“The SolarSpec range is further enhanced by the addition of panel-mount DC connectors for solar inverters, and includes junction boxes for silicon photovoltaic panels, DC connectors with crimp terminals for direct coupling to solar junction boxes, field installations, and photovoltaic grid cables, as well as DC wiring,” says Peter Commane, Molex Product Manager, adding: “Because the SolarSpec range is designed and manufactured in-house, we can guarantee high levels of quality and reliability at a competitive price. Customers will also benefit from Molex’s unique design advantages, including the ribbed molded surface and the lowest contact resistance in the industry.”.
The SolarSpec panel-mount DC connector features a contact resistance below 0.5 mW for exceptional efficiency. The contact can handle currents up to 30 A and accommodates 2.5 mm² (14 AWG) and 4.00 mm² to 6.00 mm² (12 to 10 AWG) wires to meet a wide range of customer requirements. Polarized openings in the panel help prevent connector rotation and cross-mounting of male and female connectors.
SolarSpec panel-mount DC connectors, known for their robustness and long lifespan, offer IP67 protection against dust and water ingress. The encapsulation is UV and ozone resistant. The touch-proof safety design protects installers and maintenance technicians from electric shock, even during coupling and uncoupling. The connectors feature unique ribs on the molded surface for a secure grip, especially when wearing gloves.
The solution developed by Molex, compliant with US NEC 2008 (690.33) and NFPA 70 codes, is an innovative interlocking mechanism that prevents accidental or unauthorized disconnection of the connector during field operation, ensuring a reliable connection and safe handling. To simplify panel mounting, the SolarSpec DC connector features a nut mechanism that is secured with a standard wrench to the solar inverter's panel shield. However, as an additional safety measure, a Molex on-site service tool is required to unlock the interlock during disconnection procedures.
