The Application

Base transceiver stations (BTS) are often situated in locations difficult to access. They require reliable backup power in case of power outage in order to assure the availability of public communication systems.

Power demand between 500 and 800 W
Autonomy demand 3 to 5 days for backup power

The Challenge

Provide reliable backup power with an energy solution that is easily handled and requires hardly any maintenance.

The Solution

Cluster up to 8 EFOY Pro fuel cells and hybridize these with batteries.

The Benefits

  • Increased runtime and autonomy: Autonomy for up to 5 days with enough time to resolve the power outage problem.
  • Lightweight: EFOY Pro fuel cells are lightweight. This eliminates the need of keeping large and heavy batteries (up to 2.5 t per transceiver station) for emergencies, easing installation and handling processes.
  • Easily installed and handled: An EFOY Pro fuel cell is compact and lightweight and can easily be integrated into existing cabinets. Once installed the only service that is needed from time to time is a cartridge exchange, which the fuel cell will communicate way ahead; EFOY Pro can be remote controlled, making extra trips to the site unnecessary.

EFOY Pro supplies reliable off-grid power at remote sites while reducing logistics costs
