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 systems!
