Compact 12V RV Air Conditioner for Off-grid cooling
Stay cooler in your van, RV, or overland build while keeping more roof space free for solar and racks. This DC rooftop air conditioner uses PWM-smooth compressor control, Helix remote access, and a standard 14 in × 14 in roof opening for a clean, battery-conscious install.
Benefits & Use Cases
Built for off-grid comfort, the X2 Helix is designed for travelers who want steady cooling without committing to an oversized battery bank. The compact footprint helps preserve roof space, while Helix control lets you pre-cool the cabin, set scenes, and adjust comfort from your phone, tablet, or watch.
- Compact rooftop footprint leaves more room for solar panels, roof racks, and van accessories
- PWM modulation helps hold the target temperature smoothly without harsh start-stop cycling
- Helix scenes and schedules support day, night, away, and pre-cool routines
- High Humidity mode helps clear moisture after showers, rainy days, or coastal travel
- Flush powder-coated metal interior faceplate gives the cabin a clean, low-profile finish
- Stainless hardware, sealed back plate, and automotive-grade water-resistant connectors support road use

FAQs
Will this fit my van or RV roof opening?
The X2 Helix is designed for the common 14 in × 14 in roof opening used in many van and RV builds. Always dry-fit with the included 1:1 template before sealing or wiring.
Is the X2 Helix suitable for off-grid cooling?
Yes, it is built for DC battery systems and uses PWM modulation to help maintain steady cooling. Pair it with a properly sized battery bank, solar setup, and realistic temperature targets for best runtime.
How can I improve cooling performance in hot weather?
Pre-cool the cabin, use reflective window covers, keep airflow paths clear, and use shade when possible. These steps reduce heat load and help the air conditioner hold a comfortable set point.
Can I control it remotely?
The Helix platform supports remote control, scenes, schedules, and advanced settings from a phone, tablet, or watch. This makes it easier to pre-cool before returning to the vehicle or keep the cabin comfortable while parked.
Does it work well with solar?
The compact rooftop footprint leaves more room for solar panels, which is useful for off-grid builds. Final runtime depends on your battery capacity, charging setup, insulation, sun exposure, and temperature settings.
Can it help keep pets more comfortable?
Remote access can help you monitor and adjust cabin comfort while you are away from the vehicle. Never rely on climate control alone for pet safety without backup power planning and regular checks.
