Description
xVictron Orion-Tr Smart 12/24-10A (240W) Isolated DC-DC Charger
The Victron Orion-Tr Smart 12/24-10A is a galvanically isolated DC-DC charger that converts a 12V source (typically a vehicle or alternator) to a regulated 24V output at up to 10A (240W). It is designed for dual-battery charging in vehicles, boats and off-grid systems where electrical isolation between source and load is required.
Key Features
- Galvanic isolation between input and output, preventing ground loops and protecting sensitive electronics.
- Input voltage range of 12V with a regulated 24V output at up to 10A continuous (240W).
- Built-in Bluetooth via the VictronConnect app for configuration, monitoring and firmware updates without additional hardware.
- Adaptive charging algorithm supports lithium (LiFePO4) and lead-acid battery chemistries including AGM, gel and flooded.
- Engine detection feature prevents discharging the starter battery by monitoring input voltage before enabling the charger output.
- Programmable charge profiles allow the output voltage and absorption/float settings to be adjusted to match the connected battery.
- Wide operating temperature range with thermal protection and automatic power derating to prevent damage under high-temperature conditions.
Product Overview
The Orion-Tr Smart range uses a high-frequency transformer to provide true galvanic isolation between the input and output circuits. This is particularly important in marine and vehicle installations where multiple battery banks share a common chassis ground. Without isolation, charge current can flow through unintended paths, causing corrosion, interference or damage to electronics. The isolated design eliminates this risk entirely.
Configuration is handled entirely through the VictronConnect app over Bluetooth. There is no need for a separate interface cable or programming device. Installers can set the charge algorithm, absorption voltage, float voltage and current limit directly from a phone or tablet. The engine detection function monitors the input voltage and only enables the output once the alternator is confirmed to be running, protecting the starter battery from being drained by the auxiliary bank.
At 240W continuous output, this unit is suited to topping up a secondary 24V battery bank during transit rather than bulk charging from flat. For higher charge rates, Victron offers larger Orion-Tr Smart models. The unit is compact and wall or DIN-rail mountable, making it practical for installation in tight spaces such as vehicle cabinets or marine electrical panels.

Installation Notes
Installation should be carried out by a qualified electrician or experienced installer familiar with DC systems. Ensure correct cable sizing and fusing on both the input and output sides in accordance with the unit's rated current. For marine installations, follow NMEA or RCD Directive wiring standards as applicable. The engine detection threshold and charge profile must be configured via VictronConnect before commissioning. Lithium battery profiles should only be selected when the connected battery includes a compatible battery management system (BMS).
Return Policy
xWe offer a 14-day, no-quibble returns or replacement policy because we want you to be totally satisfied with your purchase.
If you are unhappy in any way with your purchase, you can return it for a refund or a replacement, as long as you return it in the same condition as it arrived (original/undamaged packaging and product) and within 30 days of receiving it.
