Camper van builds need a true 12V DC parking AC — not a 120V residential mini-split running off an inverter. Vethy's 12V parking AC line is built for Mercedes Sprinter, Ford Transit, Ram ProMaster and Iveco Daily camper conversions, with low current draw and a thin profile that fits typical van roof geometry.
Why a native 12V parking AC beats a 120V mini-split for camper vans
- No inverter losses (15 to 25 % gone with a 120V setup).
- Quieter — typical mini-splits run at 55 to 60 dB outdoor.
- Battery-direct operation matches off-grid life.
- Lower install complexity.
Recommended Vethy models for camper vans
- VS02-PRO rooftop parking AC – 12V/24V R410A twin-rotor, flagship sleeper cab cooling.
- VX3000SP split parking AC – 12V/24V split, condenser-evaporator separated.
- VM6000 Max high-power rooftop AC – oversized cabs and double-bunk trucks.
- ZH800 inverter rooftop AC – low current draw for battery-sensitive fleets.
Solar and lithium pairing
A 300 to 400 Ah lithium pack + 300 W roof solar typically sustains 24/7 cooling on a VS02-PRO or ZH800 in summer touring conditions.
Vethy supports three buyer paths: fleet direct, OEM and upfitter, and distributor and wholesale. Request a quote or email info@vethy.com.
Frequently asked questions
Will the Vethy parking AC fit a Sprinter high-roof?
Yes. The VS02-PRO uses a 360 × 360 mm cutout that fits high-roof Sprinter, Transit and ProMaster between the standard roof crossbeams.
Can it run off solar only?
Continuous solar-only operation needs at least 400 W of roof solar plus a 200 Ah lithium buffer. For nightly use, a 300 to 400 Ah lithium pack is standard.
Is it loud inside the van?
Night-mode noise <49 dB(A) at the sleep position. Most owners report it is quieter than residential window units.
Do you support van builder OEM programs?
Yes. See <a href="/truck-parking-ac-manufacturer.html">truck parking AC manufacturer (OEM/ODM)</a>.
