The refrigerator — the largest consumer in your camper van
In most camper vans and boats, the refrigerator or cool box is the largest consumer of the electrical system. A compressor refrigerator draws 30–60W when it is on, but the compressor does not run continuously — it switches on and off to maintain the desired temperature. The actual daily consumption is therefore 300–600Wh per 24 hours. When dimensioning your battery and solar panels, the refrigerator is the first appliance you take into account.
Compressor — the only choice for serious off-grid use
A compressor actively cools independently of the outside temperature — even at 35°C outside, it cools your food to 4°C. A thermoelectric cool box only cools 15–20°C below the ambient temperature — totally insufficient in hot weather. An absorption refrigerator works well on gas, but for self-built camper vans, this is not a sensible choice. Incorrect installation of a gas appliance can lead to incomplete combustion and CO poisoning — an invisible and life-threatening risk. For self-builds, a compressor is always the safe and right choice.
Refrigerator or cool box — what suits you?
A compressor refrigerator is a fixed unit that you install in the camper van. A compressor cool box is a loose unit that you can also use outside the camper van. Both use the same compressor principle and are equally efficient — the difference lies in the form and flexibility of use.
Consumption and battery — keep this in mind
Count on 300–600Wh per day — depending on the model, capacity, and ambient temperature. At higher outdoor temperatures, consumption increases. Make sure your battery capacity and solar yield cover at least this item, plus a margin for the rest of your consumers.
