Integrating non Victron RV-C MPPT with Cerbo

I am working with a client who already has two factory installed Future Solutions MPPTs. I will be installing new batteries, SmartShunt, a Multiplus, a Cerbo and Touch 70. The MPPTs have RV-C output. I have read in the manual that the Cerbo will receive and display data from these controllers. I understand how to do this according to the manual but am wondering if anyone has any specific experience with integrating non Victron MPPTs using RV-C.
