[0002] A photovoltaic inverter is an inverter that converts the variable DC voltage generated by photovoltaic solar panels into AC power at the mains frequency. It can be fed back to the commercial power transmission system or used by the off-grid power grid. It is one of the important system balancers in a photovoltaic array system.
[0003] Currently, photovoltaic inverters require installation structures for secure mounting, facilitating their combination with photovoltaic modules.

[0022] The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0023] Please see also Figures 1 to 6 One embodiment of this application provides a photovoltaic inverter assembly, which includes a photovoltaic inverter 10, a mounting component 20, a column 30, an adjustment plate assembly 40, and a plurality of threaded fasteners 50. The photovoltaic inverter 10 and the threaded fasteners 50 are commercially available products, and their principles and connection methods are existing technologies well known to those skilled in the art, and will not be described in detail here.
[0024] Mounting component 20 is installed and fixed to photovoltaic inverter 10, and column 30 is fixedly set relative to photovoltaic inverter 10.
[0025] The column 30 defines a hollow space 30a, and the adjustment plate assembly 40 is located within this hollow space 30a.
[0026] The column 30 has multiple mounting holes 30b that connect to the hollow space 30a, and the adjustment plate assembly 40 has multiple screw holes 40a. The multiple mounting holes 30b and the multiple screw holes 40a are all spaced apart along the height direction X of the photovoltaic inverter.
[0027] The number of threaded fasteners 50 is the same as the number of mounting holes 30b and is less than the number of screw holes 40a. Multiple threaded fasteners 50 pass through multiple mounting holes 30b and are screwed to multiple screw holes 40a.
[0028] The mounting component 20 is detachably mounted on the regulating plate assembly 40 so that the photovoltaic inverter 10 is supported on the column 30.
[0029] In practice, the column 30 can be fixed to a load-bearing structure such as a wall or bracket by means of bolts, but not limited to bolts. The adjusting plate assembly 40 is inserted into the hollow space 30a of the column 30 and fixed to the column 30 by multiple threaded fasteners 50. The mounting component 20 can be fastened to the photovoltaic inverter 10 by means of bolts, but not limited to bolts, to form an integral structure with the photovoltaic inverter 10. The photovoltaic inverter 10 is detachably mounted on the adjusting plate assembly 40 through the mounting component 20, so that the photovoltaic inverter 10 is supported by the load-bearing structure such as a wall or bracket.
[0030] When the cable connection position does not match the reserved connection position of the photovoltaic inverter 10, since the number of screw holes 40a on the adjustment plate assembly 40 is greater than the number of mounting holes 30b and threaded fasteners 50, the position of the adjustment plate assembly 40 in the height direction X of the photovoltaic inverter can be adjusted, and multiple threaded fasteners 50 can be tightened for installation, so as to change the reserved connection position of the photovoltaic inverter 10, so that the reserved connection position of the photovoltaic inverter 10 matches the actual connection position of the cable, thereby reducing the installation difficulty.
[0031] The specific structure of the photovoltaic inverter module mentioned in this application will be described below: For mount 20, please refer to Figure 2 In some embodiments, the mounting member 20 has a first hanging ear 201 and a second hanging ear 202 at its upper and lower ends, respectively. The first hanging ear 201 is detachably mounted on the top of the adjustment plate assembly 40, and the second hanging ear 202 is detachably mounted on the bottom of the adjustment plate assembly 40. For example, the mounting member 20 has an overall hollow bracket structure, with bolts passing through the sidewall of one side of the mounting member 20 and fastened to the housing of the photovoltaic inverter 10. Both the first hanging ear 201 and the second hanging ear 202 are approximately in the shape of a "7" hook, formed at the upper and lower ends of the mounting member 20 on the side facing away from the inverter. The first hanging ear 201 hooks onto the top of the adjustment plate assembly 40, and the second hanging ear 202 hooks onto the bottom of the adjustment plate assembly 40 to achieve stable installation of the photovoltaic inverter 10. A clearance space is provided between the first hanging ear 201 and the second hanging ear 202 to avoid obstructing the adjustment plate assembly 40.
