Product: Solar PV Plug DC Blocking Diode Connector Size: 15A Quantity: 5Pcs Description A durable DC blocking diode connector designed for parallel connection of solar panels. This 15A version provides a secure crimped contact, a waterproof sealing ring, and insulation engineered for outdoor durability. Quick to assemble and compatible with a range of PV cable sizes, it helps prevent backflow and simplifies panel wiring. Key benefits Reliable electrical contact: Crimpstyle pin makes a rock solid connection that holds under heavy load when properly installed. Protection against moisture and contamination: Integrated waterproof ring seals the connection to reduce corrosion risk and block dust and water ingress. Outdoorready insulation: Insulation material is formulated for aging resistance and UV endurance to support long outdoor service life. Fast installation and maintenance: Simple plug assembly and removal without special tools speeds installation and field work. Broad cable compatibility: Works with PV cables of various insulation diameters to match common solar cable specifications. Specifications and function Function: DC blocking diode connector for preventing reverse current when connecting solar panels in parallel. Rated size: 15A model. Compatible family includes 10A, 15A, 20A, and 30A variants for different system needs. Connection type: Crimp pin to wire for a solid mechanical and electrical joint. Sealing: Waterproof ring on the connector housing to protect the contact area. Insulation: UV resistant and aging resistant material for extended outdoor exposure. Quantity: 5 pieces per package. Typical applications Rooftop solar arrays: Use these connectors when tying multiple panels in parallel to prevent reverse current and simplify wiring. Off grid systems and small installations: Ideal for cabin, boat, or caravan solar setups where reliable blocking diodes and quick assembly are needed. Repairs and upgrades: worn connectors on garden lighting arrays, charge systems, or small commercial PV strings to restore reliable performance. Installation notes Crimp the pin securely to the PV cable conductor using an appropriate crimp tool sized for the wire gauge. Ensure the waterproof ring and connector housing are fully seated to maintain the seal. Select the correct current rating for your system. This listing is for the 15A connector, available alongside 10A, 20A, and 30A variants for different load requirements. This connector provides a practical, easy to install solution for preventing reverse current in parallel solar arrays while offering durable outdoor performance and broad cable compatibility.
