In this project EFI worked with the most innovative power conversion company in the solar industry. Our client envisioned changing the way power is delivered from solar modules to the grid. This new technology would revolutionize solar power management by converting power at or near the module allowing the array of panels to operate athigher efficiencies. This new design would also record and transmit performance data for each module allowing customers to monitor and manage their solar power system. The challenge faced by our clients’ engineering team became how to protect the complex electronics and EMU components required by this design from out-door operating environments typical of module installations. The client needed the involvement of an expert encapsulation team at the outset of product design to ensure environmental conditions would not impede the performance of this new innovative design.


EFI Polymers worked with our client from the ground up. We were able to call upon our years of experience, and proven background in developing insulation systems for other smart grid applications requiring rugged environmental performance. We provided weekly design consulting, and developed a system that would meet all the engineering requirements including:
Thermal conductivity sufficient to maintain critical operating temperature limits
Corrosion protection to block moisture vapor and protect sensitive electronic components
CTE protection for surface mount components during extreme thermal cycling -65C to 105C.
Compatibility with components and design so that maximum operating efficiencies are achieved and sustain for long life.


EFI worked step-by-step with the manufacturing process design and implementation teams around the world to ensure on time production start-ups at multiple manufacturing sites. Initial test results proved our product was spot on. The product performed flawlessly throughout thermal cycling. From the first steps of product design to the final highout-put, six sigma manufacturing process, our team was there to support our clients vision and meet their project goals.


Today, EFI continues to bring improvements to our client’s next generation of power management products. We understand that getting to market is only the first step in our clients winning company strategy. Product evolution and cost reductions are key components to long term market domination. To help our client reach their financial goals we made significant cost reductions in our encapsulation system that helped our client capture a 50% overall cost reduction, enabling our client to leave their competitors in the dust.
