What does it mean that our inverter is three-phase? If we want to make the difference between single-phase and three-phase inverters, then the first one is suitable for home use and must support low voltage. Opposite to that, three-phase systems are used in commerce and support higher voltages. Due to their higher power consumption, we will find three-phase inverters in commerce and industry.
Now, let's generalize: inverters convert energy captured into useful energy. Since three-phase inverters support high voltages, we can find them in business or industry.
