NSPV Solar Panel NEHP01 Junction Box Series
- Medium Panels: Two-part Junction Box
- Large Panels: Three-part Junction Box
- Type 1: 22A (with 30A diode)
- Type 2: 35A (with 50A diode)
Product Introduction
The NSPV brand Solar PV panel NEHP01 junction box is a top-tier component designed for reliable and efficient solar installations. With an IP68 rating, it offers exceptional protection against water and dust, ensuring durability in various environmental conditions. The junction box comes in two types: Type 1 supports a rated current of 22A (with a 30A diode), while Type 2 handles up to 35A (with a 50A diode), both rated for DC 1500V. Its typical contact resistance is ≤0.25 mΩ, minimizing power loss and enhancing system efficiency.
Constructed from high-quality PPE/PA materials, the NEHP01 junction box exhibits excellent UV and water resistance, extending its lifespan and reducing maintenance costs. Its three-part NSPV brand design (negative, middle, positive) simplifies installation and ensures secure connections. Certified by TUV and compliant with IEC standards, it guarantees safety and reliability. By choosing the NEHP01 junction box, users can enjoy cost savings through reduced maintenance and enhanced system performance, all while benefiting from its superior safety features.
Product Specifications
The NEHP01 junction box comes in two types, catering to different current requirements. Type 1 is rated for a current of 22A and includes a diode capable of handling up to 30A, while Type 2 is designed for a higher current of 35A, with a diode rated at 50A. Both types support a rated voltage of DC 1500V, making them compatible with a wide range of solar panel configurations.
