Multi RS speist ungewünscht ins Netz ein

Hallo Community,
meine neue Anlage besteht aus einem Multi RS und einem 15kwh-Speicher von Gobel mit einem JK-BMS.
Der RS steht durch das automatisch erkannte BMS auf “Externe Steuerung” und die Laderegelung wird durch die Vorgaben im BMS gesteuert.
Das System soll so arbeiten, dass es den PV Strom in die Batterie lädt oder selbst verbraucht. Eine Einspeisung soll nicht stattfinden!
Die PV hat den Speicher nun das erste Mal voll geladen und die PV Leistung wurde mit erreichen der für eine Vollladung eingestellten Zellspannung seither vollständig ins Netz eingespeist.

Meine Frage: Welche Einstellung verhindert, dass die PV Leistung ins Netz abgegeben wird?
Mein ESS hat lediglich 3 Einstellungen. ESS-Modus, Mindestentladung und Netzsollwert.

Vielen Dank für Eure Hilfe. Fragen zur Konfiguration beantworte ich sehr gern (kann aber auch mal ein paar Stunden dauern ;-))

Hello community,
My new system consists of a Multi RS and a 15 kWh Gobel storage system with a JK-BMS.
The RS is set to “External Control” due to the automatically detected BMS, and the charge control is controlled by the BMS settings.
The system should operate by charging the PV power into the battery or consuming it itself. Feeding into the grid is not allowed!
The PV has now fully charged the storage system for the first time, and since then, the PV power has been fully fed into the grid once the cell voltage set for full charge has been reached.

My question: Which setting prevents the PV power from being fed into the grid?
My ESS only has three settings: Mode, Minimum Discharge, and Grid Setpoint.

Thank you for your help. I’m happy to answer any questions about the configuration (but it might take a few hours ;-))

In the Grid settings of the RS6000 you can disable Feed-In.

If I deactivate the feed-in in the grid settings, the load on the other phases is no longer balanced.
Then it draws energy from the grid.

How many Multi RSes do you have?
From the first post one may believe that only one…
Then why talking about other phases not being balanced ?

Do you have a Grid Meter and Support for it enabled in Victron connect? Does Limit Feed-In to 0 Change the behaviour?

@ Alex Pescaru It’s just one grid-connected system, and I want to use ESS and PowerAssist to balance the other three phases of my house and keep them at 0W.
This works as long as the battery is charging. When it’s full, the PV energy isn’t “discharged” but goes fully into the grid.

@ aaxc I connected the vm-3p75ct via VE.Can, and limiting it to 0 means that the load on the other phases is no longer balanced by the battery or PV.
For this to happen, the RS must “feed” into one phase until the total load of all phases reaches the set grid setpoint.

Maybe I am wrong, but are you sure this is how it supposed to work?..
Isn’t the RS supposed to compensate the phase on which is connected and not the other ones?

@ Alex Pescaru Yes, I’m sure that’s how it’s supposed to work, and it does :wink:
That’s the Power Assist function.
The available energy is used both to balance the AC load and to charge the battery.
The desired AC target load can be set via the grid setpoint (currently 10W).
Unfortunately, this value is ignored once the battery is fully charged.
Until then, everything works perfectly.
