The key to getting the most out of your solar panel investment is choosing the right marine MPPT charge controllers.  OceanPlanet Energy supplies the following brands which represent the highest quality with many options to choose from.

Genasun 2013 Logo

Using engineering developed for MIT’s solar race car, Genasun marine MPPT charge controllers feature the highest performance in both shaded and full sun applications. Genasun MPPT controllers scan and adjust 20 times per second to optimize output 1,200 times faster than standard MPPT controllers, ensuring maximum energy collection. With 99% peak efficiency they are the best option for small arrays and can actually reduce overall cost per watt of solar power.
