Nube here - Which controller should I use?

Hi all. Brand new to the community.

I am installing a total of 8 385w Jinko panels. Originally, I had planned 2 strings, each in a series-parallel connection. I had planned on using 2 250/60 controllers.

Then, someone told me I could go with a 150/85 for each string if I wired each string in parallel.

My panels:

Vmp - 40.8v

Imp - 9.45a

Voc - 49.1v

Isc - 9.92a

Device rating- 20a


Any suggestions?

Thx!
