One phase grid to three phase distribution

I have one phase 230V grid. Three phase Multiplus output. 48V battery pack.

Grid serves as battery charger only through multiplus when voltage drops below 45 volt.

I get phase rotation warning every time when grid supply is needed.

I have connected 1 phase grid to AC input of each Multiplus.

Can the grid supply be used to charge the battery pack when connected to L1 Multiplus only because in my setup it doesn't work due to rotation warning?

Thks

With L1 connected to each Multi you don't have the phase shift that is needed for a 3 phase system so you get an error.

With the "VE.Bus System Configurator" and the option "Switch as group" you should be able to connect the grid to only one Multi.
