SPI 2016 - Fronius and Maxim Integrated Collaborate on Next-Generation Solar Optimization

Inverter manufacturer Fronius and semiconductor company Maxim Integrated Products, Inc. have expanded their collaboration to provide new levels of DC optimization to solar solutions.

Portage, IN, September 2016 - Inverter manufacturer Fronius and semiconductor company Maxim Integrated Products, Inc. have expanded their collaboration to provide new levels of DC optimization to solar solutions.


Multiple orientations, module mismatch, degradation or soiling are reasons why solar installers choose module level power electronics (MLPE) for their installations. Unfortunately, traditional optimizers or micro-inverters have significant downsides. Not only are they costly, but also time-consuming to install and difficult to service while far from performing efficiently. Therefore, it's time for the next step in DC optimization.

Through close collaboration, Fronius SnapINverters and Maxim solar cell-string optimizers are now able to deliver new levels of seamless integration and high performance. Fronius has a long history of working successfully with Maxim and has committed significant engineering resources into the collaboration.

"Our engineers conducted long-term testing and focused on both stability and performance of systems with Maxim optimizers", says Tristan Kreager, Director of Solar Energy at Fronius USA. "Fronius' collaboration with Maxim demonstrates both companies' commitment to providing flexible system design and ease of installation with this new generation of solar optimization."

The Maxim chip-based cell-string optimizer replaces the traditional bypass diode and equips each solar module with 3 optimizers, each independently performing maximum power point tracking (MPPT) - resulting in the best-in-class solution for shade mitigation, string mismatch, and soiling. Furthermore, the solution offers unparalleled design flexibility. It accommodates multiple orientations, different modules, and shading or asymmetric designs with up to 20% difference in string length. The tolerance for shading allows for the tightest of row spacing in commercial rooftop systems without any limitations.

"As a leading inverter manufacturer and trusted brand, Fronius is a great collaboration partner for Maxim. Together we can provide the market with a reliable, cost-effective, and high-performing solution for solar optimization," says Seth Kahn, Executive Director, Solar Products, Maxim Integrated.

Since off-the-shelf Fronius SnapINverters (Galvo, Primo and Symo lines) work seamlessly with Maxim cell-string optimizers, the installation process is identical to any standard system. There are no additional hardware components to install, no extra settings to make and no communication hassles on the roof. The deeply embedded optimizer eliminates the need for any extra installation step, which aligns with Fronius' strong focus on best user-experience.

Modules with Maxim's optimizer technology are available now and work seamlessly with off-the-shelf Fronius SnapINverters, which are fully available on the market. Visit Fronius at this year's Solar Power International in Las Vegas (booth #1521) to learn more about solar cell-string optimization and Fronius' solar solutions.

LG Solar Unveils NeON R with Enhanced Aesthetics and Energy Savings

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
