Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a system for providing sunshade, rain protection and heat dissipation for outdoor photovoltaic inverters. Background Technology

[0002] A photovoltaic inverter is a power regulation device composed of semiconductor devices, mainly used to convert direct current (DC) power into alternating current (AC) power. It generally consists of a boost circuit and an inverter bridge circuit. The boost circuit increases the DC voltage of the solar cells to the DC voltage required for the inverter's output control; the inverter bridge circuit then converts the boosted DC voltage into an equivalent AC voltage of the commonly used frequency.

[0003] Photovoltaic inverters are generally installed outdoors and are affected by natural factors such as sunlight, rain, dust, and high temperatures. Therefore, the heat dissipation performance of photovoltaic inverters has become one of the main factors affecting their stable and reliable operation. There are two methods for inverter heat dissipation: one is natural heat dissipation, which relies on its own heat sink; the other is to use a cooling fan to force cooling. During operation, the IGBTs and other components inside the photovoltaic inverter generate a large amount of heat. If this heat cannot be dissipated in time, the power device chips will overheat, the junction temperature will rise, affecting the device's performance, reducing system reliability, and even damaging the devices.

[0004] When the internal temperature of the inverter exceeds the safety threshold, the system will activate the over-temperature protection mechanism, automatically reducing the output power to prevent overheating, which directly affects power generation. Especially during the high-temperature period of summer, the inverter's over-temperature protection not only affects system power generation but may even damage the inverter. Utility Model Content

[0005] The purpose of this utility model is to provide a system for shading, rain protection, and heat dissipation of outdoor photovoltaic inverters. This system addresses the technical problem that when the internal temperature of the inverter exceeds a safe threshold, the system will activate an over-temperature protection mechanism, automatically reducing the output power to prevent overheating, which directly affects power generation and causes damage to the inverter. The system provides shading, rain protection, and heat dissipation for the photovoltaic inverter, increasing its reliability and extending its lifespan. It can also be used as an emergency power source.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A system for providing shade, rain protection, and heat dissipation for outdoor photovoltaic inverters includes:

[0008] Connecting brackets, sunshade and rainproof power generation panels, photovoltaic controller, storage battery and cooling fan;

[0009] The connecting bracket is installed above the photovoltaic inverter. A sunshade and rainproof power generation panel is installed on the connecting bracket. A photovoltaic controller and a battery are installed below the sunshade and rainproof power generation panel. The cooling fan is welded to the connecting bracket.

[0010] As a preferred embodiment of this utility model, the connecting bracket includes a vertical bracket, a horizontal bracket, and a diagonal brace. The horizontal bracket is located at the upper end of the vertical bracket, and the diagonal brace is supported by the vertical bracket and connected to the horizontal bracket.

[0011] The vertical support, horizontal support, and diagonal brace are integrally formed or welded together.

[0012] In a preferred embodiment of this utility model, the cooling fan is connected to the connecting bracket via a connector;

[0013] One end of the connector is connected to the vertical support, and the other end is connected to the middle of the diagonal support.

[0014] As a preferred embodiment of this utility model, the size of the sunshade and rainproof power generation panel is larger than that of the photovoltaic inverter;

[0015] The sunshade and rain-proof power generation panel includes a sunshade and rain-proof panel and photovoltaic modules or integrated photovoltaic modules mounted on the sunshade and rain-proof panel.

[0016] As a preferred embodiment of this utility model, the sunshade and rainproof panel includes an inclined portion and a vertical portion;

[0017] The inclined portion is located above the horizontal support, and the vertical portion is located on the outside of the vertical support.

[0018] As a preferred embodiment of this utility model, the included angle between the inclined part and the vertical support is 20-90 degrees.

[0019] As a preferred embodiment of this utility model, the photovoltaic controller and the battery are installed below the sunshade and rainproof power generation panel; or

[0020] The photovoltaic control unit and the battery are mounted above the connector.

[0021] As a preferred embodiment of this utility model, the cooling fan is mounted on the connector, and the cooling fan is installed below the sunshade and rainproof power generation panel; or

[0026] As a preferred embodiment of this utility model, the sunshade and rainproof power generation panel is connected to a storage battery.

[0027] The beneficial effects of this utility model are:

[0028] 1. By installing a sunshade and rainproof power generation panel above the photovoltaic inverter, the photovoltaic inverter can be prevented from being exposed to the sun on sunny days and its temperature can be reduced. On rainy days, it can protect the photovoltaic inverter from rain and prevent rainwater from directly washing over it. Through the sunshade and rainproof functions of the power generation panel, the reliability of the photovoltaic inverter can be increased and its lifespan can be extended.

[0029] 2. The connecting bracket, sunshade and rainproof solar panels, photovoltaic controller, battery, and cooling fan form an off-grid micro-storage system. When there is sunlight during the day, the photovoltaic inverter starts to work and generates heat. At this time, the sunshade and rainproof solar panels generate electricity, and the photovoltaic power is prioritized to supply the cooling fan. The cooling fan starts to work to cool down the photovoltaic inverter, and the excess photovoltaic power charges the battery. When the photovoltaic inverter is not working in cloudy or rainy weather or at night, there is no need to cool down the photovoltaic inverter. At this time, the sunshade and rainproof solar panels no longer generate electricity, and the electricity stored in the battery during the day can be used as an emergency power source.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] Example:

[0046] like Figures 1 to 6 As shown, a system for providing sunshade, rain protection, and heat dissipation for an outdoor photovoltaic inverter 7 includes: a connecting bracket 1, a sunshade and rain protection power generation panel 2, a photovoltaic controller 3, a battery 4, and a cooling fan 5. The connecting bracket 1 is mounted above the photovoltaic inverter 7, the sunshade and rain protection power generation panel 2 is mounted on the connecting bracket 1, and the photovoltaic controller 3 and battery 4 are mounted below the sunshade and rain protection power generation panel 2. The cooling fan 5 is welded to the connecting bracket 1. In this embodiment, the photovoltaic controller 3 and battery 4 are housed in a box.

