So I can connect one array with 450 to MPPT 1 and another with 450 to MPPT 2? Concerning Amps, I believe the correct function is for the Inverter to draw the power it requires while keeping the Voltage at bay. As long as the voltage is correct, having 14 A may not affect the inverter.

If you have the Pylons connected to the Sunsynk, then the only setting you need to do is the Ah on the Battery page (74Ah in your case). The inverter will get all other data directly from the BMS. You can check everything by going the the BMS page in the Sunsynk menu

Thank you very much, i have done all the wiring haven't connected anything , will post the results. 

I have to ask another question: where did the 450v value come from? Per the link I posted MPPT limit is 425v and max DC is 500v. @WannabeSolarSparky posted the current rating per MMPT has been raised to 13A (have you got a published datasheet for that?), on that basis, has the MPPT voltage been raised too and do you have this current/latest firmware? (don't assume your new unit has the latest firmware)
I personally would not take a chance on current - why publish a max value if you can exceed it? At least contact the chaps and Sunsynk before you make an expensive mistake. Bear in mind current is often limited by the size of the contacts. conductors, etc i.e. hardware.
