What is a DC-DC charger and why do you need one?
A DC-DC charger transforms the direct current voltage from the alternator or starter battery into an optimised, multi-stage charging voltage for the auxiliary service battery. Without one, LiFePO4 lithium batteries won't fully charge from the alternator, and AGM or GEL batteries stay only partially charged, shortening their service life.
Available types include step-up converters (from 12 V to 24 V), step-down converters (from 24 V to 12 V) and same-voltage models (12/12, 24/24) that act as intelligent charging boosters.
Differences between Victron Orion-Tr and Orion XS
The Victron Orion range is split into two families:
- Victron Orion-Tr Smart: available in isolated (galvanic isolation) and non-isolated versions. Bluetooth configuration via the VictronConnect app. Output currents from 9 A to 30 A. Ideal for installations that need protection against stray currents.
- Victron Orion XS: new generation (2024), non-isolated, with efficiency above 97 % and output currents up to 50 A. More compact and cost-effective per amp. Designed for modern campervan installations with lithium batteries.
Applications of DC-DC chargers in the Canary Islands
- Campervan, van and motorhome: charges the lithium auxiliary battery while you drive around the islands.
