Technically Yes. A single-phase inverter will work on a 3 phase. This is thanks to the
way meters instantaneously calculate grid consumption and solar production as a
combination of all three phases. But because of the increasing issue of voltage
rise, we always recommend using a 3 phase inverter when you have three-phase
power. This will not only help with voltage rise and the inverter tripping out
but it will mean you can install a larger inverter and a bigger solar system.
