EFOY ProEnergyBox

EFOY ProEnergyBox

Off-grid energy solution
for all climate scenarios

Application of the EFOY ProEnergyBox

The EFOY ProEnergyBox has been developed for use in all climate scenarios at temperatures from - 40 °C to + 50 °C (- 40 °F to + 122 °F).

Long autonomy

One EFOY Pro fuel cell generator, up to three batteries, a solar charge controller and max. two M28 fuel cartridges can be integrated into the EFOY ProEnergyBox. A long autonomy without any user intervention is warranted.

Extended temperature range from - 40 to + 50 °C (- 40 °F to + 122 °F)

Thanks to effective temperature regulation, the heat given off by the EFOY Pro fuel cell generator can be used in sub-zero temperatures to keep the energy solution warm and also prevent the battery and the electronics inside from freezing. An effective heat conduction system has been implemented for high ambient temperature environments in order to protect the components inside the box from heat.

Space for customer-specific installations and adaptable to the customer`s wishes.

The EFOY ProEnergyBox provides enough space for customer-specififc installations. It can be adapted to the customer’s wishes.

Hybrid compatible

The EFOY ProEnergyBox is hybrid compatible and ideal as back-up or extension for solar energy systems.
