[0002] A photovoltaic inverter is a device that converts the variable DC voltage generated by photovoltaic solar panels into AC power at mains frequency. This voltage can be fed back into the commercial power transmission system or used by off-grid power grids. It is a key component in balancing the system in a photovoltaic array system and can be used with conventional AC-powered equipment. It has special features that complement photovoltaic arrays, such as maximum power point tracking and islanding protection. Currently, photovoltaic inverters require a mounting structure to ensure stable installation during operation, allowing them to be used in combination with photovoltaic modules.

[0003] During the actual installation process of current photovoltaic inverters, the main body of the photovoltaic inverter is fixed, which makes it very troublesome to disassemble the photovoltaic inverter as a whole for maintenance. At the same time, due to the lack of shielding protection during installation, the service life of the photovoltaic inverter is easily reduced after long-term use. Utility Model Content

[0011] Preferably, the cooling airflow generated by the operation of the cooling fan inside the side mounting box passes through the distribution groove and then acts on the edge of the inverter body through the cooling groove.

[0016] 3. By arranging side mounting boxes, side interception nets, cooling fans, distribution air troughs and cooling troughs on both sides of the mounting box, cooling airflow is generated by the cooling fans during the operation of the inverter body.

A two-way threaded rod 7 is embedded in the inner side of the limit box 4 and is rotatably connected. Both sides of the two-way threaded rod 7 are connected to sliding blocks 6 by threads. One end of the two-way threaded rod 7 is connected to a rotating disk 8. The bottom of the sliding block 6 is connected to a limit plate 9. The two sliding blocks 6 are respectively connected to the thread segments of different rotation directions on both sides of the two-way threaded rod 7. The sliding blocks 6 slide along the inner wall of the limit box 4 and the guide groove 5, which makes it convenient to drive the two sliding blocks 6 to move through the two-way threaded rod 7, thereby driving the limit plates 9 to move toward each other, and the inner edge of the limit plate 9 is bonded with an anti-slip strip 10.

[0027] A T-shaped slot 11 is provided in the vertical direction inside the mounting vertical rod 2, and the back of the mounting box 1 slides along the T-shaped slot 11 by connecting the T-shaped seat 12. An edge adjustment slot 13 is provided on one side edge of the mounting vertical rod 2, and a locking bolt 14 is installed at the edge of the T-shaped seat 12 corresponding to the edge adjustment slot 13. The locking bolt 14 connecting the edge of the T-shaped seat 12 slides along the edge adjustment slot 13, and the T-shaped seat 12 is limitedly connected to the inner side of the mounting vertical rod 2 by the locking bolt 14, which is convenient for adjusting the installation position of the mounting box 1, thereby facilitating the adjustment of the installation height of the inverter body 3. Combined with the locking bolt 14, it is convenient to limit the use height of the inverter body 3, thereby ensuring the stability of the mounting box 1 after the position is adjusted.

[0028] Side mounting boxes 16 are fixedly installed on both side edges of the installation box 1, and side interception nets 17 are fixedly installed on the side ends of the side mounting boxes 16, and three groups of cooling fans 18 are equidistantly installed on the inner side of the side mounting boxes 16.

[0031] After the installation box 1 is installed, the inverter body 3 is installed in the installation box 1. The rotating disk 8 is rotated to drive the bidirectional threaded rod 7 to rotate. The rotation of the bidirectional threaded rod 7 drives the two sliding blocks 6 to move, thereby driving the limit plates 9 to move toward each other, so that the limit plates 9 can stably clamp and limit the inverter body 3 placed in the installation box 1, thereby facilitating the quick, convenient and stable installation of the inverter body 3 as a whole, ensuring the stability of the inverter body 3 during use.
