An MC4 Y branch connector is a type of electrical connector used in photovoltaic (PV) systems to connect multiple solar panels together in parallel. The "Y" shape of the connector allows for one positive and one negative cable from one panel to be connected to the positive and negative terminals of two other panels, respectively. This allows for the electrical current from multiple panels to be combined, increasing the overall power output of the PV system. MC4 refers to a specific standard for the connectors and their mating interfaces, which is established by the manufacturer Multi-Contact AG.
