Need help choosing a charge controller

I need help choosing a charge controller I have 8-195w panels connected in series/parallel for 48 volts (2 sets of 4 panels) and the batt bank is 4- 200 amhr AGM connected in parallel going to a 12v inverter. I am sure I want to go with the outback FM80 but not sure if the 80 amp will be enough or should I split the array and use 2 FM60's.

You might also consider the MidNite Classic 150 Charge Controller. Some info, here:
Microsoft PowerPoint - Classic (midnitesolar.com)
A bit more expensive, than the OB FM CCs, but much more flexible, and in a typical system, it can cost less, depending on the system requirements/design.
2 cents worth, Vic
