Rugged, Purpose-Built Power

The EFOY ProTrailer integrates our EFOY Fuel Cell in an insulated enclosure and includes an extendable vertical mast and a fixed tilt-able solar array that can be pneumatically adjusted from 45° to 70° with an integrated remote.

Solar power alone is weather and season-dependent, and combustion generators are loud, smelly, produce emissions and can cause spills that are detrimental to the environment. Urban deployments demand quiet and clean power solutions, and EFOY Fuel Cells provide silent and clean operation.

EFOY Pro Hybrid solutions are designed to provide up to 12–18 months of fuel autonomy, making them ideal for short or long-term deployments for mobile applications.

Benefits of the EFOY ProTrailer

Reliable power

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 at healthy levels.

Hybridized with solar

Ideal placement of a trailer may mean non-ideal solar availability. An EFOY Pro Fuel Cell enables the system to be placed exactly where it’s needed to perform its job, regardless of shadows from buildings, trees or other obstacles.

Low maintenance

Designed to provide up to 18 months of fuel autonomy, making them ideal for both short and long-term mobile application deployment. After a charge cycle, the fuel cell returns to standby mode — no maintenance or user intervention required.

Remote monitoring

EFOY Pro Fuel Cells can be remotely connected, enabling operators to monitor and control the system without being on site. Remote monitoring is available via Modbus TCP or the EFOY Cloud for EFOY Pro’s 2800.

Mobile power platform for customer equipment

Hybrid solar power with EFOY Pro Fuel Cells ensures the EFOY ProTrailer can be deployed anywhere you can tow it, making it a truly mobile solution.

“Our customer’s decision in favour of the EFOY ProTrailer hybrid solution underlines the value of our technology. It features longer fuel autonomy and provides significant life cycle cost savings compared to conventional systems."
