For maximum results the 100 and 200 panels in series must have the same amp rating ie Imp. For the 2 parallel strings the 2 strings should be same voltage ie Vmp. Best to use the same panels.
MPPT does convert the panel voltage/amps (power) to the battery voltage/amps. The problem with a mismatched parallel pair is he loss of overall power.
Find out how your contoller handles more that 1450W. Mine limits the amps when over panneled. Plus you are not likely to ever reach the maximum watts as a bright clear day with the panels pointed directly at the sun is required. So depending upon the over panel answer add 2x 200W OR a second controller with 400W.
