Combiner Box

The next evolution of combiner boxes, optimizing both cost and layout
without sacrificing quality or performance.

Quality Performance

High Current
1500V Combiner Series

The Shoals High Current Combiner series is used to combine multiple strings per circuit up to a 60A fuse size. This means a more than 50% reduction in return cables over a traditional combiner box. Lab-proven under full load during static heating sequence testing with fuses installed, the High Current Combiner is designed for maximum durability and years of uninterrupted, real-world service. Field installation time has been slashed, space for cable terminations generously increased, and O&M torque points reduced by up to 41%.
