Decentralized Junction Box features 2-rail design.

Press Release Summary:




Featuring 18.5 mm profile, Decentralized Junction Box utilizes solderless Omega clip termination technique and is suitable for termination foils on crystalline PV panels. Design concept uses two 2-rail junction boxes separately located in corners of solar panels plus 1 small junction box in middle, enabling panel manufacturers to minimize use of jumper cable. Junction box meets IEC 61215 ed.2 (VDE V 0126-5) specifications.



Original Press Release:



TUV Approved Decentralized Junction Box Requires 50% Less Jumper Cable



With its new two-rail decentralized junction box, Tyco Electronics now offers a new way for locating junction boxes on a PV panel. Compared to the commonly used centralized junction boxes in the PV industry, the decentralized box requires 50% less jumper cable to connect to the next solar panel.

Product Features

o Low profile, only 18.5mm

o Separated diodes in separate boxes

o Proven solderless Omega clip termination technique

o 2-position style for layout flexibility

o Saves on length of the connecting cable

Applications

o For terminating the foils on crystalline PV panels

o Innovative layouts are possible due to separation of the diodes into independant housings

Intersolar -- Munich -- With its new two-rail decentralized junction box, Tyco Electronics now offers a new way for locating junction boxes on a PV panel. Compared to the commonly used centralized junction boxes in the PV industry, the decentralized box requires 50% less jumper cable to connect to the next solar panel, as the junction boxes are located in the corner of the panels.

The decentralized junction box uses fewer cross-connects than standard centralized boxes, offers excellent thermal management capabilities and enables engineers to design new innovative solar panel layouts. The general design concept uses two small two-rail junction boxes separately located in the corners of the solar panels plus one small junction box in the middle (compared with the common standard layout of one bigger four-rail junction box with three diodes in the centre of the panel). Through the decentralization of the two-rail junction boxes, panel manufacturers are able to use fewer and shorter cross connects (saving labour and costs) because every string is protected by one junction box with 1 diode.

With this new design concept it is easy to enlarge solar panel layouts by just adding a junction box in the centre to protect additional strings. No complicated routing is required. The low profile design (only 18.5mm height) of the two-rail decentralized junction box enables the device to be easily terminated with the slim line connector system by Tyco Electronics. The new decentralized junction box meets IEC 61215 ed.2 (VDE V 0126-5) specifications.
