Am I able to charge a 48 Volt battery bank (Four 12V batteries connected in series) with two 12 volt solar panels with a 75/15 MPPT charge controller in between?

No, the MPPT controller is a Buck converter not a Boost converter. It cannot "step up" the PV Voltage.
PV Voltage must be higher than the battery Voltage.
