How does a 3 Phase quattro deal with a lost supply phase?

Hi . What happens if the mains supply to a 3 phase ( 3 x 5 KW) quattro loses a phase?

Does the whole system change onto battery, or will it continue charging off 2 phases and give a normal 3 phase output?

The whole system will switch to inverter mode.

Thanks Matthias. So in Inverter mode, will the 2 quattros that still have mains supply keep topping up the battery?

If all three are in inverter mode the quattros will be disconnected from the grid as described in this thread.
