Morningstar SunSaver Duo Advantages
SunSaver Duo Advantages:
Morningstar’s SunSaver Duo is an advanced PWM two battery controller for RV’s, caravans,
boats and cottages. Rated for 25 amps at 12 volts DC, 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. 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.
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.
