Genasun 

Genasun was founded by a group of engineers from MIT and all the charge controllers are equipped with the Maximum Power Point Tracking (MPPT) technology to reach a conversion efficiency greater than 99%. Not all MPPTs are the same, Genasun technology tracks the MPP 15 times per second to capture each single Watt from the panel. Genasun are the lighter, smaller, and most efficient solar charge controllers in the market. Buck or Boost technology, they are designed for lithium and lead-acid batteries and tested for the marine industry.
