Description

Technical Field

[0001] The present disclosure relates to the technical field of photovoltaic power generation, and in particular to a photovoltaic module system. Background Art

[0002] With the development of photovoltaic power generation technology, photovoltaic modules, as one of the important components of photovoltaic power stations, cannot directly output direct current for household electricity consumption. In order to achieve the conversion between direct current and alternating current, an inverter is required.

[0003] The existing technology currently uses a micro inverter for each photovoltaic module. The micro inverter is equipped with an inverter module with AC-DC conversion function and maximum power point tracking function for each photovoltaic module. The micro inverter is set up outdoors together with the photovoltaic module and is connected to each photovoltaic module respectively. The relationship between each photovoltaic module is parallel, and the electric energy generated by the photovoltaic module is directly converted into AC electric energy for use by AC loads or transmitted to the power grid. When one of the solar panels does not work well, only this one will be affected. The other photovoltaic modules will operate in the best working state, making the overall efficiency of the system higher and the power generation greater. Effectively reducing the loss of electric energy.

[0004] The installation scenarios of photovoltaic modules are complex, such as inclined installation on cement flat roofs, color steel tile roofs, tile inclined roofs and open ground. Micro inverters are packaged separately from photovoltaic modules and transported to the installation site, which has high transportation costs. In addition, the existing micro inverters are installed on the frame of photovoltaic modules, and the on-site installation location is complex, which makes the installation time-consuming and labor-intensive. Utility Model Content

[0005] Based on this, it is necessary to provide a photovoltaic module system.

[0006] The disclosed embodiment provides a photovoltaic module system, which includes a photovoltaic module, a micro inverter and a fixing assembly. The photovoltaic module includes a back plate with a mounting position. A heat dissipation groove is provided on the outer wall of the micro inverter. The fixing assembly is used to set the micro inverter on the photovoltaic module. The fixing assembly includes a support member, a limit member and a fastener. Among them, the support member is fixed at the mounting position. The support member includes a base plate, a limit part and a limit frame, the limit part and the limit frame are both provided on the base plate and are surrounded by the base plate to form a space for accommodating the micro inverter, the side of the base plate away from the limit part is fixed to the mounting position, the limit member passes through the limit frame and is engaged with the heat dissipation groove, and the fastener fixes the limit frame to the limit member.

[0007] In the photovoltaic module system provided by the embodiment of the present disclosure, the support member is fixed on the back plate of the photovoltaic module, the space formed by the support member is used to accommodate the micro inverter, the limit member is engaged with the micro inverter for limiting, and the micro inverter is fixed on the support member with the cooperation of the fastener. The installation of the micro inverter by fixing the component is simple and efficient. The installed photovoltaic module system is simple and convenient to install in complex scenes. The installed photovoltaic module system can be packaged and transported together, which reduces the transportation cost.

[0008] In some embodiments, the limiting member includes a fixing portion and a clamping portion connected to the fixing portion, the clamping portion is clamped with the heat dissipation groove, and the fixing portion is fixed to the limiting frame by a fastener.

[0009] With such arrangement, the limiting member has a simple structure and is easy to operate. It is placed in the limiting frame to limit the micro inverter and is convenient for fixing the micro inverter with the fastener.

[0011] With such arrangement, the clamping structure between the convex strip and the heat dissipation groove is simple and relatively firm, which is convenient for limiting the micro inverter along the thickness direction and for the limiter to move and fix together with the micro inverter.

[0012] In some embodiments, the limit frame is a hollow structure, and the bottom of the limit frame is fixed to the bottom plate, the top of the limit frame is provided with a limit hole, the bottom of the limit frame is provided with a threaded hole, the fixing part passes through the limit frame, the fixing part is provided with a threaded hole, and the fastener is provided with an external thread that cooperates with the threaded hole.

[0013] With this arrangement, the threaded connection facilitates the installation and removal of the fasteners, the fixings and the limiters, and the operation is simple and can quickly switch the position of the micro inverter along the thickness direction. At the same time, the threaded connection has a simple structure, is reliable and not easy to loosen, and is easy to transport and install the entire photovoltaic module after being fixed.

