The photovoltaic connector is the key part connecting the components, combiner box, controller and inverter in the photovoltaic power generation system. In the photovoltaic power station, the electric energy of a large number of components must be gathered together and enter the inverter, which must rely on cables and connectors. The photovoltaic system is exposed to the wind, sun and extreme temperature changes for a long time, which requires that the connector must be able to adapt to these harsh environments.
