Features
Morningstar SunSaver Duo Controller. 25 amps / 12 volts
The Morningstar SunSaver Duo is a two battery bank solar controller with optional remote meter for RV’s, caravans and boats.
- Two Battery Charging – Solar charge current is shared between two batteries based on a user selectable priority. When one battery is fully charged, all of the charge current flows to the other battery.
- Highly Reliable – Epoxy encapsulation protects the controller against dust and high humidity. Extensive electronic protections, including short circuit, over current and reverse polarity, ensure that the controller will not be damaged by wiring mistakes or overloads.
- User Adjustable – Control parameters may be adjusted using the DIP switch on the controller. Further customizing is enabled by connecting to a personal computer and using Morningstar’s PC software.