[0014] In some embodiments, the fixing portion is movably disposed in the limiting frame along a direction from the top to the bottom of the limiting frame.

[0015] With such a configuration, the change in the position of the fixing portion can drive the micro inverter to change its position from the top to the bottom of the limiting frame, so that the distance between the micro inverter and the bottom plate changes, thereby providing a variety of usage states, which is beneficial to the transportation, installation and use of the micro inverter. When the fixing portion is close to the top of the limiting frame, the micro inverter and the bottom plate form sufficient heat dissipation space, which is beneficial to the natural heat dissipation of the micro inverter and reduces the high temperature baking of the photovoltaic module.

[0017] With such arrangement, the limit member and the limit frame can be pre-fixed or re-fixed through the engagement of the buckle with the slot, thereby improving the accuracy, reliability and firmness of the fixation of the micro inverter.

[0018] In some embodiments, the bottom plate is square; there are at least two limiting portions, and at least two limiting portions are located at opposite corners of the bottom plate; there is at least one limiting frame, and the limiting frame avoids the limiting portions.

The micro inverter is placed in the support member and is not higher than the top of the support frame, and the support member and the micro inverter are fixed to the back plate and are not higher than the outer surface of the frame, so that the micro inverter can be packaged and transported together with the photovoltaic module, saving transportation space and reducing transportation costs.

[0022] In some of these embodiments, the support member is a one-piece structure.

[0023] With such arrangement, the support member can be formed into an integrated structure by injection molding, thereby achieving precise control of the size.

[0024] In some of the embodiments, the support member further includes an adhesive layer, which is disposed on a side of the bottom plate away from the limiting portion and is used for gluing to the installation position.

[0025] The back adhesive layer facilitates the bonding and curing of the support member during the photovoltaic production process, so that the support member is not easy to fall off the back plate. BRIEF DESCRIPTION OF THE DRAWINGS

The side of the base plate 311 away from the limit portion 312 is fixed to the installation position. The limit portion 312, the limit frame 313 and the base plate 311 are surrounded to form a space. The space is used to accommodate the micro inverter 2. The limit member 32 passes through the limit frame 313 and is clamped with the heat dissipation groove 21. The fastener 33 fixes the limit frame 313 to the limit member 32.

[0045] refer to Figures 1 to 3 In the photovoltaic module system 100 provided in the embodiment of the present disclosure, the side of the bottom plate 311 facing away from the limiting portion 312 and the limiting frame 313 is fixed to the back plate 11 of the photovoltaic module 1. The micro inverter 2 is placed in the space formed by the limiting portion 312, the limiting frame 313 and the bottom plate 311 in the direction toward the bottom plate 311 for limiting in four directions, and the outer wall of the micro inverter 2 faces the limiting portion 312 and the limiting frame 313. The limiting member 32 is placed in the limiting frame 313 so that the limiting frame 313 partially penetrates and engages with the heat dissipation groove 21, and the limiting member 32 limits the displacement of the micro inverter 2 in the placement direction. The fixing member fixes the limiting member 32 on the limiting frame 313 so that the micro inverter 2 is fixed on the support member 31. At this time, the micro inverter is arranged on the back plate 11 of the photovoltaic module 1 through the fixing member 3 to form the photovoltaic module system 100.

[0046] In the photovoltaic module system 100 provided in the embodiment of the present disclosure, the support member 31 is fixed to the back plate 11, the support member 31 and the stopper 32 limit the freedom of the micro inverter 2 in all directions, and the fastener 33 fixes the position of the stopper 32 and the micro inverter 2. The installation of the micro inverter 2 by the fixing component 3 is simple and efficient, and the photovoltaic module system 100 after installation is simple and convenient when installed in a complex scene. The photovoltaic module system 100 after installation can be packaged and transported together, reducing the transportation cost.

[0047] Exemplarily, the back plate 11 has multiple mounting positions. Exemplarily, the back plate 11 is mounted in the middle position. Exemplarily, the back plate 11 is mounted near the frame 12.

