Energy storage system ProEnergyBox

The EFOY ProEnergyBox has been developed for use in all weather conditions between – 40 °C and + 50 °C. One EFOY Pro fuel cell, up to two batteries, a solar charge controller and a maximum of two M28 fuel cartridges can be integrated in the EFOY ProEnergyBox. This guarantees long autonomy without user intervention. Effective temperature regulation means that the waste heat from the EFOY Pro fuel cell can be used when the temperature is below zero to keep the energy solution warm and to prevent the battery and electronics from freezing. For high ambient temperatures, an effective heat conduction system has been implemented to protect the components in the box from heat. The EFOY ProEnergyBox offers sufficient space for customer-specific installations and can be configured to the individual customer’s needs. The EFOY ProEnergyBox is compatible for hybrid operation with solar power and is therefore perfect as a back-up or extension for solar energy systems. “The ProEnergyBox kept our systems continuously running during a very important time, allowing our ASFS to capture the important transition that occurs during the onset of the summer melt season.” During the expedition, we were only able to access our remote sites at infrequent intervals, but through remote monitoring we could ensure that operations were maintained at these sites. Importantly, due to the COVID-19 pandemic, our research vessel and all research personnel had to leave the sea ice for more than a month.
