Batteries and CC vs Series and Parallel

Scottg4001

I am gathering new info everyday, so here is my next finding and question. I just found out that my AGM batteries can accept a certain maximum charge voltage or it will damage my batteries. The charge controller does regulate this voltage at 28.5 volts, which is perfect. If the battery charge is only requlated at 28.5 volts and I have a input voltage of 55 volts, is there any reason to even have a MPPT charge controller and is there any reason to have my two panels in series? If I can't boost the voltage for my batteries, whats the point? I am thinking of just going back to parallel, with a input of 28-29 volts and 14Amps with a standard PWM controller. Does this make sense or am I missing something?
