Isolated or non-isolated - which DC-DC charger do you actually need?

Here’s a simple explanation to help you choose the right Victron Orion model for your setup.

🔧 Non-isolated works for 99% of caravan and 4WD systems
⚡ Smaller, more efficient and higher output (50A vs 30A)
🛠️ Choose isolated only when a common ground can’t be shared
🔋 Example: charging two separate 12V batteries from one 24V source
🚫 Two non-isolated chargers in that scenario would create a short circuit

Still unsure? Send us a message - we’re happy to help you pick the right charger for your build.

Thinking about a DC-DC charger upgrade?

Here’s when Bluetooth is worth the extra dollars - and why it makes troubleshooting so much easier when you’re travelling.

🔧 Instant visibility into what your charger is doing
⚡ Quickly see if power is flowing in or out
🛠️ Faster fault-finding when something isn’t working
📱 Easier to adjust settings and monitor performance
🚐 Especially helpful when you’re out bush with no mechanic nearby

Our take: Bluetooth isn’t essential, but it makes life a whole lot easier on the road.
