Whats the recommended way to connect these?
My thoughts atm are:
MPPT directly to Pylontech, VE.can to Cerbo gx
Pylontech to Quattro and ve.bms to Cerbo gx.
Quattro via VE.bus to Cerbo gx (get error see other topic)
Any suggestions?

Best practice connect: Pylontech, MPPT VE.can, Quattro(140A), Cerbo GX
In the end I used Bush bars as this is recommended although I never was quite clear why exactly even in this specific case.
Hi @Hans
I personally go all to the GX device, but I think this link explains it for you:
The pylontech to quattro might be the cause of your other errors.
ah yes thank you I was wondering if a bushbar is needed a pylontech has 2 - and 2 + i was thinking 1 to Quattro and one to the MPPT.
All communication is going trough cerbo gx atm
Oohh sorry i assumed communication.
I imagine you can get away with that however I believe most people use additional busbars rather than using pylontech essentially as the busbar.
I was scrolling through this to see if there was a concrete example, couldnt spot anything but might be useful

Use of a bus bar is best practice.
It allows better current sharing in the install.
Ease of connection and cable routing. No lug stacking. Neater install. Easier to remove or add components without disturbing the rest that is working.
Individual fusing is easier too.
