Ignore the SOC readings they are only based on voltage and thus inacurate.
Once the solar had gone to bed, the 25.95 volts, almost 13 volts per battery, is about right for a charged AGM.
Set the Equalise duration to zero.
Noise from the battery seems odd. Try the charge ( boost) volts at the slightly lower setting 14.4 x2 , 28.8 volts.
If you are following the charge process, ( assume the battery pack has been discharged), the voltage should rise to the charge target, 29.2 or 28.8 , whatever was set, hold this for two hours with gradually falling current, then drop to float volts, 27.6 volts.
There must be enough solar for this, solar Input volts needs to be a few volts higher than battery volts.
As discussed, ignore the battery SOC, its incorrect.
