[0004] However, most existing controllers directly insert the wires into the wiring holes, which can be susceptible to detachment due to external factors, thus affecting charging and discharging operations. For example, the aforementioned comparative document uses this method, where the wires are directly inserted into the wiring holes. In practical applications, when the wiring holes are not in use, they are exposed, allowing dust to enter and affecting operation. Furthermore, the wiring is easily pulled apart later on, affecting charging and discharging. Therefore, those skilled in the art provide a high-power solar multi-functional protective charging and discharging controller to solve the problems mentioned in the background art.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a technical solution for a high-power solar multi-functional protection charge and discharge controller, comprising: a controller body 1, which is composed of a first controller housing 11 and a second controller housing 12 from top to bottom. The upper surface of the first controller housing 11 is symmetrically provided with wiring holes 2, and the front surfaces of the first controller housing 11 and the second controller housing 12 are both equipped with mounting plates 3. The front surface of the mounting plate 3 is fixed with a stabilizing plate 32, and the upper surface of the mounting plate 3 is snapped with a positioning plate 31. The rear surface of the positioning plate 31 is provided with a wire-holding groove 311 above the wiring hole 2. This setting uses the wire-holding groove 311 to hold the wire after wiring in the wiring hole 2, thereby ensuring the stability of the wire and preventing it from falling off and affecting the charging and discharging operation.

[0024] The lower surface of the first controller housing 11 is symmetrically provided with mounting guide blocks 41, and the upper surface of the second controller housing 12 is provided with mounting groove 4. This arrangement allows the first controller housing 11 and the second controller housing 12 to be quickly installed and disassembled by sliding the mounting guide blocks 41 inside the mounting groove 4, so as to facilitate the maintenance of the internal parts of the controller body 1.

[0025] like Figure 1 As shown, screws are symmetrically arranged on the front surface of the mounting plate 3 below the stabilizing plate 32, and the mounting plate 3 is installed on the front surface of the second controller housing 12 by screws. This arrangement uses screws to facilitate the installation of the mounting plate 3 and the second controller housing 12, so as to facilitate the subsequent clamping of the wires.

[0026] like Figure 2 As shown, the wire-locking groove 311 and the wiring hole 2 are correspondingly matched and adapted to each other. The wire-locking groove 311 is semi-circular. This setting allows the wire to be locked into the wire-locking groove 311 after wiring, thus preventing the wire from falling off.

[0027] like Figure 2 and Figure 3 As shown, the upper surface of the stabilizing plate 32 is symmetrically provided with positioning pins 321, and the lower surface of the positioning plate 31 is provided with positioning holes 312 that engage with the positioning pins 321. This arrangement utilizes the positioning pins 321 to be embedded into the positioning holes 312 at different positions, thereby enabling the positioning plate 31 to shield and protect the wiring hole 2.

[0028] like Figure 4 and Figure 5As shown, the mounting guide block 41 is T-shaped on the lower surface of the first controller housing 11 and is slidably installed inside the mounting groove 4. The lower surface of the second controller housing 12 is also symmetrically provided with positioning bolts 42. The lower surface of the mounting guide block 41 is provided with a connecting hole. The end of the positioning bolt 42 is embedded in the connecting hole and threadedly connected to the connecting hole. This arrangement allows the first controller housing 11 and the second controller housing 12 to be installed and disassembled by sliding the mounting guide block 41 inside the mounting groove 4. The positioning bolts 42 ensure the stability of the mounting guide block 41 after installation.

[0029] The working principle of this utility model is as follows: When using this high-power solar multi-functional protection charge and discharge controller, the mounting plate 3 is first installed on the front surface of the second controller housing 12 with screws. After installation, the positioning plate 31 can be installed by embedding the positioning pin 321 into the positioning hole 312. During installation, the wiring hole 2 and the wire slot 311 correspond to each other. When the controller body 1 is electrically connected to the photovoltaic panel, the battery and the lighting device, the wire can be inserted into the wiring hole 2 and then the wire can be inserted into the wire slot 311. This ensures the stability of the wire and prevents it from falling off and affecting the charging and discharging work. At the same time, when the wiring hole 2 is not used, the positioning pin 321 can be embedded into the positioning hole 312 opened at other positions on the lower surface of the positioning plate 31. This allows the positioning plate 31 to shield and protect the wiring hole 2, preventing the wiring hole 2 from being exposed and causing dust to enter and affect subsequent use.

[0030] Meanwhile, when it is necessary to maintain the circuit board inside the controller body 1, simply rotate the positioning bolt 42 on the lower surface of the second controller housing 12 to separate the positioning bolt 42 from the mounting guide block 41. After separation, simply slide the first controller housing 11 on the upper surface of the second controller housing 12, that is, slide the mounting guide block 41 inside the mounting groove 4 to disassemble the first controller housing 11 and the second controller housing 12 for maintenance of their internal circuit boards. The structure is simple and practical.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
