The REDARC BCDC Alpha 50R charger is the new benchmark for 4x4 enthusiasts, van lifers, and those embarking on long expeditions. This 50A DC-DC charger is designed to guarantee a reliable power supply, no matter how remote your campsite. It allows you to charge your auxiliary batteries with remarkable efficiency via the vehicle's alternator or solar panels. Thanks to its robust construction and advanced technology, it withstands the harshest environments, withstanding operating temperatures from -20°C to 60°C.

Green Power Priority technology for maximum solar yield

One of the major innovations of this model is the Green Power Priority function. This intelligent system automatically prioritizes solar energy whenever it is available. By favoring photovoltaic panels (up to 1000W of power), the Alpha 50R reduces the load on your alternator, resulting in significant fuel savings on long journeys. Once your service battery is fully charged, the surplus solar energy is automatically redirected to maintain the charge of your starter battery, thus preventing any unpleasant surprises at the time of departure.

RedVision connectivity and intelligent app-based management

The REDARC Alpha 50R is more than just a charger; it's the brain of your electrical system. Using the RedVision app on your smartphone, you can monitor the charging status, incoming power, and remaining range in real time. If your starter battery is too low, this charger has a backup function that can recharge it in just 15 minutes via the interface or the app. It's fully compatible with all batteries on the market, including Lithium LiFePO4 batteries, while also protecting the sensitive alternators of hybrid and modern vehicles.

What is the maximum solar power accepted by the Alpha 50R?

This charger accepts solar power up to 1000W. It is equipped with a high-performance MPPT regulator that manages a solar input voltage range of 9V to 48V. Note that the solar input voltage must never exceed 48V for charging to occur.

Is it compatible with Lithium (LiFePO4) batteries?

Absolutely. The REDARC Alpha 50R's intelligent charging algorithm is pre-configured for all common battery types: Lithium LiFePO4, AGM, Gel, Calcium, and Lead-Acid. The RedVision app lets you select the exact charging profile to maximize your battery's lifespan.

Can I install this charger on a hybrid vehicle?

Yes, the BCDC Alpha 50R was specifically designed to be compatible with smart alternators and the electrical systems of hybrid vehicles. It limits the load on the alternator to prevent overheating or damage in modern small vehicles.

What happens if my starter battery is completely dead?

The Alpha 50R includes a "Recovery" function. By pressing a button or via the app, the system transfers power from your auxiliary (or solar) battery to the starter battery. In just 15 minutes, you recover enough power to start the engine.
