The EFOY Pro 12000 Duo, our 500 W fuel cell, delivers 100% reliable off-grid, on-board and back-up
power. Its compact design makes it ideal for installation in a 19″ control cabinet. By connecting
multiple modules, higher outputs are also available. Through the increased output to 500 W, the
EFOY Pro 12000 Duo can also be used for applications with higher power requirements. Typical areas
of application include back-up power supplies for wind and telecommunications systems, off-grid
power supplies for monitoring, traffic management and environmental sensors and the on-board
power supply of service and control vehicles.
