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. The typical contact resistance is ≤0.25 mΩ, ensuring minimal power loss and efficient energy transfer. The cable size accommodated is 6mm²/10AWG, providing ample capacity for current flow. The NSPV brand design incorporates a three-part layout: negative, middle, and positive, facilitating easy and secure connections.
