Reduce installation steps for solar farms with TE Connectivity’s SOLARLOK SLK 2.0 DC plug and splice connectors 


All-in-one product offers fast, reliable photovoltaic cable connection to the solar panel


A new plug and splice connector from TE Connectivity (TE), a world leader in connectivity and sensors, helps to improve the efficiency and profitability of solar farms. The demand for solar power continues to grow, and so does the need for more robust systems that deliver increased power and efficiency. When system size grows, complexity does too, as well as costs for installation, operation and maintenance. The solar energy market needs cost-effective and reliable connections that can be installed quickly, easily and accurately.


An installation time of 30 seconds is now possible for a mated pair with the SOLARLOK SLK 2.0 DC plug & splice connectors. The product range is 80% faster to install when compared to market-standard PV connectors with multiple components and crimp contacts. The SOLARLOK SLK 2.0 connects the PV cable to the solar panel in field installations with extended voltage ratings of 1500V TUV/IEC and UL. The design integrates Insulation Displacement Contact (IDC) technology, removing the need for cable stripping and avoiding potential damage to the cable. The single-piece product allows for fewer installation steps and no special tools required, resulting in reliable product performance and reduced labor and maintenance costs.


These new products are IEC 62852 (TUV) and UL 6703 approved, with a gel filling that ensures IPx8 water ingress protection. They are resistant to submersion in water to a maximum depth of 1m for up to 24 hours.


  • SLK 2.0 plug connectors incorporate the SOLARLOK 1500V PV4-S interface, to meet the latest solar PV needs, and are available in both male and female versions, enabling them to mate with SOLARLOK PV4-S and PV4-PM DC connectors. They are also range taking, so one connector fits conductors from 2.5 to 6 mm² (10 to 14 AWG).


  • SLK 2.0 splices are provided as a single piece, reducing the risk of incomplete connectors. This accelerates the termination process, with no loose parts to handle and no custom tools required. They are especially suitable for repairs, enabling quick and easy lengthening of cables, or to provide a solution for cables which have been attacked by animals or have mechanical insulation issues. SLK 2.0 splices are also equipped with a dovetail feature, enabling them to be stacked side by side.


“Our new SOLARLOK SLK 2.0 DC plug and splice connectors will be a game-changer for the industry. The integrated IDC technology removes the need for cable stripping, so the installer can simply plug in the cable and snap on the button to terminate, for increased speed, efficiency and lifetime connection,” says TE Product Manager Frank Rosenkranz.
