| ARRAY ADAPTORS | Why do I need an array adaptor?
If you have what some manufactures call an MC4 compatitable connector, you will need an array adaptor. A connection between an MC4 compatible connector and an MC4 connector is not UL certified and could possibly fail. Cross-mating any connector, regardless of the brands involved, is not a UL approved connection. It does not matter that both connectors may have independent UL approvals, as they were tested to their own, specific individual tolerances and specifications. After time, connections fail due to cross mating issues. The issue is that the metallurgical chemistry of the contacts are going to be different unless they are from the same manufacturer. Over time, the difference in chemical composition causes oxidation and other issues that can lead to temperature rise and other problems. |