[0048] Exemplarily, the micro inverter 2 has outer walls in the up, down, left and right directions. Exemplarily, heat dissipation grooves 21 are provided on the upper outer wall, the left outer wall and the right outer wall of the micro inverter 2. Exemplarily, there are four heat dissipation grooves 21 on each outer wall.

[0049] Exemplarily, the rear side of the bottom plate 311 of the support member 31 is fixed to the installation position of the back plate 11. Exemplarily, the limiting portion 312 and the limiting frame 313 are located at the front side of the bottom plate 311.

[0050] Exemplarily, the space for accommodating the micro inverter 2 formed by the limiting portion 312 and the limiting frame 313 limits the micro inverter 2 in the up, down, left, and right directions.

[0051] By way of example, the fastener 33 may be a screw, a bolt, a rivet, or the like.

[0052] refer to Figure 3 In some embodiments, the bottom plate 311 is in a square shape. There are at least two limiting portions 312 , and at least two limiting portions 312 are located at opposite corners of the bottom plate 311 . There is at least one limiting frame 313 , and the limiting frame 313 avoids the limiting portions 312 .

[0053] In this way, after placing the micro-inverter 2, the space formed by at least two limiting parts 312 at the corners opposite to the bottom plate 311 and the bottom plate 311 is convenient for limiting the outer wall direction of the micro-inverter 2, and the limiting parts 312 at the corners can reduce the influence on the natural heat dissipation of the micro-inverter 2. The limiting frame 313 avoids the limiting part 312 to facilitate the installation and removal of the limiting member 32, and at the same time limits the displacement of the micro-inverter 2 in the thickness direction, so that the installation of the micro-inverter 2 is simple and convenient.

[0054] Exemplarily, the bottom plate 311 is square, the limiting parts 312 have two positions connected to two opposite corners of the bottom plate 311, and there is one position limiting frame 313. Exemplarily, in some embodiments, the two limiting parts 312 are respectively located at the upper left corner and the lower right corner of the bottom plate 311, and the two limiting parts 312 are arranged in opposite directions, and the limiting frame 313 can be connected to any one of the upper, lower, left and right sides of the bottom plate 311, or the limiting frame 313 can be connected to the lower left corner or the upper right corner.

It can be understood that the limiting parts 312 located at the two bottom corners bear the gravity of the micro inverter 2.

[0056] Exemplarily, the bottom plate 311 is square, the limiting parts 312 are four and respectively located at the four corners of the bottom plate 311, and the limiting frames 313 are two and respectively connected to two opposite sides of the bottom plate 311. In other embodiments, the two limiting frames 313 can also be connected to two adjacent sides of the bottom plate 311.

[0057] Exemplarily, the limiting portion 312 is tilted and arranged at a corner. In other embodiments, the limiting portion 312 can also be arranged at a corner in a right angle, a fan shape or other shapes.

[0058] Exemplarily, the limiting portion 312 connected to the two lower corners is provided with a protrusion 3121, and the protrusion 3121 faces upward and can limit the micro inverter 2 from the upper and lower directions.

[0059] Exemplarily, when the bottom plate 311 is square, the limiting frames 313 are connected to two opposite sides of the bottom plate 311 , and the limiting members 32 penetrate the limiting frames 313 along opposite directions.

[0060] In other embodiments, the limit frame 313 can also be connected to the corner of the bottom plate 311, and the limit member 32 can pass through the limit frame 313 in the up-down direction or in the left-right direction, or the limit member 32 can pass through the limit frame 313 in both the up-down direction and the left-right direction at the same time.

[0061] refer to Figure 2 In some embodiments, the limiting member 32 includes a fixing portion 321 and a clamping portion 322 connected to the fixing portion 321. The clamping portion 322 is clamped with the heat dissipation groove 21. The fixing portion 321 is fixed to the limiting frame 313 by a fastener 33.

[0062] With such arrangement, the limiting member 32 has a simple structure and is easy to operate. It is placed in the limiting frame 313 to limit the micro inverter 2 and is convenient to cooperate with the fastener 33 to fix the micro inverter 2 .

