A three-phase inverter is a type of solar microinverter specifically designed to supply three-phase electric power. In conventional microinverter designs that work with one-phase power, the energy from the panel must be stored during the period where the voltage is passing through zero, which it does twice per cycle (at 50 or 60 Hz). In a three-phase system, throughout the cycle, one of the three wires has a positive (or n
