Could someone experienced the fact that the external current sensor disable the battery discharging ?
So no power feeding from battery if current sensor is used (ie. To monitor power from another inverter)
asked
Why no battery discharge when external current sensor AUX1 is connected ?
@nostromo I had the same issue. It took me weeks to find the answer. In short, there is a setting in VE configure (added after a recent firmware update) that allocated AUX1 to a grid demand interlock. You have to disable this in VE configure but if you have applied a county specific grid setting toy uor VE configure files, you'll need a password from Victron to disable this setting should you want to use AUX1 for the CT sensor.
See below link.

Hi Jason, I applied your method and it work.
Thanks a lot for support. I really appreciate.
FYI: External sensor assistant don't work after soft reboot of the unit. You must absolutely do a hard reset via ON/OFF button (It’s the case on my unit). I pass hours to find this tip :-)
Best regards.
Can I've the password to change the parameter AUX 1 as disable Feedin signal ?
Best regards
@nostromo
I am not able to provide you with that (for legal reasons) since for some it is grid code and therefore compliance related.
For the rest aux is alternatively programmed through assistants and does not need a code.
I understand the legal raison, but this do not solve my problem. Please give me a detailled procedure (Legal) to get Battery discharged when AUX1 use current sensor.
"alternatively programmed through assistants" is not sufficient as support.
Best regards.

See controlling depth of discharge.
Controlling depth of discharge have nothing to do with the problem regarding AUX 1 power sensor witch desable discharge of the battery.
So, no solution yet.

Hi Matthias, I used AUX 2 ans also T° imput, same effect. See my answer to Jason about that problem (Solved).
Thanks for trying to give info.
Best regards.
Did you try
@Jason - UK suggestions? And do you have ess and a grid code installed? Soes the CT really need to be plugged in if it is the thing giving you the problems?
Solution of Jason is working. I don't understand your question about sensor. For sure sensor have to be plugged.
