   yep. Also if the second controller was MPPT that should be fine too. You just don't want two different types of solar modules feeding into one MPPT controller. Everything else should be OK. 

The battery is a voltage source/sink so will establish the voltage that both controllers see. Depending on what each ones setpoints are one controller will cut out and/or in sooner than the other but that won't cause any issues.
