Description

Technical Field

[0001] This utility model relates to the field of photovoltaic inverter installation technology, specifically a photovoltaic inverter suspension device. Background Technology

[0002] A photovoltaic (PV) inverter is a power electronic device that converts direct current (DC) generated by solar panels into alternating current (AC). A PV inverter mainly consists of two parts: a power conversion circuit and a control circuit. The power conversion circuit typically employs a full-bridge or half-bridge topology, using high-frequency switching devices (such as IGBTs) to convert DC to high-frequency AC. Then, a filter circuit converts the high-frequency AC to mains frequency AC. The control circuit is responsible for controlling the power conversion circuit, including implementing the MPPT algorithm, grid synchronization control, and protection functions.

[0003] Photovoltaic inverter suspension devices typically consist of metal brackets and fasteners, allowing the inverter to be fixed to a wall. They are suitable for indoor or outdoor locations with adequate wall space, such as small inverters in distributed photovoltaic power generation systems installed on the exterior walls of buildings. By suspending the inverter, better air circulation is achieved, which helps dissipate the heat generated during operation. Good heat dissipation conditions can reduce the inverter's operating temperature, improve its efficiency and reliability, and extend the equipment's lifespan.

[0004] Regarding the existing related technologies, the inventor believes that there are the following drawbacks: In the existing technology, photovoltaic inverters are generally fixed to the wall with bolts during installation. When the inverter needs to be repaired, the engineer needs to use tools to unscrew the bolts in order to remove the inverter for repair, which is time-consuming and labor-intensive. Utility Model Content

[0005] To address the problem that engineers currently need to use tools to unscrew bolts in order to remove the inverter for maintenance, which is time-consuming and labor-intensive, this utility model provides a photovoltaic inverter suspension device.

[0006] This utility model is achieved using the following technical solution: A photovoltaic inverter suspension device includes a fixed plate and an inverter body.
