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.

I'm excited to start using this panel in my off grid system I'm building. I have a truck tool box I have 3 lifepo4 100ah batteries and a victron 100-50 charge controller. 3000watt power inverter. I will have 120 and 12 volt out puts. and all the wiring and fuses and switches I need for my build. This panel I will mount to the top of the box. Only thing I could gripe about is the corners of the panel are very sharp and a concern about cutting myself is the only thing I can complain about but that's not really a issue. Kinda wish the panel would at least have came with basic mounting hardware. It ships with just the panel and nothing else not even a spec sheet. Over all I'm happy to complete my project using this high quality panel.

Thanks for the review, and glad the panel is a good fit for your off grid build, that sounds like a solid setup. Good callout on the corners. They’re aluminum and can feel sharp out of the box, so we always recommend handling with gloves during install. On the specs, they’re on the sticker on the back of the panel.

The Comvolt 4200 (with AC/DC PDU and 7-inch screen) is a game-changer for any setup.
Super easy install—mostly plug-and-play with minimal wiring. No fuss, no extra components to hunt down.
It’s compact, portable, and incredibly versatile: works flawlessly off-grid in a van, car, shop, home, or anywhere else. Everything’s built right in, so you get clean power without the headache of piecing together a bunch of parts.
Expandable too if you need more juice later. Hands down one of the most convenient, reliable portable power stations out there.
Nice work, Comvolt team—I love it! Highly recommend.
Thank you Orion Van Gear

Thanks so much for the great review. We’re stoked you loved the Comvolt 4200 and really appreciate the shout out. Also loved your YouTube video on it, great walkthrough. For anyone reading this, be sure to check out Reds Custom OffRoad’s YouTube video to see the system in action.

Nice addition to our awning’s lifespan.

Great side ladder for Ford Transit! We've got a 2023 Ford Transit 350 High Roof XL AWD with the Orion Van Gear Stealth rack and just installed the side ladder to go with it. It fits nicely with the side profile of the van and has been rock solid on two road trips so far. If you've got a roof rack and need an easy way to climb up to it, this is a great fit.

Thanks, Travis. Happy to hear the side ladder has been a solid fit on your Transit and is holding up well on the road. Appreciate you taking the time to share your experience.

Great roof rack for Transit! We've been rocking the Stealth Roof Rack on our 2023 Ford Transit 350 High Roof XL AWD for a year now and it's been excellent. No noise, vibration, wind drag and it's designed nicely to snug up against the roofline. We ordered ours with the 2X scene (rear flood) lights and I highly recommend that. It's a nice easy way to shine some light on your loadouts and load-ins at night or while the sun is coming or going!

Stoked to hear the Stealth rack has been treating you well and staying quiet even after a year of use. The rear scene lights are a great call, super handy for night load-ins and early mornings. Appreciate you sharing the feedback.

Great rack for my 2023 Ford Transit 350 High Roof XL AWD! Have had it on for a year now and have no noise, vibration or wind drag issues. It's solid and nicely designed to lay flat against the roofline.

I am adding an extra battery to my system. The Ecofliw has been a great system. This will double the capacity. It was very easy to adopt and it is working flawlessly. Shipping was quick and I didn’t have any issues.

Thanks for the feedback. Glad to hear the EcoFlow system has been solid for you and that adding the extra battery was easy. Doubling the capacity makes a big difference. Appreciate you sharing your experience.

I had no issues with the installation of this fan. I was removing a Maxxair fixed vent unit in my car trailer and the opening was 14¼" x 14¼". An opening any larger and **** down the new unit would have been difficult. The only reason for 4 stars and not 5 is that the IR beam on the remote control is very narrow and has to be pointing directly at the unit in order to operate - I was hoping to use the remote while it was seated in the wall holder near the door, but no big deal.

Thanks for the detailed feedback. Glad to hear the install went smoothly and the fit worked well. The remote can be a bit finicky, but as you noted, it works when pointed directly at the unit. Appreciate you sharing the honest notes.

I questioned ordering from Orion Van Gear but they had good reviews so I gave it a try. I ordered a Maxxair 00-07500K vent fan, they had it at a very good price. I received it in a week, the part was what I ordered and in good shape. I would recommend Orion Van Gear, if they have something I need, I would use them again. I won't Install the fan until spring (it's December now) so I can't give a review on how the fan works.

Thanks Larry. Glad the order arrived quickly and everything showed up exactly as expected. Appreciate you giving us a shot and the recommendation. Hope the install goes smoothly this spring.