[0032] For the adjustment plate assembly 40, please refer to Figure 5 See also Figure 2 or Figure 4 In some embodiments, the adjustment plate assembly 40 includes an adjustment plate 41 and a plurality of nuts 42. The adjustment plate 41 is disposed within the hollow space 30a, and the mounting member 20 is detachably mounted on the adjustment plate 41. Exemplarily, the cross-sectional shape of the adjustment plate 41 matches the cross-sectional shape of the column 30, and the cross-sectional shape of the adjustment plate 41 is approximately U-shaped. The adjustment plate 41 has a plurality of holes that penetrate the surface of the adjustment plate 41 facing the column 30 and the surface facing away from the column 30, and the plurality of holes are spaced apart in the height direction X of the photovoltaic inverter. The plurality of nuts 42 are all located on the surface of the adjustment plate 41 facing away from the column 30, and the plurality of nuts 42 are aligned with the plurality of holes one by one. A plurality of threaded fasteners 50 pass through the plurality of mounting holes 30b and the plurality of holes and are screwed and fixed to the screw holes 40a of the plurality of nuts 42, so that each sidewall on the adjustment plate 41 is respectively in contact with each side plate of the column 30.
[0033] Furthermore, multiple nuts 42 are fixed to the surface of the adjusting plate 41 away from the column 30 by riveting or welding. That is, multiple nuts 42 and adjusting plate 41 form an integral part. Compared with multiple nuts 42 and adjusting plate 41 being independent parts, welding or riveting can improve assembly efficiency and reduce errors caused by improper installation.
[0034] For column 30, please refer to Figure 3 and Figure 4In some embodiments, the column 30 has a first notch 301 at one end along the height direction X of the photovoltaic inverter, allowing the first mounting lug 201 to pass through the column 30 and be mounted on the adjustment plate assembly 40; the column 30 has a second notch 302 at the other end along the height direction X of the photovoltaic inverter, allowing the second mounting lug 202 to pass through the column 30 and be mounted on the adjustment plate assembly 40. For example, the column 30 is formed by continuous bending of a single piece of sheet metal, and its cross-sectional shape is approximately an open rectangular tube, defining the aforementioned hollow space 30a that extends vertically and is open on the side. The opposite ends of the open portion of the column 30 are fixedly connected by a bend. The first notch 301 and the second notch 302 are both approximately rectangular, and the first notch 301, the second notch 302, and a plurality of mounting holes 30b are all located on the side wall of the column 30 adjacent to the open portion. Along the height direction X of the photovoltaic inverter, the first notch 301 and the second notch 302 are located on the upper and lower sides of the area defined by the plurality of mounting holes 30b, respectively.
[0035] Furthermore, along the height direction X of the photovoltaic inverter, the distance between the first notch 301 and the second notch 302 of the column 30 is less than the distance between the two opposite ends of the adjustment plate 41. This arrangement ensures that one end of the adjustment plate 41 corresponding to the first notch 301 is exposed within the first notch 301, allowing the first hanging ear 201 to pass through the first notch 301 and hook onto that end of the adjustment plate 41 corresponding to the first notch 301. Even further, an opening 411 is provided at one end of the adjustment plate 41 corresponding to the second notch 302. Because the distance between the first notch 301 and the second notch 302 of the column 30 is less than the distance between the two opposite ends of the adjustment plate 41, the opening 411 can also be exposed within the second notch 302, allowing the second hanging ear 202 to pass through the first notch 301 and the opening 411 and hook onto that end of the adjustment plate 41 corresponding to the second notch 302.
[0036] Furthermore, the second notch 302, the first notch 301, and the multiple mounting holes 30b are all located on the same side of the column 30, and along the height direction X of the photovoltaic inverter, the second notch 302 and the first notch 301 are located on the upper and lower sides of the area jointly defined by the multiple mounting holes 30b, making it more intuitive to adjust the position of the adjustment plate assembly 40 in the height direction X of the photovoltaic inverter.
