Heavy-duty bypass diode junction boxes featuring low contact resistance and high current capacities.
Our IP68 junction boxes provide reliable electrical termination and heat dissipation for split-cell and standard module layouts. Equipped with low-resistance Schottky bypass diodes, they prevent cell hotspot damage during shading. Every junction box is pre-assembled with solar cables and certified MC4-compatible locking connectors.
