How big of an MPPT do I need for 6 x 450w solar panels, 24v system?

I'm looking to add a second array to our home's 24v system. I'm buying 6 x 450w panels. What size MPPT controller do I need for this array? I'm not buying a Victron panel so I can't input the size of my panel into the MPPT calculator so I'm asking everyone instead. Please advise?

what are are you using in your first array?

6panel at 450watt is 2700watt / 24 volt is 112.5 AMP

you would need a mmpt charger capable of min 112.5 amps. that means big cables ...

or your run multible mppt controllers on different solarpanels with different settings for charging
