Please find below an image of the correct port setup for a standard Solar PV monitoring system using a CM180i transmitter for the Intuition-pv product (these are not relevant for full 3 phase installations)
Please also note port 3 is never used in a standard PV installation
The Left hand wire monitors consumption, the right hand wire (in the middle port) monitors Solar Generation. the 3rd port should be empty
If you are not sure which cable is which for your particular installation just place the two cables as shown above. Then with your Owl dashboard view open, turn a kettle on and you should see aft,er a short delay that your electricity display values will rise sharply.
If this is not the case and the Solar values rise , please swap the two cables around
