[0021] The utility model embodiment provides a string inverter, such as Figure 1-4 As shown, the string inverter includes: an inverter body 1 arranged at the bottom of the photovoltaic panel; two clamping rods 2, the two clamping rods 2 are respectively fixed on both sides of the inverter body 1; two support plates 3, the two support plates 3 are respectively sleeved on the two clamping rods 2; two adjustment plates 4, the two adjustment plates 4 are respectively fixed on the two support plates 3; a base 8, the base 8 is slidably installed at the bottom of the two adjustment plates 4; two drive assemblies, the two drive assemblies are both arranged on the top of the base 8, and the drive assemblies are used to adjust the position of the inverter body 1.

[0022] In this embodiment, the inverter body 1 is arranged at the bottom of the photovoltaic panel, which effectively prevents direct sunlight and is beneficial to the heat dissipation and service life extension of the inverter body 1. The clamping rod 2 cooperates with the support plate 3 to stabilize the inverter body 1 and facilitate disassembly. The base 8 serves as the basis of the entire inverter installation structure to ensure that the inverter is stably installed under the photovoltaic panel. The main function of the drive component is to adjust the position of the inverter body 1. Through the drive component, the inverter body 1 can be transferred from the bottom of the photovoltaic panel, thereby facilitating subsequent maintenance.

[0023] In a further preferred embodiment of the utility model, the driving assembly includes a threaded rod 5, two fixed plates 6 and a motor 7, the two fixed plates 6 are fixedly mounted on the top of the base 8, the threaded rod 5 is rotatably mounted between the two fixed plates 6, the motor 7 is fixedly mounted on the fixed plates 6, and the output shaft of the motor 7 is fixedly connected to the threaded rod 5.

[0024] In this embodiment, the two fixed plates 6 serve as the basic supporting structure of the entire drive assembly. The fixed plates 6 ensure the stability and firmness of the drive assembly. The threaded rod 5 is a key part of the drive assembly. It can rotate under the drive of the motor 7, thereby realizing the adjustment of the position of the inverter body 1. When the motor 7 is started, its output shaft will drive the threaded rod 5 to rotate, thereby driving the inverter body 1 to adjust its position.

[0025] In a further preferred embodiment of the utility model, a plurality of U-shaped cards 9 are installed on the inverter body 1, and a plastic plate 10 is clamped in each of the U-shaped cards 9. Pull rings 11 are fixed on the tops of the plurality of plastic plates 10. A plurality of fixing nuts 12 for stabilizing the wires 13 are provided at the bottom of the inverter body 1, and the number of the fixing nuts 12 is consistent with the number of the plastic plates 10, and the wires 13 are connected to the photovoltaic panels.

[0026] In this embodiment, the U-shaped structure of the U-shaped card 9 can effectively fix the plastic plate 10 to prevent it from shifting or falling off. When the plastic plate 10 needs to be removed or installed, the user only needs to use the pull ring 11 to easily operate without using additional tools, thereby improving the convenience of operation. The wire 13 is fixed by the fixing nut 12 to ensure the neatness and safety of the wire 13. The connection between the wire 13 and the photovoltaic panel ensures that the inverter body 1 can normally receive the electric energy generated by the photovoltaic panel and convert it into usable power output.

The wire 13 can be further stabilized by the adjustment rod 14. This arrangement effectively avoids confusion and entanglement of the wire 13, and improves the neatness and aesthetics of the entire installation structure. At the same time, since the wire 13 is effectively supported and fixed, its safety and stability during operation are also guaranteed.

[0029] In a further preferred embodiment of the utility model, a fixing rod 17 is provided on the adjusting rod 14 and the supporting rod 15, two electric telescopic rods 16 are fixed on the two fixing rods 17, and a plurality of electric telescopic rods 16 are respectively fixed on the adjusting rod 14 and the supporting rod 15.

[0030] In this embodiment, the position of the fixing rod 17 can be adjusted by adjusting the extension length of the output rod of the electric telescopic rod 16. The fixing rod 17 cooperates with the adjusting rod 14 and the supporting rod 15 to stabilize the wire 13 and prevent the wire 13 from falling off.

[0031] In a further preferred embodiment of the utility model, a silicone card block 18 is fixedly installed on one side of the two adjusting rods 14 close to each other, and the multiple silicone card blocks 18 can respectively contact the multiple wires 13, and the support rod 15 and any two of the fixed plates 6 are located on the same X-axis line.

[0032] In this embodiment, the material of the silicone card blocks 18 is soft and has a certain degree of elasticity, so that they can be in close contact with the wires 13 without causing damage to the wires 13. This contact method not only ensures the stability of the wires 13, but also effectively prevents the wires 13 from shaking and falling off during operation. By clamping the wires 13 in the silicone card blocks 18, the confusion and entanglement of the wires 13 can be effectively avoided, thereby improving the aesthetics of the entire installation structure.

[0033] In a further preferred embodiment of the utility model, the two motors 7 are both covered with a waterproof protective shell, the base 8 is provided with a plurality of openings through which fixing bolts can pass, and the plurality of plastic plates 10 are provided with font grooves.

[0034] In this embodiment, the design of the waterproof protective shell can effectively prevent the motor 7 from being corroded by moisture when working in a humid environment, thereby ensuring the stable operation of the motor 7 and extending the service life. At the same time, the waterproof protective shell also increases the safety of the motor 7 and avoids problems such as electrical failures or short circuits caused by moisture. The open design allows the base 8 to be firmly installed under the photovoltaic panel or other suitable positions through fixing bolts. The font grooves can clearly display relevant information of the plastic plate 10, such as the number, function or warning word of the wire 13, so that the user can more conveniently identify and operate during use and maintenance.

[0035] In summary, compared with the related art, the present device can adjust the position of the inverter body 1 by setting a driving component. The inverter body 1 can be moved away from the bottom of the photovoltaic panel to expose the inverter body 1, thereby facilitating maintenance. The electric wire 13 can be clamped and limited by setting an adjusting rod 14, a supporting rod 15, an electric telescopic rod 16 and a fixing rod 17, thereby increasing the stability of the electric wire 13 of sufficient length required for the transfer of the inverter body 1.
