EFOY Pro 800 Duo2020-07-23T08:21:29+04:00

EFOY Pro 800

Also available as EFOY Pro 800 Duo with two fuel connectors for even more autonomy

Intelligent fuel cells, charging batteries fully automatically

Fully automatic power generator

EFOY Pro fuel cells are intelligent power generators that can be used to continuously and fully automatically recharge batteries. The fuel cell is connected directly to the battery supplying the consumer and monitoring its charge status. Depending on requirements, the fuel cell switches automatically recharges the battery and then returns to standby mode – without any maintenance or user intervention required.

The EFOY Pro 800 delivers an output of 45 W and is also available as a Duo version with two fuel connectors for two EFOY fuel cartridges. Using the DuoCartSwitch, up to four fuel cartridges can be connected to one EFOY Pro 800 Duo for even more autonomy. Typical areas of application of the EFOY Pro 800 are, for example, measuring stations in the areas of environmental technology that have a continuously low energy consumption for a long duration.

Questions and answers about the
EFOY Pro 800

Why do I need an EFOY Pro fuel cell?2020-07-23T08:22:07+04:00

The EFOY Pro fuel cell is a fully automated battery charger that is quiet, simple and environmentally friendly, operating as a power generator in regions, where no grid connection is available, but a high power demand is needed. In off-grid industrial applications, that are not connected to the grid, the EFOY Pro fuel cell delivers reliable energy, in every weather condition – for security and surveillance, traffic regulation, remote sensors, etc.

How does the EFOY Pro fuel cell work?2020-07-23T08:20:25+04:00

The EFOY Pro fuel cell converts the fuel in the fuel cartridge direct into electrical current. Thanks to this direct conversion, which is performed with no moving parts, silent and environmentally friendly, the fuel cell is extremely efficient, clean and environmentally friendly.

Can I connect electrical appliances direct to the EFOY Pro fuel cell?2020-07-23T08:24:20+04:00

No. The EFOY Pro fuel cell is a battery charger. Electrical appliances are supplied with power by the battery.

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].
