Rainwater enters the water storage tank 3 after being filtered by the strip filter 5 of the rain and snow protection slope cover 2. When a thicker layer of snow accumulates on the top surface of the rain and snow protection slope cover 2, the electric heating wires 11 built in the plurality of convex ribs 4 are started to work, so that the heat generated by the electric heating wires 11 is transmitted through the plurality of convex ribs 4 to the inverter body 1. The ribs 4 are transferred to the snow layer of the rain and snow proof slope cover 2, so that the accumulated snow layer is melted and filtered and collected in the water tank 3, which minimizes the erosion and backlog of the inverter body 1 caused by rain and snow. When it is hot, the rain and snow water collected in the water tank 3 are poured into the two groups of water pipes 8 on the left and right sides of the inverter. With the start-up of the cooling fan 9 on the surface of the metal mesh 7, it is easy to blow the cold water in the water pipe 8 to the inverter body 1 through the air blown by the cooling fan 9, so as to cool the inverter body 1 in hot weather and achieve the effect of collecting and reusing rain and snow water.
