Modbus registers for more than one Solar MPPT

Good day,

We are trying to integrate our system containing multiple Solar Charge Controllers using Mod-Bus but are having some issues.

On the Mod-Bus codes for the PV chargers there is a note on register 776/777 saying it won’t work for multiple solar chargers.

Can Victron provide the registers for additional solar chargers or is there an overall value register where we can pull the total PV Voltage & Current or Total Power ?

Using register 789 PV Power only gives the power for one of the 3 solar chargers.

If you have multiple solar charge controllers, in Services - Modbus TCP - Available services, don’t you have multiple unit IDs, one for each solar charger?
Or is a single one that aggregates all?
