Hey all -

I have to credit Amos at Zonna Energy  who provided the following procedure for upgrading a Radian GS4048 to a Radian GS8048.

If you want to change a GS4048A to a GS8048A, add second power module & you also need to change a setting in the inverter and change it to a GS8048A
Go to ;  Lock>Up>Installer> Enter installer Password 1732>Settings>Inverter>Model Select and spin wheel to select the correct model.

Thank you Amos!
