Nested Multiplus with Venus OS

I have a dual nested inverter setup.

The big inverter is a quattro 48/5000 which runs everything in my RV. It has ve.bus to a raspberry pi running Venus OS, and a Smart shunt on 3x 51.2v system.

Also running off the above victron, is a AIMS 1200w inverter that charges the house batteries and if the victron fails, powers the TVs and refrigerator.

After being very pleased and impressed with the victron setup, I want to replace the AIMS with a Multiplus 12/1200 with ve.bus and connect it to the raspberry pi

First, with ve.bus, do I need another USB dongle? It can I plug the 1200va ve.bus into the same dongle or the quattro? Not a big deal.

Second, how will the Venus OS screens handle the second inverter (Multiplus) which is actually running off the quattro?

Hi, they can't share a common vebus.

On a cerbo you would use the native vebus and add a mk3 (it is a documented setup), so presumably two mk3's on a Pi (though I don't know if the OS has an issue with that configuration, not tried it myself).

On the Cerbo, the internal vebus has priority and the mk3 is secondary.

Venus will ignore the second inverter, it will not be used for management or native reporting, but it will appear in the device list, but not on the console or VRM dash.

Advanced widgets can be added, or nodered used to generate charts.
