What is a Photovoltaic Connector?
A photovoltaic (PV) connector is a device used to establish a safe and reliable electrical connection between photovoltaic (PV) panels. They also connect PV panels to other components of a PV system, such as inverters, charge controllers, and batteries. PV connectors ensure efficient energy transfer and minimize any power loss in the system.
Classification of Photovoltaic Connectors
DC Connectors
DC connectors are used to connect the DC output terminals of PV modules to a DC power supply system. Generally, DC connectors can be classified into several types, including copper-body DC connectors, PPO (Polypropylene) DC connectors, and PC (Polycarbonate) DC connectors. Copper-body DC connectors are the most common type, typically used in high-power applications. They are relatively expensive but have a long service life and wide applicability. PPO and PC DC connectors, due to their materials, have good high-temperature resistance and corrosion resistance.
AC Connectors
AC connectors are used to connect the AC output terminals of a power generation device to the AC input terminals of a power distribution network. AC connectors include not only plugs but also sockets, connecting wires, and covers. AC connectors are classified in the same way as DC connectors, commonly including copper-body AC connectors, PPO AC connectors, and PC AC connectors. Their advantages and disadvantages are similar to those of DC connectors.
MC4 Connector
The MC4 connector is one of the most commonly used connectors in polycrystalline silicon solar panel modules. Due to its easy installation, good waterproof performance, high temperature resistance, and corrosion resistance, it is widely used in photovoltaic power plants. The MC4 connector consists of three parts: the connector body, the inner core, and the rivet. The connector body material includes PPO, PA66, etc.
