[0002] With the continuous advancement of new energy development policies and the rapid expansion of the photovoltaic energy storage market, the integrated and modular design of energy storage equipment has become an industry trend. Currently, a large number of photovoltaic energy storage modules are integrated into containerized equipment to meet the requirements of convenient transportation, flexible deployment, and strong environmental adaptability. However, due to the enclosed structure of containers, their internal space is relatively sealed, making it difficult for external light to enter. Especially at night, in underground locations, or in harsh weather conditions with insufficient light, the internal lighting of containers is extremely dim, seriously affecting the daily operation, maintenance, loading, unloading, repair, and inventory work of the internal equipment.

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0043] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0044] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

[0046] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0047] With the advancement of "dual carbon" goals and the continuous strengthening of new energy industry policies, the integrated application of photovoltaic power generation and energy storage modules is becoming increasingly widespread. Among them, containerized photovoltaic energy storage modules are gradually becoming the mainstream integration form in photovoltaic energy storage projects due to their advantages such as compact structure, convenient transportation, and flexible deployment. This type of system typically integrates key equipment such as inverters, battery packs, and electrical control devices into a container structure, and is widely used in scenarios such as power peak shaving, new energy grid connection, and emergency power supply to the grid.

[0048] However, due to the highly sealed structure of containers, their internal space is enclosed, making it difficult to obtain natural light unless external doors are opened or active lighting is provided. When operators need to enter the container at night, on rainy days, in underground locations, or in poorly lit environments to perform installation, commissioning, equipment inspection, operation and maintenance, material loading and unloading, or inventory checks, they often face the problem of insufficient lighting conditions.

[0049] In one embodiment, refer to the appendix to the specification. Figure 1 This application describes an integrated photovoltaic and energy storage device that can solve the problems in the prior art, provide stable lighting, and thus facilitate operators in installing and maintaining the equipment.

[0050] Reference manual attached Figure 1 and Figure 2 The photovoltaic-storage integrated device provided in this application includes a container 1, a photovoltaic power generation system, an energy storage module 3, a lighting module 4, and an inverter 7. The container 1 has an installation space 10 and at least one through-hole connected to the installation space 10, which is used to accommodate key components including the energy storage module 3 and an electrical control module.

[0051] A photovoltaic power generation system is installed on at least one side of container 1, including a tracking bracket 6 and photovoltaic modules 2 mounted on the tracking bracket 6. The tracking bracket 6 further includes a main shaft 61 and a drive device 62, with the drive device 62 installed within the installation space 10. The photovoltaic modules 2 are fixed to the side of the main shaft 61 away from container 1. The main shaft 61 is a transmission structure for supporting and rotating the photovoltaic modules 2; one end of it passes through a through-hole on container 1 and is connected to the drive device 62 inside container 1, thereby enabling the photovoltaic modules 2 to rotate and adjust under the drive of the tracking bracket 6, maximizing solar energy collection efficiency.

[0052] Understandably, the drive unit 62 is fixedly installed within the installation space 10 of the container 1, and the main shaft 61 and the drive unit 62 are connected by a transmission mechanism. This connection can generally be achieved through gear meshing, couplings, or sprocket structures. In this embodiment, the specific method of transmission connection is not limited; in actual implementation, it can be selected according to specific needs to ensure efficient and stable transmission under different power requirements or torque transmission scenarios. Furthermore, the drive unit 62 being located within the installation space 10 effectively isolates it from adverse environmental factors such as wind, rain, and dust, extending its service life. It also simplifies the external structural design, avoiding impacts on the overall aesthetics and ease of maintenance. Additionally, the robust container structure of the container 1 replaces some of the columns, simplifying the photovoltaic support structure and saving costs.

[0053] Inverter 7 is installed in the installation space 10, and the DC side of inverter 7 is electrically connected to photovoltaic module 2. It is used to convert the DC power output by photovoltaic module 2 into AC power that can be used by loads (such as motors, lighting, electrical equipment), or to step down the high voltage DC power output by photovoltaic module 2 to the charging voltage of energy storage battery.

[0054] The energy storage module 3 is installed within the installation space 10 and electrically connected to the DC side of the inverter 7. It is used to store the surplus electrical energy of the photovoltaic module 2 after meeting the load power supply requirements, and to supply power to the load side under conditions of insufficient sunlight or at night. Preferably, the energy storage module 3 can adopt energy storage units with high safety and high energy density, such as lithium battery packs or lithium iron phosphate batteries, and is equipped with an electronic control module with a battery management system to ensure power supply stability and service life.

