Sounds like a nice unit, but oh, the marketing hype
- The device not only makes your fridge intelligent but also allows the storage of a significant amount of cold energy into the loaded food and drinks
There is no such thing as
cold energy, cold is the absence of energy.
- The cooling energy is stored when a power surplus is available (engine on or connection to grid) and reused first..,
Loosely translated, when system voltage is high due to motoring or connected to shore power, the food is chilled to a temperature below the typical 38* but not so cold that the beer freezes. This allows the temperature rise 6 to 8 degrees before the unit comes back on. If only on battery power, it keeps the food slightly warmer probably at 38*. Saves on battery power. Smart feature, poor marketing hype.
Anyway, Webasto has a good reputation. Enjoy your cold beer this summer and do monitor the SOC of your batteries so you don' t get left out in the heat.
