Important note

Ideal for battery banks over 200Ah. Compatible with 12V and 24V vehicle systems, including those with smart alternators. Tested for extreme Australian conditions.

We accept
For 12V vehicles with a 12V auxiliary battery bank. Ideal for 4WDs, utes, vans, camper trailers and caravans. Our workshop hardwires an ignition trigger to the charger on smart-alternator vehicles and multi-charger setups (for example a BCDC in the vehicle plus another in the caravan). For a 24V system, use the Redarc BCDC2420 instead.

40A DC-DC + MPPT SOLAR

Dual input — alternator and MPPT solar controller in one in-cabin unit.

GREEN POWER PRIORITY

Solar takes precedence over the alternator when the panels are producing — saves fuel.

LITHIUM AND AGM READY

Six charge profiles cover AGM, gel, calcium, standard lead-acid, LiFePO4 and custom.

HARDWIRED IGNITION TRIGGER

Our workshop hardwires an ignition trigger on smart-alternator vehicles and multi-charger setups so all chargers only run when the vehicle is running.

2 YEAR REDARC WARRANTY

Backed by 2 years direct from Redarc. Repair or replacement in accordance with Redarc's warranty policy.

The REDARC BCDC1240D Classic is a 12V 40A DC-DC battery charger for a 12V auxiliary battery bank, with a built-in MPPT solar regulator. Charges from your vehicle's alternator, solar panels, or both at once — Green Power Priority uses solar first to reduce alternator load and save fuel.

Six charge profiles cover AGM, gel, calcium, standard lead-acid, LiFePO4 lithium and custom setups. Fanless, in-cabin design.

Smart alternator vehicles and multi-charger setups. Our workshop always hardwires an ignition trigger to the charger on late-model vehicles with stop-start or variable-voltage smart alternators, and on any build with more than one BCDC (for example a charger in the vehicle plus a second charger in the caravan) so all chargers only run when the vehicle is running. Ask us if you're unsure whether your vehicle needs this.

Output is 12V. The 9-32V input range means it will run on a 12V or 24V vehicle, but the output is always 12V. For a 24V system, use the Redarc BCDC2420 instead.

Sized for battery banks around 120Ah to 320Ah. Rated for in-cabin installation only, not engine-bay use.

Everything this install needs

0 of 0 in the box

Engine-bay rated for under-bonnet installation. Comes with mounting points. Must be fused correctly (60A input/output). Professional installation recommended.

For 12V vehicles with a 12V auxiliary battery bank. Ideal for 4WDs, utes, vans, camper trailers and caravans. Our workshop hardwires an ignition trigger to the charger on smart-alternator vehicles and multi-charger setups (for example a BCDC in the vehicle plus another in the caravan). For a 24V system, use the Redarc BCDC2420 instead.

Q: What's the difference between DC-DC and MPPT solar input?
A: This charger has both. The DC-DC side runs from your vehicle alternator when driving. The MPPT solar side pulls from a fixed or portable panel when parked. Green Power Priority runs the solar side first when both are connected.

Q: What chemistries does it support?
A: AGM, gel, calcium, standard lead-acid, LiFePO4 lithium, and a custom profile. Set the profile at install.

Q: Where does it mount?
A: In-cabin — under a seat, in a service body, or in the caravan bulkhead. Not rated for engine bay use.

Q: Does it work with smart alternators?
A: Yes. Our workshop always hardwires an ignition trigger to the charger on smart-alternator vehicles and on any build with more than one BCDC (for example a charger in the vehicle plus a second charger in the caravan), so all chargers only run when the vehicle is running.

Q: What size solar panel can I connect?
A: Up to 25V open-circuit voltage. Panel size in watts depends on your bank size and daily use — we usually pair a 40A charger with around 300W of solar.

Q: How long is the warranty?
A: 2 years, direct from Redarc.
