LEADER® solar array junction box is used for crystalline silicon or thin-film solar photovoltaic modules. It consists of three parts: box body, solar PV cable, and solar connector. The product has passed the TUV/UL/IEC/CE standard certification, providing users with a safe, fast and reliable connectivity solution. The product design is based on the 25-year working life of photovoltaic power plants, with long-term stable electrical contact performance, and is an important component of photovoltaic modules.
  • Contact with drum-type crown spring, make electrical connection safety and fastness.
  • TUV/UL/IEC/CE certificated, compatible with 2000+ solar panel module and connectors.
  • Self-locking between the female and male connector, installation conveniently and reliably.
  • Ratchet mechanism desigh to lock the nut cover, avoid being loosened after long term using.
  • Contact resistance less than 0.35mΩ with Multi-Contact, less heating and low power consume.
  • Strong ageing resistance and UV resistance, suitable for use in multiple harsh outdoor environments.
It is suitable for various harsh outdoor environments such as deserts, lakes, seasides, and mountains (climate environments with high temperature, high humidity, and strong salt content). It is an important part of the solar system. Good connection quality ensures the long-term and safe operation of the photovoltaic system and effectively reduces the failure rate of the photovoltaic system and the later operating costs.
