) lines and areas on the graph will be less than and lower than the green lines and areas of my generation.
You can see from the screen shots that I posted, for some reason the “consumption” is getting ADDED onto my “generation”
Obviously a simple configuration error.
This is my query
ps. the single CT that I have connected is actually connected to the inverter output (active). Two reasons for this.
that conductor is easily accessible
the data resolved by that CT will be very close (but NOT identical due to % margin of error of the CT) to the power that is reported by the inverter directly. This will make the 2 data sets displayed on the graph basically overlay each other nearly identically with the difference being the error between the two readings.
this setup is just for testing purposes only at this stage.
