4mm2 mc4 extension cable Solar DC Cable solar pv cable

introduction

Solar panel extension cable is used for safe and simple series or parallel connecting solar PV modules, inverters, or solar power plant systems. Certification with TUV/UL/IEC/CE standards, suitable for 2.5-10 mm2 photovoltaic solar cables. The connector design is based on the 25-year working lifetime of the photovoltaic power station and has long-term stable electrical contact performance.

Contact with drum-type crown spring, make electrical connection safety and fastness.
TUV/UL/IEC/CE certificated, compatible with 2000+ popular solar module 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 environment 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.
