[0029] The preferred embodiments of the present application will be described in detail below with reference to the drawings, so that the advantages and features of the present application can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

[0030] Referring to Figures 1 to 5 The present embodiment provides a photovoltaic inverter system, which comprises a photovoltaic inverter 1 and a wall hanging device 200. The photovoltaic inverter is a 6-10KW energy storage grid-connected machine, and the weight is about 30kg. Further, the photovoltaic inverter 1 comprises a box body 13, and the back of the box body 13 is provided with an inductance box 11 and a radiator, wherein the number of inductance boxes 11 is multiple, and the inductance boxes 11 are arranged above and / or below and / or on the left and right sides of the radiator.

[0031] Specifically, in this embodiment, the inductor box 11 includes a first inductor box 111 and a second inductor box 112. A heat sink is disposed between the first inductor box 111 and the second inductor box 112. The first inductor box 111 is located above the heat sink, and the second inductor box 112 is located below the heat sink. The outer contours of the first inductor box 111 and the second inductor box 112 are substantially flush with the outer contour of the heat sink. It should be noted that the "up" and "down" directions here refer to the vertical direction after the photovoltaic inverter is suspended on the wall. Figure 3 The up and down directions are shown in the diagram.

[0032] At least two first inductor boxes 111 and / or second inductor boxes 112 are provided with hooks 2. Specifically, in this embodiment, the first inductor box 111 has three independently provided hooks 2, which are spaced apart on the box body 113 of the first inductor box 111. (Refer to...) Figure 2 As shown, the hook is L-shaped, and the area or space occupied by the hook 2 is small, saving manufacturing costs. The hook 2 can be set only in the middle of the inductor box or at both ends of the inductor box. The number and position of the hooks are not limited here. Compared with the design of a whole hook in the prior art, the hook 2 in this embodiment can save manufacturing costs. Furthermore, the hook 2 and the box body 113 of the inductor box 11 are integrally set, and the material of the hook 2 and the box body 113 is metal. It is not necessary to set the hook separately on a mounting plate, further saving usage costs.

[0033] Furthermore, the hook 2 is used to mount the housing 13 onto a wall-mounting device 200, which is fixedly connected to the wall. The wall-mounting device 200 has slots 203 for inserting multiple hooks. Specifically, in this embodiment, there are three slots 203 and three hooks. The hooks are located in the middle and at both ends of the first inductor box 111. In other embodiments, hooks may only be located in the middle or at both ends of the first inductor box 111. The slots 203 and hooks are positioned in a one-to-one correspondence. During assembly, the photovoltaic inverter is lifted and moved from top to bottom until the hook 2 is inserted into the slot 203. The photovoltaic inverter and the wall-mounting device are then assembled, making the operation relatively simple.

[0034] Combination Figure 3 and Figure 4As shown, the photovoltaic inverter 1 further comprises a shell 3 and fans arranged in the shell 3, the number of the fans is two, and the two fans are arranged side by side in the up-down direction on the shell 3. The fans, the radiator and the inductor box 11 are arranged on the back of the box 13, and the air outlet of the fan faces the radiator and the inductor box 11. Further, the first inductor box 111 (only the hook 2 on the first inductor box 111 protrudes out of the shell) and the radiator are arranged inside the shell 3, and the second inductor box 112 is arranged outside the shell 3, and the air outlet of the fan faces the radiator and the first inductor box 111. It can be understood that the shell 3 has a heat dissipation channel, and the fan sucks the cold air from the outside into the inside of the shell 3, and the cold air passes through the radiator and the first inductor box 111 to dissipate heat for the radiator and the first inductor box 111. Compared with the inductor box and / or the radiator directly exposed to the outside of the box, it can play a role in concentrating heat dissipation, and the heat dissipation effect is better.

[0035] Further, the shell 3 is provided with an air inlet side 31 and an air outlet side 32, the air inlet of the fan faces the air inlet side 31, the shape of the air inlet side 31 is basically the same as the outer contour shape of the fan, and the air outlet side 32 is correspondingly provided with a plurality of air outlets, the shape of the air outlet is a long strip, which is not only distributed on the opposite faces of the fan, but also a plurality of air outlets are arranged at the upper end of the shell 3, that is, heat can be dissipated from more air outlets, further enhancing the heat dissipation effect of the photovoltaic inverter. That is, the photovoltaic inverter of the embodiment has good heat dissipation effect.

[0036] In combination Figure 4 and Figure 5 As shown, the photovoltaic inverter 1 further comprises an anti-theft device 4 arranged between the wall hanging device 200 and the shell 3, and the anti-theft device 4 is specifically an anti-theft lock. The wall hanging device 200 is provided with a first mounting hole 204, and the shell 3 is provided with a second mounting hole 33. During installation, the anti-theft device 4 passes through the first mounting hole 204 and the second mounting hole 33 to prevent the box 13 and the wall hanging device 200 from being separated. Since the photovoltaic inverter 1 of the embodiment is provided with an anti-theft lock, after the hook on the inductor box 11 is inserted into the slot 203 of the wall hanging device 200, it is not necessary to use screws or other fasteners to further lock the photovoltaic inverter 1 and the wall hanging device 200, while ensuring that the photovoltaic inverter also has the function of anti-theft, reducing the installation process, and being convenient to install and use.

[0037] In combination Figure 1As shown, the wall-hanging device 200 comprises a wall-hanging plate 201, a slot 203 and a first mounting hole 204 are arranged on the wall-hanging plate 201. The wall-hanging device 200 further comprises a mounting plate 202 for fixedly connecting with the wall 100, the mounting plate 202 is fixedly mounted on the wall through a plurality of screws 205, the wall-hanging plate 201 protrudes relative to the mounting plate 202, a gap for inserting the hook is left between the wall-hanging plate 201 and the mounting plate 202, the mounting plate 202 and the wall-hanging plate 201 are integrally arranged and the included angle between the mounting plate 202 and the wall-hanging plate 201 is 75-95°.

[0038] When the photovoltaic inverter 1 of the embodiment is mounted on the wall 100, the wall-hanging device 200 is first fixed on the wall 100 through the plurality of screws 205, specifically, the wall-hanging device 200 is fixed on the wall 100 through the mounting holes on the mounting plate 202 of the wall-hanging device 200, then the photovoltaic inverter is lifted and moved from top to bottom until the hook on the first inductance box 111 can be smoothly hung in the slot 203 of the wall-hanging plate 201, finally the anti-theft lock is sequentially inserted through the first mounting hole 204 and the second mounting hole 33 to lock the box body 13 on the wall-hanging device 200, thereby enhancing the anti-theft function.

[0039] The photovoltaic inverter of the embodiment has at least the following advantages:

[0040] (1) The hook is integrated on the inductance box, thereby reducing the manufacturing cost;

[0041] (2) The box body of the photovoltaic inverter has a shell to form a heat dissipation channel, thereby having a better heat dissipation effect;
