If you want help with that, you should post a link to the sensor.

Google will open your mind.
Also note that the 712 is used inline of the load power line not across it.
There is diagrams in that PDF.
Then it seems that the 712 just outputs an analogue voltage based on current draw that you measure on any A2D input.
Please take care and know what you are doing. My solars deliver s/c current of 8.7 Amps and have an o/c voltage of 525 vDC. That stuff kills.
