[0002] The photovoltaic controller is the core equipment in a photovoltaic power generation system. It is used to control the charging of the photovoltaic modules to the battery and the discharging of the battery to the load. It has functions such as charge and discharge protection, overcurrent protection, and short circuit protection.

[0003] Traditional photovoltaic controllers are mostly fixed to the wall directly with expansion bolts. Installation and disassembly require at least two people to work together, one to hold the equipment and the other to tighten or loosen the screws. This increases labor costs during installation and maintenance. In addition, traditional photovoltaic controllers are mostly integrated structures. If one photovoltaic module is damaged, the entire unit must be disassembled and replaced or the whole unit must be sent back to the factory for repair. The maintenance workload is large and the maintenance time is long, which affects the normal and stable operation of the base station. Therefore, those skilled in the art have provided a modular photovoltaic controller that can be quickly disassembled and assembled to solve the problems mentioned in the background art.

[0006] A modular photovoltaic controller for quick assembly and disassembly includes a fixed frame. The front of the fixed frame has two connecting strips, each with two hooks attached to its back. The interior of the fixed frame has two sets of mounting holes, each with a fastening screw on its front. An integrated box is bolted to the front of the two connecting strips. A sealed door is hinged to the front of the integrated box, with a handle attached to its front. A housing is attached to the back of the sealed door, and a partition is connected to the interior of the housing. Multiple photovoltaic control modules are installed inside the housing. Each photovoltaic control module has a DC input socket and a DC output socket on its left side, a positioning hole on its right side, a positioning bolt on the left side of each positioning hole, a module handle on its left side, and a heat dissipation channel on its right side.

[0007] As a further improvement of this utility model: each of the DC input sockets includes an input positive terminal and an input negative terminal, and each of the DC output sockets includes a DC output positive terminal and an output negative terminal.

[0008] As a further improvement of this utility model: a support plate is connected to the back of the sealing door, and the upper surface of the support plate is connected to the bottom surface of the box.

[0020] Please see Figures 1-5 In this embodiment of the present invention, a modular photovoltaic controller for quick assembly and disassembly includes a fixed frame 1. The front of the fixed frame 1 has two connecting strips 2, and the back of each connecting strip 2 is connected to two hooks 3. The interior of the fixed frame 1 has two sets of mounting holes 4, and the front of each mounting hole 4 is provided with a fastening screw 5. An integrated box 6 is bolted to the front of the two connecting strips 2. A sealing door 7 is hinged to the front of the integrated box 6, and a door handle 8 is connected to the front of the sealing door 7. A box body 9 is connected to the back of the sealing door 7. A partition plate 10 is connected inside the box body 9. Multiple photovoltaic control modules 11 are installed inside the box body 9. Each photovoltaic control module 11 has a DC input socket 12 and a DC output socket 13 installed on its left side. Each photovoltaic control module 11 has a positioning hole 14 on its right side, and a positioning bolt 15 is provided on the left side of each positioning hole 14. Each photovoltaic control module 11 has a module handle 16 connected to its left side, and a heat dissipation channel 17 opened on its right side. Each DC input socket 12 includes an input positive terminal 1201 and an input negative terminal 1202, and each DC output socket 13 includes a DC output positive terminal 1301 and an output negative terminal 1302. By clearly setting the input positive terminal 1201, input negative terminal 1202, output positive terminal 1301, and output negative terminal 1302 in the DC input socket 12 and DC output socket 13 respectively, the positive and negative terminals are avoided during wiring, ensuring the accuracy and safety of the circuit connection and reducing the risk of equipment damage due to wiring errors. At the same time, the partition plate 10 can separate the internal space of the box 9, so that multiple photovoltaic control modules 11 can be arranged in an orderly manner, avoiding mutual interference between modules and improving space utilization.

[0021] The back of the sealed door 7 is connected to a support plate 18, the upper surface of which is connected to the bottom surface of the housing 9. Two operation indicator lights 19 are installed on the front of the sealed door 7, and a model nameplate 20 is connected to the front of the sealed door 7. The support plate 18 can support the housing 9, enhance the stability of the housing 9, and ensure that the photovoltaic control module 11 is firmly installed inside the housing 9. The operation indicator lights 19 can intuitively display the operating status of the equipment, making it convenient for operators to understand whether the equipment is working properly in a timely manner.

[0022] Two inspection lights 21 are installed on the inner top wall of the integrated box 6. The outer surface of the door handle 8 is covered with an insulating coating. A heat dissipation window 22 is opened on the right side of the integrated box 6. A dust filter screen is connected inside the heat dissipation window 22. The inspection lights 21 on the inner top wall of the integrated box 6 provide sufficient lighting when inspecting the inside of the integrated box 6, making it convenient for operators to work. The heat dissipation window 22 on the right side of the integrated box 6 forms a good heat dissipation system, which can dissipate the heat generated during the operation of the equipment in a timely manner, and avoid the performance and service life of the equipment due to excessive temperature.

[0023] The working principle of this utility model is as follows: When using this device, the operator first uses the mounting holes 4 and fastening screws 5 to fix the fixed frame 1 to the wall. Then, bolts are used to install the integrated box 6 to the two connecting strips 2. Subsequently, the hooks 3 on the back of the two connecting strips 2 are used to hang them on the fixed frame 1, thus completing the quick installation of the integrated box 6. At this point, the device can be used normally. During use, the photovoltaic control module 11 is installed inside the box 9 and arranged separately by the partition plate 10. The DC input socket 12 is connected to the DC power generated by the photovoltaic module, with the positive input terminal 1201 connected to the photovoltaic module. The positive terminal and the negative terminal 1202 are connected to the negative terminal of the photovoltaic module. After processing the input DC power, the photovoltaic control module 11 outputs the processed DC power through the DC output socket 13. The DC output positive terminal 1301 and the output negative terminal 1302 are respectively connected to the corresponding electrodes of the load or energy storage device. When the photovoltaic control module 11 needs to be maintained or replaced, the operator opens the sealing door 7 through the door handle 8, unscrews the positioning bolt 15, and then uses the module handle 16 to pull out the photovoltaic control module 11 that needs to be maintained or replaced, so that the photovoltaic control module 11 can be repaired or replaced. The above is the complete operation process of this device.
