On the 25 ft sailboat I take offshore I normally have a single 40w solar panel to keep the two 12V Optimus batteries charged. When I go offshore I add two more for a total of three 40w panels. I also have a really vintage propeller driven 12v generator that is basically your old 57' Chevy's generator with a rope and a 2hp Johnson propeller on a stainless shaft. I use it rarely, but it is there if I need it. Actually works really well but produces a good deal of drag. Puts out about 10 amps at 6 kn. If I put the power lead from the generator to the PV connections along with the solar panels will the controller handle it?
I have researched this and cannot find a clear answer.
