Description

Technical Field

[0001] The utility model relates to the field of grid-connected boxes, in particular to a distributed photovoltaic grid-connected box. Background Art

[0002] Distributed photovoltaic power generation refers to a distributed power generation system that uses photovoltaic modules to directly convert solar energy into electrical energy. It has a series of advantages such as proximity to users, low transmission costs, small impact on the power grid, flexible site selection, and a wide range of applications. It is one of the main photovoltaic power generation methods currently promoted. In the distributed power generation system, a distributed photovoltaic power generation grid-connected box is required to converge the current generated by each photovoltaic module so that the collected current can be connected to the power grid.

[0003] When the existing distributed photovoltaic power generation grid-connected boxes are used, the heat dissipation holes on the grid-connected boxes are generally of fixed size, and air intake and heat exhaust are carried out only through the heat dissipation holes, which makes it easy for dust to enter the grid-connected boxes. Although some of them are equipped with filters, after long-term use, especially in remote areas, the filters are blocked, which makes maintenance difficult and increases the inconvenience of maintenance.

[0004] In order to solve the above problems, this application proposes a distributed photovoltaic grid-connected box. Utility Model Content
