AC Current sensor giving the wrong value

I have a 3-phase ESS-system with an AC-coupled PV-system.

I am using 3 AC current sensors ( https://www.victronenergy.com/meters-and-sensors/ac-current-sensor), connected to the temp-inputs on the Multiplus'es to show the values from the PV-system.

The problem is that my Victron system gives me way to high values.

In this very moment, my PV-inverter is producing 14200W, but according to Victron its about 21200W.

How can I calibrate this?

There is the problem, manuals says 1,2,3 on for 7kw not 4 :)

Are they setup right? Dipswitches set right? Wired right?

There normally are not very accurate/slow but this is a bit to much

I hope so. The dipswitches are all set to 7kW (no. 4 on, rest off) as my total solar is about 20kW.


Wiring should be correct aswell.

I havent really found any other settings for these, are there?

Yes! That was it. I missunderstood this image and had it set up the exact opposite :)
