[0002] As a key component of energy storage systems, the household energy storage gateway control box plays a crucial role in integrating data from photovoltaic inverters, battery packs, and household loads to achieve energy management strategies such as self-consumption or grid connection of surplus electricity. Currently, these control boxes generally employ a layout structure that uses wires and copper busbars for internal connections and provides users with fence terminal interfaces. However, this existing structure results in a large amount of exposed and messy wiring inside the control box, affecting not only the overall aesthetics but also posing safety hazards. Furthermore, users need to crimp the OT terminals themselves during wiring, a cumbersome and complex process that leads to a poor user experience. In addition, because this structure lacks integrated necessary control shutdown functions, users must add an external, independent control shutdown device, significantly increasing installation complexity and overall cost. Therefore, the existing structure suffers from problems such as messy wiring, cumbersome wiring operations, and high costs. Utility Model Content

[0031] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail below.

[0032] This application provides a user storage gateway control box structure, which adopts the following technical structure:

[0033] Reference Figure 1 and Figure 2The user storage gateway control box structure includes a box body 1 and a cover 2. One side of the cover 2 is hinged to the box body 1 for opening and closing. The box body 1 has a hollow cuboid structure. A panel 11 is installed on the side of the box body 1 near the cover 2 by screws. The panel 11 and the other side walls of the box body 1 form an internal cavity for installing various components. The interior of the box body 1 adopts a layered layout structure, divided into three vertical spaces according to their position: upper, middle and lower. The functional areas include a main control area 3, a wiring area 4, a sub-control area 5 and a communication area 6. The main control area 3 is located in the upper part of the box body 1 and is equipped with a main circuit breaker 31, such as a Generator air switch. The wiring area 4 is located in the upper part of the box body 1 and is arranged horizontally alongside the main control area 3. The wiring area 4 is equipped with multiple quick-connect terminals 41, which are connected in parallel with the main circuit breaker 31, directly replacing the traditional fence terminal structure. Specifically, the quick-connect terminals 41 include, but are not limited to, PV input terminals, bypass terminals, grid terminals, and generator terminals, such as PV quick-connect terminals, Part quick-connect terminals, Cti quick-connect terminals, and Sma quick-connect terminals, enabling direct insertion of bare wires without crimping. The control area 5 is located in the middle of the enclosure 1. A laterally extending guide rail 51 is installed within the control area 5. Multiple functional circuit breakers 52 are detachably mounted on the guide rail 51. Each functional circuit breaker 52 is connected to a corresponding quick-connect terminal 41, enabling independent parallel connection of each line. This completely eliminates the problem of cable tangling in traditional solutions. Specifically, the functional circuit breakers 52 include, but are not limited to, grid access circuit breakers, whole-house load circuit breakers, emergency backup circuit breakers, and generator input circuit breakers, such as AIO air switches, general air switches, bypass air switches, and grid air switches, forming a main-to-branch circuit protection architecture. Additionally, in this embodiment, an expansion slot is reserved on the left side of the guide rail 51 for users to add circuit breakers, meeting personalized expansion needs. Communication area 6 is located at the bottom of enclosure 1. Communication board 61 is installed in communication area 6. Communication board 61 is a circuit board. Communication board 61 is equipped with main control chip (such as MCU chip) and communication module (such as WIFI module or 4G module). Communication board 61 is connected to the data interface of quick-connect terminal 41 and the control terminal of functional circuit breaker 52 through cable to realize data acquisition and circuit breaker status monitoring, and provide real-time data support for energy strategy optimization.

[0034] Between different functional areas, the main control area 3 and the wiring area 4 are connected by copper busbars, and the wiring area 4 and the sub-control area 5 are connected by wires. The output of the quick-connect terminal 41 is connected to the input of the functional circuit breaker 52 by wires. The output of the functional circuit breaker 52 is connected to external devices. The communication area 6 is connected to each area via signal cables. In the above control box, through the partitioned layout and the design of the quick-connect terminal 41, multiple sets of external lines can be connected to the control box in the same area at the same time, effectively reducing the wiring steps for users. At the same time, each line has an independent built-in circuit breaker, thereby saving users the cost of installing additional shutdown equipment. Furthermore, the independent line correspondence and neat arrangement of wires result in an aesthetically pleasing structure, which can effectively improve the efficiency of fault diagnosis.

[0035] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 2 The main control area 3 is also equipped with an electricity meter 32 and a surge protector 33. The electricity meter 32, surge protector 33 and the main circuit breaker 31 are connected in series through the same copper busbar to form an integrated monitoring and protection unit. It can not only directly measure the input / output power of the power grid, but also build the shortest overvoltage discharge path through the surge protector 33, which significantly improves the safety of the system.

