The reduced noise level alone makes it worth the price - a considerable improvement over the Dometic.A unique 12V roof air conditioner designed for use in campervans, motorhomes and van conversions up to 6 metres. But if started in the morning when temps are about 75-80 deg, Eco mode is pretty efficient with little battery drain. (It's a dry heat!) Obviously the Velit has to work hard (Turbo mode) to cool the Sprinter down after sitting in 108 deg sun all day. I live in Moab, UT where we have been 100 deg or more every day for the entire month of July. Once installed and connected to 400 ah LiFePo4's supported by 300 watts solar we were in business. The components are high quality the rooftop sealing gasket was virtually a duplicate of the original Dometic and the unit occupies less rooftop real estate which helped the installation process, improved aerodynamics and increased my solar view. So the remote isn't the highest quality but it does the job. I am a retired mechanical/electrical/software engineer so no stranger to HVAC. The Velit installation in my 2021 Sprinter was actually easier than removal of the Dometic. Replaced my nearly new Dometic Penguin A/C unit with the Velit 2000R. Great job Velit for listening to what customers really want and giving it to them at an affordable price. Now when we go off grid camping, our battery lasts longer than our water does. We have tested the unit and, to our delight, have found out that running the Velit makes our camper air feel like our house and much quieter than our old rooftop unit.
Most other DC air conditioning units make you buy them separately.

When the box arrived we saw everything packaged neatly and all the necessary supplies for install included. We looked at other DC units that were all MUCH more expensive before going with Velit. Additionally, we had to run our inverter all the time since the air conditioner was AC current. We always had issues with uncomfortable sleep due to high humidity levels not to mention how loud our rooftop Dometic was. We have five 12 volt 200AH lithium batteries and a 3000 watt inverter.
As a result you save energy, money and are much more comfortable.Īfter researching many options, we decided to install the Velit 2000R on our 2020 Rockwood GeoPro 19 foot bunkhouse model. The compressor stays on longer and more moisture is removed from the air. This means no more short cycling and much lower humidity. Secondly since the Velit has a variable speed compressor, the compressor can slow down to better match the space of your RV and outside temperature. If you are running an AC unit in your camper off battery power, that makes a huge difference. Inverter losses average around 10% of the total energy supplied by the inverter. First of all it is a DC unit which means no more wasting energy on running an inefficient inverter for an AC unit. So, how can you lower humidity levels in your camper and save energy and money? That's where the Velit 2000R comes in. With proper humidity levels you can actually raise your thermostat temp by around 5 degrees without sacrificing comfort. Lower humidity levels are much more efficient too. That wastes energy that boondockers work hard to capture with solar panels and store in battery banks. Most people compensate for higher humidity by turning the thermostat down. Using those oversized, single stage units in most RVs means the compressor doesn't stay on long enough.
This only happens when the AC compressor is on. This is the moisture being removed from the air in your camper and draining outside. This is why water runs down the roof of your camper and onto the ground when the AC is on. When an air conditioner compressor comes on, the heat exchanger coil inside the air conditioner becomes cold enough to condense the moisture in inside air thus lowering humidity. This is called short cycling and it leaves you with a humid, uncomfortable air inside your RV. If the temperature is not extremely hot at night or your AC unit is oversized (most RV AC units are) this means the compressor only runs a few minutes at a time.

Having a single speed compressor AC unit means that when the temp in your camper gets above your thermostat setpoint, the compressor kicks on full speed, drops the temp quickly and shuts back off. No matter how small your camper is, you usually get a 13.5K or a 15K BTU single speed compressor unit. RV manufacturers have 2 go-to camper air conditioners.
