EFOY ProTrailer 4120T and 4130T Mobile, reliable power supply for industrial applications The EFOY ProTrailer: what you need to know • EFOY Fuel Cells are smart energy producers that can continuously and automatically recharge batteries. • They’re based on Direct Methanol Fuel Cell technology, which converts methanol into electricity through a single stage catalytic conversion process. • When a solar array fails to deliver enough power, the EFOY senses the battery voltage drop and automatically switches on to keep the battery bank charged. • Once the battery is recharged, the fuel cell returns to standby mode — no maintenance or user intervention required. • EFOY Pro Fuel Cells have Modbus RTU communications built into the firmware, which allows operators to remotely monitor and control the system and schedule fuel replacements. • EFOY Pro Hybrid solutions deliver 30 – 50% total cost of ownership savings over alternative off-grid technologies. • EFOY Pro Fuel Cells are 10 X more efficient, produce up to 99% fewer emissions and only consume 1 – 2% of the volume of fuel vs fuel gas genset technology Dependable off-grid power is a challenge in any application, but in industries where the landscape constantly shifting, the challenge is even greater. Enter the EFOY ProTrailer — a dependable, self-contained energy solution that delivers 100% reliable power wherever power is required. SFC Energy’s EFOY ProTrailer utilizes patented fuel cell technology combined with solar power to deliver a reliable, autonomous power supply ideal for site surveillance, communication, data logging and other industrial applications. The rugged, purpose-built EFOY ProTrailer integrates the fuel cell in an insulated NEMA 3R -40° C rated enclosure. It includes a vertical mast and fixed solar mounting. EFOY Pro Hybrid systems are designed to provide 12 – 18 months of fuel autonomy, making them ideal for short or long term deployments. Office: +1 403-236-0580 Email: [email protected] www.sfc.com

ProTrailer system design SFC Energy’s EFOY ProTrailers are hybrid power solutions in insulated NEMA 3R enclosures, which house the fuel cell, fuel cartridges, battery bank, solar charge controller and power distribution. Waste heat generated by the EFOY is captured inside the cabinet to keep all the components warm in winter, further improving the efficiency of the system and eliminating the need for a heater.
