PV connectors play a crucial role in the wiring of solar arrays. As designed and if correctly installed, they provide a high-voltage, high-current, low-resistance DC connection in a housing that is water-tight, temperature-resilient, UV and wire-pull-resistive over the 25-year-plus life of the solar installation. In addition, their snap- together connectionRead More
