What do folks think of this? It seems like a good idea. From what I read online, desulphation is where the DC current from the controller is pulsed with a resonant frequency that dissolves the crystals that form on the battery and impede performance. I looked at my boat this weekend and I am going to mount the solar panel somewhere on the back and hook the charger into where my shore power charger output goes to my batteries in the aft port cockpit locker.
