The last thing you want to do after you have invested in an alternative energy system powered by batteries and an inverter is to waste precious energy via inefficient appliances and fittings.
Refrigeration can be the single biggest consumer of energy in an alternative energy setup, as it is connected 24 hours a day, seven days a week.
Standard household refrigerators and freezers are power hungry devices even by modern standards and when compared to our available range of energy efficient models, it makes good economic sense to change to something more frugal.
Both the Vestfrost and Gram brands are world leaders in energy efficient refrigeration, and can save as much as 50% on refrigeration energy requirements.
What this can mean is a substantial saving in installed battery capacity (because you don't need as many batteries to run an efficient 'fridge), often to a level where those savings far outweigh the initial cost of the energy efficient 'fridge, it's that plain and simple!
