PHOTOVOLTAIC POWER CONVERSION DEVICE

Embodiments of this application provide a photovoltaic power conversion apparatus. The photovoltaic power conversion apparatus includes a first housing, a power component, at least one second housing, and at least one wiring terminal. The first housing forms a first accommodation cavity, and the power component is fixedly disposed in the first accommodation cavity. The at least one of the second housing forms a second accommodation cavity, and the at least one second housing is disposed outside a connection area of a first side wall of the first housing by using an installation wall. The wiring terminal sealingly penetrates through a part of the connection area of the first side wall, a first end of the wiring terminal is located in the first accommodation cavity, and a second end of the wiring terminal is located in the second accommodation cavity. The first accommodation cavity and the second accommodation cavity can form cavities that respectively meet sealing protection requirements, so that components in the first accommodation cavity and the second accommodation cavity can be independently protected.
