Charge your auxiliary battery from the alternator and the sun at the same time, on the move.
The REDARC BCDC1212S is a 12A dual-input DC-DC charger built for 12V touring rigs, camper trailers, and 4WDs running a second battery. It combines vehicle charging with a built-in MPPT solar regulator, so a single unit handles both your alternator and a roof or portable panel without a separate solar controller. It is a sensible match for smaller auxiliary banks where a 12A charge rate keeps up without overkill.
- Dual input: draws from the vehicle's alternator and solar, with green power priority given to free solar when available.
- Integrated MPPT solar regulator harvests more from your panel than a basic PWM controller.
- Multi-stage charging with selectable profiles suits AGM, lead-acid, and other common chemistries.
At 12A this is aimed at modest battery banks; larger banks that need faster recovery are better served by the 25A or 40A models. See more options in DC-DC chargers or browse the full REDARC range.
