Description

Technical Field

[0001] This invention relates to the field of photovoltaic module technology, specifically to an optimizer and its control system for photovoltaic modules. Background Technology

[0002] The output current and power of photovoltaic (PV) modules are closely related to their operating environment (especially sunlight). Since the operating current of modules connected in series in the same string must be consistent, the operating point of a module affected by mismatch will shift as the current decreases, resulting in a reduction in the output power of the entire string. This is known as the "weakest link" effect in PV power generation. To solve this problem, a PV optimizer is usually installed on each PV module. This optimizer uses a DC-DC circuit to perform power conversion, ultimately achieving higher power generation and intelligent management at the module level. During use, when a PV module experiences power mismatch, the PV optimizer uses its internal small transformer DC-DC control circuit to change the module's output current to match the current of other modules. Of course, the PV optimizer needs to monitor the output current of other modules in the same string, and only after detecting inconsistencies can it adjust its own output current.

[0003] However, existing photovoltaic optimizers are usually installed on the back of the photovoltaic panels using combination bolts. The combination bolts and mounting ears make the installation and fixing of photovoltaic optimizers relatively simple. However, when used in some windy and complex environments, the photovoltaic modules will vibrate under the action of wind. The vibration often affects the stability and firmness of the photovoltaic optimizer installation. In addition, the photovoltaic optimizer itself lacks a protective mechanism, which cannot effectively guarantee its safety during use. Summary of the Invention

[0004] The purpose of this invention is to provide an optimizer and its control system for photovoltaic modules, so as to solve the problems mentioned in the background art where the optimizer is not securely installed under harsh environmental conditions and lacks a protective mechanism.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An optimizer for photovoltaic modules includes: a housing, on which a sealing plate is fixedly mounted, and a hanging ear is inserted between the housing and the sealing plate, the hanging ear protruding from the outside of the housing; A multi-point fixing assembly is installed on the housing and the mounting ears. The optimizer is installed on the photovoltaic panel through the multi-point fixing assembly to ensure its installation is firm. An optimizer protection component is movably connected to a multi-point fixing component, and the multi-point fixing component moves the optimizer to protect it. A locking assembly, which is mounted on the housing to lock the multi-point fixing assembly.

[0006] Preferably, the multi-point fixing component includes: a load-bearing drive bar, which is mounted on the hanging ear; Two movable support plates are installed on both sides of the outer casing, respectively. The first connecting strip is used to connect the drive strip and the movable support plate.

[0007] Preferably, the load-bearing drive bar cooperates with the hanging ear to fix the optimizer in the first auxiliary layer.

[0008] Preferably, when the load-bearing drive bar moves, it drives the movable load-bearing plate to move, and the movable load-bearing plate provides a second layer of auxiliary fixation for the optimizer.

[0009] Preferably, when the movable support plate fixes the optimizer, it is in a separated state from the outer shell.

[0010] Preferably, the optimizer protection assembly includes: a first protective plate, which is mounted on a movable support plate on one side of the housing; The second protective plate is mounted on the movable support plate on the other side of the outer shell.

[0011] Preferably, when the optimizer is installed on the photovoltaic panel, the first protective plate protects it, and the first protective plate is separated from the outer casing.

[0012] Preferably, when the optimizer is installed on the photovoltaic panel, it is protected by a second protective plate, and the second protective plate is separated from the outer casing.

[0013] Preferably, the locking assembly includes: a connecting frame, which is movably connected to a movable support plate, and the movable support plate drives the frame to move. There are two connecting frames, one of which is movably connected to the first protective plate and the other is movably connected to the second protective plate; A locking baffle is used to lock the load-bearing drive bar.

[0014] A control system for an optimizer for photovoltaic modules includes a central controller module, a transmission module, a monitoring module, and an adjustment module. The monitoring module on each photovoltaic module monitors the output current of other photovoltaic modules in the same string. When it detects an inconsistency in the output current, it transmits the monitoring information to the central processor module through the transmission module. The central processor module then issues instructions to the adjustment module through the transmission module, and the adjustment module adjusts the output current.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages: 1. By fixing the device at multiple points, the stability of the optimizer installation can be enhanced, ensuring that it will not loosen during use.

