Description

Technical Field

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

[0002] An inverter is a converter that converts DC power (battery, storage bottle) into constant frequency and voltage or frequency and voltage regulated AC power (usually 220V, 50Hz sine wave). It consists of an inverter bridge, control logic and filter circuit. For example, energy storage inverters have more and more functional requirements and more and more complex internal structures, and their size and weight are also increasing. The height of inverters on the market now ranges from 300mm to 800mm, and the weight ranges from more than ten kilograms to more than forty kilograms. For example, photovoltaic inverters are usually installed on photovoltaic panel brackets. Because they cannot be installed close to the ground, at least two people are required to operate together during installation. One person lifts the inverter and the other installs it on the photovoltaic panel bracket. The installation is very laborious.

[0003] For this purpose, we design an inverter installation auxiliary device here. Utility Model Content
