Can MP-II's AC-out-2 be programmed to have power when grid fails?

I found this in MP-II documentation:

Auxiliary AC output (AC-out-2)
Intended for non-critical loads. Default behaviour only allows AC-out-2 after a 30 second delay when AC input is detected. A Current measurement circuit enables PowerAssist. Override programming for more control of this relay is possible.

Where I can find something about this "override programming"?

You have to use the "programmable relay" assistant.

Yes, mine stays on until 70% SOC then switches off. So you can have it quite flexible.

@Alexandra

Thank you both for this info. I suspected that this "programmable relay" has interesting features but documentation on it is scarce.

Since you know so much about the Victron systems maybe you can suggest the solution to my other problem I posted on the forum here.

Thank you in advance.

The possibilities with the "programmable relay" assistant are nearly endless so it would be impossible to make a documentation about that.

Just use the "fake target with full options" function of VE.Config and take a look at the options.
Sometimes you have to play around a bit to get it working like you want it.

I did not look into it closely maybe because the name "programmable relay" is not very "interesting". :)
