Description

Technical Field

[0002] The primary function of a photovoltaic inverter is to convert the direct current (DC) generated by solar panels into alternating current (AC) for household appliances. The AC output requires separate wiring by the user to connect to the home power grid or grid-connected system. Inverters commonly use output terminal wiring, and the terminal designs vary between manufacturers. Most inverters have their AC output located at the bottom of the unit. However, to increase power density and reduce size, current inverters have overloaded the bottom terminal area, making it unsuitable for current needs. Currently, some side terminals use large secondary cavities for wiring and protection, resulting in larger size, higher material costs, and increased dimensions and weight. Utility Model Content
