Application of Y-type solar connector in photovoltaic project

       The Y-type DC connector is a special connector for photovoltaic power stations. It is mainly used for the circuit connection between outdoor solar panels and inverters or combiner boxes. Its function is to connect two parallel photovoltaic strings into one circuit. Its characteristics mainly include anti-ultraviolet, abrasion resistance, aging resistance, and outdoor working life of up to 25 years.

       The MPPT of the mainstream high-power string inverters on the market is two-channel DC input. Two strings of photovoltaic modules are connected in parallel through the Y-type terminal through the Y-type terminal, and connected to one of the MPPT string input ports, thereby reducing the number of sets. The number of cables from the string end to the inverter achieves cost savings. For the 2-channel string/MPPT string inverter, The specific schematic diagram of the application of Y terminal is as follows:
