I have a question. I would like to set up a house battery bank, with shore charging, alt charging, and say a wind generator. Can all these sources just be attached to the battery directly or must there be a gizmo in line which only allows current to flow to the battery so they can't power each other? I also would like to set a start battery seperate form the house battery, and have the alt firt top the start battery then flow over to the house batteries. What type of controller would I need.Any simple wireing diagrams would also be appreciatedDave
