X2 Helix is the compact member of our X-Series — built for crews who want steady comfort, real remote control, and more roof room for solar without committing to an oversized battery bank. An efficient PWM compressor modulates instead of hard cycling, so your 12V RV air conditioner (or 48V) holds temperature smoothly with less draw. Pair it with Helix to add scenes, schedules, and true remote access on phone, tablet, or watch — pre-cool before you return and keep pets comfortable while you’re out.
- Even cooling: PWM-smooth modulation, less overshoot.
- Remote that reaches: Helix control from anywhere (not Bluetooth-bound).
- Compact footprint: frees roof space for solar and fits cleanly on racks.
- Clean interior: flush, powder-coated metal faceplate (no bulky plastic box).
- Humidity control: High Humidity mode keeps cabins crisp after showers or coastal days.
- US-based support: Elkhart, Indiana — level-one techs and engineers.
- Options: 12V or 48V; Black or White.
Bottom line: If you want rock-steady comfort, real remote control, and a system that plays nicely with a modest 12V bank, X2 Helix delivers — compact, connected, and ready for the miles.

Helix Ecosystem
The Helix Era has arrived
One app. Builder-grade hardware. Helix ties climate, camera, sensors, tank levels, lighting and awning control into scenes and schedules so your rig stays comfortable, informed and ready, even off-grid. Set day, night and away routines to pre-cool, hold a quiet low-RPM night, switch lights on and off, extend or retract the awning with weather-aware rules, and alert on leaks or temperature spikes. You arrive to perfect; Helix handled the rest.

Does X2 Helix Beat the Alternatives
Steady Temps
Holds the set point: without the roller-coaster
X2 Helix uses efficient PWM modulation with improved control logic to glide to temperature and hold it with less battery stress. Many budget units hard-cycle on/off, overshoot, and feel noisy even when the numbers look similar.
Beyond Bluetooth
Control that follows you, not the other way around
Set scenes and schedules and adjust climate from phone, tablet, or watch—pre-cool before you arrive and check on pets from anywhere. Bluetooth-only systems stop at the door; Helix gives true remote access.
Flush Interior
Clean cabin look; no bulky plastic box
The powder-coated metal faceplate sits low and flush, preserving headroom and elevating the interior. Many alternatives protrude inches into the cabin with plastic bezels that look and feel cheap.
Sealed Electronics
Protected where it matters, service-minded by design
A sealed back plate shields control electronics from dust and debris, and automotive-grade, water-resistant connectors beat messy sealants. Logical access points and clean harness routing make maintenance straightforward on the road.
Beat Humidity
Sticky air? Handled
High Humidity mode increases moisture removal after showers or coastal drives so the cabin feels crisp, not damp. Most systems treat humidity as an afterthought
Built to Last
Stainless hardware that resists salt and seasons
Hardware & fasteners are stainless by design to handle coastal air and winter roads. That keeps mounts solid and finishes clean after miles, where budget hardware can rust and loosen.
US Support
Real help, from Elkhart, Indiana
Talk to level-one techs and engineers who know off-grid builds and the X-Series install flow. When you’re on the road, you need answers—not scripts, emails, or unit replacements by default.
Future-Ready
Modern refrigerant, chosen for longevity
With R1234yf, X2 Helix pairs low global warming potential with low-flammability classification and prudent charge sizing—avoiding the hydrocarbon shortcuts found in many budget units. A smarter path as regulations tighten.
FAQs
How is the X2 Helix different from the X2 Plus and the X3 Helix?
X2 Helix keeps the compact X-Series footprint but upgrades the X2 Plus with Helix automation (scenes, schedules, true remote), improved control logic, a sealed back plate, automotive-grade water-resistant connectors, a refined plenum/air separator, and R1234yf refrigerant—while still using PWM for smooth, steady cooling. X2 Plus shares much of the core hardware and PWM approach, but lacks Helix integration and the newer control/sealing updates. Versus X3 Helix, the X2 Helix is smaller and lighter, pairs well with a more modest battery bank, and suits tighter builds; X3 is the larger flagship for rigs that want the bigger footprint and capacity envelope.
Will it fit my build and what does installation involve?
Yes—X2 Helix drops into the industry-standard 14×14 roof opening and follows the familiar X-Series process: dry-fit with the template, seat the gasket, set the unit level, secure crossbars/fasteners in a criss-cross pattern, wire DC (12V or 48V), and commission. The compact footprint helps preserve roof space for solar/racks. Choose Black or White. Step-by-step guides and wiring diagrams are in Install, Fit & Downloads.
How quiet and stable is the X2 Helix at night?
PWM modulation glides to the set point and holds it with fewer start/stop spikes, which softens perceived sound. Create a Quiet Night scene in Helix to maintain comfort at lower compressor RPMs, and dim or turn off the control-panel light for a dark cabin.
How do I maximize runtime off-grid (battery life and comfort)?
Pre-cool the cabin, use reflective window covers and shade (awning), keep airflow paths clear, and set a realistic target temp. In Helix, create a “Quiet Night” scene to hold comfort at lower compressor RPMs and use High Humidity mode after showers or coastal drives.
What maintenance and support should I expect over time?
X2 Helix is service-minded: protected electronics, clean harness routing, and sensible access. Periodically inspect gasket compression and connections; consult the Install/Troubleshooting guides. If you need help, our US-based team in Elkhart, Indiana, supports you, and warranty coverage is 1 year.
