About Genasun

MIT Solar Car


Solar power with smarts.

Founded in 2005 by a group of MIT engineers, Genasun sets the bar for mission-critical solar charge controllers and lithium battery systems. With über high-end, off-grid solar charge components and advanced lithium battery systems, Genasun’s robust product line has been deployed—and trusted—by scientific and military communities in all corners of the world, guaranteeing power where and when you need it most.

No condition too harsh

Though our controllers were born at MIT and made in the USA, they usually end up living pretty far from home. Designed and tested to withstand the most intense conditions on earth, Genasun controllers can brave years traversing the roughest seas, endure harsh Antarctic winters, power freezing upper-atmosphere flights on solar planes, and deliver steady, reliable power to the most remote locations on earth. It’s all because of our industry-leading technology, created to deliver solar power you can count on.

Designed to Survive.

Alex MeVay, Genasun’s founder, was sailing the Yucatan in 2003 when his power went out. An industry leader’s PWM solar charge controller had failed somewhere between Guadeloupe and Boston, leaving him stalled in the open ocean to fend for himself. MeVay disassembled the controller to find poorly designed electronics and more cut corners than he could count. And though he had spares available, he was unnerved having bet his life on a shoddy solar component.

After returning to the USA, MeVay joined the MIT solar car team, where he spent the next three years refining leading-edge design of solar charge controllers and lithium batteries, and designing what would later be Genasun’s first MPPT controller. And thus, a new day in solar power began.

A Few Things We Live By At Genasun.

Heat leads to failure. And we tolerate neither.

Cyclic heating stresses electronics, ultimately leading to system failure. While most companies use large heat sinks to get rid of heat, Genasun designed more efficient controllers that simply create less.

Ceramic is one tough S.O.B.

Genasun’s ceramic controllers set a new benchmark for reliability. Traditional controllers have components filled with fluid electrolytes that boil off over time, causing systems to overheat and fail. Using industry first ceramic technology, Genasun offers the first solar charge controller designed to last longer than your panel.

No fans. No relays.

Fans get clogged with dust and dirt, and relays eventually stop switching. Using sophisticated electrical design and software, we’ve engineered out all moving components so that your Genasun controller won’t ever leave you out in the cold.
