Morningstar Sun Saver Duo - No Display
Solar Charge Controller
Morningstar’s SunSaver Duo is an advanced PWM two battery controller
for RV’s, caravans, boats and cottages. This product will charge two
separate and isolated batteries at the same time, such as a "house" and
an engine battery, based on user selectable priorities.
The SunSaver Duo employs Morningstar’s legendary
SunSaver controller technology, whose long-term track
record for high reliability and improved battery charging is
well-recognized in the solar industry. This controller also includes a
backlit remote meter which may be mounted in or on a wall, and displays
digital and pictorial status
information about the solar power system.
The SunSaver Duo is epoxy encapsulated for environmental protection, is user adjustable via DIP switch or
connection to a personal computer, and has an optional remote temperature sensor.
It works great with just one battery, too!
If there is only one battery, the SunSave Duo
sends up to all 25A to the single battery with no detrimental effects.
The second battery can be added at a later time, or not at all. The
meter shows dashes for battery 2 as it is not in use.
At 25A with a remote meter, it is actually a really great value for a
high current 12V digital controller with remote meter for single battery
- Two Battery Charging
Solar charge current is shared between the two batteries
based on a user selectable priority. When one battery is fully
charged, all of the charge current flows to the other battery.
- Provides Useful Information
The remote meter and LED’s display system status data and
any system errors. Custom icons and back lighting make the
meter easy to read and understand.
- Lower Cost
Two battery charging eliminates the added cost of two
separate solar charging systems and the need for isolation
between the batteries.
- Easy to Install
The controller is installed near the batteries using the clearly
labeled large wire terminals. The remote meter may be
mounted in the wall or on the wall using the included frame.
Also includes the meter wiring with RJ-11 connector.
- Longer Battery Life
Four stage series PWM pulse charging and temperature
compensation increases the useful life of the batteries.
- Extensive Electronic Protections
The controller will not be damaged by wiring mistakes
during installation. There are no fuses to replace, and the
controller will automatically re-set after a wiring mistake.
- Highly Reliable
Epoxy encapsulation protects the controller against dust
and high humidity. Efficient electronics and a conservative
thermal design allow the controller to operate reliably
at high temperatures. Five year warranty and estimated
15 year life.
Includes controller, meter and 10 m (33 ft.) of meter wire.
