Optional accessories for EFOY & EFOY Pro

The right accessories for your fuel cell

There are various, optional accessories for your EFOY & EFOY Pro fuel cell.¹ Operate the EFOY on site via a control panel or remotely from your laptop, smartphone or tablet. The EFOY accessories allow you to monitor your fuel cells around the clock, to incorporate them into an existing communication network and extend the self sufficiency of your systems.

Remote monitoring with EFOY Cloud

EFOY fuel cells are often used in remote locations and require the option of secure remote access. EFOY Cloud gives you access to your methanol fuel cells from anywhere so you can monitor continuous operation via laptop, tablet or smartphone. All you need for this is an Internet connection to your fuel cells.

You can, for example, track the current operating status of each of your fuel cells, historical data or fill levels of the EFOY fuel cartridges. If necessary, configure battery parameters and receive the firmware updates completely automatically. The integrated alarm management informs you, for example, by email of upcoming fuel cartridge replacements or a battery voltage that falls below the threshold.