[0016] 2. While protecting the optimizer, it also provides ample space for heat dissipation, ensuring its safety during use. At the same time, it can lock the bolts to prevent rotation during long-term use, effectively ensuring the stable installation of the optimizer. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This invention provides a technical solution: like Figure 1 As shown, an optimizer for photovoltaic modules includes: a housing 1, a multi-point fixing component, an optimizer protection component, and a locking component. A sealing plate 2 is fixedly mounted on the housing 1 with screws, and a hanging ear 3 is inserted between the housing 1 and the sealing plate 2. The hanging ear 3 protrudes from the outside of the housing 1. The multi-point fixing component is installed on the housing 1 and the hanging ear 3, and the optimizer is installed on the photovoltaic panel 9 through the multi-point fixing component. The multi-point fixing of the optimizer ensures its installation firmness. The optimizer protection component is movably connected to the multi-point fixing component, and the multi-point fixing component moves the optimizer to protect it from damage caused by external forces during use, ensuring its safety. The locking component is installed on the housing 1 to lock the multi-point fixing component. When the multi-point fixing component is locked, it cannot move in the opposite direction, thereby ensuring the stability and reliability of the optimizer installation.

[0032] like Figure 2 and Figure 3 As shown, when installing the hanging ear 3, one end face of the hanging ear 3 is brought into contact with the outer shell 1, and then the sealing plate 2 is placed over the port of the outer shell 1 so that the sealing plate 2 is in contact with the other end face of the hanging ear 3. In this way, the hanging ear 3 can be clamped by the outer shell 1 and the sealing plate 2. In order to ensure the firmness of the installation of the hanging ear 3, a support protrusion 21 is integrally formed on the upper end of the sealing plate 2, and a support channel 31 is opened at the lower end of the hanging ear 3. The support protrusion 21 is inserted into the support channel 31 so that the hanging ear 3 can be stably installed between the outer shell 1 and the sealing plate 2, and the support protrusion 21 is in contact with the inner wall of the support channel 31, and the hanging ear 3 is supported by the support protrusion 21.

[0033] like Figure 1 and Figure 2 As shown, the multi-point fixing assembly includes: a load-bearing drive bar 4, a movable load-bearing plate 5, and a first connecting bar 45. The load-bearing drive bar 4 is installed on the lug 3 and can move relative to the lug 3. Specifically, symmetrical guide holes 32 are provided on the lug 3, and load-bearing protrusions 42 are integrally formed symmetrically on the load-bearing drive bar 4. A guide support rod 43 is integrally formed on the load-bearing protrusion 42. The guide support rod 43 is inserted into the guide hole 32. The load-bearing drive bar 4 is supported by the cooperation between the guide support rod 43 and the guide hole 32. In addition, a through hole 41 is provided on the load-bearing drive bar 4.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, there are two movable support plates 5, which are respectively installed on both sides of the outer shell 1. In order to install the movable support plates 5, a lower protruding support platform 11 is integrally formed at the lower end of the outer shell 1. The lower protruding support platform 11 has symmetrical movable support insertion holes 12 on both sides. On the upper end of the outer shell 1, upper protruding support plates 13 are also integrally formed symmetrically on both sides. Support guide holes 14 are opened on the upper protruding support plates 13. A first mating support rod 51 is welded and fixed to the upper end of the movable support plate 5. The first mating support rod 51 is inserted into the... In the support guide hole 14, the support guide hole 14 and the first mating support rod 51 cooperate to support the movable support plate 5 from the upper end. The lower end of the movable support plate 5 is symmetrically and integrally formed with a support protrusion 55. The support protrusion 55 is welded and fixed to the support protrusion 55. The second mating support rod 56 is inserted into the movable support insertion hole 12. The second mating support rod 56 cooperates with the movable support insertion hole 12 to support the movable support plate 5 from the lower end.

