Off-grid power should not cause you bad sleep

Off-grid power with Sunfire-Remote is simple, space-saving and involves little effort. It is the ideal solution for secluded areas, operating reliably either as a stand-alone energy source or in combination with photovoltaic systems.

  • Be independent: Maintenance intervals > 1 year enable autonomous operation.
  • Think ahead: Thanks to high fuel cell lifetime you benefit from a long-term solution.
  • Rely on robustness: Your power generator operates continuously – also under harsh conditions.
  • Enjoy simplicity: Sunfire-Remote will be easily installed and integrated with your system.
  • Care for the environment: You choose a sustainable alternative to conventional technologies.


Benefit from an innovative technology

With hundreds of systems installed, Sunfire is a global industry leader in the award-winning Solid Oxide Fuel Cells (SOFC) technology. Our stacks, the core of our fuel cell devices, operate at temperatures between 750 and 850 °C. They convert propane and natural gas electrochemically into electricity and heat.

Process of fuel cell technology
  • Reliability: Sunfire stacks have demonstrated up to 30,000 operational hours (opHrs) in continuous operation
  • Robustness: Full performance in a temperature range between –20 and +55 °C, extension to -40 °C possible
  • Low operating costs: Long maintenance intervals and low consumption of common fuel
  • Multi-fuel: Available for the use of natural gas or propane – also from renewable sources

Power from 50 Watts to multiple Kilowatts

Sunfire-Remote is as individual as your challenges. Choose between two generators: Either as single unit or many combined to a larger system to achieve higher power output.

Renewable energy with Sunfire-Remote
Ready for renewables

Our customers use natural gas or propane to fuel Sunfire-Remote, substantially cutting CO2 emissions compared to conventional diesel generators. As our power generators convince with an unrivaled efficiency, they consume correspondingly little fuel. This, too, has a positive effect on the carbon footprint.

And there is even more reduction potential: Fuel your Sunfire-Remote with propane or natural gas from renewable sources and turn your off-grid power supply carbon-neutral.

Increasing mobility and freight requirements are placing ever more complex demands on our rail infrastructure. With Sunfire-Remote, we reliably ensure the power supply of monitoring and radio systems.

Managing Director Furtenbach Adventures GmbH

Our customers are used to nothing but success. Even on the highest peaks on earth. To set new standards in high attitude climbing, we invest in the latest technological developments. Not only the idea of using clean electricity for a medical sauna at the base camp of Mount Everest goes with our nature. But also that robust and reliable power source. The best thing about Sunfire-Remote: It works with customary camping gas from the market in Kathmandu.
