This prevents overcharging and ensures a full charge, extending battery lifespan. DC Converter Mode Provides a stable, regulated output voltage, allowing the unit to function as a power supply for sensitive DC equipment. This protects devices from voltage fluctuations from the source battery. Engine Shutdown Detection Intelligently detects when the engine is running, ensuring the charger only draws power from the starter battery when the alternator is active, preventing discharge of the primary battery. Typical Applications Application Description Campervans & Motorhomes Charges leisure batteries from the vehicle's starter battery via the alternator, ensuring auxiliary power for appliances without draining the starting battery. Ideal for Euro 5/6 vehicles with smart alternators. Boats & Marine Vessels Maintains service batteries charged from the engine's starter battery, providing reliable power for navigation, lighting, and onboard electronics. Off-Grid Solar Systems Enables charging of a second 12V battery bank from a primary solar-charged battery, creating a robust dual-battery setup without needing a dedicated dual-battery solar charge controller. Mobile Workshops & Utility Vehicles Powers tools and equipment from an auxiliary battery, charged by the vehicle's electrical system, ensuring continuous operation on the go. Built-In Protection Functions The Victron Orion Smart 30A is equipped with comprehensive safety features for reliable and unattended operation. These include protection against overload, overheating (with power derating), short circuit, and reverse discharge of the battery. It also features an input voltage lock-out to prevent deep discharge of the source battery. The unit is designed to operate safely in various conditions, with an IP43 rating when installed correctly. Common Questions What types of batteries is this charger compatible with? The Victron Orion Smart 30A is compatible with all types of 12V lead acid batteries (including AGM, GEL, and flooded) and 12V lithium batteries. Can I use this charger with a smart alternator in my vehicle? Yes, this charger features an engine running detection mechanism, making it fully compatible with Euro 5 and Euro 6 smart alternators. It ensures proper charging even when the alternator's output voltage varies. How do I monitor and adjust the charger settings? The charger has built-in Bluetooth Smart connectivity. You can monitor live data, change charging algorithms, and adjust settings wirelessly using the free VictronConnect App on your smartphone or tablet. Can I connect multiple Orion Smart chargers in parallel? Yes, an unlimited number of Victron Orion Smart units can be connected in parallel to increase the total output current, allowing for faster charging of larger battery banks. Installation Notes Mount the unit vertically on a non-flammable surface with power terminals facing downwards for optimal cooling. Ensure a minimum clearance of 10 cm above and below the product for proper ventilation. Install close to the battery to minimise cable losses, but never directly above the battery to prevent damage from gassing. Use appropriate cable sizes (up to 16mm² / AWG6) and fuses as recommended in the manufacturer's manual. Refer to the detailed wiring diagrams and instructions in the Victron user manual for correct setup in either charger or power supply mode. Before You Buy Verify your source and target battery voltages are both 12V DC. This unit is not compatible with 24V systems. Confirm the maximum charging current of 30A is suitable for your battery bank size and charging requirements. Consider if you require an isolated or non-isolated DC-DC charger for your specific application. This model is non-isolated. Ensure you have a compatible smartphone or tablet for using the VictronConnect App for setup and monitoring. Review the full manufacturer's manual for detailed technical specifications and safety guidelines before installation. Always verify product specifications and compatibility with your existing system components before purchase and installation. This product is covered by a 5-year manufacturer warranty.
