I have a Shelly EM50 and have just noticed that the readings seem to be backwards.
The total energy shows 0.17kw and the total returned energy shows 24.24kw.
I am not returning any power to the gtid?
Any ideas?
The CT polarity is incorrect, swap it at the EM’s terminals.
They plug in? They don’t wire in.
The CTs have a 2 pin plug
Just open the clamp, rotate 180deg and clamp it again.
Ah I think that did the trick.
Thank you!
You’re welcome.
Current transformer doesn’t care about direction or if the direction is defined as export or import.
It just outputs negative for one direction and positive to other.
0.17kwh vs 24.24kwh . Either you are really using everything you product or your inverter is set for zero-export.
