Re: 48v battery bank charged by 12 v charge controller
Welcome to the forum.
In my opinion this falls under the "not going to work" category. The (-) on the Sunsavers would be common to each battery, whereas the 48 Volt bank the second battery's (-) is connected to the first battery's (+) - a dead short across one output. You'd have to break the 48 Volt series connections to charge the batteries individually, and that's not very practical is it?
