Not if the panels are wired in series, as input voltage would be approximately 96 volts. #10 can do 30 amps. Thicker from controller to battery bank is a good plan.
There does need to be a disconnect switch, rated for direct current, between the panels and the controller.
Since AGM does want a "wake up" charge at high amperage, more wattage may be desirable, or at least a way to charge each battery individually to keep them "happy".

For that many amps coming from the solar panels, you will need at least 4 gauge wire or larger, or you will be losing a lot of power due to heat dissipation. Make sure the solar charger has a four-stage "smart" converter to charge the batteries. If you only have 2 12V AGMs, then a couple hundred watts is certainly enough, unless you run your TV and heater all night...and all day...
