[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] In a home energy storage system, the inverter is responsible for converting the DC power from the energy storage battery into AC power required by household appliances. For safety and aesthetic reasons, the inverter is usually installed inside a decorative enclosure. However, since cables may need to be routed from different directions in actual construction environments, multiple cable trays are typically created on the side wall of the decorative enclosure to accommodate diverse wiring needs and achieve standardized production. While this improves installation flexibility, it increases the risk of external dust and other debris entering the enclosure and also affects the appearance of the home energy storage system. In this embodiment, a limiting hole 111 is provided on the inner wall of the cable tray 11 of the enclosure 1, and a sealing part 2 with a protrusion 21 is provided. During installation, simply align the protrusion 21 and insert it into the limiting hole 111 to seal the unused cable tray 11.

[0018] Please refer to Figures 1 to 3 As shown, the present invention provides an inverter decorative cover, including a cover body 1 and a sealing part 2; the side wall of the cover body 1 is provided with a cable outlet groove 11, and the inner wall of the cable outlet groove 11 is provided with a limiting hole 111; the sealing part 2 is used to cover the cable outlet groove 11, and the sealing part 2 is provided with a protrusion 21 that matches the limiting hole 111.

[0019] Working principle: A limiting hole 111 is provided on the inner wall of the cable outlet 11 of the cover 1, and a sealing part 2 with a protrusion 21 is provided. During installation, simply align the protrusion 21 and insert it into the limiting hole 111 to seal the cable outlet 11. This not only effectively prevents external dust and debris from entering the interior of the cover 1 from the unused cable outlet 11, but also maintains the shape of the cover 1, thus ensuring the overall aesthetics of the home power supply.

[0020] In some implementations, please refer to Figure 2As shown, the sealing part 2 is an elastic sheet, and the sealing part 2 has an operating plate 22 that abuts against the inner wall of the cable outlet groove 11. The protrusion 21 is disposed on the operating plate 22. Since the sealing part 2 is an elastic sheet, pressure can be applied to the operating plate 22 to cause the sealing part 2 to bend to a certain extent, thereby allowing the protrusion 21 to move in and out of the limiting hole 111.

[0021] In some embodiments, the sealing portion 2 is provided with a ball screw, and the protrusion 21 is the steel ball on the ball screw. Since the steel ball of the ball screw can move along the length of its own screw, the protrusion 21 can be operated to move in and out of the limiting hole 111 by pushing the sealing portion 2.

[0022] In some implementations, please refer to Figure 1 As shown, the bottom of the enclosure 1 is provided with a cable inlet slot 12. The cable inlet slot 12 facilitates the electrical connection between the control box 3 of the home power supply and the inverter inside the enclosure 1.

[0023] Please refer to Figure 4 As shown, this utility model provides a home power storage system, which includes an electrical box assembly, a control box 3, and an inverter stacked sequentially from the ground upwards. The inverter is housed inside an inverter decorative cover, which is the inverter decorative cover described in the above technical solution.

[0024] Working principle: During the assembly process, the electrical box group is first stacked and assembled on the ground, then the control box 3 is assembled on top of the electrical box group, then the inverter is assembled into the enclosure 1, and then the enclosure 1 is assembled on top of the control box 3.

[0025] In some implementations, please refer to Figure 5 As shown, the bottom of the cover 1 is provided with a support block 13, the support block 13 having an insertion interface 131, and the support block 13 having a first mounting hole 132 located at the insertion interface 131; the top of the control box 3 is provided with a positioning block 31 adapted to the insertion interface 131, and the positioning block 31 having a second mounting hole 311 adapted to the first mounting hole 132. During the assembly process of the cover 1 and the control box 3, the positioning between the cover 1 and the control box 3 can be completed by inserting the positioning block 31 on the control box 3 into the insertion interface 131 of the support block 13 of the cover 1, and then the first mounting hole 132 and the second mounting hole 311 are connected by screw threads, thereby connecting the cover 1 and the control box 3 together.

[0026] In some embodiments, the positioning block 31 is frustum-shaped, with the upper base area being larger than the lower base area, and the lower base area of ​​the positioning block 31 being connected to the top of the control box 3. The positioning block 31 is configured in a frustum shape to facilitate its insertion into the connector 131.

[0027] In some implementations, please refer to Figure 6 and Figure 7 As shown, the electrical box assembly comprises multiple stacked electrical boxes 4. Each electrical box 4 includes a box body 41 and an end cap 42. The box body 41 has a slanted opening on one side along its width, causing the width of the box body 41 to gradually increase from top to bottom. The box body 41 has an outwardly flanged edge 411 along the contour of the slanted opening. The end cap 42 has a sealing frame 421, which seals the slanted opening through the cooperation of the sealing frame 421 and the outwardly flanged edge 411. By setting the opening of the box body 41 as a slanted opening, allowing the box body 41 to gradually increase in width from top to bottom, and by setting the outwardly flanged edge 411 along the contour of the slanted opening, space is created at the top of the box body 41 for the bottom outwardly flanged edge 411 of the upper stacked boxes 41, thus reducing the distance between the upper and lower boxes 41. Simultaneously, the end cap 42, through the cooperation of the sealing frame 421 and the outwardly flanged edge 411, assembles an annular sealing gasket to ensure the airtightness of the electrical box 4. This structure not only ensures the cell capacity of the original battery box 4, but also reduces the spacing between adjacent battery boxes 4, improving the overall compactness of the stack.

[0028] It is worth noting that the assembly between the upper and lower electrical boxes 4, as well as the assembly between the electrical box 4 and the control box 3, can also adopt the assembly structure between the cover 1 and the control box 3 described above.

[0029] Specifically, during the assembly of the upper and lower electrical boxes 4, the positioning of the upper and lower boxes 41 can be completed by inserting the positioning block 31 on the lower box 41 into the insertion interface 131 of the support block 13 on the upper box 41. Then, the upper and lower boxes 41 are connected together by connecting the first assembly hole 132 and the second assembly hole 311 with screw threads.

[0030] During the assembly of the electrical box 4 and the control box 3, the positioning between the box 41 and the control box 3 can be completed by inserting the positioning block 31 on the box 41 into the insertion interface 131 of the support block 13 of the control box 3. Then, the box 41 and the control box 3 are connected together by screw thread connection of the first assembly hole 132 and the second assembly hole 311.

[0031] In some implementations, please refer to Figure 7 and Figure 8 As shown, a limiting block 5 is provided between the outer flange 411 and the sealing frame 421. The limiting block 5 is used to control the distance between the outer flange 411 and the sealing frame 421, that is, to control the thickness of the compressed annular sealing gasket set between the outer flange 411 and the sealing frame 421.

[0032] It is worth noting that the limiting block 5 can be the round head portion of a rivet screw used to connect the outer flange 411 to the sealing frame 421, and the limiting block 5 can also be a gasket welded to the outer flange 411 and / or the sealing frame 421.

[0033] The thickness of the limiting block 5 is B, which is 2mm to 3mm. B includes, but is not limited to, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, and 3mm.
