Balmar Duo Charge DDC-12/24 Regulator

The Digital Duo Charge (DDC-12/24) 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-12/24 automatically engages, providing up to 30A charge current to the starting battery. When no charge source is present, the DDC-12/24 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.

Digital Duo Charge: DDC-12/24
Multi Bank Charging

• The DDC is a Solid-State Battery Combiner
