I have got 12 , 12v lithium batteries, 12 335v solar panels and a Schneider 4840. How should I setup my Outback charger controller for it to be the most efficient?
Not sure what 'most efficient' means exactly but looks like a 48v system so I would be charging at close to 56.8 volts with absorption time at a short 15 minutes. Then float about 53.2 volts. No equalization. No temperature compensation.
Anything special to consider? Be sure each battery is fully charged at 12v so they are in equilibrium before being connected together.
