Can this charge controller and panels work 🤔

Hey guys,
I am wondering if my maths is correct. I have a Victron 100/50 charge controller in a 24v configuration. It’s max PV input voltage is 100v and max PV short circuit current 60A. 1400w nominal PV power for 24v.

I am eyeing 4 APTOS 370w byfacial panels (DNA-120-BF26-370W) in a 2s 2p configuration. The panel specs are 370w, open circuit VOC 41.4v and short circuit current 11.26. A theoretical 1480w max.

So my math is two sets of panels in parallel [11.26 + 11.26] 22.52a + [11.26 + 11.26] 22.52a then joint them in series which [41.4v x 2] 82.8v.

The 22.52a is below the 60a max for CC and the 82.8v is below the 100v max for the CC 🤔

This seems to fit with in the specs of charge controller. Am I missing something here. Am I calculating correctly. Most importantly can this work safely. FYI in live in the tropics warm to hot weather all year round, so cold weather is not a factor.
 
If it’s easier - join to panels in series first, then connect those two in parallel- that way you only have one parallel combination point.

Your setup is about ideal for that combination- the math is correct.