[0037] Continue as Figure 2As shown, to reduce the instability of the photovoltaic inverter 10 relative to the column 30 and facilitate the adjustment of the fixed position of the photovoltaic inverter 10 relative to the column 30, in some embodiments, the photovoltaic inverter 10 includes a fine-tuning bolt 61 and a fine-tuning nut. The fine-tuning bolt 61 passes through the column 30, the adjusting plate 41, and the second mounting lug 202 in sequence and is screwed and fixed to the fine-tuning nut. For example, the two side plates of the column 30 adjacent to the second notch 302 are provided with limiting holes 30c, the shape of which is adapted to the shape of the fine-tuning bolt 61; the two side walls of the adjusting plate 41 adjacent to the opening 411 are provided with elongated holes 41a extending along the height direction X of the photovoltaic inverter; the second mounting lug 202 is provided with through holes 202a passing through its left and right ends, the shape of which is also adapted to the shape of the fine-tuning bolt 61; the fine-tuning bolt 61 passes through the limiting hole 30c, the elongated hole 41a, and the through hole 202a in sequence and is screwed and fixed to the fine-tuning nut. In this technical solution, the presence of the elongated hole 41a allows for the change of the fixed position of the mounting component 20 relative to the column 30, enabling the overall adjustment of the photovoltaic inverter 10 relative to the column 30 in the height direction X. This adjustment is convenient and more precise.
[0038] like Figure 6 As shown, in some embodiments, there are two columns 30, which are divided into a left column 30 and a right column 30, and the left column 30 and the right column 30 are fixedly connected by a horizontal plate 31.
[0039] There are two adjustment plate assemblies 40. The two adjustment plate assemblies 40 are divided into a left adjustment plate assembly 40 and a right adjustment plate assembly 40. The left adjustment plate assembly 40 is located in the hollow space 30a of the left column 30, and the right adjustment plate assembly 40 is located in the hollow space 30a of the right column 30.
[0040] There are two mounting components 20, which are divided into a left mounting component 20 and a right mounting component 20. The left mounting component 20 and the right mounting component 20 are respectively installed and fixed at the left and right ends of the photovoltaic inverter 10. The left mounting component 20 is detachably mounted on the left regulating plate assembly 40, and the right mounting component 20 is detachably mounted on the right regulating plate assembly 40.
[0041] In this embodiment, the inverter is fixedly installed on the wall, bracket or other load-bearing structure by means of two sets of left and right columns 30, adjustment plate assembly 40 and mounting parts 20. This can effectively reduce the displacement or shaking of the equipment caused by vibration, external impact or temperature change. Furthermore, since the two left and right columns 30 are fixedly connected by the horizontal plate 31 to form an integral frame structure, the connection stability of the inverter is further enhanced.
[0042] In summary, the photovoltaic inverter assembly involved in this application allows for various relative position adjustments of the photovoltaic inverter 10 relative to load-bearing structures such as walls and brackets by adjusting the position of the adjustment plate assembly 40 in the height direction X of the photovoltaic inverter. Both the first mounting lug 201 and the second mounting lug 202 are detachably mounted on the adjustment plate assembly 40, and the position of the photovoltaic inverter 10 relative to the column 30 can be finely adjusted using the fine-tuning bolt 61 and fine-tuning nut. Therefore, it is possible to change the fixed position of the inverter even when the column 30 is already fixed relative to the photovoltaic inverter 10, thus improving the problem of mismatch between the actual cable connection position and the reserved connection position of the photovoltaic inverter 10.
[0043] It is understandable that the number of adjustment plate assemblies 40 is not limited to that shown. Figure 4 The number shown is 1, but it can be adjusted to more than two according to actual usage needs; the number of threaded fasteners 50 is not limited to this. Figure 4 The four shown could also be other numbers besides four; the mount 20 could also be hooked to one end of the adjustment plate 41 corresponding to the first notch 301 by the first hook 201.

The output terminal of the photovoltaic array is electrically connected to the DC terminal of the photovoltaic inverter component via a cable. The specific structure of the inverter component is the same as described in the above embodiment. Since the photovoltaic array system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
