I have a new install with the F3600 Inverter. Prior to the install I had 365W x2 = 730W Panels Offgrid which I wanted to have combined with the new install of 8x390W = 3,120W panels.

I have been advised that its not possible to connect both arrays because the panels are not identical, however wanted to check if it would be possible to install these via the 2 PV inputs on the inverter, or do both of the PV inputs need to be idential?

Any help / advice appreciated.

Sadly not, 2 panels wouldn’t be enough to get over the minimum startup voltage (120v) on a single string, ideally you would want a minimum of 5 panels - can you purchase 3 more similarly rated panels
