So could someone explain proper connection for a single phase home but where the PV system is setup for 220v? Meaning do we just clamp 1 CT to 1 of the hots, or around both, or something different? Thanks!
Hi:
This is the wiring diagram.https://www.iammeter.com/docs/wiring-diagram#21-install-2pcs-wem3080
The CT is clamped on one wire(hot wire), please note there is a direction (K->L) requirement on the CT.
Thanks for the repaste. I see the diagrams, and they are great! However I always have doubts in my head.
I think I have single phase.
Grid:
2x 120v inputs. 1x Neutral
Solar PV:
2x leads across both bars (220v), 1x neutral
I have a wem3080T
--------------- Grid power ----------------------------------------------------------------
If I put 1 CT on 1 of the inputs it shows "125v".
--- wont I only be seeing the power usage on one of the bus bars? (1 of the 120v inputs) instead of both?
Should I put 1 CT on the one input, then the 2nd CT on the 2nd input?
---------------------------------------------------------------------------------------------
---- PV system -----------------------------------------------------
Ok so that leaves me 1 CT.
The PV system has a connection to both bus bars, inputting 220v
If I put the 1 remaining CT on 1 of the PV wires, will I only be getting half the information?
---------------------------------------------------------------------------------------------
Sorry to make you spell it out. Hopefully whatever you do answer helps others too.. :)
