SFC EFOY Fuel Cell Systems — Reliable Hybrid Power for Mission-Critical Applications

SunWize Power & Battery integrates SFC Energy’s EFOY Pro direct-methanol fuel cells into turnkey power systems engineered for long-duration, autonomous operation. Designed to complement solar and wind generation, EFOY systems automatically supply power when renewable sources are insufficient—delivering true year-round reliability with minimal maintenance and long intervals between refueling.

SunWize offers three off-the-shelf EFOY system configurations, each built on a customized SunWize aluminum powder-coated enclosure that houses the fuel cell, full fuel tanks, thermal-control fans, display panel, circuit-protection controls, and wiring harnesses. These configurations are engineered for stand-alone operation or seamless hybrid integration with new or existing solar or wind systems.

Built and tested in SunWize’s U.S. facilities, these systems are optimized for rapid deployment, harsh-environment durability, and operator-free reliability—making them ideal for applications in oil & gas, telecommunications, environmental monitoring, transportation, security / CCTV, and defense.

For OEMs and system integrators, EFOY Pro fuel cells can also be purchased as stand-alone modules for custom integration, enabling scalable hybrid architectures that reduce operating costs, extend maintenance intervals, and ensure power availability when it matters most.

By pairing proven SunWize system engineering with SFC’s market-leading fuel-cell technology, these systems deliver clean, quiet, and dependable energy wherever uptime is critical.
