Digital Duo Charge: DDC-12/24
For Multi Bank Charging
The Digital Duo Charge (“DDC”) provides a “hands off” solution for charging two battery banks without the use of problematic isolators or manual battery switches.
During charging the DDC-12/24 monitors voltage at the house battery. When voltage exceeds the set minimum (typically 13.2V in a 12V system and 26.4V in a 24V system) the DDC automatically engages, providing up to 30A charge current to the starting battery. When no charge source is present, the DDC separates the batteries so the starting battery won’t be accidentally discharged into the house battery. An optional solenoid control enables higher start battery charging output when required.
