Three standalone multiplus with one batterie each and VE.bus for 1 or 3-phase output

Hi!

Can anyone guide me, is this possible?

I´m trying to create a system were all multiplus can run individual givining AC 1-phase output, and on rare occasion 3-phase output.

In this setup I´m thinking that the capacity and age of the three different battery banks doesn´t matter, witch gives me a larger range of use.

Of course I understand that the smalest battery will be the limitation, running 3-phases.

Thanx in advance!

To have a 3-phase system all MultiPlus have to be connected together and configured for 3-phase.
In this setup they should be connected to the same battery.

Dear El-Nisse

one battery in a 3 phase system means: put your three batteries in parallel to the multiplus system via a busbar (i.e. lynx power in)
In that configuration the battery with the lowest capacity does not limit the system. The three batteries act as “one”.

Have fun

Andy from the off-grid garage (youtube) shows this in his setup.

Actually it will work, but only as long as all mp are connected to the grid for frequency and phase synchronization. This way fi you could use power assist to drive a motor.

But when disconnected from the grid all will be chaos.
