Mission-Critical Reliability

Genasun controllers are deployed to the most remote locations on earth. They endure years at sea, harsh Antarctic winters, freezing conditions in the upper atmosphere on solar powered airplanes, and in a few off-the-map locations. Made in the USA, each controller is put through complete electrical testing to ensure reliability. If you need mission-critical power, this is your controller.

Get the Ceramic Edge. Electrolytic-Free with 10 Year Warranty

Genasun’s Ceramic controllers set a new benchmark for reliability. Traditional controllers have components filled with fluid electrolytes that boil off over time, causing system failure. Genasun Solid Ceramic controllers have no fluid. They don’t wear out in the heat. Backed by an industry leading 10 year warranty, these controllers take reliability to a new level.

High-Speed MPPT: Always on Target

Not all Maximum Power Point Tracking controllers were created equal. Most use a sweep and sleep method that scans the entire voltage range every 30-60 seconds. That's okay for a clear day, but traditional controllers are constantly off target during changing cloud conditions – exactly when power is scarce and is needed the most. Genasun controllers adapt to changing light conditions 20 times every second. They are always on target, capturing every bit of available sunshine. Simply put, other controllers can't keep up.

Advanced Lithium Charging Algorithms

Our Lithium charging algorithms draw from nine years of experience building Lithium battery packs for harsh environments. We've worked with every chemistry, and have tailored charge profiles to help you get more capacity and cycle life from your battery pack.


Small, critically efficient, and cost-effective, the GV-4 gets more from every panel.
