Get Multiplus II running

Hello dear community


I have my system 80% completed, now I wanted to get my 3 Victron Multiplus 2 48/3000 to run in 3 phase operation as a test, but there is only voltage on the AC out 1 output. Mains voltage is present at AC in and is also recognized correctly.


What am I doing wrong ??

What do the inverters absolutely need to feed in on the AC in?

if there is no external grid, the inverters will never feed in to ac-in. AC-In is used for grid feedin and also for ess.

As an island system you have to use ac-out.

How are they connected?

Do you have a GX? Do you have an mk3?

Is the battery bank shared?

Have you read the manual?

The 3 Mulitplus are connected via VE.Bus to a Cerbo GX which is supposed to control everything. I also have an MK3 for programming.

The Multiplus are already configured for 3 phases.

I also have a smart shunt for the batteries because my BMS doesn't want to communicate with the Victron systems.

It's a grid system that I want to build, so the Multiplus should feed into the power grid, but for reasons that I don't understand, this doesn't happen.

Da Du Deutscher bist antworte ich mal auf deutsch: Du hast keinen ESS Asstistenten geladen. Somit funktioniert auch keine Einspeisung. Das ist des Rätsels Lösung !
