I am new to solar. I have been trying to make a decision on a 120v battery charger. I have an AGM charger that would charge the 100ah lifepo4 battery that i purchased. I understand why that this is not the best solution, however, could I connect the 14.6v output of my AGM charger to the solar input of my SmartSolar 100/30 to optimize the initial charging of the battery?

You should not connect a battery charger to the pv input to a mppt.
Besides the mppt needs pv input voltage to be at least 5v higher than the battery voltage for the mppt to start charging.
As with all batteries, follow the manufactures charging instructions. Maybe you could use the agm charger, but do check.
