Abstract
A voltage compensation apparatus, an inverter apparatus, and a photovoltaic power generation system. The system includes a photovoltaic panel string and an inverter apparatus. The inverter apparatus includes an inverter and a voltage compensation apparatus. One pole of a power output terminal of the voltage compensation apparatus is coupled and connected to an N wire in a power grid. In this way, the power output terminal of the voltage compensation apparatus can be directly coupled and connected to the N wire in the power grid, to form a power compensation loop, and there is no need to form a power compensation loop based on a grounding wire of the inverter. Therefore, an electric shock risk that exists when a person unintentionally comes into contact with a housing of the inverter can be eliminated.
