Connecting different systems with different voltaje to the Venus GX

I have a main system at 48V (MPPT Bluesolar 150/60, Multiplus 48/5000/70, BMV-700 and Venus GX) and another small 12V system on the side with a Victron Phoenix 12/375 inverter. I would like to monitor that system too. Is it possible to connect this unit to a port on the Venus GX to read its data remotely or will that confuse the whole 48V system?

I do not think, that adding a 2nd BMV from another system to Venus is a good idea.

Maybe consider to change the BMV 700 to a 702 and monitor the 12V system as a "starter battery"

Yes, I thought about that option too. All I really wanted to do was to remotely access the inverter, but that could perhaps mix up things for the main system.

As a suggestion: Get a Raspberry Pi for that and make a whole separate system. It would be a cheap solution.

That is true, thanks , that sounds like a fun assignment!

You will wonder, how easy this will be set up.

1.) get a Pi

2.) Flash SD card with Venus Image

3.) connect LAN and VE.direct

There is plenty of documentation available online.

But I don't know, if your smaller inverter is fully compatible with Venus yet. Make sure to check that first.
