Description

A steep slope inverter installation device

Technical Field

The utility model relates to the technical field of rooftop photovoltaic inverters, in particular to a steep slope inverter installation device.

Background Art

In the construction and development of the photovoltaic industry, with the reduction of available land resources for photovoltaics, the proportion of rooftop distributed photovoltaic power station projects is increasing. The steel-structured industrial plant with a large area of colored steel tile roof and high electricity consumption users undoubtedly meets the construction requirements of rooftop distributed photovoltaic projects. The main function of the solar inverter is to convert direct current into alternating current. As photovoltaic power generation enters the home, the size of the solar inverter is gradually reduced, and its installation method has also changed from the previous ground-mounted placement to wall-mounted as the installation location on the steep slope of the roof changes.

Since the inverter is small in size, it is very inconvenient to drill holes in the inverter casing. Therefore, the prior art usually uses an installation box as a container to fix the inverter on the steep slope of the roof by bolt installation. However, the existing installation box has a simple structure. Not only is the built-in inverter easily exposed to direct sunlight and rain, but the design of the input and output lines is unreasonable. The wiring harness is easily disturbed by the external environment and short-circuited. Finally, the heat dissipation method of the existing installation box is also relatively simple, which is difficult to meet the heat dissipation requirements of the inverter.

Therefore, in view of this, the existing structural deficiencies are studied and improved, and a steep slope inverter installation device is proposed.