[0055] More importantly, the aforementioned lighting module 4 is installed within the installation space 10, such as on the inner wall or top wall. The lighting module 4 is connected to the AC side of the inverter 7, enabling the lighting module 4 to stably obtain the AC power output from the inverter. This provides sufficient lighting support when maintenance personnel enter the container 1 to perform equipment installation, debugging, maintenance, or inventory checks, effectively improving the operation and maintenance efficiency and safety assurance capabilities of the integrated photovoltaic and energy storage equipment.

[0056] Specifically, such as Figure 2 As shown, photovoltaic module 2 collects solar energy and outputs high-voltage direct current (DC). Photovoltaic module 2 is electrically connected to the DC side of inverter 7 installed inside container 1. The DC power is input to inverter 7 for processing, prioritizing the power supply needs of the load side. Specifically, inverter 7 converts the DC power output from photovoltaic module 2 into alternating current (AC) to power loads such as lighting module 4. Energy storage module 3 is electrically connected to the DC side of inverter 7 to supplement energy storage after the load power supply needs are met. In other words, inverter 7 steps down the high-voltage DC power output from photovoltaic module 2 to the battery charging voltage of energy storage module 3 to store excess electrical energy generated by photovoltaic module 2. During periods of insufficient sunlight or at night, loads such as lighting module 4 can draw power from energy storage module 3. In other words, inverter 7 converts the DC power output from energy storage module 3 into AC to achieve continuous power supply capability for the integrated photovoltaic and energy storage system.

[0057] It should be noted that the lighting module 4 can use LED light sources and can integrate a sensing unit to achieve automatic control of turning on or off, thereby improving the system's intelligence level.

[0058] Through the structural configuration of this embodiment, the photovoltaic-storage integrated equipment uses the photovoltaic power generation system as an independent power source. Combined with the energy storage module 3, this enables the lighting system to operate independently of the external power grid, making it suitable for remote areas, field operations, emergency scenarios, and other environments where conventional power access is unavailable. Furthermore, the lighting module 4 is integrated inside the container 1, effectively improving the visibility of equipment inside the container at night or in enclosed environments, reducing misoperation, and enhancing operational efficiency and safety.

[0059] Based on the above embodiments, in other embodiments, the photovoltaic module 2 can also be fixedly installed on the top of the container to further improve power generation efficiency.

[0060] Optionally, the lighting module 4 is installed on the internal side wall or internal top wall of the container 1. It is understood that this installation method fully utilizes the internal structural surface of the container, does not occupy floor space, avoids spatial conflicts with internal devices such as the energy storage module 3, and facilitates efficient integration and wiring optimization. Simultaneously, the side wall and top wall, as fixed structures on the container 1, possess good rigidity and installation strength, facilitating the stable installation and long-term use of the lighting module 4.

[0061] In one embodiment, the lighting module 4 is at least located in the area where the energy storage module 3 and the inverter 7 are located, and is used for the operation panel of the lighting energy storage module 3 and the inverter 7.

[0062] Of course, lighting modules 4 can also be installed at the corners of container 1 to improve the uniformity of lighting.

[0063] In one embodiment, such as Figure 2 and Figure 3 As shown, container 1 has a first sidewall 101 and a second sidewall 102 arranged along the width direction. The first sidewall 101 and the second sidewall 102 are arranged opposite to each other and are adjacent to the opening 100 of container 1. The energy storage module 3 and the inverter 7 are arranged close to the first sidewall 101. The lighting module 4 includes a first lighting component 41, which is arranged close to the second sidewall 102 to illuminate the operation panel of the energy storage module 3 and the inverter 7.

[0064] Combination Figure 2 and Figure 3 As can be seen, the energy storage module 3 is located close to the first side wall 101, and there is an operating space between the first side wall 101 and the second side wall 102 for personnel to pass through, stand or carry out maintenance work. When performing daily maintenance, troubleshooting or equipment inspection, the operator can enter the container 1 through the opening 100 and stand or walk safely in front of the energy storage module 3, avoiding the feeling of spatial oppression or safety hazards caused by the equipment being too close to the wall.

