Everything is easy - the second time you do it. Equalize those batteries.

It is pretty easy to do! Will be super easy the next time! This is using the Outback FM80for the procedure.
Went with 60.2 volts for two hours. Could have gone higher, maybe would have gone higher but running AGMs - that can be equalized. I'm certain the AGM's caused much of the hesitancy about equalizing.

Then I overslept and missed any gains noted in AM voltage. I often measure battery bank strength partly by the voltage displayed prior to sun up charging. May not be the most scientific but it is done every single day. Lets me know of significant issues.
If my batteries discharge by 20% daily they will survive for much longer than a 33% daily discharge. Though pros are rarely happy unless they can complicate things to the degree that others decide the pros are needed. True in every niche that pros may be found.
Think I'll try 61 volts for two hours next time. Their bulk and absorb recommendation is 58.8 - pretty high. I had a few weeks of low voltage last summer - until the system failed for a day.