[0035] The first connecting strip 45 is used to connect the drive strip 4 and the movable support plate 5. Specifically, two lower extension frames 44 are symmetrically and integrally formed at the lower end of the drive strip 4. One end of the first connecting strip 45 is hinged to the lower extension frame 44, and the other end of the first connecting strip 45 is hinged to the movable support plate 5. That is, a connecting strip frame 52 is welded and fixed on the first mating support rod 51 on the movable support plate 5. The connecting strip frame 52 is hinged to the first connecting strip 45. In addition, a connecting spring 511 is sleeved on the first mating support rod 51. The connecting spring 511 is located between the connecting strip frame 52 and the upper convex support plate 13, and the two ends of the connecting spring 511 are in contact with the connecting strip frame 52 and the upper convex support plate 13, respectively. When the movable support plate 5 moves away from the outer shell 1, the connecting spring 511 is in a compressed state, that is, the connecting spring 511 is used for the reset of the movable support plate 5.

[0036] like Figure 10 and Figure 11 As shown, a mounting groove 91 is provided on the back of the photovoltaic panel 9. When installing the optimizer, the casing plate 2 is inserted into the mounting groove 91. The mounting position of the optimizer is positioned by the cooperation between the casing plate 2 and the mounting groove 91. At this time, the hanging ear 3 is in contact with the photovoltaic panel 9. A threaded hole 92 is provided on the photovoltaic panel 9 on the upper side of the mounting groove 91. Load bearing holes 93 are provided on both sides of the threaded hole 92. When fixing the optimizer, the bolt is inserted into the threaded hole 92 through the mating through hole 41 on the load-bearing drive bar 4. Then, the bolt is rotated to move it under the action of the thread. As the bolt moves, its head contacts the load-bearing drive bar 4, which in turn pushes the load-bearing drive bar 4 towards the lug 3. This causes the guide support rod 43 to be inserted into the load-bearing hole 93 until the load-bearing protrusion 42 contacts the lug 3. In this way, the bolt can fix the lug 3 through the load-bearing drive bar 4. Since the guide support rod 43 is inserted into the load-bearing hole 93 at this time, the cooperation between the guide support rod 43 and the load-bearing hole 93 can strengthen the fixation of the optimizer. Thus, the cooperation between the load-bearing drive bar 4 and the lug 3 can provide the first layer of auxiliary fixation for the optimizer.

[0037] When the load-bearing drive bar 4 moves, it drives the movable load-bearing plate 5 to move as well. Specifically, when the load-bearing drive bar 4 moves towards the hanging ear 3, the first connecting bar 45 drives the two movable load-bearing plates 5 to move in opposite directions, and both move away from the outer shell 1. To achieve a second layer of auxiliary fixation for the optimizer through the movable load-bearing plates 5, load-bearing mounting plates 94 are symmetrically welded and fixed on both sides of the mounting groove 91. Load-bearing insertion channels 95 are opened on the load-bearing mounting plates 94, and a support is integrally formed on the movable load-bearing plate 5. When the optimizer is positioned on the photovoltaic panel 9 via the mounting groove 91, the support block 53 is aligned with the bearing insertion channel 95 on the bearing mounting plate 94. When the bearing drive bar 4 moves the movable bearing plate 5 away from the outer shell 1 via the first connecting bar 45, the support block 53 can be inserted into the bearing insertion channel 95. In this way, the support block 53 and the bearing insertion channel 95 cooperate to provide a second layer of auxiliary fixation for the optimizer. Under the action of double auxiliary fixation, the stability of the optimizer installation can be fully guaranteed.

[0038] When the movable support plate 5 is used to fix the optimizer, it is separated from the outer casing 1. When the movable support plate 5 is used to assist in fixing the optimizer, it means that the optimizer is installed on the photovoltaic panel 9 and is in working condition. When the optimizer is in working condition, it will generate a lot of heat. The separation of the movable support plate 5 from the outer casing 1 can avoid the movable support plate 5 from having an adverse effect on the heat dissipation of the optimizer. When the optimizer is not installed, the movable support plate 5 is in contact with the sides of the outer casing 1. This makes the overall size of the optimizer smaller, which is convenient for the optimizer to be encapsulated and stored.

