Bulk to Absorb repeat

[ClassicCrazy]

In addition to what Vic said - if they are brand new batteries you may want to check manufacturers recommendation for breaking them in . You may have to cycle them very deep for some amount of cycles to get them to work their true capacity . 
Tuning the SOC to be accurate also takes some careful observation - it is just an estimate and can change depending on other circumstances might not always be 100% accurate.
I understand what you are thinking - the PV can put out a lot of amps and it would be great if the batteries just sucked it all up when available. But lead acid batteries don't work like that - the charge current tapers off quite a bit when it gets up like 92% full and gets into Absorb .  That is why lots of people use the Aux relays to control loads and turn things on to make use of extra available power that the batteries can't absorb.
The exception is lithium batteries - depending on the actual type of lithium you can dump lots of power into them until they are full . But that is a whole different story .
