Remote Monitoring

The EFOY Pro fuel cell can be monitored and controlled via modem.

100% reliable off-grid power

Power generator for high energy demand

The EFOY Pro 12000 Duo, our 500 W fuel cell, offers 100% reliable off-grid power and backup power. The fuel cell fully automatically recharges the battery if necessary and then switches itself off again - maintenance-free and without user intervention.

The compact design allows installation in a 19 inch cabinet. With an output power of up to 500 W, applications with higher power requirements can easily be covered with the EFOY Pro 12000 Duo. Typical applications include backup power for wind and telecom systems, off-grid power for traffic monitoring and environmental sensors, and on-board vehicle integration.


For which applications are EFOY fuel cells designed?

The EFOY direct methanol fuel cells are available as EFOY and EFOY Pro models with an output of up to 500 W, depending on the power requirement and usage requirements.


Our EFOY and EFOY Pro models are designed for different purposes. The EFOY models are designed for temporary use with few operating hours and are used as a back-up power supply for grid-connected or solar-powered hybrid installations. The EFOY Pro series is ideal for continuous operation and can also be used in hybrid operation. With the EFOY Pro, you can operate your application completely independently, compensate for low solar power and use smaller solar modules.


The hydrogen fuel cell solution EFOY Hydrogen serves as a back-up power supply solution and is ideally suited for providing clean emergency power and off-grid applications instead of a conventional generator, e.g. in the following markets:

  • For almost all stationary and semi-mobile applications up to 10 kW

  • UPS (Uninterruptible Power Supply)

  • Backup Power Supply – Telecom/IT/Data Centers/Hospitals

  • Railway and transport control / substations

  • critical infrastructure

  • Energy, gas or water supply

The EFOY Pro and EFOY Hydrogen fuel cells have been developed and designed for commercial and professional use.

What do I have to consider during installation?


When selecting the installation space, make sure that there is sufficient supply air and that the waste heat/exhaust air is dissipated. Please also check whether there is enough space for the fuel cartridge and the device. Please refer to the operating instructions for further information.
