Based on our own experience the Xantrex Freedom SW Stacking Cable is a huge disappointment.As a hesitant buyer, we were hoping that this wiring product will improve power stability in our industrial facility. unfortunately, the faulty design made it worse. Its totally incompatible with our other power equipment. The cons outweigh the pros of this product. Trust us and avoid this frustration in your installation process. Industrial and scientific buyers, steer clear of this ineffective waste of money..
