Multiplus with US3000A - Charging flaps between bulk and absorbtion during the night


We have an Easysolar 48V 5000W with two US3000A batteries (Pylontech firmware V3.4).
During the night the Multiplus Charger switches beween Absorption and Bulk as below.

What Multiplus Charger settings do we change to keep it stable at 52.4V, as is done by the MPPT Charging during the day?

Running ESS and with Keep Batteries Charged option.

@Deon

It is re bulking when the batteries request a bit of charge. They are probably balancing. Check the battery monitor widget for min and max cells.

I dont believe this is the case - cell voltages looks fine and this flapping has been ongoing for months.

Check the charge and discharge limits graph in advanced.

And the system should be set up as set out here.
