[0038] This embodiment provides a photovoltaic inverter protective cover with a simple structure that can be installed and stored by a single person, improving work efficiency; it is also easy to fold and store, reducing transportation costs.

[0039] like Figures 1-4As shown, the photovoltaic inverter protective cover mainly includes a first cover 100, a second cover 200, a first support frame 300, and a second support frame 400. The first support frame 300 and the second support frame 400 are movably connected to two opposite edges of the first cover 100, and the first support frame 300 can rotate around a first direction to fit against the first cover 100, while the second support frame 400 can rotate around a second direction to fit against the first cover 100. The second cover 200 is movably connected to the other edge of the first cover 100, and the second cover 200 can rotate around a third direction to fit against the retracted first support frame 300 and the retracted second support frame 400. The unfolded first support frame 300 and the unfolded second support frame 400 can support the unfolded second cover 200. The first direction is... Figure 2 The X direction in the equation, the second direction is... Figure 2 In the Y direction, the third direction is... Figure 2 The Z direction in the equation.

[0040] Based on the above design, in this embodiment, when the photovoltaic inverter protective cover needs to be folded up, the first support frame 300 can rotate around a first direction to fit against the first cover 100, the second support frame 400 can rotate around a second direction to fit against the first cover 100, and the second cover 200 can rotate around a third direction to fit against the first support frame 300 and the second support frame 400. This achieves the folding and folding function of the photovoltaic inverter protective cover, reducing its volume, facilitating transportation, and lowering transportation costs. When the photovoltaic inverter protective cover needs to be unfolded, the second cover 200 rotates in the opposite direction around the third direction, then the first support frame 300 rotates in the opposite direction around the first direction, and the second support frame 400 rotates in the opposite direction around the second direction, so that the first support frame 300 and the second support frame 400 can support the second cover 200, thereby forming a housing chamber for accommodating the photovoltaic inverter. The photovoltaic inverter protective cover has a simple structure. It can be unfolded or folded simply by rotating the first support frame 300, the second support frame 400 and the second cover 200. The structure is simple and easy to operate, making it easy for a single person to install and store, thus improving work efficiency and saving labor costs.

[0041] The installation of the first support frame 300 and the second support frame 400 can improve the stability and reliability of the photovoltaic inverter protective cover, and reduce or avoid the phenomenon of the photovoltaic inverter protective cover shaking and becoming unstable.

[0042] Optionally, in this embodiment, both the first support frame 300 and the second support frame 400 are configured as "C" shape to reduce weight and save materials, making the photovoltaic inverter protective cover lightweight, flexible, and easy for a single person to install and operate.

[0043] Optionally, in this embodiment, both the first mask 100 and the second mask 200 are solid structures made of panels, which can not only shield the photovoltaic inverter from rain and snow and reduce secondary damage to the photovoltaic inverter from snow accumulation, but also prevent direct sunlight, effectively reduce the temperature of the photovoltaic inverter, improve the working efficiency of the photovoltaic inverter, and enable the photovoltaic inverter to maintain a stable power generation at a certain power.

[0044] For example, in this embodiment, the first cover 100 is a front cover used to shield and protect the front of the photovoltaic inverter; the second cover 200 is a top cover used to shield and protect the top of the photovoltaic inverter.

[0045] like Figures 1-2 As shown, in this embodiment, the first mask 100 has first folded edges 110 on two opposite sides, and second folded edges 120 on the other two opposite sides. The first support frame 300 and the second support frame 400 are both movably connected to the inner walls of the two first folded edges 110; the second mask 200 is movably connected to the outer walls of the two second folded edges 120. The first folded edges 110 facilitate the rotational installation of the first support frame 300 and the second support frame 400, while the second folded edges 120 facilitate the rotational installation of the second mask 200, improving the stability and convenience of installation.

[0046] Furthermore, in this embodiment, the second mask 200 has a third folded edge 210 and a fourth folded edge 220 that are adjacent to each other. The third folded edge 210 is located outside the first folded edge 110, and the fourth folded edge 220 is located outside the second folded edge 120, so that the second folded edge 120 limits the fourth folded edge 220, avoids the second mask 200 from slipping, and improves stability.

[0047] Optionally, in this embodiment, the photovoltaic inverter protective cover further includes a first connector, a second connector, and a third connector (not shown in the figure). The first connector is rotatably connected to the first support frame 300 and the first folded edge 110, the second connector is rotatably connected to the second support frame 400 and the first folded edge 110, and the third connector is rotatably connected to the fourth folded edge 220 and the second folded edge 120. The arrangement of the first, second, and third connectors enables the rotation of the first support frame 300, the second support frame 400, and the second cover 200, facilitating the unfolding and storage of the photovoltaic inverter protective cover.

