Single phase system to 3 phase system using Victron Multiplus-II

Q&A and troubleshooting

Hi community,

I have a question regarding the possibility of creating a 3 phase system output by installing 3xMultiplus-II 10000/140 but having just one single phase grid. I found something similar archived and the solution was to disable some sync feature from the config and connecting the single phase grid only to the master inverter.
But i have a concern, is the phase-phase voltage 380V or still 240V at the output of the inverters?

I am not sure if this was answered and i was not able to find it, if so please let me know and i will close this question.

IF its possible (at all) then the converters should run in WYE-config, with common neutral, as starpoint.
NOT in Delta-config.

This means the phase-neutral voltage would still be 230VAC (220VAC).
Phase-phase voltage would be 400VAC (380VAC).

But this means one of the leads of your mains single-phase should be neutral. NOT split-phase AC, where there is 110VAC from each lead to ground.

This is what i found. nd i am very courious if it is working and that the Phase-Neutral Voltage is 230VAC and Phase-Phase is 400VAC. Anyone used this kind of setup?

This is from Victron manual: Parallel, split- and three-phase VE.Bus systems [Victron Energy].

I guess nobody did it so far, commenting for the algorithm.
