New Victron LFP installation constant switch between bulk and absorption

Hi!


I have a new LFP system with with Quattro 48/5000/70-2x100 and 4*Smart Lfp 25,6 200Ah. What I see when charging is the system only switches to absorption for a short time and immediately back to bulk, never to float. Is this normal or expected? The charger voltages are the default from the Quattro. Thanks

From where are the batteries charged, from grid?

When this behaviour happen, constantly switching from Bulk to Absorption,, are the battery almost full (over 90%SOC) ?

I see no alarms online in VRM

Yes, this is how the voltages and current look like.
