Battery compliance doesn’t need to be confusing.

AS/NZS 3001.2 sets out clear requirements for safe caravan and vehicle electrical systems and one of the most commonly missed areas is ventilation.

In many cases, it’s not about changing the battery itself. It’s simply about adding a compliant venting solution as part of the overall system.

That’s why we focus on practical, compliance-ready setups that make it easier for owners and installers to get it right.

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.
