Hier das Beispiel (ich hab das damals nicht selbst erstellt sondern von den Werten her nur angepasst)
Den unteren Teil mit der Relaissteuerung vom RS450/200 kannst du ignorieren. Das steuert bei mir den Remotekontakt meines dreiphasigen Solax X3 12K wenn der Akku 100% erreicht hat. Im Frühjahr hatte ich noch kein Vertrauen zu der Frequenzregelung des Solax und wollte ihn sicherheitshalber "hart" ausschalten wenn der Akku voll ist.
Nachfolgend der JSON Code den du einfach als Flow importieren kannst. Nach dem Importieren den Teil "Switches SOLAX X3 ON..." einfach entfernen.

. Sie wird sogar über Stunden massiv überladen. Ich empfehle dringend das Victron ESS Handbuch, das Handbuch des Cerbo GX, und das Handbuch der Laderegler zu lesen und zu verstehen.
