Dear community. I am planning to get a CT (the blue one, by YHDC).
Do I need to change any settings to activate it? In particular, do I need to install the Current Sensor assistant on the Quattro-II and/or check the external sensor checkbox in VEConfig?
I am unsure, as there isn't much in the docs - and not even all pictures of the Quattro-II show the necessary (3.5mm) socket. Some pictures do, and there it is labeled "Current sense".
However, there is a Current sensor documentation which says "This AC Current sensor (CSE000100000) should not be confused with the specific Current Transformer 100A:50mA accessory for MultiPlus-II (part number CTR110000500)." https://www.victronenergy.com/live/ac_current_sensor:start
So is this a completely different beast? Or just the same thing by different producers, the Sensor for the old MP/Quattro, the CT for the MP-II/Quattro-II? Victron seems to sell both.
Is the blue one connected and configured the same way as the Victron current sensor?
According to https://community.victronenergy.com/questions/107502/ve-configure-external-current-sensor-connected.html
it says there is an option "External current sensor connected" box in VEConfig, but adds "This option is only for the optional current transformer."
However, in this video https://www.youtube.com/watch?v=xHQGOfSGQd4 it says at 2:10, that for the Cerbo it is not actually an "external" sensor, so in the Venus ESS settings it should not be set as such. So external for VEConfig, but internal for Cerbo... o...k....
And, finally, this answer https://community.victronenergy.com/questions/81289/multiplus-ii-ct-ac-current-sensor-assistant.html suggests that one shouldn`t even set the checkbox in VEConfig, contradicting the comment two links above.
So what is correct?
