REDARC Alpha 50A DCDC Charger

REDARC BCDC Alpha50 – 50A DC to DC Charger

Maximum power, maximum confidence.
The REDARC BCDC Alpha50 delivers a massive 50A of fast, efficient charging to keep even the largest dual-battery setups powered — no matter how demanding your gear is. Whether you’re running fridges, lights, inverters, comms, or full touring systems, the Alpha50 ensures your start and auxiliary batteries stay topped up using power from your vehicle’s alternator or solar.

With Green Power Priority™, solar is automatically prioritised to reduce alternator load, minimise fuel consumption, and maximise free energy from the sun.

Instant Insight

Stay fully informed with real-time monitoring and control via Bluetooth and the RedVision smartphone app. View charge status instantly, customise input current limits, and protect your electrical system by tailoring performance to match your vehicle and battery setup.

Start Battery Recovery

A flat start battery won’t stop your adventure. The BCDC Alpha50 can recover a flat start battery with a single button press, getting your vehicle ready to start again quickly and safely. Once your auxiliary battery is full, the Alpha50 automatically diverts excess solar power to top up your start battery — so no energy goes to waste.

Simplified Installation

With a pushbutton setup, screw terminals, and no soldering required, the Alpha50 is designed to make installation as easy as possible. Paired with REDARC’s range of wiring kits and mounting brackets, it’s simple to achieve a clean, professional install.

Built Tough for Australia

Designed, tested, and manufactured in Australia, the Alpha50 is engineered for harsh touring conditions. With IP67/69K dust and water protection, it’s built to outlast and outperform, even in extreme heat, corrugations, and wet environments.
