I am setting up a new electrical system on my Catalina 27. In addition to my outboard, which puts out 12amps from it's alternator, I want to add a wind vane and solar panel to the charging system. I have a 255aH AGM battery.The wind vane and OB both have regulators, and I can get one for the solar panel if needed.Is there a regulator/charger/combiner that can combine the charges from my OB, solar panels, and wind vane to give a 3 stage charge to my battery?
