24V Panels to 12V bank SmartSolar using MPPT 100/50

I have 4-12v solar panels planning to run series-parallel pairs 24v into my SmartSolar MPPT 100/50 and out to 4-12v 200Ah AGM battery bank.

This is for an RV boon-docking setup and I will be using my existing 12v 3000W inverter for now. So until I upgrade, is there anything aside from less overall efficiency I am missing or should be concerned about with this setup?


thanks in advance for any input!

The only thing is that you must not exceed a voltage of 100V on the input of the MPPT100/50 (that's what the 100 stands for), even under worst conditions (panels cold and no load at all). So if you wire the panels 2x2 everything is ok.
