On our Yacht we have added a 100/500 controller to our new array (600w) and using the existing smaller MPPT to control a 150W array.
Initially I had a VE Smart network, but now I have VeDirect cables connecting both controllers to the CerboGX.
Do I need to do any configuration in the Cerbo GX to set this up for best efficiency?
Do I need to delete the VeSmart network?
It's a good idea to remove the smart network to avoid conflicts. Depending on your setup, you can look at enabling DVCC for coordinating charging.
(the cerbo guide has a good section on this)
