Charge Controllers and Max Array Watts

I am looking to add a 3rd array to my system. I have 10 Trina 250 watt panels available. I currently use 2 FM60s on my other arrays and have a Mate3 for monitoring/programming. The specs for the FM80 I am looking at, say max array is 2000 watts and max amps are 80.The panels are rated at 8.85amps short circuit current which would exceed the 80amps. I planned to have 5 strings of 2 panels each to come in at 44.25amps. But the array wattage would still exceed the 2000 specified. Would I be safe in going foward?
