Xantrex MPPT Charge controllers

Sorry Flats but most CC made for 48 volts are going to be 45, 60, and 80 amps. At least any worth having.

AS mentioned in a couple of other threads, I have an XW6048 inverter (6000 watts continuous/120/240V), grid tied, with battery backup. I currently have an Outback FX80 CC and I just tried looking up a Xantrex CC so the CC and inverter can communicate with each other. Since the battery backup portion of my 6.32 KW array is only 1480 watts worth (The rest is grid tied only using a Fronius 5000 watt inverter), I don't need as large a CC as I originally planned. I seem to only find 60 and 80 AMP MPPT charge controllers by Xantrex. Does Xantrex make any smaller charge controllers that are MPPT? If yes, please give a model number and/or source. It seems I'd only need a 30A CC. My system is on a 48V battery bank.
Thanks,
Dave
