Hi,
For a specific application we are investigating the possibility of having 6 parallel MultiPlus 2000 without having a battery. The idea is to distribute a big AC load between 6 MultiPlus, each of which receives a separate input AC line (say, an input AC socket, a Generator, etc.).
Would it be possible to do that? any idea or help is appreciated.
Thanks
@golanbari Victron systems require batteries and should be configured as per below. Anything else would not be supported and also invalidate any warranties.
No. The AC inputs and outputs of all units must be connected together. The input to the cluster must be from the same source. Nothing else will work. You also need a battery.
In order to do what you want, you'd need separate AC to DC chargers on each source then a fairly large battery bank. The outputs of the Multis would then be connected together but without an AC input.
Paralleling 6 units would be a challenge since all cables (DC and AC) need to have matched lengths. This is discussed in the webinar/traning for parallel and multi-phase system design. It's available on professional.victronenergy.com. Best have someone with tons of parallel systems experience help with design and implementation.
You say you want to parallel 6 2000 VA Multis. That's a total of 12 KVA which could be handled by a single Quattro 15K (230 volt only). You still need a battery bank. You still won't be able to connect multiple AC sources . You still need to go with the multiple AC to DC chargers connected to the battery.