[0039] like Figure 4 , Figure 6 and Figure 7 As shown, the optimizer protection assembly includes a first protective plate 6 and a second protective plate 7. The first protective plate 6 is mounted on a movable support plate 5 on one side of the outer shell 1, and the second protective plate 7 is mounted on a movable support plate 5 on the other side of the outer shell 1. Specifically, a movable insertion cavity 54 is provided on the movable support plate 5. The inner wall of the movable insertion cavity 54 is smooth and burr-free. A first connecting plate 62 is integrally formed on the first protective plate 6. The surface of the first connecting plate 62 is smooth and burr-free. The first connecting plate 62 is inserted into the movable insertion cavity 54 on the movable support plate 5 on one side of the outer shell 1. A second connecting plate 72 is integrally formed on the second protective plate 7. The surface of the second connecting plate 72 is smooth and burr-free. The second connecting plate 72 is inserted into the movable insertion cavity 54 on the movable support plate 5 on the other side of the outer shell 1. When the movable support plate 5 moves, it can drive the first protective plate 6 and the second protective plate 7 to move synchronously.

[0040] When the optimizer is installed on the photovoltaic panel 9, it is protected by the first protective plate 6, which is separate from the outer casing 1. Similarly, when the optimizer is installed on the photovoltaic panel 9, it is protected by the second protective plate 7, which is also separate from the outer casing 1. This separation of the first and second protective plates provides ample space for heat dissipation, ensuring effective heat dissipation. Furthermore, a mating slot 63 is provided on the first protective plate 6, and the second protective plate 7 is integrally formed on it. Equipped with a mating insert 73, when the optimizer is not installed on the photovoltaic panel 9, the mating insert 73 on the second protective plate 7 is fully inserted into the mating slot 63 on the first protective plate 6, and at this time, both the first protective plate 6 and the second protective plate 7 are in contact with the outer casing 1, minimizing the overall size of the optimizer. When the first protective plate 6 and the second protective plate 7 move in opposite directions along with the movable support plate 5, the mating insert 73 partially moves out of the mating slot 63, thus opening the mating slot 63 and allowing for better heat dissipation of the optimizer. Figure 7 As shown.

[0041] like Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the locking assembly includes a connecting frame 8 and a locking baffle 86. The connecting frame 8 is movably connected to the movable bearing plate 5, and is moved by the movable bearing plate 5. There are two connecting frames 8, one movably connected to the first protective plate 6 and the other movably connected to the second protective plate 7. Specifically, a second connecting strip 83 is hinged to one end of the connecting frame 8 near the lug 3, and the other end of the second connecting strip 83 is hinged to the connecting strip plate 52 near it. Moving bearing holes 81 are symmetrically provided at both ends of the connecting frame 8. The connecting frame 8 is sleeved onto the support mounting rod 15 on the upper convex bearing plate 13 through the moving bearing holes 81. The movement of the connecting frame 8 is restricted by the support mounting rod 15, so that the connecting frame 8 can only move along the support mounting rod 15. A connecting fitting is integrally formed at the lower end of the connecting frame 8 away from the lug 3. The first protective plate 6 has a first connecting cavity 61 at its upper end, and the second protective plate 7 has a second connecting cavity 71 at its upper end. The connecting block 82 on the connecting frame 8 above the first protective plate 6 is inserted into the first connecting cavity 61 and contacts the inner wall of the first connecting cavity 61, thus realizing the movable connection between the connecting frame 8 and the first protective plate 6. The connecting block 82 on the connecting frame 8 above the second protective plate 7 is inserted into the second connecting cavity 71 and contacts the inner wall of the second connecting cavity 71, thus realizing the movable connection between the connecting frame 8 and the second protective plate 7. When the connecting frame 8 moves along the support rod 15, the connecting block 82 will also drive the first protective plate 6 and the second protective plate 7 to move along the movable insertion cavity 54, thereby realizing the contact and separation of the first protective plate 6 and the second protective plate 7 from the outer shell 1.

