Solar pannels for AC 200Max plus B230 Combo

I originally bought the PV200 to power up my EB70 but now have the AC 200Max and the B230 combo, and would like to know what the best course of action would be for charging my combo unit using my current PV200 and some other solar panel(s) PV350 whatever.
I run 50 feet of MC4 10Gage cable if that makes a difference, and taking into consideration a parallel or in series connection.
Any ideas?
