A three-phase solar inverter takes DC electricity from solar panels, chops it up and sends it out as AC electricity shared across a three-phase supply. DC in. Three-phase AC out. They cost about $300 more than the equivalent single-phase solar inverter, but look the same: If it is a 3-phase Fronius it will say ‘Symo’ on it.
If you have three-phase supply you can have either: Any of these choices are valid. It will not affect how you are billed for exports or how much solar energy is self consumed. But, I still recommend a three-phase solar inverter.
