Charging voltage fluctuating

Good day

I OPzV 200Ah batteries connected to my system.

During a charging cycle as soon as the battery approaches 100 % charge the charging voltage fluctuates between 55.2 V and 57.3 V *these values are set up as the float and absorption voltages). On the Victron itself the mode shows as 'Float'during the fluctuations. This does not seem normal ?

I am charging directly from the Victron Quattro unit (no MPPT).


Regards

Daniel
