The Morningstar SunSaver Duo Charge Controller, 12 volt 25 amps with Remote Meter
Morningstar’s SunSaver Duo is an advanced Pulse Width Modulated (PWM) two battery controller for RV’s, caravans, boats and cottages.
This technology provides:
- Two Battery Charging
- Backlit Remote Meter
- Easy Installation
- Lower Cost
- Optional Remote Battery Temperature Sensor
Features:
- Solar charge current is shared between the two batteries.
- Two battery charging eliminates the added cost of two separate solar charging systems.
- Remote meter may be mounted in or on a wall and displays digital and pictorial status information.
- Includes controller, meter and 10 m (33 ft.) of meter wire.