[0036] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 2 The multiple quick-connect terminals 41 in the wiring area 4 are spring-loaded terminals, such as the WAGO773 series. Users can connect the line by inserting the line into the corresponding port, completely eliminating the traditional crimping OT terminal operation. In practical applications, the single-line connection time is reduced from 3 minutes to 30 seconds, and the contact resistance is stable at <5mΩ. This not only simplifies the user's operation steps and improves the user experience, but also eliminates the risk of overheating caused by poor crimping.

[0037] In the preferred embodiment of this application, reference is made to Figure 2 A communication cover plate 7 is fixedly connected to the top of the communication board 61 by screws. The communication cover plate 7 and the other side walls of the housing 1 form a wiring cavity. The communication cables of the communication board 61 are all connected to other components through the wiring cavity to form a shielding structure, which reduces the communication error rate caused by high-frequency noise interference from the inverter. Moreover, during maintenance, only the baffle plate 1 needs to be removed without disturbing other components.

[0038] In the preferred embodiment of this application, reference is made to Figure 2 The circuit breaker cover plate 8 is fixedly connected to the top of the control area 5 by screws. The circuit breaker cover plate 8 shields the connecting metal piece of the functional circuit breaker 52, physically isolating the risk of the user touching the live metal piece during operation, and at the same time preventing creepage accidents caused by dust accumulation on the metal piece.

[0039] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 2The top of the enclosure 1 has an access hole 12, through which all external wires pass into the enclosure 1 and connect to the corresponding components. The bottom of the enclosure 1 has two rows of equally spaced outlet holes 13, through which each wire in the enclosure 1 passes out from a corresponding outlet hole 13 and connects to external equipment. The multiple wires are clearly arranged, avoiding signal interference and improving maintenance efficiency.

[0040] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 2 A WiFi reset button 14 is installed on the top of the panel 11 of the housing 1. The mechanical contacts of this button are directly connected to the BOOT reset pin of the main control chip on the communication board 61. When the button is pressed, the main control chip sends a low-level pulse to the communication module, triggering a hardware restart of the communication module to restore the network from abnormal state. Physical reset solves the communication interruption problem caused by software crashes, and the response speed is improved compared to the software reset solution.

[0041] In the preferred embodiment of this application, reference is made to Figure 1 and Figure 2 The top of the enclosure 1 is equipped with a communication status indicator light 15, which is electrically connected to the communication board 61. The status of the communication status indicator light 15 includes constant light, slow flashing, fast flashing, and off, corresponding to network statuses such as normal communication, data transmission in progress, network abnormality, and device power failure, respectively. Through hardware-level status mapping, users can accurately identify fault types, effectively improving fault location efficiency.

[0042] In the preferred embodiment of this application, reference is made to Figure 2 The enclosure 1 is also equipped with a grounding copper busbar 9, which is located at the bottom of the enclosure 1. The grounding copper busbar 9 is connected to the ground wire and connects to the grounding terminals of all functional circuit breakers 52 through a metal plate, replacing the traditional scattered and messy grounding wires. This not only saves on wire costs but also makes the wiring inside the enclosure more aesthetically pleasing.

[0043] The application process and implementation principle of this application embodiment are as follows: During user installation, external power lines, photovoltaic input lines, load lines, and other wires are introduced through the access hole 12 on the top of the enclosure 1 and connected to the corresponding spring-loaded quick-connect terminal 41 in the wiring area 4, achieving a quick and reliable connection without crimping. The output wires from the quick-connect terminal 41 are connected to the input terminals of the corresponding functional circuit breakers 52 on the guide rail 51 of the sub-control area 5. The output wires of the functional circuit breakers 52 are connected to external devices, such as photovoltaic inverters and household loads, through the outlet hole 13 at the bottom of the enclosure 1. The main circuit breaker 31 of the main control area 3 is connected in parallel with the wiring area 4 through a copper busbar and provides overall protection for the entire system. The series-connected electricity meter 32 is used for metering, and the surge protector 33 provides overvoltage protection. The communication board 61 collects data and status of each quick-connect terminal 41 and functional circuit breaker 52 through signal cables and realizes remote monitoring and energy management strategy execution through the WiFi module. The WiFi reset button 14 and the communication status indicator 15 provide convenient network management and status feedback. This structure, through its partitioned layout, spring-loaded quick-connect terminals 41, and integrated functional circuit breaker 52, significantly simplifies wiring operations, eliminates internal cable tangling, and results in neat and aesthetically pleasing cabling. Simultaneously, the built-in functional circuit breaker 52 directly integrates necessary control and shutdown functions, saving users the steps and costs of installing separate shutdown devices. The communication cover 7 and circuit breaker cover 8 respectively shield the communication cables and the live metal contacts of the functional circuit breaker 52, enhancing safety and anti-interference capabilities. The grounding copper busbar 9 provides centralized and reliable grounding protection. Therefore, this household power storage gateway control box structure effectively solves the problems of messy wiring, cumbersome wiring operations, and high costs in existing technologies.

Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
