Schneider sw4024 charging 24V 3.8 SimpliPhi

I have a schneider sw4024 inverter charger that is connected to a 24v 3.8 simpliphi battery. I have all the protections in place for overvoltage charge/discharge etc.
My question is this: when I am charging my my battery via generator backup, the the charging logic starts charging the battery at 22.5 amps then when it reaches bulk at 27.2 it increases the amps to 45 for 60 min. (Voltage stays at 27.2). Is this normal? I am use to seeing a higher amperage at the beginning of the charge cycle and reducing as it finishes the bulk (at 27.2).
Any help would be appreciated.
Thank you

What you are saying does not make sense.
Check the settings and make sure you don't have some interaction with AC loads. If you only see it on generator then there may be a problem with generator overloading. Set your AC2 (gen) max input AC current to about 75% of generator maximum continuous amperage limit. On inverter if AC max input is reached it will override charger settings if they are set higher then can be supported by AC input limit.
So when it starts charging in bulk, it charges at 22.5 amps. Even if I have charge rate set at 100%. When it goes to absorb it jumps up to 45 amps. The only thing I can think of is something wrong with the software maybe?
Did you install the equipment and program the inverter yourself? Is there similtanious solar input and if so are the charge controller settings the same as the SW?

Lead Acid batteries need to hold the charging setpoint for 2-6 hours or so (deeper cycle, longer absorb cycle) to fully recharge. Lead Acid batteries are only ~80-90% full when the charging setpoint voltage is reached (depends on charging current, etc.)
Anyway--No expert--But that is how I understand the reasoning.
