Description

Technical Field

[0001] This utility model relates to the field of integrated photovoltaic and energy storage technology, specifically an outdoor integrated photovoltaic and energy storage machine that is easy to wire and waterproof. Background Technology

[0002] A photovoltaic-storage integrated unit is a device that deeply integrates photovoltaic power generation and energy storage technologies. Through integrated design, it achieves efficient conversion, storage and intelligent scheduling of solar energy. A photovoltaic-storage integrated unit installed outdoors is called an outdoor photovoltaic-storage integrated unit. It mainly includes components such as inverter modules, battery packs and input / output modules, which are usually installed in a single housing.

[0003] Because of their outdoor environment, they are inevitably exposed to rainfall. Therefore, to prevent rain damage and achieve insulation, waterproof connectors are usually installed at the input and output wiring points to achieve a good waterproof effect. However, the wiring is all done inside the housing, which either needs to be done simultaneously with the assembly of internal components, or the side panels or covers on the housing need to be removed during subsequent field wiring. This not only increases the workload, but the wire ends also occupy the internal space of the housing, affecting the effective heat dissipation of internal components, especially the inverter module.

[0004] Furthermore, during operation, the inverter module generates power consumption and heat due to current conversion and the operation of electronic components. This is especially true for components such as MOSFETs and IGBTs in high-power inverter modules, which produce significant heat during operation. Insufficient heat dissipation can lead to overheating, potentially damaging these components or even causing circuit malfunctions. Therefore, effective heat dissipation is essential. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects and deficiencies of the existing technology and provide an outdoor integrated photovoltaic and energy storage unit that is easy to wire and waterproof. It is convenient to wire and ensures effective heat dissipation of internal components, especially the inverter module. It can also effectively prevent rainwater and ensure the normal output of input and output wiring.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An outdoor photovoltaic and energy storage integrated unit that is easy to wire and waterproof includes a housing, an inverter module, a battery pack, and an input / output module. The unit is characterized in that: a window is provided on one side wall of the housing, the input / output module is installed in the window, an outer cover is installed on the outside of the window, and an opening is provided at the bottom of the outer cover for leading out the input and output wires of the input / output module.

[0007] Furthermore, the input / output module includes a mounting panel and input and output terminals fixed to the mounting panel.

[0008] Furthermore, an annular mounting plate is fixed inside the window. The four corners of the inner edge of the annular mounting plate are respectively provided with first screw holes, and the four corners of the mounting panel are respectively provided with second screw holes. Bolts are screwed into the corresponding second screw holes and first screw holes from the outside to the inside in sequence, for installing the input / output module in the window.

[0009] Furthermore, the top and both sides of the outer edge of the annular mounting plate are integrally connected with wing edges, which are exposed outside the window.

[0010] Furthermore, the outer cover includes an outer cover plate, the top and both sides of which are integrally connected with Γ-shaped flanges, the Γ-shaped flanges on both sides are respectively slidably fitted onto the wings on both sides, and the inner wall of the Γ-shaped flange at the top abuts against the outer edge of the wing at the top.

[0011] Furthermore, the opening is formed in the space between the bottom end of the outer cover plate and the bottom end of the annular mounting plate.

[0012] Furthermore, the interior of the housing is divided into an inverter compartment at the top and a battery compartment at the bottom. The inverter module and the battery pack are respectively installed in the inverter compartment and the battery compartment. An air inlet is provided on the side wall of the housing on the side corresponding to the inverter compartment. A fan is installed inside the air inlet.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model installs the input / output module on the side wall of the housing. During assembly, only the internal wiring (the wiring between the components) needs to be completed. The external wiring can be completed on site, which is convenient for wiring and will not occupy the internal space of the housing due to a large number of wire ends.

[0033] In this invention, an opening 7 is formed in the space between the bottom end of the outer cover plate 61 and the bottom end of the annular mounting plate 8.

[0034] In this invention, the interior of the housing 1 is divided into an inverter compartment 12 located at the top and a battery compartment 13 located at the bottom. The inverter module 2 and the battery pack 3 are respectively installed in the inverter compartment 12 and the battery compartment 13. An air inlet 14 is provided on the side wall of the housing 1 on the side corresponding to the inverter compartment 12. A fan 15 is installed inside the air inlet 14. An opening 16 is provided at the bottom of the other side of the inverter compartment 12 to connect the inverter compartment 12 and the battery compartment 13, thereby providing a channel for heat dissipation of the inverter module 2 and providing internal wiring through holes for the inverter module 2 and other internal components, such as the battery pack 3 and the input / output module 4.

[0042] Then, complete the signal line connections between the internal components, such as inverter module 2, battery pack 3, and input / output module 4, the signal line connections with input terminal 42 and output terminal 43, and the power line connection with power socket 44.

[0043] After completing the internal wiring, the top cover 102 and the rear side plate 103 are fixedly connected to the U-shaped side plate 101 respectively.
