Morningstar's SunSaver Duo is an advanced, PWM, two-battery controller which is suitable for caravans, boats and small buildings not connected to the National Grid. PWM controllers maintain a higher state of charge in the battery bank than old-fashioned on-off regulators.
The SunSaver Duo will charge two separate, isolated battery banks at the same time using selectable priorities. You can also adjust the controller's settings either manually or via a connection to a personal computer.
The Sunsaver Duo includes a back-lit, remote meter which may be mounted on a wall and displays digital and pictorial information about the status of your solar power system. There is an optional remote temperature sensor and a number of electronic protection mechanisms to protect against short circuits, lightning and overloading.
With an anodized aluminum case, corrosion resistant terminals, and epoxy encapsulation, the SunSaver Duo can be mounted virtually anywhere. In the unlikely event that a fault occurs with the Sunsaver Duo, it carries a five-year manufacturer's warranty.
For greater charging efficiency, particularly when battery temperature varies by more than 5C throughout the day/year, add a Morningstar remote temperature sensor.
To connect up your system, we recommend FlexSol outdoor-rated solar cable. We can also make up complete cables to your specification - see the cables and connectors page.
Suitable for 12V systems only.
