Description

Technical Field

[0001] The utility model relates to the technical field of energy storage device installation of an inverter, in particular to an energy storage device used for an inverter. Background Art

[0002] In the field of energy storage device installation technology for inverters, the installation and securing of energy storage devices are critical to ensuring stable operation and safe use of the inverter. Energy storage devices, such as battery banks or capacitor banks, typically need to be installed within a chassis to protect them from external environmental influences. However, existing energy storage device installation methods have several problems and shortcomings.

[0003] First, existing installation methods typically use screws. Not only is installation and removal cumbersome and time-consuming, but frequent installation and removal can also cause screws to strip or become damaged during inverter maintenance or upgrades, compromising the stability of the energy storage device. Furthermore, screw fixation can also lead to stress concentration from insufficient or overtightening, potentially shortening the lifespan of the energy storage device.

[0004] Secondly, the installation location and orientation of the energy storage device have a direct impact on the inverter's performance. An improper installation location can lead to poor heat dissipation, increasing the temperature of the energy storage device, thereby reducing its efficiency and lifespan. Furthermore, an incorrect installation orientation can affect the inverter's internal electrical connections and mechanical stability.

[0005] Furthermore, existing installation methods often lack effective positioning mechanisms to ensure the precise alignment of the energy storage device within the chassis. This can cause the energy storage device to shift due to vibration or impact during transportation and use, affecting the normal operation of the inverter and even posing a safety risk.

[0006] In summary, the existing inverter energy storage device installation technology has deficiencies in installation efficiency, stability and safety. Therefore, a new installation limit structure is needed to solve these problems. Utility Model Content