[0048] For example, in this embodiment, the first connector, the second connector, and the third connector can all be configured as bolts or hinges. Furthermore, this embodiment does not limit the number of the first connector, the second connector, and the third connector.

[0049] like Figures 2-4As shown, the photovoltaic inverter protective cover in this embodiment has an unfolded state and a retracted state. In the unfolded state, the first support frame 300 rotates 90° around the first connector, the second support frame 400 rotates 90° around the second connector, and the second cover 200 rotates 90° around the third connector, so that the first support frame 300 and the second support frame 400 are both perpendicular to the first cover 100, and the first support frame 300 and the second support frame 400 are parallel to each other; the second cover 200 is perpendicular to the first cover 100, the first support frame 300, and the second support frame 400, thereby making the photovoltaic inverter protective cover form a housing chamber for accommodating the photovoltaic inverter.

[0050] In the folded state, the first support frame 300 rotates 90° in the opposite direction around the first connector, the second support frame 400 rotates 90° in the opposite direction around the second connector, and the second cover 200 rotates 90° in the opposite direction around the third connector, so that the first support frame 300 and the second support frame 400 are both in contact with the first cover 100, and the second cover 200 is in contact with the first support frame 300 and the second support frame 400. After folding, there is a gap between the first support frame 300 and the second support frame 400, which avoids interference and collision between the first support frame 300 and the second support frame 400, ensuring that the thickness of the first support frame 300 and the second support frame 400 is consistent, facilitating storage. The second cover 200 is located above the first support frame 300 and the second support frame 400, thus forming a three-layer folding structure, reducing volume, facilitating packaging and transportation, and saving transportation costs.

[0051] like Figure 2 As shown, in this embodiment, the first support frame 300 includes two first rods 320, and a second rod 330 is connected between one end of the two first rods 320. The second support frame 400 includes two third rods 410, and a fourth rod 420 is connected between one end of the two third rods 410. The other end of the first rod 320 is rotatably connected to the corresponding first folded edge 110 through a first connector, and the other end of the third rod 410 is rotatably connected to the corresponding first folded edge 110 through a second connector.

[0052] The arrangement of the first pole 320, the second pole 330, the third pole 410 and the fourth pole 420 simplifies the structure of the first support frame 300 and the second support frame 400, thereby making the photovoltaic inverter protective cover lighter and easier to disassemble and install.

[0053] like Figure 2 As shown, in this embodiment, reinforcing members 500 are provided between the first rod 320 and the second rod 330, and between the third rod 410 and the fourth rod 420, to improve strength, reduce the risk of deformation of the first support frame 300 and the second support frame 400, and improve stability and reliability.

[0054] Optionally, in this embodiment, both the first mask 100 and the second mask 200 are coated with a reflective coating to increase the reflectivity of sunlight, reduce the temperature of the photovoltaic inverter, improve the working efficiency of the photovoltaic inverter, and enable the photovoltaic inverter to maintain a stable power generation at a certain power level.

[0055] For example, the reflective coating can be set to white, and the reflective coating can be made of a corrosion-resistant material, so that the photovoltaic inverter protective cover can be used in high-salinity sea areas.

[0056] like Figures 2-3 As shown, in this embodiment, both the first support frame 300 and the second support frame 400 are provided with mounting holes 310. The mounting holes 310 are configured to lock with mounting components on the photovoltaic inverter, thereby achieving the purpose of hooking the photovoltaic inverter protective cover. Optionally, the mounting component can be a screw.

[0057] Specifically, first pre-lock the screws in their corresponding positions, then hook the photovoltaic inverter protective cover onto the screws from front to back and from top to bottom. Once the photovoltaic inverter protective cover is hooked onto the screws, it will not wobble. At this point, tighten the screws. To remove it, first loosen the screws to prevent them from falling off, then remove the photovoltaic inverter protective cover in the opposite direction. This method is convenient for single-person operation and saves labor costs.

[0058] Optionally, in this embodiment, the first support frame 300 and the second support frame 400 each have multiple mounting holes 310, and the multiple mounting holes 310 are equally spaced. This can improve the stability and reliability of the connection between the photovoltaic inverter protective cover and the photovoltaic inverter mounting components, and reduce or avoid the phenomenon of the photovoltaic inverter protective cover shaking.

[0059] Optionally, in this embodiment, both the first mask 100 and the second mask 200 are made of aluminum alloy, which reduces the weight of the photovoltaic inverter protective cover and facilitates single-person operation; both the first support frame 300 and the second support frame 400 are made of stainless steel, which improves strength, ensures the safety and stability of the photovoltaic inverter mounting components under stress, and extends the service life of the photovoltaic inverter protective cover.

[0060] For example, the photovoltaic inverter protective cover in this embodiment can be applied to photovoltaic inverters such as CPS SCH275KTL-DO / US-800, improving the universality and flexibility of the photovoltaic inverter protective cover and saving costs.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention.
