EFOY Pro 12000 Duo

EFOY Pro 12000 Duo providing a higher output.

100% reliable, off-grid energy

Power generator for high energy requirements

The EFOY Pro 12000 Duo, our 500 W fuel cell, offers 100% reliable, off-grid power as well as emergency power. When required, the fuel cell charges the battery fully automatically, then turns itself off again – without maintenance and without user intervention.

Its compact design allows installation in a 19 inch control cabinet. By the output up to 500 W, applications with higher power requirements can easily be operated with the EFOY Pro 12000 Duo. Typical areas of application are back-up power supplies for wind and telecommunications systems, off-grid power supplies for monitoring traffic and environmental sensors as well as on-board use in vehicles.

1) Nominal power varies by ±10 %, decreases with the operation hours. Specification valid within warranty period.

2) Depends on battery type and application – bigger batteries possible, if additional energy source available (e.g. solar)

3) Regional warranty conditions for EFOY Pro fuel cells apply.

4) Factory Setting – can be modified with Interface Adapter and PC or operating panel OP2.

5) Effective consumption depends on operating conditions.

6) At temperatures above +40 °C / +102 °F the power output can decrease. Charging Lithium (LiFePO4) batteries is not always possible at temperatures below 0 °C. The instructions from the battery manufacturer must be observed.

7) During operation above the recommended altitude the power output can decrease.
