D1 – Robust DC to DC Converter for Off-Grid Vehicles
D1 - Product Details
What is the D1?
The Nomadic Controls D1 is a rugged, high-efficiency DC to DC converter engineered for vans, RVs, expedition vehicles, and off-grid electrical systems. Built with bidirectional charging, intelligent voltage regulation, and automotive-grade protections, the D1 ensures seamless, safe, and optimized power flow between your primary and auxiliary battery banks. Whether you’re stepping voltage up or down, the D1 delivers reliable 12V output from 24V or 48V sources—perfect for lithium battery systems, solar charging banks, or alternator-powered setups. Waterproof, shockproof, and designed to meet strict vehicle compliance standards, the D1 is a powerhouse of stability and efficiency in even the harshest conditions.
Biggest Benefits of D1
The D1 stands apart as a professional-grade converter for demanding mobile power systems. With its bidirectional capability, the D1 doesn’t just convert power—it manages it intelligently. That means smarter battery charging, regenerative energy use, and dynamic power routing between your vehicle’s systems. Thanks to Buck and Boost modes, the D1 adapts to your system's needs, stepping voltage up or down with high precision and over 95% efficiency.
And with its compact IP67-rated chassis, it's ready for road vibrations, water, dust, and heat—making it ideal for overlanders and professionals who need gear they can trust.
Fully compatible with CAN (RVC) systems, the D1 offers real-time data monitoring and integration, empowering builders and users to make better energy decisions without the guesswork.
What About Installation?
Although it’s a powerful piece of tech, the D1 was designed with clean, efficient installation in mind. It mounts easily on flat surfaces using its reinforced flanges, with thermal isolation to help manage heat dissipation. The signal connector interface supports CAN communication, ignition triggers, and remote control, giving installers maximum flexibility. Wiring is straightforward with clearly labeled input/output terminals and a diagnostic-ready signal connector.
While professional installation is strongly recommended—especially for high-amperage, dual-battery setups—the D1 also comes with quick-start diagrams, a wire sizing chart, and full documentation to support custom or advanced installs.
How The D1 Compares?
When it comes to managing power in your vehicle, not all converters are created equal. The Nomadic Controls D1 isn’t just another DC-DC box—it’s a purpose-built solution engineered for life on the road and in the wild. Unlike generic converters that struggle with durability or compatibility, the D1 is designed to meet strict automotive-grade standards like ISO 26262 (ASIL B), CISPR 25 Class 3, and LV124/LV148. That means it’s tested and trusted to perform in real-world vehicle environments—heat, vibration, voltage fluctuations, and all.
But what really sets the D1 apart is its intelligent bidirectional charging. It doesn't just convert voltage—it actively optimizes it, directing power where it’s needed most between your start and house batteries. Whether you’re solar-heavy, alternator-dependent, or switching between sources on the fly, the D1 adapts in real time with over 95% efficiency and advanced fault protection built-in.
Add to that IP67 waterproofing, passive fin cooling, CAN-based system visibility, and a footprint that fits almost anywhere—and you’ve got a power solution you’ll never second-guess.

The NEW D1 Converter
Your power, reimagined: smarter energy management, bidirectional charging, and rock-solid protection—built for real off-grid travel.
Why the D1?
When your entire rig depends on stable energy, you can’t afford power bottlenecks or wasted amps. The D1 DC‑DC Converter delivers intelligent bidirectional energy flow, enabling battery‑to‑battery charging, solar‑to‑battery input, and seamless buck/boost regulation—all without sacrificing efficiency. At just under 3 inches tall, it's compact enough for tight builds, rugged enough for expedition rigs, and smart enough to adapt to the needs of modern overlanders and off‑grid systems. Whether you're running 12V, 24V, or transitioning between banks, the D1 brings energy where it's needed—when it's needed.
FAQs
Please read our FAQs page to find out more.
How is the D1 different from a standard DC-DC charger?
The Nomadic Controls D1 isn’t just a DC-DC charger—it’s a bidirectional power management system. While traditional converters move energy in only one direction (often from alternator to house battery), the D1 intelligently manages power in both directions, making it ideal for setups with lithium battery banks, solar systems, and alternator charging. It also features buck and boost modes, allowing it to adapt to various voltage mismatches between power sources and battery banks. It's designed for the next generation of off-grid rigs.
Will the D1 work with my current battery setup?
Most likely! The D1 is built with versatility in mind. It supports a wide input/output range, making it compatible with 12V, 24V, and mixed-voltage systems. Whether you’re tying into an alternator, solar charge controller, or another DC source, the D1 ensures your batteries charge safely, efficiently, and without voltage conflicts. For best results, we recommend professional installation—especially for complex electrical systems.
What kind of support or warranty is included?
All D1 units are backed by Nomadic’s one-year limited warranty, covering defects in materials and workmanship. We also offer U.S.-based technical support, full installation documentation, and system integration guidance for upfitters and DIY builders alike. If you need help with system design or troubleshooting, our support team is just a message away.
