Summary
| Max. load (device) | W |
| Energy demand per day | Wh / day |
| Average output | W |
| Battery voltage | V |
| Location | |
| Operating hours per year and per device | hours |
| Methanol consumption per year | liter |
| Recommended EFOY Pro fuel cell | |
The daily energy demand you have specified cannot be covered by the EFOY alone. Hybrid operation with another energy source such as solar is required. If you have any questions, please feel free to contact us. Contact | |
Please note that the power requirements of your equipment may increase at high or low outdoor temperatures, due to additional components requiring active ventilation or heating. | |
Required components
Additional components are required to operate the EFOY/EFOY Pro Fuel Cells. For detailed information, please contact us, we will be happy to advise you.
Optional components
We offer additional optional components for operating the EFOY/EFOY Pro Fuel Cells. For detailed information, please contact us. We will be happy to advise you.

| Fuel Tank MT60 | days | days | days |
The shown values are average values for one year. The real autonomous runtime depends on season and may vary because of antifreeze mode as well as start/shut-down phases of EFOY Pro where not the full power output is generated. | |||
Operating hours per year and per device
| Device name | Amount | Operating Hours |
|---|---|---|
| EFOY 80 | hours | |
| EFOY 150 | hours | |
| EFOY Pro 900 | hours | |
| EFOY Pro 1800 | hours | |
| EFOY Pro 2800 | hours | |
| EFOY Pro 12000 (Duo) | hours | |
Average values; actual yearly number of operating hours can vary depending on age of EFOY Pro unit | ||

Disclaimer
SFC Energy AG takes no responsibility for correctness of this calculation. The values generated by the energy calculator are estimates under ideal conditions only and should not be taken as formal quotes. The real energy yield from solar panel can depend on further factors like inclination, alignment and fouling of solar panels as well as shading due to buildings, trees, etc..
Daily requirement too high, no recommendation possible
Your information on the daily requirement is too high. Currently no recommendation is possible. Please contact us if you have any further questions or if you would like individual advice on your project.
You do not need a power supply
Please check your entry. With the given values you have enough power available. A recommendation is not possible.
