MikeF Posted June 29, 2023 Share Posted June 29, 2023 In general having a single battery bank in a motorhome is the prefered system. I presume you also have seperate controllers for each panel. Also its not clear if either of both batteries have additional charging from 230v AC hook up or from engine alternator via a relay or battery to battery charger. The capacity of each battery would be useful infomation. If the batteries are of similar age and type, having a single 12v system with the batteries connected in parallel, feeding everything the 'caravan' area would be the prefered arrangement. The two solar controllers Icould be connected to the battery bank with no problems. My thinking is the fridge has a higher priority than the TV, so having as much solar power and battery capacity for keeping food/ drinks cold, would seem the ideal set up. Further information would help formulating advice, Age, type and Ah capacity of the two batteries? Model of solar controller and charge voltage settings, if known? Solar panel type, flexible or rigid framed? Alternator charging if fitted? Mains hook up charging if fitted, ( and which or both batteries are charged)? Any commercial electrical control unit fitted, example, Sargent or CBE? Mike Link to comment Share on other sites More sharing options...
