You can use the current MP to do that. Configure 1-phase generator to L1 and adjust settings that In the case of phase two and three failure, the Master will continue charging the battery.

Hi, according to the VE.Bus system configurator turtorial, this should be possible:

I have never tried that by myself, but it would not be in the turtorial if it would not work ;o)

Hi, would that work in combination with a three phase ESS? The three phase generator is the grid. The fourth Multiplus would be connected to an additional 1phase AC source, eg a generator. This generator is only used in case of a grid failure and no PV available. Battery is LFP (so with BMS). Do I need an additional GX Device for the 4th Multi or can it be handled by the existing GX used for ESS?
