Currently have a 30a MPPT w/ 2 200w panels. I want to add a 60a MPPT w/2 200w panel and 4 100w panels to the same array. besides the data comm cable do i need anything else to add the additional MPPT to the system?

Hey Michael, welcome back. Since you're running two separate solar charge controllers you'll need the Go Power Solar Cable Entry Plate with Red and Black MC4 Cables - 25' Long item # 34273843REVA to connect your new panels to the 60a MPPT controller. If you want to run your charge controllers in parallel you'll also need the Go Power Parallel Cable for MPPT Charge Controllers item # GP89QR.
I recommend using butyl tape and some sealant for the brackets and drill holes to ensure proper water sealing which you can find together with the Item # 344270KITW kit.
