BlueSolar PWM-DUO Charge Controller

www.victronenergy.com
Features
- PWM controller
- Charges two separate batteries. For example the starter battery and the service battery of a boat or
mobile home
- Programmable charge current ratio (standard setting: equal current to both batteries)
- Charge voltage settings for three battery types (Gel, AGM and Flooded)
- Internal temperature sensor and optional remote temperature sensor
- Protected against over current
- Protected against short circuit
- Protected against reverse polarity connection of the solar panels and/or battery
