Exterior battery box disconnect

[Spacecoast Solar]

I plan to install a grid tied system using Outback inverters on E-Panels and a charge controller.  Equipment to be installed inside an exterior garage with a 48 volt battery bank of FLA batteries in a battery box on a slab on the outside of the garage.  This installation is located in Florida, so no possibility of freezing.  To comply with NEC 690.71(H) I must have the 48 Volt battery bank switched at the equipment and the source as well as the source being fused.  I could have a 125 amp breaker(Midnite Solar MNEDC-125) that would satisfy the switch & fuse but there is no NEMA-3R enclosure available for that breaker.  Blue Sea battery switches do not meet code for residential applications, they are for marine use.  What can I use to switch 48V @ 125 amp in a NEMA-3R enclosure?  here is the code:http://www.jade1.com/jadecc/courses/UNIVERSAL/NEC05.php?imDif=790.0

Thanks Doug, but those are for interior use, I need something rated for exterior.
