No matter the situation, Sunfire-Remote can be trusted to deliver clean, reliable and cost-effective off-grid power to your project. Only one annual proactive maintenance and the use of robust long-life industrial components keep costs down.
Sunfire-Remote
Energy conversion at its best
Sunfire-Remote’s modular nature together with it`s industry leading performance and reliability makes it well suited to serve a wide range of industries. Sunfire-Remote operates in the harshest environments – bringing highly autonomous operation and low maintenance together in a robust design. It boasts an electrical efficiency of up to 35 %, almost double that of traditional diesel or gas generators, leading to emission and cost savings.
Our technology offers unmatched flexibility, working with Propane (LPG) or natural gas; while not emitting any significant pollutants. Few moving parts are leading to a long lifetime, and a reduced need for regular maintenance. This makes Sunfire-Remote perfectly suited for use in hard to reach locations.
Sunfire-Remote 400
Our compact Sunfire-Remote 400 unit is perfectly suited for stationary or semi-mobile applications. Easy to integrate due to small size and low weight.
Small but powerful.
Sunfire-Remote 900
Stationary off-grid applications with higher power needs can be supplied safely with our Sunfire-Remote 900. Heat can be utilised optionally for heating additional equipment by reaching highest total efficiency.
Energy for any situation.

Frequently asked questions
How high is the fuel consumption? How long does a full tank last?
Sunfire-Remote fuel cell units have an electrical efficiency of approx. 30 %. As a rule of thumb, there is a need of 3.33 kWhchem from fuel for 1 kWhel and 12.9 kWh chemical energy is stored in 1 kg Propane. Hence, about 3.87 kWhel can be generated from 1 kg Propane.
For a detailed fuel calculation a load curve, including voltage levels and peak power information is required to consider battery changing and conversion equipment efficiencies.
Are Sunfire-Remote fuel cells noisy?
No, they operate with low noise and without vibration. Noise mainly occurs from fans as well as a burner during start-up, optional additional noise adsorber are available.
What is the maintenance effort for Sunfire-Remote?
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.
How does the Sunfire fuel cell work?
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.
