SunExTM Power Maximizer
Maximizes PV system efficiency at the lowest cost
Power optimization technology
The SunEx power maximizer solves real-world problems facing PV arrays. SunEx power optimization was originally created to minimize environmental (shading, clouds, dirt, debris, bird droppings) and system mismatch (string-to-string imbalance, different orientations, tilts, panel aging) that degrade system performance and efficiency. Through this technological innovation, system current and voltage mismatch are corrected and increased performance efficiencies are achieved, resulting in maximum PV system efficiency and lowest cost per KWh. The power maximizer monitors and maximizes the energy harvest of each individual PV module through advanced algorithms combined with leading-edge mixed signal technology, recouping up to 75% of the lost energy due to mismatches.
Smart panel integration
The power maximizer is designed to be integrated into solar PV panels, creating “smart panels”. These smart panels incorporate award-winning SunEx power maximizers directly into solar modules, creating a cost- effective distributed electronics solution to underperformance issues that reduce the solar array output. Using proven advanced algorithms and mixed-signal technology, smart panels provide power optimization at the modular level to maximize array performance and reliability while minimizing balance of systems costs and boosting return on investment.
The power maximizer establishes a new level of performance while maintaining ease of system design and installation. It includes enhanced features such as 350W module power handling capability, industry-best efficiency (99.5% peak), tri-mode buck-boost architecture for highest system efficiency. Panel mode operation continually monitors for the presence of mismatch. If no mismatch is found, the power maximizer will pass through the power of the module instead of operating on it, ensuring maximum possible efficiency is attained.
