Victron Orion-Tr Smart 12/24 10 AMP (240W) Isolated DC-DC Charger or Power Supply

The Victron Orion-Tr Smart 12/24 10 AMP (240W) Isolated DC-DC Charger is purpose-built for serious anglers and boaters who demand reliable auxiliary power management on the water. Whether you're running a trolling motor, GPS, sounder, or cabin systems from a dual-voltage setup, this isolated converter bridges 12-volt and 24-volt systems without the ground loop noise and battery drain that plague conventional chargers. Built by Victron Energy—the gold standard in marine power electronics—this unit handles the unique demands of extended fishing trips and extended cruising where redundant charging and stable voltage are non-negotiable.

The 10 amp output at 240 watts delivers sufficient charging current to top off auxiliary batteries, power inverters, or supply stable DC bus voltage without voltage sag when multiple accessories run simultaneously. Isolation—the key differentiator here—completely separates input and output circuits, eliminating ground-loop hum in VHF radios and depth sounders while preventing backfeed that drains the primary battery. The Smart variant includes Bluetooth monitoring via the VictronConnect app, allowing you to track charge status, input/output voltage, and current draw from your phone or chartplotter, and supports advanced settings like absorption time and float voltage tailored to lithium or lead-acid chemistry. Compact dimensions (5 × 4 × 8 inches) and minimal weight (3.1 lbs) make installation flexible in tight helm spaces or engine compartments.

This charger excels on center-console fishing boats, cruising sailboats, and RVs with mixed 12V/24V architectures—scenarios where a single battery bank can't reliably power both engine systems and auxiliary loads. It integrates seamlessly with Victron's ecosystem (MultiPlus inverters, SmartSolar controllers, BatteryProtect switches) for a fully networked power system you can monitor and adjust underway. Installation requires basic DC wiring skills: secure battery connections, inline fusing, and a control wire to the house battery. The galvanic isolation makes it essential for vessels with both 12-volt trolling motors and 24-volt engine-start systems, or any setup where noise-free, independent charging is critical to fishing success.
