Victron Orion Smart 15A 12V DC to 24V DC automatic multi-stage intelligent

The Victron Orion Smart 15A 12V to 24V DC-to-DC Battery Charger is an intelligent multi-stage battery charger designed to automatically charge a 24V battery or battery bank from a 12V source battery or bank. Its compact and lightweight design allows seamless integration into existing systems, making it ideal for vehicles, boats, and solar setups where a secondary battery needs to be charged efficiently and safely.

Function

This smart battery-to-battery charger draws energy from a 12V source battery—such as an engine starter battery consistently charged by an alternator or a primary battery charged by solar or mains—to charge a 24V target battery. The Orion Smart operates at a maximum current of 15A, using a fully automatic multi-stage charging algorithm with built-in overcharge protection.

It is perfect for upgrading a single battery system to a dual battery system without requiring a replacement of your existing solar charge controller. The unit can also operate in DC conversion mode, delivering a stable output voltage with minimal electrical noise, suitable for sensitive DC equipment.

Key Features

- Bluetooth connectivity: Monitor and configure the charging process remotely using the VictronConnect app, without needing physical access to the unit.

- Safe unattended charging: Offers complete protection against overload, overheating, overvoltage, short circuit, and reverse current discharge, allowing continuous connection to the source battery.

- Continued charging during battery/load use: Maintains full charging performance while energy is being drawn from the target battery. Connected 24V loads remain protected from overvoltage and fluctuations.

- Compatible with alternative charging sources: Thanks to the integrated suppression filter, the target battery can also be charged from solar panels, generators, or other DC sources while remaining connected.

- Remote on/off control: The unit can be manually switched on or off via a wired switch, external relay, or VictronConnect app, enabling automatic control by a Battery Management System if required.

- Vehicle battery optimisation: Efficiently charges 24V batteries in vehicles with smart alternators or Euro 6+ emission systems, providing full power even on short journeys while protecting against overcharging.

- System upgrade potential: Two units can be connected in parallel to increase charging capacity, suitable for large battery systems or high-demand 24V appliances.

Additional Features

- LED indicators show charging stage and Bluetooth connectivity status.

- Lightweight and compact design allows easy retrofit and integration.

- Multi-stage automatic charging ensures safe, efficient operation for both lead-acid and lithium 24V batteries.

Compatibility

This DC-to-DC battery charger is compatible with 12V source batteries and 24V target batteries, including lead-acid (AGM, Gel, Flooded) and lithium chemistries. It cannot be used to charge 12V batteries from a 24V battery bank .
