Multiplus set to ignore ac in until SOC hits 70%. Response stagnates. Why?

img-2723.pngI have a multi 12/3000/120, BMV712, Cerbo and GX display, 680 watts of solar and 4 Victron MPPT controllers. I have programmed the inverter to “dedicated ignore ac in” until SOC is less than 70%. For the past two day the system has consumed battery power til 70 % but lingered here often turning on the charger in float for a brief time until finally turning on the full charge cycle starting in bulk. I am trying to avoid the long period of cycling at 70-72%. Suggestions?

How do you have it programmed? Have you added sustain on?

No. Sustain is not on. As I understand sustain, it will manage the battery charger but 120 ac is still used to pier ac needs. I want to minimize all ac power usage.

Please see the attached for details of configuration. On the Victron Cerbo the Multiplus is chosen as the battery monitor. screenshot-2023-11-25-at-42719pm.png