[0047] In this embodiment, the connecting bracket 1 provides support and reinforcement for the sunshade and rain-proof power generation panel 2, thereby improving the stability of the sunshade and rain-proof power generation panel 2.

[0048] like Figures 1 to 6 As shown, the connecting bracket 1 includes a vertical bracket 11, a horizontal bracket 12 and a diagonal bracket 13. The horizontal bracket 12 is located at the upper end of the vertical bracket 11, and the diagonal bracket 13 is supported on the vertical bracket 11 and connected to the horizontal bracket 12. The vertical bracket 11, the horizontal bracket 12 and the diagonal bracket 13 are integrally formed or welded together.

[0049] In this embodiment, the cooling fan 5 is connected to the connecting bracket 1 via a connector 6; one end of the connector 6 is connected to the vertical bracket 11, and the other end is connected to the middle of the inclined support bracket 13, thereby improving the stability of the cooling fan 5.

[0050] In this embodiment, the size of the sunshade and rainproof power generation panel 2 is larger than that of the photovoltaic inverter 7, so that it can cover the photovoltaic inverter 7 and play the role of sunshade and rainproof; the sunshade and rainproof power generation panel 2 includes a sunshade and rainproof panel 21 and a photovoltaic module 22 disposed on the sunshade and rainproof panel 21.

[0051] The sunshade and rainproof panel includes an inclined part 211 and a vertical part 212; the inclined part 211 is located above the horizontal support 12, and the vertical part 212 is located on the outside of the vertical support 11.

[0052] The angle between the inclined part 211 and the vertical support is 20-90 degrees, preferably 30° to 80°, which can ensure that rainwater and snow slide off quickly and avoid accumulation while providing shade and rain protection. When the photovoltaic inverter 7 is installed on a wall or other location where the back of the photovoltaic inverter 7 is obstructed, the sunshade and rain protection power generation panel 2 only needs to be installed with the inclined part 211. When the photovoltaic inverter 7 is installed on a bracket or other location where the back of the photovoltaic inverter 7 is unobstructed, the sunshade and rain protection power generation panel 2 needs to be installed with both the inclined part 211 and the vertical part 212.

[0053] like Figures 1 to 5 As shown, the photovoltaic controller 3 and the battery 4 are installed below the sunshade and rainproof power generation panel 2; or the photovoltaic controller is installed above the connector 6.

[0054] like Figures 5 to 6 As shown, the cooling fan 5 is mounted on the connector 6, and the cooling fan 5 is installed below the sunshade and rainproof power generation panel 2; or the cooling fan 5 is located above the photovoltaic inverter 7; in this embodiment, the number of cooling fans 5 is one or more.

[0055] In this embodiment, the connector 6 is welded to the vertical support 11 and the diagonal support 13; the connector 6 has a window 61 and a mounting hole 62 that match the cooling fan 5, and the cooling fan 5 is connected to the connector 6 by screws; the sunshade and rainproof power generation panel 2 is connected to the battery 4. Through the battery 4, when there is sunlight during the day, the photovoltaic inverter 7 starts to work and generates heat. At this time, the sunshade and rainproof power generation panel 2 generates electricity, and the photovoltaic power generation is preferentially supplied to the cooling fan 5. The cooling fan 5 starts to work to cool down the photovoltaic inverter 7, and the excess photovoltaic power charges the battery 4; when the photovoltaic inverter 7 does not work in cloudy or rainy weather or at night, there is no need to cool down the photovoltaic inverter 7. At this time, the sunshade and rainproof power generation panel 2 no longer generates electricity, and the electricity stored in the battery 4 during the day can be used as an emergency power source.

[0056] In summary: By installing the sunshade and rainproof power generation panel 2 above the photovoltaic inverter 7, the inverter 7 can be protected from direct sunlight and its temperature reduced on sunny days. On rainy days, it can shield the inverter 7 from rain and prevent rainwater from directly washing over it. The sunshade and rainproof functions of the power generation panel 2 increase the reliability and extend the lifespan of the photovoltaic inverter 7. The connecting bracket 1, the sunshade and rainproof power generation panel 2, the photovoltaic controller 3, the battery 4, and the cooling fan 5 form an off-grid micro-storage system. When there is sunlight during the day, the photovoltaic inverter 7 starts working and generates heat. At this time, the sunshade and rainproof power generation panel 2 generates electricity, which is preferentially supplied to the cooling fan 5. The cooling fan 5 then works to cool the photovoltaic inverter 7, and excess photovoltaic power charges the battery 4. When the photovoltaic inverter 7 is not working during cloudy or rainy weather or at night, there is no need to cool it down. In this case, the sunshade and rainproof power generation panel 2 stops generating electricity, and the electricity stored in the battery 4 during the day can be used as an emergency power source.
