MPPT online calculator says max output current 80A for SmartSolar MPPT RS 450/100

I'm playing with https://mppt.victronenergy.com and I'm confused because it somehow says

MPPT max. output current 80 A

for the SmartSolar MPPT RS 450/100. Why is that? I couldn't find the 80A anywhere in the data sheet.

One tracker can max. 80A. Add a 2nd tracker and you see 100A max. and 80A max. per tracker.

Okay, that's a bit weird since 4000W does not equal 80A, there's a voltage involved, too. But at least it sheds a light on why that number is there. Thanks.

Work on a charging voltage of 50V to get the 4000W. In practice it will depend on the battery SOC. But it's a 4000W unit.
