The Intelligent Dual-Charge Solution: Power When You Need It.

Combining alternator and solar charging into one smart, perfectly matched Victron system. Never worry about a flat house battery again.

Stop settling for a basic dual battery setup that only charges one way. The DC-DC / MPPT Bundle provides non-stop charging intelligence. Whether you're driving long distances or camped up for a week, your battery bank is consistently and safely charged, all monitored from one convenient app.

This bundle is the foundation of a modern, reliable off-grid power system.

Charging On The Move: Victron Orion-Tr DC-DC Charger

The vehicle’s alternator is your biggest power source. The Orion-Tr Smart ensures you harvest it safely and effectively.

• Smart 18A Output: Delivers a reliable, powerful 18 Amps (up to 220W) of charging current directly to your house battery while the engine runs.
• Isolated Design: Essential for modern vehicles and optimal compatibility, providing safety and peace of mind by completely separating the starter and house battery grounds.
• Smart Alternator Ready: Compatible with Euro 5/6 smart alternators that drop voltage, ensuring continuous charging unlike standard VSRs.

Charging At The Campsite: Victron SmartSolar MPPT 75/15

When the engine is off, the sun takes over. This intelligent controller is ready to connect up to a 200W solar array.

• Ultrafast MPPT Tracking: Converts solar energy into battery power up to 30% more efficiently than lesser PWM controllers, maximizing your daily solar harvest.
• 15A Capacity: Perfectly sized to handle the output of a standard touring solar panel (up to ~220W nominal panel power).
• BatterySafe Protection: Features intelligent load management and advanced charging algorithms for Lithium, AGM, Gel, and Lead Acid batteries.

The Seamless Victron Advantage

The real power of this bundle is in the integration.

• One App Control: Monitor input voltage, solar yield, charge stage, and history for both devices through the single VictronConnect App on your smartphone.
• Perfect Profile Match: Both chargers communicate the same optimal charging voltage profile to your house battery, ensuring faster, healthier charging cycles.
• Complete Independence: Enjoy the fastest recovery time whether you are driving (18A DC) or parked in the sun (15A Solar).
