SunSaver
Since the introduction in 1996, more than 1.5 million SunSaver Controllers have set the standard for reliability and performance in demanding oilfield and mining installations in nearly 90 countries around the globe. Today, SunSaver is the world’s leading small solar controller for industrial and consumer markets, proven in mission critical applications where failure is simply not an option.
This third generation SunSaver brings over two decades of advances in software and electronics to the same rugged, hardened design that made the original famous. Own both a legend and the latest in a single product.
