How do I find the right Victron MPPT charge controller for my modules?

To design and select a Victron charge controller, it is best to use the Victron tool MPPT charge controller calculation, which you can download here:

You can create your selected modulethere by entering the current and voltage data of your module there and creating everything under the name of your module.
Now you can see, for example, whether you can place more than 8 modules per string on the MPPT 450/100 Tr.

In terms of power, this MPPT can process around 6 kWp (5.8 kW max. charging power).
Now you would have to divide the modules accordingly.
