Victron Energy Orion DC-DC Converter 24/12V 70A Non-Isolated — Compact High-Current with Remote On-Off

The Victron Energy Orion 24/12-V 70A DC-DC Converter Non-Isolated converts 24V vehicle or vessel power into a stable 12V output capable of supplying up to 70 amps for accessories, batteries, and electronics.

This compact, non-isolated DC-DC converter is designed to deliver a dependable 12V supply from a 24V source without complex wiring or heavy switching hardware. It’s built for mobile and off-grid environments — trucks, boats, RVs, and equipment — where you need a robust, high-current 12V feed from a 24V main system. The unit supports remote on-off control, adjustable output models can act as dedicated battery chargers, and multiple units can be paralleled to scale current capacity.

How does this converter fit into a 24V vehicle or boat electrical system?

The converter installs inline between the 24V source and the 12V loads or battery bank. It replaces bulky mechanical switches since the remote on-off input allows control from a low-current switch or the engine run circuit. Because it’s non-isolated, it’s compact and efficient when sharing a common ground.

• Direct 24V-to-12V conversion with up to 70A continuous output
• Remote on-off input removes need for high-current input switches
• Common-ground (non-isolated) design for simpler wiring
• Suits trucks, marine craft, RVs, and industrial equipment

Can it charge a 12V starter or accessory battery from a 24V alternator?

Yes — models with adjustable output can be configured as battery chargers to maintain a 12V starter or accessory battery while the 24V alternator runs. Set the output voltage appropriate for the battery chemistry and the unit will provide regulated charging current. This creates a dedicated charging path without overloading the 24V system.

• Adjustable output versions support controlled battery charging
• Regulated voltage prevents over- or under-charging
• Useful for maintaining starter, accessory, or house batteries
• Connects in parallelable sets for higher combined current

What protection and installation conveniences does it offer?

The Orion includes features that simplify safe installation and operation in mobile environments. The remote on-off connector lets you switch the unit without running heavy-gauge wiring through the cabin. While non-isolated converters share a common negative, their design lowers size and thermal demands compared with isolated units.

• Remote on-off reduces need for heavy input switching components
• Compact footprint for tight equipment bays and panel spaces
• Parallel-capable for up to five units to increase output current
• Widely used across vehicle, marine, and RV electronics applications

How can I increase output if my loads exceed 70A?

If a single 70A converter isn’t enough, you can parallel multiple adjustable-output Orion units to multiply available current. Victron allows up to five units in parallel; each unit shares load evenly when configured correctly. Make sure wiring and fusing are sized for the combined current and follow the manufacturer’s parallel-connection guidance.

• Connect up to five identical Orion units in parallel for higher current
• Ensure matched settings and proper balancing wiring for shared load
• Upgrade cabling and overcurrent protection to match total amperage
• Helpful for powering heavy accessory banks or charging large 12V banks

Who is this for: The Victron Energy Orion 24/12-V 70A Non-Isolated DC-DC Converter is aimed at professional installers, fleet operators, boat owners, and RV or off-grid enthusiasts who need a compact, high-current 12V supply from a 24V source. It suits situations where a reliable 12V feed, remote control, and the option to parallel units for extra capacity are priorities. Choose this unit when you want proven hardware that integrates with vehicle and marine electrical systems while minimizing bulky switches and complex wiring.
