Thank you so very much. We purchased a cannibalized DC Solar Trailer with (2) SMA 6048 inverters, Midnite Solar 250 Charge Controller and 10 panels. No generator or battery bank. This information will assist me in rebuilding the system with new 48v VRLA Battery bank for off grid power. I am trying to configure solar panels for these SMA and would like to know the maximum wattage/voltage/panel series for maximum power from the panels. Is there any further information or reference material for this subject? Thank you!
