The EFOY Pro Series delivers significant logistical and cost-saving advantages over conventional remote power supplies, such as batteries, solar cells and generators. The SFC Inc. system supplies 24/7 maintenance-free, odor-free and quiet off-grid power for a virtually unlimited period of time, as long as there is fuel. The company’s 28-litre M28 methanol fuel cartridge, for example, provides 31.1 kWh of power — enough to operate a concealed, 25-W surveillance camera for more than 50 days without any user intervention. With its integrated set of connectors, the EFOY Pro Series offers maximum installation flexibility and can be easily included in any customer application. The fuel cells’ robust casing and construction can withstand the roughest environmental conditions
