Reliability. Safety. Convenience.

We at AMtec Solar are confident you’ll agree that our Prominence line of DC Combiner Boxes are a synthesis of all three. After years of manufacturing combiner  boxes for some of the biggest names in the solar industry, we’ve taken our expertise and applied it to product available to everyone. 


There is a lot more to a combiner box than many inexperienced installers might understand. This piece of your installation can be a strong bridge to the long term success of your project or, a weak link to numerous service issues if quality is sacrificed.

AMtec Solar delivers quality and price. And, our specialty is adapting to your project with enclosure, grounding and connecting lug options rather than making you adapt to our product line! 


AMtec Solar produces the combiner box that can go the distance.
