Blackouts in telecom are a threat to society and the economy. Therefore, a reliable, clean and cost-effective power supply in case of an outage is crucial. Long-term backup power (>7d) could be of interest due to hurricane and extreme weather endangered areas. Sunfire-Remote provides the confidence that power will always be available, even in the most extreme situations. It is perfectly suited for combinations with PV, e.g. for seasonal operation during wintertime.

Together with our partner Ensol Systems, a leading Canadian manufacturer and supplier for off-grid power solutions, we provide Sunfire-Remote units in North America, serving telecom equipment with power during the harsh winters, also at ambient temperatures as low as -40°C
Frequently asked questions
The Sunfire-Remote series is specified currently for operation at ambient temperatures between -20 and +40 °C. With product revisions until summer 2020 an extension to higher temperatures is pursued.
Within a suitable packaging respectively integration that includes ventilation, heat utilisation and thermal management, also deviating temperature ranges are possible, e.g. from -40 to +40 °C.
Fuelled by natural gas with a Methane content of > 90 % OR LPG with a Propane share of > 95 %, Sunfire-Remote provides clean power wherever it is needed.
Sunfire-Remote units are designed for primary and continuous power generation, but not recommended for backup power due to high operation temperatures the heat-up time is several hours and energy demand has to be buffered by batteries during this time. The Sunfire-Remote units could be an option for bridging longer power outage periods depending on fuel reserves.
The Sunfire-Remote systems do not contain any lubricants and only two blowers as components with rotating parts. Hence, the annual proactive maintenance is limited to following activities: visual inspection, cleaning, change of desulfurizer cartridges, gas and air filters, gas leakage test.
The heart of the Sunfire-Remote units are Solid Oxide Fuel Cells (SOFC). These are high temperature fuel cells which operate at temperatures between 800 and 900 °C. Similar to other fuel cell technologies they compose of an anode and a cathode separated by a ceramic electrolyte. This principle is similar to batteries with the difference that fuel cells are continuously fuelled. The ceramic electrolyte conducts oxygen ions from the cathode to the anode whilst electrons are sent to an external circuit in order to produce electricity. At the anode, the oxygen ions combine with the fuel to produce water and carbon dioxide. Heat and carbon dioxide are also generated at the anode. Unlike conventional fuel cells, the Sunfire fuel cells run on hydrocarbons such as natural gas or propane.
