Slim junction box for photovoltaic applications

Tyco Electronics has launched the Solarlok, a small and slim junction box designed for use in photovoltaic (PV) industry applications.

The 15.5 x 52mm junction box distributes DC power to a solar panel in a compact design that offers the least amount of visibility on the back of a panel.

The product is TUV approved and meets stringent industry requirements, offering a 20-year product life performance.

Targeted applications include two-rail crystalline PV modules and two-rail thin-film PV modules, with a 3A current rating for thin-film applications and a 12A current rating for crystalline applications.

Tyco Electronics said the junction box reduces purchasing costs by offering a total assembly that includes solar-rated cables, which are available in various lengths to suit a variety of applications.

The assembly also includes IP67-rated Solarlok connectors, which produce an audible click to ensure proper installation and include a locking latch feature that meets code requirements.

One key feature of the junction box assembly includes a spring clamp for termination of the foil leads, which clamps to the contact rail inside the box for increased overall reliability and ease of termination.

This feature also eliminates the labour-intensive task of soldering.

Diodes are offered in multiple current ratings, ranging from 3A to 12A for optimised performance.

This feature allows users to select the diode requirement that best suits their application.

The Solarlok slim junction box does not require potting, eliminating the cost and mess of using potting material to seal the inside of a box from moisture.

In addition, the housing lid utilises two latches to secure attachment to the lower part of the box.

The connector interface is sealed to IP67 requirements.
