[0023] like Figure 2 and Figure 4 As shown, a plurality of square through holes 16 are penetrated through one side wall of the two square grooves 11, and a filter plate 17 is fixedly connected inside the plurality of square through holes 16. A cooling fan 18 is fixedly connected to the two side walls of the inner part of the grid-connected box body 1. By setting the filter plate 17, moisture and dust in the air entering the grid-connected box body 1 can be filtered, so as to prevent the internal components from being affected by water and dust and improve the service life of the internal components.
