Dear Victron Community,
I have a question about the configuration options that I am sure only Victron can answer directly.
I will soon have 4 Multiplus 48/5000 - I would like to create a 3-phase ESS from 3 of them - the fourth should be connected but switched off by default.
The plan is to run this either as a backup (there are several Victron systems in my circle of friends) or as a charger in the event of a mains failure with an emergency generator.
There is also a Cerbo-GX and several Pylontech US5000s.
Using the 4th Victron as a normal charger (without connection to the Cerbo and without connection to the BMS seems to work without any problems in principle.
Now I have found the following in the VE-Configure-Tutorial:
"Part 2: 3 phase system with 3 phase AC input and single phase AC input; steps 13-22"
There is also an entry on this in the German-language photovoltaic forum, but no solution.
Can I program the above tutorial into the Victrons (3x AC input 1 & switch as group and 1x AC input 2 not switch as group)? In this case, can I connect an emergency generator to the 4th Victron (no grid connection) and leave it switched off by default or will this not work? The advantage would be communication with the BMS and that the Cerbo would know all the components.
Many thanks for your help
