Molex (NASDAQ: MOLX) has introduced the SolarSpecSmart Junction Box, designed to allow manufacturers of solar photovoltaic (PV) panels to more easily provide their products with module-embedded safety and monitoring functions, as well as convenient, safe and dependable connection capabilities.
The new system, which Molex is showcasing at the Solar Power International exhibition, October 18 - 20 (Booth #6854), features a series of interchangeable covers embedded with optimizing chipsets from SolarEdge Technologies, Inc., a provider end-to-end distributed solar power harvesting and PV monitoring platforms, to provide varying levels of electronic integration.

The SolarEdge power optimizers perform MPPT [maximum power point tracking] per individual panel while monitoring performance of each panel and communicating across existing power lines. Moreover, a fixed DC string voltage is maintained, allowing optimal efficiency of the SolarEdge PV inverter, which is tailor made to work with power optimizers. As a result, the SolarEdge system provides optimal power, while enabling flexible design and optimal roof utilization. Module-level and whole-system visibility enhance PV monitoring and maintenance capabilities. A proprietary SafeDCmechanism shuts down module voltage during installation, maintenance and firefighting for greater safety.
“The unique modular concept affords maximum flexibility and easy upgrade of PV-panel functionality, since the electronic PCB always resides in the removable Junction Box cover,” explains Peter Commane, product manager, Molex. “This smarter system not only facilitates lean solar manufacturing processes on a manual or automated assembly line, but also ensures easy access to key components should repair or replacement ever be required.”

Molex says the new smart junction box is based on the company's original two-part SolarSpecJunction Box, featuring a base attached directly to the solar PV panel and a removable cover assembly. Functionalities include system safety, shut-off and arc detection, security monitoring and theft protection, performance tracking on output levels and panel efficiencies, remote diagnostics and power optimization. The SolarSpec Junction Boxes can be supplied with optional Solder Charge technology for use in conjunction with high-speed assembly processes that provide consistent quality for every termination. A locking mechanism requiring a specialized tool to release secures the top cover to the base, providing total protection against accidental contact with live parts.
