The equalization voltage must be lower than boost or equal to it. in most cases it is better to have the equalization voltage lower.
READ MOREMost chargers are CC (constant current) / CV (constant voltage) chargers set at 3.6-3.65v. When this voltage is reached the amperage of the charger declines rapidly and stays low for the final 15-30min of the charge. This final phase of the charge could be considered similar to an absorption/float stage.

If you are trying to fully charge/float on a Growatt with AC current, you can''t. Set 13 to 3.55V/cell and you''ll get close to fully charged.
READ MOREI have set the absorption-voltage now for my 48V-Lifepo4 on 56,8V and activated the setting "keep the battery full loaded" in the ESS (GX-Touch). Slowly increase the float-voltage up to 56,8V the next days so that the balancer has a chance to balance all cells (top-balancing) and after this setting absorption/float on 56/54V.

(that is 3.525V per cell and is a bit on the high side 14.00 would be better) Float at 13.70V (we do not need to float these Litium Iron Phosphate batteries)
READ MOREI have two 51.2v 200AH LiFePO4 batteries from a DIYer. The maximum recommended voltage 57.6v. He recommends setting both Absorption and Float Voltages at 55.6v primarily to prevent one battery from charging fully and the charging current feeding into the other battery. Victron recommends 56.8v for Absorption and 54v for Float.

(Normal charging is to 60%, fast is to 90% ultra fast is up to 97% SOC CC) I guess most use fast charging. CC is called "boost" charge. Absorption I don''t know, but overall advice is not to use for LiFePO4. CV then should be float.
