What is the Victron Orion-Tr Smart 24/12-30A?
The Victron Orion-Tr Smart 24/12-30A (ORI241236140) is a step-down DC-DC converter (also known as a reducer or step-down booster) that transforms the 24 V from your vehicle or boat's main battery into a stabilised 12 V charging current, with an intelligent three-stage algorithm (bulk – absorption – float).
It is the professional solution for trucks, motorhomes with 24V electrical systems, 24-volt boats, industrial vehicles and military 4×4s that need to power 12 V equipment (radios, GPS, fridges, auxiliary lighting) or charge a 12 V auxiliary battery while keeping all Victron's protections and intelligent charging features.

Applications of the Orion-Tr Smart 24/12-30A
- Trucks and heavy vehicles: powering 12 V auxiliary equipment (radio, sat-nav, cab fridge, auxiliary lighting) from the 24 V main system.
- Large motorhomes with 24V systems: charging a dedicated 12 V auxiliary battery for appliances or lower-voltage equipment.
- Professional marine: larger boats with a 24 V main system that need a 12 V secondary circuit for navigation electronics, sonar or lighting.
- Industrial and military 4×4 vehicles: reliable, stabilised power for 12 V communications, instrumentation or lighting equipment.
- Caravans and motorhomes with 24V solar: use solar energy stored in the 24 V battery bank to keep a dedicated 12 V auxiliary battery charged.
Key features of the Orion-Tr Smart 24/12-30A
- Smart 24 V → 12 V step-down converter with output adjustable between 10 V and 15 V (configurable via Bluetooth)
- Built-in Bluetooth Smart: monitoring, configuration and firmware updates from the VictronConnect app (iOS and Android)
- Adaptive 3-stage algorithm: bulk – absorption – float, with absorption times automatically adjusted based on depth of discharge
- Buck-boost function: keeps output voltage stable across the full 16 – 35 V input range, compensating for alternator voltage drops
- Compatible with Euro 5 and Euro 6 smart alternators: engine-running detection
- 30 A continuous / 45 A peak (10 s) at 12 V output — 360 W continuous power at 40 °C
- 88 % efficiency (higher than the 12/12-30 model)
- Programmable as a charger or power supply (fixed output voltage configurable)
- Remote on/off via two-pole terminal
- Unlimited parallel operation to scale current
- IP43 protection when installed with terminals facing downwards
- Screw terminals: no special tools needed for installation
- Compatible with 12 V lithium (LiFePO4), AGM, GEL and lead-acid batteries
Compatible with lithium (LiFePO4) batteries
The Victron Orion-Tr Smart 24/12-30A is approved for charging 12 V LiFePO4 lithium batteries, with specific programmable charge profiles. It is ideal for mixed systems where the main bank is 24 V (typical in professional marine) and you want to keep a 12 V lithium auxiliary battery for sensitive electronics or specific applications.
It is also fully compatible with conventional AGM, GEL and lead-acid batteries — just select the corresponding profile in VictronConnect.
Bluetooth configuration with VictronConnect
Through the free VictronConnect app (iOS and Android) you can:
- Monitor voltage and temperature in real time
- Switch charge profile (lithium, AGM, GEL, lead-acid)
- Turn the charger on or off remotely
- Set absorption and float voltages
- Enable power supply mode with fixed output voltage
- Update the charger firmware

Frequently asked questions about the Victron Orion-Tr Smart 24/12-30A
Will this model work for my 12 V campervan?
No. The Orion-Tr Smart 24/12-30A is designed for 24 V main electrical systems that need to power a 12 V circuit or battery. If your campervan or van has a 12 V alternator and starter battery (like most), you need the Orion-Tr Smart 12/12-30A in either its isolated or non-isolated version.
What's the difference between the 24/12 and 12/12 models?
The 24/12-30A (this product) takes 24 V input and converts it to 12 V — it's a step-down converter. The 12/12-30A takes 12 V and delivers 12 V, keeping the voltage but stabilising it and applying intelligent charging. Choose based on the voltage of your vehicle or boat's main system.
Does it work with 12 V LiFePO4 lithium batteries?
Yes, fully compatible. It has a preconfigured lithium charging profile and lets you adjust all parameters from the VictronConnect app via Bluetooth.
Can I use it as a stable 12 V power supply in a truck?
Yes. Via VictronConnect you can configure "power supply" mode with fixed output voltage (adjustable between 10 V and 15 V). It's ideal for powering sensitive 12 V equipment (professional radios, navigators, instrumentation electronics) from the truck's 24 V system, eliminating the voltage fluctuation issues typical of alternators.
Is the Orion-Tr Smart 24/12-30A isolated or non-isolated?
This model (ORI241236140) is non-isolated: the input (24 V) and output (12 V) grounds are shared. It's suitable when both circuits share the chassis ground. If you need galvanic isolation (professional marine systems with independent grounds), Victron also offers an isolated version under a different part number — contact us for advice.
What cable size do I need for installation?
We recommend 10 to 16 mm² cable for both input and output depending on the run length. The maximum cross-section accepted by the screw terminals is 16 mm² (AWG6).
What is the warranty on a Victron Orion-Tr Smart 24/12-30A bought in the Canary Islands?
3-year legal guarantee against manufacturing defects, managed directly by BateríasCanarias from our shops in Tenerife. You won't need to ship the product back to mainland Spain — we handle the entire process.
