The above energy information is based on reported temperatures of environment and on the regular use with import and export of products of refrigeration. The particular size of unit is reported in daily operation in temperature of environment 25th C. In wintry operation, the recommended attribution of element should it is calculated individually. The elements that are reported by the constructors and that are in effect according to DIN 8953 concern empty refrigerators.  In real use they owe to be calculated, as it is reported in the table (see above).

Low energy consumption, 32 L net interior volume, Runs both with top or front door, Handle for easy moving, Rugged plastic cabinet, Especially designed for use in solar systems.
The SF32E is a new type of cooling box especially created for the use in photovoltaic solar systems. Due to its good insulation, a new type of solid-state semiconductor cooling device and an advanced electronic regulation it has a very low power consumption. Because it is not a compressor-type cooling system, the SF32E produces almost no noise. The internal electronics switches automatically to a special ”Power Mode“ as soon as the battery has reached a high state of charge. Therefore ? of energy is consumed during excess energy periods in solar systems. This Cooling Box has a sophisticated microprocessor control unit which allows excess energy use if the fringe is connected to a CR10LC, CR20LC or CR30LC regulator. The SF32E consumes more energy during daytime to reduce nighttime energy consumption. This leads to a better utilization of solar energy and the possibility to use smaller batteries. Two interior temperatures can be selected.

Depending on the requirements are sold models 165 and 225 as Refrigerator - Deep Freezer. The appliances do not require maintainance and the intelligent low-frost system decrease the creation of ice. The used means of refrigeration is friendly to the environment and the internal temperature is regulated.
