I would like to use the BMV relay to drive the Multiplus.

Hello
I have a smart BMV-712 and a Multiplus24 | 5000 | 120 - 100 | 230 / 240V.
I would like to stop the battery discharge to 40% to 50% maximum.
I would like to use the BMV relay to drive the Multiplus.
It's possible ? and how ?
Thank you

Yes, this is possible.
Use the "Two Signal BMS Support" assistant to do this. Set it up so that "BMS has one contact which switches on low cell condition".

This will hve the effect of disabling discharge when the BMV relay contact closes.

Here is a link to the Assistants manual:

I have the VE-configure3 software, normally it's ok.
I will connect two wires on BMV712.

But I do not know
where to connect these wires to the Multiplus?

Hello,
The update is OK!
very easy to do.
But obviously this is not possible with the latest firmware,
it looks like it is incomplete or missing something ... and the multiplus is too old.
We had to tinker with a configuration of different "wizards" and do several tests.
But the bmv 712 driver Multiplus well with these assistants.
Thank you !
Thank you Victron France ;)
