Molex has further expanded its range of ‘SolarSpec’ products with the development of pin (male) and socket (female) panel-mount DC connectors. SolarSpec panel-mount DC connectors, with internal locking and touch-proof design for superior safety, feature an innovative nut mechanism for simple assembly to the panel and a durable connection for cable attachment to solar inverters. The products will be showcased at the Solar Power International at booth 6854.

Problem

The NEC 2008 (690.33) and NFPA 70 US code-compliant solution developed by Molex is an interlocking mechanism that prevents accidental and unauthorized decoupling of the connector during service in the field and provides for reliable connection and safe handling.

Solution

SolarSpec panel-mount DC connectors, with internal locking and touch-proof design offer contact resistance of below 0.5 milliohms. The contact can handle as much as 30.0A and accommodates 2.50mm2 and 4.00 to 6.00mm2 (14 AWG and 12 to 10 AWG) cable to meet a wide range of customer requirements. Polarized panel cut-outs help prevent rotation of the connectors and ensure no cross-assembly of male and female connectors on the panel. The connectors are IP67-sealed to protect against the ingress of dust and water, and the housing body is resistant to UV and ozone damage. The touch-proof safety design protects installers and maintenance engineers from electrical current even during mating and decoupling operations. The connectors feature exclusive molded surface ribs to allow secure gripping, especially while wearing work gloves. For ease of assembly, a simple nut mechanism on the SolarSpec panel-mount DC connector is tightened using a standard wrench, to secure onto the bulkhead of the inverter panel. For added security, a Molex field service tool is required to disengage the latch when unplugging.

Applications

Panel-mount DC connectors.

Platform

The panel-mount DC connector for solar inverters complements the SolarSpec portfolio, which now encompasses the junction box for silicon photovoltaic panels, crimp terminal DC connectors for direct attachment to solar junction boxes, field installation and photovoltaic grid wiring, and DC cable assemblies.

Availability

October 2011 onwards.

The utility-scale PV market is poised for exponential growth and yet the industry still has many fundamental opportunities to improve on standards and best practice. Tracker shade loss has been one of those topics that deserve more attention, but has been typically handled by derate factors rather than trying to accurately forecast the loss over the life of the system. Join Nextracker’s subject matter experts, Aron Dobos and Neelesh Umachandran, and Rounak Kharait, director of solar energy assessments at DNV, for a webinar about why shade modeling matters and recommendations on what the solar industry should do about it.

Join us to hear directly from the CTOs and heads-of-research from the top-20 cell/wafer producers to the PV industry today. The event will focus on predicting the key metrics underpinning the next big shift to n-type with answers to the key questions: When will the transition to n-type happen? Which companies will be first to 10 GW capacity and production? Who will be the key equipment suppliers for the new production lines? Which n-type process flow/architecture will emerge as the front-runner? What will polysilicon purity and wafer thickness levels look like for optimized n-type manufacturing? What will the upstream poly/wafer supply-chain look like in 5 years from now?