[0063] Exemplarily, the clamping portion 322 and the fixing portion 321 are perpendicular to and connected to each other. After the limiting member 32 enters the limiting frame 313, the clamping portion 322 passes through the limiting frame 313 and enters the space to clamp with the heat dissipation groove 21. The fixing portion 321 is located in the limiting frame 313, and the fastener 33 fixes the fixing portion 321 to the limiting frame 313 along the front-to-back direction.

[0064] refer to Figure 3 and Figure 4 In some embodiments, there are multiple heat dissipation grooves 21, which are arranged at intervals along the thickness direction of the micro inverter 2, and the clamping portion 322 is provided with at least one convex strip 3221 that cooperates with the heat dissipation groove 21, and the convex strip 3221 is clamped in the heat dissipation groove 21.

[0065] With such arrangement, the clamping structure between the protruding strip 3221 and the heat dissipation groove 21 is simple and relatively firm, which is convenient for limiting the micro inverter 2 along the thickness direction and for the limiting member 32 to move and fix together with the micro inverter 2 .

[0066] Exemplarily, the convex strips 3221 are arranged at intervals along the thickness direction of the micro inverter 2 , and the shape of the convex strips 3221 matches the shape of the heat dissipation grooves 21 .

[0067] Exemplarily, the heat dissipation groove 21 is in the shape of a cuboid, and the convex strip 3221 is also in the shape of a cuboid.

[0068] Exemplarily, there are three heat dissipation grooves 21 , and the clamping portion 322 is provided with a convex strip 3221 . One convex strip 3221 can be clamped to any heat dissipation groove 21 .

[0069] Exemplarily, there are three heat dissipation grooves 21, and the clamping portion 322 is provided with three convex strips 3221. The three convex strips 3221 are clamped with the three heat dissipation grooves 21 one by one, so that the connection between the limiter 32 and the micro inverter 2 is more firm, the installation accuracy is higher, and it is more convenient for both to move and fix at the same time.

[0070] Exemplarily, the heat dissipation groove 21 faces the right side, and the protruding strip 3221 faces the left side, and the fixing portion 321 is located on the right side of the clamping portion 322 .

[0071] refer to Figure 2 and Figure 3In some embodiments, the limit frame 313 is a hollow structure, and the bottom of the limit frame 313 is fixed to the bottom plate 311, the top of the limit frame 313 is provided with a limit hole 35, the bottom of the limit frame is provided with a threaded hole 34, the fixing portion 321 passes through the limit frame 313, the fixing portion 321 is provided with a threaded hole 34, and the fastener 33 is provided with an external thread that matches the threaded hole 34.

[0072] In this way, the threaded connection facilitates the installation and removal between the fastener 33 and the fixing member and the stopper 32, and the operation is simple and can quickly switch the position of the micro inverter 2 along the thickness direction. At the same time, the threaded connection has a simple structure, the connection is reliable and not easy to loosen, and after being fixed, it is convenient for the transportation and installation of the entire photovoltaic assembly 1.

[0073] Exemplarily, the limit member 32 enters the hollow structure so that the limit hole 35 at the top of the limit frame 313, the threaded hole 34 of the fixing part 321 and the threaded hole 34 at the bottom of the limit frame 313 are arranged side by side in the front-to-back direction, and the fastener 33 passes through the limit hole 35 and the two threaded holes 34 in sequence from front to back so that the external thread and the internal thread cooperate to fix the fixing part 321 to a specific position of the limit frame 313.

[0074] Exemplarily, the threaded hole 34 at the bottom of the limiting frame 313 and the threaded hole 34 of the fixing portion 321 are both formed by nuts. The nuts are implanted into the bottom of the limiting frame 313 and the fixing portion 321 by in-mold injection molding or hot melting.

[0075] refer to Figure 4 In some embodiments, the thickness of the micro inverter 2 is less than or equal to 25 mm. The thickness of the micro inverter 2 is less than the thickness of the support member 31. The photovoltaic module 1 also includes a frame 12, and the micro inverter 2 and the support member 31 do not protrude from the outer surface of the frame 12 along the thickness direction.

