Lapp Group and FPE Fischer, a producer of aluminium junction boxes, have launched a new photovoltaic (PV) junction box with a modular design and unique accessibility to its electronics.
With the EPIC SOLAR RAZOR, the functional components in the junction box are accessed easily from the front side of the module. This makes it easy to reach and replace the functional components, such as surge protection, shutdown mechanism, performance monitor and performance optimisers. Furthermore, the design of the junction box allows the module to be upgraded with future technologies, such as MPPT (maximum power point tracking). An additional advantage is that the photovoltaic modules can be individually equipped with electronic components at the factory, by the dealer or even by the installer.
The flat junction box enables the PV module production steps to be optimised. The design of the box allows for simplified contracting through automatic welding. There is no curing time required for the adhesive elements, as the upper and lower elements are mechanically interlocked with one another.
The modular design of the aluminium junction box increases the flexibility of product variants for module manufacturers. It is made from highly durable aluminium material which reduces thermal load on the components and increases the service life compared to standard plastic junction boxes. At the same time, the risk of fire hazards is drastically reduced. The junction box is watertight in compliance with IP67 protection class. This prevents contact corrosion, resulting in constant performance at high level over the lifetime of the PV module and minimising the risk of hotspots and electric arcing.
The EPIC SOLAR RAZOR is preconfigured with the EPIC SOLAR 4 thin connectors. Due to its welded contacts, the contact resistance of the connector is very low.
