Three-phase generator and single inverter

Hi,
I am developing a project for an offgrid industrial warehouse. Yhey had a 30kW three-phase generator. The owners want to install photoovltaic panels, victron inverter and battery for single-phase consumption. They ask me if it is mandatory to buy three inverters to connect in three phase and parallel way. We wanted to avoid having a phase that was more unbalanced than the others. Can it be regulated in some way, without having to buy 2 more inverters? Is there a VICTRON product that converts three-phase to single-phase?

You should be able to install an inverter/charger on just one (or two) phases of a three-phase system. Note that the other phases would be powered by the generator without aid from the inverter/charger.

There is no simple way to convert three phase power to single phase. This is generally done with a three phase motor coupled to a single phase generator. To do it electronically, you would need to convert the three phase AC to DC then use a single phase inverter to make single phase AC power from the DC. You could combine Victron chargers, a battery and a single inverter to accomplish this but there is no single product.
