Output current of the Classic 150

I am designing an off grid solar setup utilizing the classsic 150.  I will start with two strings of 3 each cs6x295m Can Solar solar panels, and plan to add more string(s) later.   Therefore, my input voltage will be approx 110VDC @16A peak.  I will be charging two 250AH AGM batteries in series for a 24V system.  From there I power an Aims 24V to 120V MSW inverter.  My question is, I see that the classic 150 outputs a maximum of 84 amps at 28.7 volts charging with a properly sized array (I know I will be less than that for my starter Panels I am using).  What happens to the controller when the inverter is drawing a severe load of lets say 150amps from the batteries.  Assuming my small arrary can supply say 1500watts to the controller, can I assume that the controller will add approximately 1500watts or so to the battery circuit during the 150amp loading???   I would guess that a fully charged battery would drop down in voltage during loading of 150amps.  It seems hard to predict what would happen here.  Any help or thots would be appreciated..

You are spot on say for example the Classic has 1500 watts of panels available and it is in Float using 100 watts to maintain the batterys when the 150 amp load kicks in the voltage will sag and the Classic will give the other 1400 watts to power the load.
