Sunfire-Remote replaces inefficient generators
Microwave radio stations ensure that even the most remote areas of Alaska are covered with telephone and broadband internet services. In the past, problems with the power supply of these applications arose. Thermoelectric generators repeatedly have proven inefficient, while fuel cells did not always work reliably. Therefore, in 2019, the leading U.S. network operator went for a long-term solution with Sunfire-Remote.
Challenge
- Station can only be reached by helicopter
- Limited accessibility in wintertime
- Harsh climate with frequent weather changes
- Temperatures from -30 to + 35 °C
- High humidity
Customer
-
Leading U.S. telecom network operator

Powerful symbiosis of fuel cells and photovoltaics
Sunfire has already delivered a double-digit number of Sunfire-Remote units for supply of microwave radio stations in Alaska with power during the winter. In addition, photovoltaic systems provide the necessary energy in summer. That solution is not only environmentally friendly. The effective combination of power generators also extends the lifetime of the fuel cells.
Benefits
- Remote control and monitoring
- Less service flights
- Simple commissioning and operation
- Efficient power generation
- Reduced fuel consumption
