Description

This invention relates to an electrical connector and an inverter connected to a solar cell module including the same. A solar cell module may include a solar cell panel containing solar cells, and a wiring box containing components, circuits, etc., connected to the solar cell panel. After installing solar modules, their operating status can only be checked using a separate communication device, such as a web interface or application. Because it is difficult for solar modules to recognize their own operating status, there is a problem with effectively managing them. To address these issues, a solar cell module equipped with structures and components that allow for monitoring of its operating status has been proposed. For example, a structure has been proposed in which a light source capable of displaying the operating status of the solar cell module is included, and the operating status of the solar cell module can be confirmed by the presence or absence of operation of the light source (i.e., presence or absence of flickering, interval, etc.). To address this, a structure was proposed in which the lens is positioned on the side wall of the wiring box, and one side of the guide tube and guide tube, into which the light source is inserted, is fixed to the wiring component, while the other side is connected to the lens. Thus, a light source, lens, guide tube, and guide tube guide are necessary to check the operating status of the solar cell module. Furthermore, an O-ring is required between the lens and the case for waterproofing. As the number of components within the device for checking the operating status of the solar cell module increases, so does the cost. Additionally, there is the problem of decreased productivity as the manufacturing process of the device becomes more complex.
