Photovoltaic connectors are used in many parts of the photovoltaic system. The photovoltaic connector is the key part that connects the components, controller and inverter in the photovoltaic power generation system. In a PV plant, it is necessary to rely on cables and connectors to bring the electrical energy of a number of components together and into the inverter. High-quality photovoltaic connectors must meet the following conditions: waterproof, high temperature, UV resistance, low resistance, and long warranty period.
