EFOY Pro 800/2400

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

Intelligent fuel cells, charging batteries fully automatically

Fully automatic power generator

The EFOY Pro 800 and 2400 are the previous models of the new EFOY Pro fuel cells. EFOY Pro 800/2400 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 on automatically, recharges the battery and then returns to standby mode – without any maintenance or user intervention required.

The EFOY Pro 800 and 2400 deliver an output of 45 W and 110 W. Both fuel cells are 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 800/2400 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 which have a continuously low energy consumption for a long duration. The EFOY Pro 2400 is often used for mobile and off-grid surveillance systems as well as ensuring on-board power supply in vehicles.
