Product Details

The Victron Orion-Tr Smart 12/12-30A Non-Isolated DC-DC Charger is a high-quality battery to battery charger designed for 12 V vehicle or boat systems. Ideal for trade and retail buyers, this unit converts the alternator’s output to reliably charge a service battery while protecting the starter battery. According to Victron, it can also serve as a DC-DC power supply.

With a rated 30 A continuous output at nominal output voltage and full output up to 40 °C, this charger delivers around 360 W of output power in its 12/12-30 configuration. It features an adaptive three-stage charge algorithm (bulk, absorption, float) that automatically adjusts absorption time for lead-acid or lithium battery types. Built-in Bluetooth allows monitoring and configuration via the VictronConnect app for real-time insights from a smartphone or tablet.

The non-isolated design means input and output share chassis ground, making it a compact and cost-effective choice for dual battery setups where isolation is not required. The housing incorporates screw-terminal connections and supports ambient temperatures up to 55 °C (with full rated output to 40 °C). It’s engineered with professional build quality, and multiple units can be connected in parallel to increase output current for larger systems.

Perfect for camper-vans, fleet vehicles, service trucks, or marine setups where you want reliable service battery charging from your starter battery or alternator, the Orion-Tr Smart 12/12-30A provides excellent performance, smart connectivity, and installer-friendly integration.
