A solar photovoltaic three-phase micro-inverter (200) comprises: a direct current terminal (201) connected to three direct current photovoltaic components (202) adjacent to one another; three single-phase inverter circuits (203), having input ends connected to the three direct current photovoltaic components (202) respectively through the direct current terminal (201), and used to respectively convert direct currents generated by the three direct current photovoltaic components (202) to alternating currents; an alternating current terminal (204), connected to a three-phase alternating current power grid (206). Respective output end of each single-phase inverter circuit (203) is connected to one phase (L1, L2 or L3) among the three phases of the three-phase alternating current power grid (206) and a neutral line (N). A solar photovoltaic power generation system (500) is also provided. The three direct current photovoltaic components (202) connected to the three-phase micro-inverter (200) are adjacent to one another, and therefore, the illumination, temperature and other environmental conditions thereof are similar, so that the phases of the three-phase alternating current are balanced. |