[0065] Understandably, by arranging light sources on the sidewalls opposite to the energy storage module 3 and the inverter 7, it is possible to achieve forward illumination of key parts such as the front operating surface and indicator panel of the energy storage module 3 and other equipment, which can significantly improve the clarity of identification and the accuracy of operation at night or in low light environments.

[0066] Furthermore, the energy storage module 3 inside container 1 typically integrates multiple battery clusters, conversion devices, power management modules, and corresponding operation panels. The operation panel centrally houses a status display unit, function buttons, indicator lights, and an emergency stop switch, representing a frequently used functional area. The lighting module 4 is strategically placed in this area to ensure that operators can accurately identify and operate the relevant function buttons even in low-light conditions or when external lighting fails, preventing safety risks or abnormal equipment shutdowns due to misoperation.

[0067] Based on the above embodiments, in one embodiment, such as Figure 6 As shown, the number of first lighting components 41 is three or more, and they are arranged at intervals along the length of container 1, which can illuminate different areas inside container 1 to meet the lighting needs of a large space inside container 1. This not only enhances the overall brightness level, but also improves the uniformity and reliability of the lighting system.

[0068] Understandably, the spaced arrangement of the first lighting components 41 can effectively expand the lighting coverage, so that different areas inside the container 1 can be illuminated, avoiding uneven illumination caused by concentrated or monotonous lighting fixtures.

[0069] Meanwhile, the spaced first lighting components 41 also facilitate flexible adjustment of lighting intensity and lighting range according to usage needs, enabling independent control of areas and improving the system's intelligence level and energy efficiency.

[0070] It should be noted that, as Figure 1 As shown, container 1 has an opening 100. Under normal circumstances, this opening 100 is used for the installation of internal components, access for maintenance personnel, or natural ventilation of the container's interior environment. The opening 100 connects to the installation space 10. In actual use, the area near the opening 100 is relatively bright due to external natural light, while the deeper interior area away from the opening 100 is often in a state of low light or even no light due to structural obstruction. Especially at night or in inclement weather conditions, the visibility in this area is severely insufficient, causing great inconvenience to daily equipment inspection, abnormal handling, and manual operation in emergency situations.

[0071] In one embodiment, such as Figure 10As shown, container 1 has a door 11 along its length. The door 11 is usually located on one end face of container 1 and corresponds to the opening 100 of container 1 mentioned above. The two work together to form a passage for assembly personnel to enter and exit.

[0072] In this embodiment, please refer to the appendix to the specification. Figure 2 The lighting module 4 also includes at least one second lighting component 42. The second lighting component 42 is disposed in the area of ​​the container 1 away from the door 11, specifically it can be installed on the end wall opposite to the door 11, in the top area near the end wall, or in the side wall near the depth of the container 1.

[0073] Thus, by setting a second lighting component 42 at the end away from the container door 11, the lighting needs of the interior of the container 1 can be met, enabling targeted lighting of the weak or dark areas inside the container 1, improving the uniformity and visibility of the lighting inside the container 1, and helping assembly personnel to perform wiring, connection, testing or maintenance operations in a better lighting environment, thereby reducing safety hazards.

[0074] In addition, the number and arrangement of the second lighting components 42 can be flexibly configured according to factors such as the length of the container 1 and the division of internal functional areas. For example, multiple second lighting components 42 can be set up and distributed at intervals along the height or length direction to further expand the lighting coverage and meet the actual needs of different work areas.

[0075] In one embodiment, container 1 has a top plate 103 and a bottom plate 104 arranged opposite each other along the height direction. The energy storage module 3 is disposed on the bottom plate 104 near the first side wall 101, the inverter 7 is disposed on the first side wall 101, and the first lighting component 41 is disposed on the second side wall 102 near the top plate 103, forming a downward lighting path for the operation panel of the energy storage module 3 and other equipment, avoiding light obstruction caused by maintenance personnel standing to operate, thereby improving the convenience and safety of operation.

[0076] Furthermore, in one embodiment, the second lighting component 42 is disposed on the side of the first sidewall 101 near the top plate 103 and arranged in an area away from the container door 11, for providing effective lighting to the low-light or no-light areas deep inside the container, ensuring that personnel can work safely even in low-light conditions.

[0077] Alternatively, in another optional embodiment, the first lighting component 41 is disposed on the side of the top plate 103 near the second side wall 102, and the second lighting component 42 is disposed on the side of the top plate 103 near the first side wall 101, with the second lighting component 42 located at the end away from the door 11. By arranging the lighting components on the top plate 103, interference from internal equipment or personnel activities on the lighting effect can be further avoided, and the overall lighting uniformity can be improved.