[0076] With such arrangement, the thickness of the micro inverter 2 is small. The micro inverter 2 is placed in the support member 31 and is not higher than the top of the support frame, and the support member 31 and the micro inverter 2 are not higher than the outer surface of the frame 12 when fixed to the back plate 11, so that the micro inverter 2 can be packaged and transported together with the photovoltaic module 1, saving transportation space and reducing transportation costs.

[0077] Exemplarily, the bottom plate 311 is closely attached to the back plate 11, and the micro inverter 2 is placed in the space formed by the support member 31. The clamping portion 322 of the limit member 32 passes through the limit frame 313, so that the fixing portion 321 abuts against the bottom of the limit frame 313, and the convex strip 3221 is clamped with the heat dissipation groove 21. The fastener 33 is inserted into the threaded hole 34 at the top of the limit frame 313, the fixing portion 321, and the bottom of the limit frame 313 in sequence, so that the outer surface of the fastener 33 is flush with the outer surface of the top of the limit frame 313. At this time, the freedom of the micro inverter 2 in all directions is limited by the limit member 32 and the support member 31, and the outer surface of the micro inverter 2 is flush with the outer surface of the fixing component 3, and the outer surface of the fixing component 3 is not higher than the outer surface of the frame 12. At this time, the micro inverter 2 is in the transportation state after installation. The installed micro inverter 2 is packaged and transported together with the photovoltaic component 1.

[0078] refer to Figure 5 and Figure 6 In some embodiments, the fixing portion 321 is movably disposed in the limiting frame 313 along a direction from the top to the bottom of the limiting frame 313 .

[0079] With such arrangement, the position change of the fixing portion 321 can drive the micro inverter 2 to change its position from the top to the bottom of the limiting frame 313, so that the distance between the micro inverter 2 and the bottom plate 311 changes, thereby providing a variety of use states, which is beneficial to the transportation, installation and use of the micro inverter 2. When the fixing portion 321 is close to the top of the limiting frame 313, the micro inverter 2 and the bottom plate 311 form sufficient heat dissipation space, which is beneficial to the natural heat dissipation of the micro inverter 2 and the reduction of high temperature baking of the photovoltaic module 1.

[0080] Exemplarily, the direction from the top to the bottom of the limiting frame 313 is the front-to-back direction. The fixing portion 321 can move from front to back or from back to front in the hollow structure of the limiting frame 313 .

[0081] Exemplarily, when the fastener 33 is loose or not installed and the protrusion 3221 is engaged with the heat dissipation groove 21, the fixing portion 321 moves forward from a position close to the bottom of the limit frame 313 to a position close to the top of the limit frame 313, and the micro inverter 2 moves forward together with the limit member 32 so that the outer surface of the micro inverter 2 is higher than the outer surface of the support member 31 and the outer surface of the frame 12. There is a certain distance between the micro inverter 2 and the base plate 311. The fastener 33 is inserted into the threaded hole 34 at the top of the limit frame 313, the fixing portion 321, and the bottom of the limit frame 313 in sequence and fixed, so that the working state of the micro inverter 2 is locked.

[0082] Exemplarily, when the micro inverter 2 is working, the distance between the micro inverter 2 and the bottom plate 311 is greater than 13 mm, so that the micro inverter 2 can achieve a better heat dissipation effect.

[0083] refer to Figure 2 and Figure 5 In some embodiments, the limiting member 32 further includes one of a buckle 323 or a slot 3131 disposed on the fixing portion 321 , and the other is disposed on the top of the limiting frame 313 , and the buckle 323 is engaged with the slot 3131 .

[0084] With such arrangement, the stopper 323 and the stopper frame 313 can be pre-fixed or re-fixed by the engagement of the stopper 323 with the slot 3131 , thereby improving the accuracy, reliability and firmness of the fixation of the micro inverter 2 .

