So, it looks like you have a 24 V system, and 60-cell PVs. In general with this solar panel type, there is often not enough input voltage to allow full charge of batteries, with most charge controllers like the Outback (MPPT ones) when using a 24 V (or 48 V) battery.
We know almost nothing about the details of your system. What is the type of battery on the system, or better yet, what is the manufacturer and battery model number for your battery bank.
The Default charge voltages and charge time are usually not appropriate for Flooded batteries (ones with caps on the top of batteries that are easily removable.
Thanks for the added info. Vic