[0078] Understandably, in this embodiment, the spatial layout optimization of the lighting components effectively solves the problem of insufficient visibility caused by lighting blind spots or personnel obstruction in the prior art, and improves the work efficiency and safety of maintenance personnel at night or in low-light environments.

[0079] In practical applications, designers can flexibly adjust the position of the lighting components according to the relative arrangement of the energy storage module 3 and the door 11 in the space to achieve a more targeted lighting coverage effect.

[0080] In one embodiment, based on the above embodiments, such as Figure 4 and Figure 5 The first lighting assembly 41 includes a first lamp body 412 and a first connecting part 411. The first connecting part 411 is fixed to the second side wall 102, and the first lamp body 412 is connected to the first connecting part 411 at a preset position away from the second side wall 102. Similarly, the second lighting assembly 42 includes a second lamp body 421 and a second connecting part 422. The second connecting part 422 is fixed to the side of the first side wall 101 away from the door 11, and the second lamp body 421 is connected to the second connecting part 422 at a preset position away from the first side wall 101.

[0081] It should be noted that, in this embodiment, by setting the first connecting part 411 and the second connecting part 422 as the mounting base, it is beneficial to reliably fix the first lamp body 412 and the second lamp body 421 to the inner wall of the container 1, thereby improving the overall installation strength and seismic performance of the lighting module 4.

[0082] The first connecting part 411 and the second connecting part 422 are preferably made of metal or reinforced engineering plastic. In addition, the first connecting part 411 and the second connecting part 422 can be fixed to the side wall structure inside the container by means of bolts, snap-fit, plug-in or welding, so as to adapt to the installation requirements of different container types.

[0083] In addition, the main body of the lamp is connected to a preset position on the side opposite to container 1 of the corresponding connection part, thereby realizing the effective projection of the lighting source into the interior space of the container. Moreover, the installation height, angle and illumination direction of the lamp can be preset during design or installation to achieve a more reasonable light distribution and avoid problems such as lighting dead spots or local overexposure.

[0084] In this embodiment, the connection method between the connecting part and the container 1 is not specifically limited. Optionally, the connecting part and the container 1 can be connected by a detachable structure, such as plug-in, snap-fit ​​or magnetic connection, which is beneficial for subsequent maintenance or component replacement.

[0085] In one embodiment, please refer to the appendix to the specification. Figure 5The container 1 is also equipped with a cable tray 420 to provide an orderly and safe cable routing path for the lighting module 4. Specifically, the cable tray 420 extends along the length of the container 1 and is respectively located on the first side wall 101 and the second side wall 102, which can improve the overall concealment and integration of the wiring, and make the electrical system more convenient to maintain and structurally safe.

[0086] The first lamp body 412 is mounted on the wiring trough 420 on the first side wall 101 via the first connecting part 411, and the second lamp body 421 is mounted on the wiring trough 420 on the second side wall 102 via the second connecting part 422.

[0087] It should be noted that each connection part can be an independent structure or integrally formed with the wiring trough 420, thereby providing a concealable space for electrical connections while supporting the main body of the lamp, further improving aesthetics and damage resistance.

[0088] The lighting module 4 also includes an electrical connector, one end of which is electrically connected to the AC side of the inverter 7, i.e., AC power signals are output from the inverter 7. The electrical connector extends along the trajectory of the wiring trough 420 to the corresponding output end of the wiring trough 420. After being led out from the output end, it is electrically connected to the first lamp body 412 and the second lamp body 421 respectively, forming a complete power transmission path.

[0089] Through the above-described design, the cable routing of the lighting module 4 can be concealed, avoiding the risks of wear or entanglement caused by exposure, while also facilitating subsequent inspection and maintenance. In container 1, due to the relatively enclosed and complex internal space, the use of pre-installed cable trays 420 helps improve the system's safety and reliability. Simultaneously, the cable trays 420 allow for unified integration of the cable wiring of the lighting modules 4 on both sides, improving installation efficiency and standardization.

[0090] Based on the above, in one embodiment, please refer to the appendix to the specification. Figure 7 The cable tray 420 has a cable outlet end that is connected to the inside of the cable tray 420. The first connecting part 411 and the second connecting part 422 are both fixedly connected to the cable tray 420 through the corresponding cable outlet 4210.

