HUBER+SUHNER RADOX Solar Junction Boxes for module manufacturers are certified globally. HUBER+SUHNER offers a wide range of standard and custom-made connectivity systems for solar module manufacturers. They are a global manufacturer with a strong legacy of performance amongst other manufacturers of high-performance modules, especially with their models HA3 and RH3 junction boxes. Both systems stand out due to low forward voltage drop-through, excellent contacting (welding or soldering) of all components, connectors with lamella spring contacts, and the overall balance of the system. These boxes are characterized by minimal handling and assembly time, and are suitable for automation as well as for manual installation. An increased service life is ensured due to complete sealing and improved heat dissipation.
