The Morningstar Sunsaver Duo regulator will charge 2 seperate battery banks at the same time. This can be split as a 50/50 charge option or 90/10, depending on your requirements. If one battery bank becomes fully charged the regulator will automatically divert all current produced by the solar panel to the second battery bank.

This regulator comes complete with a display that can be remotely mounted and gives information on charge current and battery voltage.
