Can you connect to 2 Multiplus's to a shared Battery / BMS. Obviously possible for Parrel and 3 phase set up, but can they work standalone sharing a battery and BMS?
As and example.
8 x US2000C
Multiplus II 3000 230V
Multiplus II 3000 120V
1 X Cerbo GX
The AC side would be completely separate (except Earth).
Only one of the MultiPlus' can be part of the system and have its energy flows counted.
The other one can be connected to the CerboGX with a MK3-USB dongle but it will only show up in the menus for casual observation of its data. Its energy will not be counted in the system, it will not be visible in the graphical pages nor in VRM dashboard.
If only your earth will be shared how are you separating the neutrals from earth? How are you ensuring that there will never more than one neutral-earth bond at any one time?
OK thanks, does the standalone unit still repect the BMS, i.e. low battery stop inverting?
In the example above there would be no AC in on the 120V so both L and N would be from AC Out and efectively off grid.
