I am wireing the alternator for a 48 volt system. What would be a great set up for getting 110 into the house? How many bateries, and how they hook up? Are they 12 volt bateries hooked up somehow to get 48, or are they 48 volt to start with? How many should I buy? whats a good inverter to get and so on. I am starting from scratch so help me make a good system.
