How to read direction of Current, with SCT013-100

Tags: #<Tag:0x00007f1d5b05ea68>

Hello good evening, I do not know how to make the SCT read negative values, and know the direction of the current, I have solar panels and I would like to be able to see this value, but the polarity that I put the clamps always gives positive values, The measurements they are correct in terms of magnitude.
thank you very much greetings
I attach a photo with the sketch and the arduino schematic

thank you very much

You can never know the “direction” of current flow, because it changes direction 50 times per second. Only the power flow has a direction, and you need to compare the current against the voltage instantaneously to calculate that.

You must read this page in the ‘Learn’ section:
Learn→Electricity Monitoring→AC Power Theory→Introduction→An Introduction to AC Power

Thank you Robert, I got it.
