So I have installed (2) 5250 CCA battery banks on my 22ft boat. One of the banks is strictly for the electric motor (docking and emergency use only). The other bank is for all other electrical appliances and acceressies (12v parallel circuit). I want to use wind, solar and water powered generators to recharge and maintain my battery banks. I have a continuous load of .5 kw with a max load of 1 kw/hr on the acceressies bank and a 1000 kw with a max of 4000 kw/hr load on the e-motor bank (12v). If I divide the power retrieval amongst the 3 charging systems (wind, solar and water) what are the sizes of the charging units needed to recharge and maintain both batter banks? What other components would be need to full fill this system?