[0091] The electrical connector passes through the first connecting part 411 and extends to the first lamp body 412 to mate with the electrical connection port of the first lamp body 412. Similarly, the electrical connector passes through the second connecting part 422 and extends to the second lamp body 421 to mate with the electrical connection port of the second lamp body 421.

[0092] Specifically, in actual implementation, the first connecting part 411 and / or the second connecting part 422 can adopt flexible components such as corrugated pipes or hoses with hollow structures. One end of the connector is fixed to the wiring trough 420 and connected to the outlet hole 4210 to ensure that the electrical connector in the wiring trough 420 can transition into its own hollow structure. The other end is connected to the electrical input terminal of the lamp body, so that the electrical connector can extend from the inside of the wiring trough 420 to the lamp body through the connecting part.

[0093] Understandably, flexible components have a certain degree of bending resistance and buffering performance, which can effectively reduce the damage to cables caused by environmental vibration, impact or external forces applied during construction, and significantly improve the service life and reliability of lighting systems.

[0094] Of course, in other embodiments, the first connecting part 411 and the second connecting part 422 can also be conventional tubular components, as long as it is ensured that space can be provided for the electrical connector to pass through.

[0095] In one embodiment, the integrated photovoltaic and energy storage device further includes a control module for controlling the on / off states of lamps in different areas of the lighting module 4. Specifically, the control module includes a first control module and a second control module, which are used to control the on / off states of the first lighting component 41 and the second lighting component 42, respectively.

[0096] Specifically, the first control module is electrically connected to the first lighting component 41, and the second control module is electrically connected to the second lighting component 42. Through their respective independent electrical control circuits, operators can switch the on / off state of the first lighting component 41 or the second lighting component 42 according to actual lighting needs, thereby providing a more flexible and zoned lighting control method.

[0097] The first control module and the second control module are respectively located on the first side wall 101 or the second side wall 102 of container 1, near the door 11. This allows maintenance personnel to directly operate the relevant control devices when entering and exiting container 1, without having to cross or go deep into container 1 to control the lighting system, effectively improving the ease of operation and safety. Especially in cases where the internal structure of container 1 is complex and electrical components are dense, it can reduce unnecessary personnel movement and improve maintenance efficiency.

[0098] Furthermore, the lighting can be made more flexible and controllable through the settings of this embodiment. For example, when maintenance work is only required on the side near the energy storage module, only the corresponding lighting component needs to be turned on. Similarly, when it is necessary to inspect the deep area of ​​container 1, the second lighting component 42 can be turned on separately to reduce energy waste and improve system energy efficiency.

[0099] The control module can be implemented by using push-button switches, rotary switches, wireless remote control devices, etc., to adjust the lighting status.

[0100] At the same time, such as Figure 2 As shown, the integrated photovoltaic and energy storage device further includes a distribution box 8, which is electrically connected to the AC side of the inverter 7 and the lighting module 4, respectively, for power distribution and control. Specifically, the inverter 7 converts the DC power generated by the photovoltaic module 2 or the DC power released by the energy storage module 3 into AC power, and outputs it to the distribution box 8 via the AC side. The distribution box 8 then distributes the received AC power to the lighting module 4, thereby driving the normal operation of the various lighting components inside the container 1.

[0101] Furthermore, the distribution box 8 is located on the first side wall 101 so that the first lighting component 41 located on the second side wall 102 can provide positive lighting for equipment such as the energy storage module 3, inverter 7, and distribution box 8, significantly improving the clarity of identification and the accuracy of operation at night or in low light environments.

[0102] In one embodiment, based on the above embodiments, such as Figure 8 As shown, the photovoltaic-storage integrated equipment may also include a fixed support structure 5 and photovoltaic modules 2 installed on the fixed support structure.

[0103] Specifically, the photovoltaic-storage integrated equipment is equipped with a fixed support structure 5, which is connected to the top of the container 1. The photovoltaic modules 2 are installed on the fixed support structure 5 and can also be set at a certain angle to obtain a better solar irradiation angle. In this way, the photovoltaic-storage integrated equipment can combine fixed and tracking photovoltaic supports to improve the solar utilization efficiency.

[0104] Generally, the fixed support structure 5 can be constructed of structural steel, aluminum alloy frames, or other lightweight, high-strength materials, and is secured to the upper surface of the container 1 by welding, bolting, or hinged connections. It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