[0085] Exemplarily, the fixing portion 321 is provided with a buckle 323 , and a slot 3131 is provided at the top of the limiting frame 313 .

[0086] In other embodiments, a slot 3131 is provided on the fixing portion 321 , and a buckle 323 is provided on the top of the limiting frame 313 .

[0087] Exemplarily, there are multiple buckles 323 and multiple slots 3131 , and one buckle 323 corresponds to one slot 3131 .

[0088] Exemplarily, there are two locking slots 3131 , which are respectively disposed on both sides of the limiting hole 35 at the top of the limiting frame 313 .

[0089] refer to Figure 1 , Figure 4 and Figure 7 , exemplarily, when the fastener 33 is a screw, the tool is a screwdriver. The step of switching the micro inverter 2 from the installation state to the working state is: use a screwdriver to tighten the screw. When the screw leaves the bottom of the limit frame 313, the screw can be stopped. At this time, the screw and the limit member 32 form a whole. Because the limit member 32 is engaged with the micro inverter 2, the limit member 32 can only move with the micro inverter 2. When the micro inverter 2 is pulled forward, the limit member 32 will also move forward. When the buckle 323 is engaged in the slot 3131, the micro inverter 2 can achieve a temporary fixation effect. Then, the screw is tightened into the threaded hole 34 at the bottom of the limit frame 313, and finally the working state locking of the micro inverter 2 and the photovoltaic module 1 is completed, and the micro inverter 2 is switched from the installation state to the working state. The photovoltaic module system 100 can realize the state switching of the micro inverter 2 by using a screwdriver. The limiter 32 and the micro inverter 2 maintain a single-direction degree of freedom, and at the same time combine the two fixing methods of the buckle 323 and the screw, so that the installation of the micro inverter 2 is simple and efficient, and the state switching is convenient and fast.

[0090] refer to Figure 1 and Figure 3In some embodiments, the micro inverter 2 further includes a hook 22, an output terminal 23, an input terminal 24 and an antenna 25 disposed on the outer wall. The outer wall of the micro inverter 2 is made of aluminum alloy, and the bottom plate 311 is provided with an opening 3111.

[0091] Such a configuration facilitates the input, output and conversion of current by the micro inverter 2. Metal transfers heat quickly and has strong heat dissipation capacity. The opening 3111 increases the heat dissipation space, which is beneficial to the natural heat dissipation of the micro inverter 2 and reduces the high temperature baking of the photovoltaic module 1.

[0092] Exemplarily, the hook 22 is disposed on the outer side wall of the upper portion of the micro inverter 2 , and the hook 22 is suitable for installation in a hole position of an aluminum profile or a steel profile.

[0093] Exemplarily, the output terminal 23 , the input terminal 24 and the antenna 25 are disposed on the outer side wall of the lower portion of the micro inverter 2 , and the outer side wall of the lower portion is not provided with a heat dissipation groove 21 .

[0094] Exemplarily, an opening 3111 is provided in the middle of the bottom plate 311. Exemplarily, an opening 3111 is provided near an edge of the bottom plate 311.

[0095] Exemplarily, the number of the openings 3111 may be one or more.

[0096] Exemplarily, the shape of the opening 3111 is square, circular, or polygonal.

[0097] In other embodiments, the bottom plate 311 may be a completely flat surface.

[0098] In some of the embodiments, the support member 31 is an integral structure.

[0099] Exemplarily, the support member 31 is made of plastic material.

[0100] With such arrangement, the support member 31 can be formed into an integrated structure by injection molding, thereby achieving precise control of the size.

[0101] In some embodiments, the support member 31 further includes an adhesive layer (not shown), which is disposed on a side of the bottom plate 311 away from the limiting portion 312 , and is used for gluing to the installation position.

[0102] The adhesive layer facilitates the bonding and curing of the support member 31 during the photovoltaic production process, so that the support member 31 is not easy to fall off the back plate 11.

[0103] It is understandable that the bottom plate 311 and the mounting position may also be connected in other ways.

[0104] The technical features of the embodiments disclosed above can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the embodiments described above are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0105] The above disclosed embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
