Abstract

The present invention relates to an apparatus configured to manage energy consumption of a freezer or cooler to match available solar energy, the apparatus comprising a controller connectable to associated components in the freezer or cooler, said controller comprising a measuring logic configured to measure parameters selected from the group consisting of current from a solar array, ambient temperature, freezer temperature and battery temperatures, battery voltage and battery current, and availability of an external power supply or a combination thereof, a calculating logic configured to determine availability of excess solar energy beyond that required to maintain the freezer or cooler at its normal set temperature, a memory having the ability to store values and external inputs values, and wherein said controller is configured to control the temperature set point of the freezer or cooler, to utilise solar energy that is available in excess of that required to maintain normal operation of the freezer or cooler in order to lower the temperature set point of the freezer or cooler. The invention also relates to methods of managing energy consumption of a freezer or cooler to match available solar energy.
