You got it. That is what the charge controller does. It converts the panel string voltage to what is needed by the battery
. Just make sure the charge controller has sufficient amps to cover your needs.
For victron the the first number is the max panel input voltage and the second number is the charge controller amp output. So a Victron SmartSolar MPPT
100/50 means it can handle panel strings up to 100 V and output to the battery
a max of 50A. For the size of your proposed system I would go with MPPT
not the cheaper and less efficient PWM.
