Marine Grade. This is a very unusual charge controller in that it can charge a battery of a HIGHER voltage than the solar panel output that feeds it. In this way, you can charge a nominal 48v lithium battery pack to a precise 56.8v using a solar panel that puts out 33v at its maximum power point. This is the only device we've found that will do that.
We had these specially made by Genusun in their waterproof casing - fully potted and in a plastic enclosure. This will last forever in marine/boat applications as well as golf cart canopies or other outdoor in the weather applications.
This one is designed to charge 16 LiFePo4 cells to 56.8v using a Constant Current/Constant Voltage charge curve perfect for our LiFePo4 cells.
But it can do it from ANY of our flexible solar panels - a single panel.
Why? Put a single panel on the roof of your golf cart or the deck of your john boat and use this to charge a 48v battery pack at up to 8 amps. It could not be simpler. We haven't seen anything else out there like this "boost" charge controller device.
