Abstract: Embodiments of this application provide an inverter apparatus and an inverter system. In the inverter apparatus, a direct current output end of an alternating and direct current distribution cabinet is connected to a first direct current input end of an inverter. A first alternating current output end of the inverter is connected to an alternating current input end of the alternating and direct current distribution cabinet, and the alternating and direct current distribution cabinet outputs a converged alternating current. In this way, on-site wiring is simplified, and on-site maintenance is reduced to some extent.
