EFOY Pro 2400 Duo2020-07-23T08:49:13+04:00

EFOY Pro 2400

Also available as EFOY Pro 2400 Duo with two fuel connectors for even more autonomy.

Reliable power supply based on mobile energy solutions

Fully automatic & off-grid power supply

EFOY Pro fuel cells charge consumer batteries fully automatically and constantly monitor their charge status. Depending on requirements, the fuel cell switches on automatically recharges the battery and then returns to standby mode – without any maintenance or user intervention required.

Up to four fuel cartridges can be connected to one EFOY Pro 2400 Duo fuel cell using the DuoCartSwitch. The EFOY Pro 2400 delivers an output of 110 W and is also available as a Duo version with two fuel connectors for even more autonomy. Typical areas of application of the EFOY Pro 2400 are the operation of mobile and off-grid surveillance systems as well as ensuring on-board power supply 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.

EFOY energy solutions

EFOY Pro energy solutions combine power generation via EFOY Pro fuel cells and energy storage with batteries in suitable housing. There is still sufficient space for customer-specific adaptations.

Quiet and environmentally friendly

Thanks to environmentally friendly power generation, the EFOY Pro can be used in nature reserves as well as in closed vehicles and rooms.

Questions and answers about the
EFOY Pro 800

Is there a risk that the batteries can be exhaustively discharged?2020-07-23T08:36:50+04:00

No. An EFOY Pro fuel cell is programmed to prevent exhaustive discharge and will activate even when switched “OFF” in order to protect batteries from exhaustive discharge. An additional deep discharge protection has to be installed independently.

Can an EFOY Pro fuel cell also be monitored?2020-07-23T08:38:04+04:00

Yes, remote monitoring is possible with a modem. Please contact our partners or send an email to [email protected].

What is the EFOY Pro fuel cell designed for?2020-07-23T08:45:24+04:00

The EFOY Pro fuel cell has been designed and developed for commercial and professional operation.
