Autonomy for telecommunication infrastructures

In areas with good infrastructure, logistics is not a big deal. It does not matter how heavy fuel and canisters are, how much space they take up, or how often a replacement is necessary. The situation is different if a radio relay station can only be reached by helicopter.

Sunfire-Remote meets special requirements in areas that are difficult to reach. The compact devices are the perfect long-term solution – either as a primary power supply or for seasonal use.



Sunfire-Remote offers a perfect tandem with photovoltaic systems. In summer, the solar energy can be harnessed, while fuel cells reliably maintain operations during the dark winter months. Such a hybrid application is not only sustainable, it also extends the maintenance intervals.


Sunfire-Remote is a straightforward off-grid power solution – from installation to maintenance. The system runs on propane or natural gas. Propane is particularly easy to transport and offers an excellent kg per generated kWh ratio – even under consideration of the tank or cylinder weight.


Whether the sun is shining, or it is freezing cold: Sunfire-Remote works reliably year-round – either as a stand-alone solution or in combination with photovoltaics.


For power supply to systems that are difficult to access, Sunfire-Remote is the ideal solution. Long maintenance intervals and remote monitoring enable autonomous operation over a long period of time.

Selected projects

After a successful test phase in winter 2019, we already delivered a double-digit number of Sunfire-Remote units to Alaska. As proven solution to supply off-grid power to microwave radio stations, similar projects with Sunfire-Remote in North America are already in preparation.


Our power generators run up to 10,000 operational hours unattended. This is a world record! That is why the leading U.S. telecom network operator trusts in our fuel cells. Those reliably provide power to several telecommunication facilities in Alaska.

As Sunfire-Remote requires little effort, our equipment is very popular in Alaska, where microwave radio stations are often installed on mountain tops. Those applications can only be reached by helicopter – and only in good weather. Our customers benefit from long service intervals and low fuel consumption.
