摘要：A solar photovoltaic three-phase micro-inverter comprises: DC terminals, coupled with three DC photovoltaic assemblies adjacent to each other; three single-phase inverter circuits having input terminals coupled respectively with the three DC photovoltaic assemblies via the DC terminals, for converting the DC currents generated by the three DC photovoltaic assemblies to AC currents, respectively; AC terminals coupled with a three-phase AC power grid; wherein output terminals of each single-phase inverter circuit are coupled respectively with a neutral wire and one of the three phases of the three-phase AC power grid. A solar photovoltaic power generation system is also provided. The three single-phase inverter circuits can be integrated as above Because the three DC photovoltaic assemblies on one three-phase micro-inverter are disposed adjacently and have similar environment conditions, such as illumination, temperature, etc., the three-phase AC current can be well balanced.
