The EFOY Pro 2800 utilizes DMFC (Direct Methanol Fuel Cell) technology, providing continuous power generation with low noise and minimal maintenance — ideal for long-term, stable power supply needs in telecom base stations, remote monitoring, and unmanned equipment.
In remote locations where energy is unreliable, power outages mean more than just equipment downtime — they translate to costly data loss and expensive emergency repairs. As the flagship model of the Pro series, the EFOY Pro 2800 is purpose-built to tackle power challenges in high-load and harsh environments. It's not just the ideal backup for solar power — it's the key piece to achieving unmanned operation management.
EFOY Pro not only helps reduce particulate emissions through its eco-friendly
24/7 battery status monitoring with automatic charging activation. Automatically switches to standby mode once charging is complete — no manual intervention required.
Supports connecting 2 to 8 fuel cartridges. Automatically switches to the next cartridge when one is depleted, ensuring weeks to months of uninterrupted power supply.
Ultra-quiet operation with low vibration and no heat generation. Produces only minimal CO₂ and water, making it suitable for use in nature reserves and enclosed spaces.
Fuel cartridge replacement is quick and simple — even untrained personnel can operate it with ease, significantly reducing maintenance costs.
Equipped with Bluetooth or control panel, allowing real-time monitoring of fuel cell status and methanol levels via the EFOY App or cloud platform.
Unaffected by weather or season, delivering stable power in any environment — the perfect complement to solar panels.
Application Scenarios
Where the grid cannot reach, DMFC can be deployed. Using methanol as fuel, it operates automatically 24/7, unaffected by weather or seasons, ensuring continuous and stable operation for equipment in remote locations.
Base stations in remote or mountainous areas face grid access challenges, while traditional diesel generators require frequent refueling and maintenance. DMFC can connect 2 to 8 methanol fuel cartridges with automatic switching, allowing weeks to months of autonomous operation without human intervention, ensuring year-round stable communication.
For long-term deployment in non-electrified areas such as hydrological stations, oil and gas pipeline sensors, and environmental monitoring equipment. DMFC provides stable DC power, and with the EFOY App, users can remotely monitor fuel status, eliminating the need for on-site management.
UAV ground stations, geological surveys, or military field missions require long-term power in grid-free environments. DMFC is compact, vibration-free, and nearly silent. It can be integrated into mobile vehicles or outdoor equipment boxes without revealing its location or affecting equipment precision.
Solar systems cannot generate power during rain or at night; traditionally, this required oversized battery banks. As an intelligent backup for solar, DMFC automatically starts charging when battery levels are low and enters standby mode when sunlight is sufficient, significantly reducing battery capacity requirements and costs.

Help & Support
We have compiled the most frequently asked questions from our clients. If you can’t find the answer you’re looking for, please feel free to contact our team directly.
DMFC (Direct Methanol Fuel Cell) features no engine or vibration with ultra-low noise (<48 dB). It provides continuous power by simply refilling methanol, unlike lithium batteries with capacity limits or diesel generators that require frequent maintenance. It is the ideal solution for long-term unmanned sites.
Supports 2 to 8 fuel cartridges simultaneously with automatic switching, enabling weeks to months of uninterrupted power. Refueling is as simple as swapping cartridges—no specialized technical staff required.
Perfect for telecom base stations, remote monitoring, UAV ground stations, field exploration, emergency disaster relief, and any area with unstable or no grid coverage.
Yes. With an operating range of -20°C to +50°C, it runs stably under various climatic conditions, remaining unaffected by extreme weather or seasonal changes.
Yes. The system features an automatic protection mechanism. Status can be monitored in real-time via the EFOY App or cloud platform. In case of anomalies, the system automatically triggers an alert and switches to standby mode.
Methanol is a flammable liquid. It must be stored away from ignition sources in a well-ventilated area. Transport must comply with hazardous goods regulations. We recommend referring to the technical documentation or contacting us for specific guidelines.
Yes. EFOY Pro 2800 can serve as a backup power source for solar systems, automatically starting to charge when sunlight is insufficient. It is an ideal hybrid solution.
The system automatically monitors battery status and starts as needed without manual intervention. The entire process is automated, providing stable power immediately after startup.
Routine maintenance primarily involves swapping fuel cartridges, which is simple and requires no specialized tools. Designed for zero-maintenance, it does not require regular factory servicing under normal use.
The main consumables are methanol fuel cartridges and the fuel cell stack. System output is 105W after 3,000 hours and 87W after 6,000 hours. Actual lifespan depends on usage frequency.
EFOY Pro 2800 outputs 12V or 24V DC, primarily for battery charging. To connect AC devices, an inverter is required. We recommend confirming power requirements before purchase.
Yes. Equipped with Bluetooth and a control panel, the system allows real-time monitoring of fuel cell status and methanol levels via the EFOY App or cloud platform. It provides early alerts when fuel is low.
The EFOY Pro 2800 is specifically designed for long-term, automated stationary applications. While compact enough for mobile integration, its core advantage is providing months of uninterrupted power without human intervention.
The EFOY series has an extensive track record in military, disaster relief, and field exploration applications worldwide.
It produces only small amounts of CO2 and water, with no noticeable exhaust or odors. It is safe for use in nature reserves and well-ventilated enclosed spaces. For indoor use, basic ventilation is recommended.