[0042] like Figure 1 , Figure 2 , Figure 8 and Figure 9As shown, the locking baffle 86 locks the load-bearing drive bar 4. Specifically, the upper end of the outer shell 1 has a lower insertion channel 16, and the lower end of the locking baffle 86 is welded and fixed with a lower insertion support rod 87. The lower insertion support rod 87 is inserted into the lower insertion channel 16. The locking baffle 86 is limited by the cooperation between the lower insertion support rod 87 and the lower insertion channel 16. Furthermore, a spring sheet 88 is welded and fixed to the lower end of the locking baffle 86. The lower end of the spring sheet 88 is welded and fixed to the outer shell 1. The movement of the locking baffle 86 is achieved by the spring sheet 88, connecting the connecting frame 8. An upper protruding support strip 84 is welded and fixed on the upper protruding support strip 84. A lower pressure limiting strip 85 is integrally formed on the upper protruding support strip 84. When the lower pressure limiting strip 85 presses on the locking baffle 86, the elastic piece 88 is in a compressed state. Thus, when the lower pressure limiting strip 85 separates from the locking baffle 86, the elastic piece 88 will push the locking baffle 86 to move away from the outer shell 1. This allows the locking baffle 86 to contact the head of the bolt and limit its movement, preventing the bolt from moving and thus locking the load-bearing drive strip 4.

[0043] like Figure 12 As shown, a control system for an optimizer for photovoltaic modules includes a central controller module, a transmission module, a monitoring module, and an adjustment module. The monitoring module on each photovoltaic module monitors the output current of other photovoltaic modules in the same string. When it detects that the output current is inconsistent, it transmits the monitoring information to the central processor module through the transmission module. The central processor module then issues instructions to the adjustment module through the transmission module, and the adjustment module adjusts the output current.

[0044] During the installation of the optimizer, the casing plate 2 is inserted into the mounting groove 91 to position the optimizer. Then, the bolt is rotated using a tool to move it into the threaded hole 92. During this movement, the bolt pushes the load-bearing drive bar 4 to move synchronously. As the load-bearing drive bar 4 moves, the guide support rod 43 on the load-bearing drive bar 4 is inserted into the load-bearing hole 93. In this way, the cooperation between the guide support rod 43 and the load-bearing hole 93 can provide the first layer of auxiliary fixation for the optimizer. At this time, the load-bearing protrusion 42 is in contact with the lug 3. Thus, the bolt can clamp and fix the lug 3 through the load-bearing drive bar 4, thereby fixing the optimizer. Furthermore, when the load-bearing drive bar 4 moves, it will push the two movable load-bearing plates 5 to move in opposite directions under the action of the first connecting bar 45, that is, to move away from the outer shell 1. As the movable load-bearing plates 5 move, under the action of the second connecting bar 83, the connecting frame 8 will move away from the hanging ear 3. In turn, under the action of the connecting frame 8, the first protective plate 6 and the second protective plate 7 can be moved away from the outer shell 1. In this way, the movable load-bearing plates 5, the first protective plate 6 and the second protective plate 7 can all be separated from the outer shell 1, which can leave sufficient space for the heat dissipation of the optimizer. At the same time, with the help of the insert bar 73 and the cooperation Slot 63 is not completely separated, which keeps the slot open to facilitate heat dissipation for the optimizer while providing good protection for the optimizer under the action of the first protective plate 6 and the second protective plate 7, preventing it from being impacted by external forces. In addition, when the movable support plate 5 moves away from the outer shell 1, the support column 53 on the movable support plate 5 will be inserted into the support insertion channel 95. In this way, the cooperation between the support column 53 and the support insertion channel 95 can provide a second layer of auxiliary fixation for the optimizer. Multi-point fixation ensures its installation firmness. Furthermore, as the connecting frame 8 moves, the downward pressure limit strip 85 will no longer be... Pressing the locking baffle 86 on the bolt releases its restraints. Under the action of the elastic plate 88, the locking baffle 86 moves away from the outer casing 1, bringing it into contact with the bolt head. This limits the bolt's movement, preventing it from moving in the opposite direction and ensuring the stability of the optimizer installation. When the optimizer needs to be disassembled, pushing the locking baffle 86 towards the outer casing 1 removes it from contact with the bolt head, allowing the bolt to be rotated and moved in the opposite direction. Under the action of the connecting spring 511, the load-bearing drive bar 4 moves in the opposite direction, unlocking the optimizer and allowing it to be quickly removed.
