How does a 3 phase solar inverter work?

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.

Can a 3 phase inverter power a 10kW Solar System?

In the energy system’s eyes this is still an inefficient solution as the solar power cannot directly optimise across phases. If phase B draws 10kW then a system with three single phase inverters must draw power from the grid, while a three phase inverter 15kW inverter could tackle the entire 10kW if there was no usage on phases A & C.

Do I need a three-phase solar inverter?

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.
