Firmware Update
Instruction EFOY/EFOY Pro

Take advantage of our free firmware updates for the new generation of fuel cells, EFOY and EFOY Pro. All you need for an update is an internet connection. You can choose between two different update options.

Note: The SFC Updater is no longer available for the new EFOY generation.

1. option: Firmware Update
with stationary router

  • If your fuel cell is already permanently connected to a stationary router, you do not need to do anything else. Firmware updates will then be applied fully automatically.

  • If your installation does not have a permanent connection to a router connect your fuel cell via LAN cable to a router. As soon as an Internet connection is established, the system checks whether an update is available for your fuel cell. The update will then be stored in the EFOY and connected accessories, such as the control panel or Fuel Manager, will be updated at the same time.

  • The firmware update is installed automatically and starts when the EFOY fuel cell is not in charging mode. The EFOY fuel cell’s LED flashes blue during the update. The firmware update may take several minutes. At the end of the update, the EFOY fuel cell will be in standby and the LED will flash green slowly.

Note: Before updating, please deactivate the EFOY fuel cell’s transport mode via the control panel or the EFOY app. During the update process, make sure that the EFOY fuel cell is connected to the battery and that there is an Internet connection.

2nd option: Firmware Update
via mobile 3G/4G router

  • First power the mobile router and make sure that the router is connected to an available WLAN network and configured. A router recommendation including configuration instructions can be found below.

  • After configuring your mobile router, connect it to the fuel cell via LAN cable.

  • As soon as a connection is established it will automatically check if an update is available for your fuel cell.

  • If a new update is available, the update will automatically be stored in the EFOY fuel cell and connected accessories such as the control panel or the fuel cartridge manager will be updated.

  • The firmware update is installed automatically and starts when the EFOY fuel cell is not in charging mode. The EFOY fuel cell’s LED will flash blue during the update. The firmware update may take several minutes. At the end of the update, the EFOY fuel cell will be in standby and the LED will flash green slowly.

Note: Before updating, please deactivate the EFOY fuel cell’s transport mode via the control panel or the EFOY app. During the update process, make sure that the EFOY fuel cell is connected to the battery and that there is an Internet connection.
