The EFOY Pro 12000 Duo, our most powerful fuel cell, offers completely reliable, off-grid and emergency power. With a power output up to 500 W, the EFOY Pro 12000 Duo operates applications with higher power requirements and it fits within a control cabinet that’s just 19-inches across. Typical areas of application are back-up power supplies for wind and telecommunications systems, larger multi-wellpad SCADA and measurement systems, off-grid power supplies for traffic monitoring and environmental sensors and 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.
