EFOY ProEnergyBox

Complete, off-grid energy solution for all weather conditions

Long autonomy in all temperatures

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.

Individual configuration

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.
