This process includes: Bulk Stage: Delivers maximum current to rapidly charge the battery until it reaches approximately 70% of its full capacity. Absorption Stage: Maintains a constant voltage for a timed period (typically 4 hours) to fully charge the battery and balance cells. Float Stage: Reduces the voltage to a lower level to maintain the battery at full charge, compensating for self-discharge. An internal temperature sensor provides automatic compensation of the charge voltage, optimising charging performance and extending battery lifespan, especially in varying ambient temperatures. A DIP switch allows selection of specific charge/float voltages tailored for Flooded Lead-acid, Gel, or AGM battery types. Typical Applications Application Description Marine & Boating Provides reliable charging for multiple battery banks on yachts, motorboats, and other vessels. Off-Grid Systems Ideal for maintaining battery health in remote power setups, cabins, or holiday homes. RV & Camper Vans Ensures auxiliary batteries are consistently charged for leisure and travel. Diesel Electric Systems Can function as a DC-DC converter, accepting 90-400V DC input. Built-In Protection Functions The Victron Centaur Charger is designed with robust protection features for reliable operation and longevity. It includes automatic reduction of output current under extreme environmental conditions, thanks to integrated temperature sensors. Circuit boards are protected with an acrylic coating for maximum corrosion resistance, while the epoxy powder-coated aluminium case with drip shield and stainless steel fixings ensures durability against heat, humidity, and salt air. The charger is compliant with international safety standards including CE for Europe and UL for the United States. Common Questions What battery types are compatible with this charger? The Victron Centaur Charger 24V/40A is compatible with Flooded Lead-acid, Gel, and AGM batteries. A DIP switch allows you to select the optimal charge/float voltages for your specific battery type. Can this charger be used worldwide?

How many battery banks can it charge simultaneously? This model has three isolated charge outputs, allowing it to simultaneously charge up to three separate battery banks. Each output is capable of supplying the full rated current. Does it have protection against harsh environments? Absolutely. The Centaur charger features an epoxy powder-coated aluminium case, drip shield, stainless steel fixings, and acrylic-coated circuit boards to resist heat, humidity, and salt air, making it highly durable for adverse environments. Installation Notes Professional installation by a qualified electrician or marine technician is highly recommended to ensure safety and optimal performance. Ensure the charger is installed in a dry, well-ventilated area, preferably in a vertical position for optimum cooling. Verify that the available power source matches the product's input voltage and frequency specifications. Use appropriate cable sizes for battery connections to minimise losses and ensure safe operation. Refer to the manufacturer's manual for detailed cable specifications. Proper grounding and wiring are essential. Anchor all cables and wiring properly to relieve them from strain and twisting. Before You Buy Battery Voltage: Confirm your battery bank requires a 24V charger. Battery Capacity: Ensure your battery bank capacity falls within the recommended 160-400 Ah range for optimal charging. Battery Type: Identify your battery chemistry (Flooded, Gel, or AGM) to ensure compatibility and correct DIP switch settings. Installation Environment: Consider the operating environment to ensure the IP20 rating and robust construction are suitable for your needs. Documentation: Always consult the official Victron Energy Centaur Charger manual for complete installation instructions and safety guidelines. Please verify all specifications and compatibility requirements with your system before purchase. Product specifications are subject to change by the manufacturer. Typically backed by a manufacturer's warranty.
