  • Key Features:
    Safe and Reliable Connection
    Features a snap-lock design that automatically locks upon insertion, effectively preventing loose connections or accidental disconnection, ensuring long-term stable system operation. It also includes an anti-mismating structure to prevent equipment damage caused by incorrect installation.
    Excellent Protection Performance
    Achieves an IP67 protection rating, effectively resisting rain, dust, moisture, and other environmental factors. Suitable for installation in outdoor, rooftop, and other complex climate conditions for PV systems.
    Weather- and Aging-Resistant Materials
    The housing is made of flame-retardant polymer material with excellent UV resistance and high/low temperature tolerance, capable of operating normally within a wide temperature range of -40°C to +90°C. It maintains stable performance even after prolonged outdoor exposure.
    Low Impedance, High Conductivity
    Internal contacts are made of tin-plated or silver-plated copper, offering low contact resistance and high conductive efficiency, which effectively reduces energy transmission losses and improves overall system power generation efficiency.
    Easy Installation
    The interface design complies with industry-standard specifications and is highly compatible with mainstream PV modules, cables, and combiner equipment on the market. No special tools are required for quick on-site installation, significantly reducing installation time.

    Application Scenarios:
    Suitable for residential rooftop PV systems, commercial and industrial distributed PV power stations, and large-scale ground-mounted PV power plants. It is an essential connecting component for module series/parallel connections and system wiring.
