Need advice on setting up a system

Currently I have 4x12v 100w used solar farm panels with 8 6v 215 ah batteries @ 12v and a makeskyblue 60 cc. I have recently upgraded my panels to 12x24v 345w Hanwha Q Cell 345 Watt Poly, reliable 24v 3000w 6000 peak inverter, still using the makeskyblue 60 cc and the 8 6v 215 ah batteries in parallel and series at 24v. I know I need to get more batteries. Should I upgraded the cc to something that can handle the solar panels or get multiple cc? Currently only using 1k every 30 hours but I will be adding a split AC unit.
