Nomadic X3 Helix 12V/48V DC Rooftop Air Conditioner
Meet the X3 Helix, the most powerful, feature-rich 12V/48V DC rooftop air conditioner for vans and RVs
The X3 Helix is a low-profile, battery-friendly rooftop AC built for real off-grid comfort. Control it from your phone, tablet, or watch; hold steady temps with intelligent PWM modulation; and clear cabin moisture with High Humidity mode. Choose 12V or 48V and a Black or White shroud. The 48V model is compatible with Ecoflow Power Kits via a custom 48v cable, allowing direct operation from a 48V battery alongside a typical 12V/24V distribution panel.
Built on proven X-Series fundamentals, the X3 Helix uses precise PWM compressor control for steady comfort with lower battery impact, spring-bushed compressor mounts to reduce vibration and noise, and a bright, high-contrast LCD with tactile buttons for glove-friendly control at the unit. Installation stays straightforward with a standard 14×14 roof opening.
Helix Highlights
- App and remote control: pre-cool, create scenes and schedules, and monitor from anywhere on phone, tablet, or watch.
- Smarter PWM cooling: smooth ramps, minimal overshoot, and steady temperature hold for longer runtimes and less battery stress.
- High Humidity mode: accelerates moisture removal after showers, coastal drives, or hot, sticky days.
- RV-C ready (optional): with the Helix AC Controller, the unit can publish status and accept commands on multiplex coach networks.
- Durable construction: sealed back plate shields electronics; automotive-grade water-resistant connectors; stainless hardware for corrosion resistance.
- Clean, low-profile interior: redesigned plenum for smoother airflow, plus a flush, powder-coated metal faceplate that preserves headroom.
- Modern refrigerant: R1234yf (low-GWP, A2L).
- Peace of mind: 1-year limited warranty with US-based support.

FAQ (Frequently Asked Questions) — click to expand
1.What’s new about the Helix version?
Helix adds full app/remote control, PWM compressor logic for steadier temps and lower battery stress, a High Humidity mode, and upgraded sealing/connectors with a flush interior plate.
2.Can it run from batteries only?
Yes. X3 Helix is a DC unit designed for 12V or 48V battery systems without requiring an inverter, generator, or shore power. We recommend pairing with the 48v Ecoflow Powerkits.
3.How do I choose between 12V and 48V?
Match the unit to your house battery voltage. 12V integrates with common van/RV banks. 48V pairs best with larger, high-capacity systems and reduces current over long cable runs.
4.Will it fit my roof opening?
Yes. It’s designed for the standard 14" × 14" roof cutout used on most vans and RVs.
5.What does the Helix app control?
Start/stop, target temperature, fan/compressor behavior, scheduling/scenes, and remote status checks from your phone, tablet, or watch.
6.What’s the difference between AC Only and AC + DIY Install Kit?
AC Only includes the rooftop unit, faceplate, controls, and mounting hardware. The DIY Kit adds wiring, adhesive, trim ring, and accessories to streamline a clean self-install. Full list above.
7.What colors are available?
Black or White.
8.Does the X3 Helix support RV-C / multiplex control?
Yes. When paired with the optional Helix AC Controller, X3 Helix can publish AC status and accept basic commands on standard RV-C networks, enabling coach-wide UIs while still operating standalone from local controls.
9.What is the warranty and how do I activate it?
The X3 Helix includes a 1-year limited warranty with US-based tech support. Follow the instructions in your documentation to activate coverage shortly after purchase.
10.What’s included with the AC-Only package?
Rooftop unit (Black or White), foam gasket (14×14), crossbars + mounting hardware, flush metal interior faceplate + screws, M8 mounting hardware, remote, leveling strip, foam air separator + screws, control panel + harness, and a full-size 14×14 cutout template. See image.
