Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the utility model discloses a one-stop photovoltaic inverter, which comprises a cabinet body 1, wherein grooves 2 are formed in two sides of the cabinet body 1, a vent hole for installing a fan 4 is formed in one groove 2, the other groove 2 is communicated with an inner cavity of the cabinet body 1 through a through hole 7, square annular fixing edges 3 are formed in the two grooves 2, filter screens 5 are arranged in the two grooves 2, sealing plates 6 for sealing the grooves 2 are detachably connected to the cabinet body 1, and through holes 7 are formed in the surfaces of the sealing plates 6.

Specifically, a baffle plate 8 for dividing the inner cavity of the cabinet body 1 into two cavities is arranged in the cabinet body 1.

In this embodiment, one of the two cavities is used for installing components such as a heat exchanger and a power module, and the other cavity is used for installing control components such as an ac contactor and an ac output circuit breaker.
