KEY USE CASES FOR SOFC

Mobile Solar Power

SOFC provide reliable offgrid power to solar trailers during periods of high load and low solar resource. Enabling greater use of alternative energy.

SOFC Solution

Adaptive Energy offers highly durable SOFC battery chargers that run on propane and offer reliable low-watt power. So solar trailers can power the load during long periods of darkness.

Solar Trailers Must Provide High Uptimes

Critical functions such as surveillance monitoring, remote sensing SoDAR and LiDAR, meteorological towers and more are often powered by mobile solar trailers. 

And especially when deployed to remote areas where maintenance visits are impractical or expensive, these trailers must be able to power the load no matter what.

Low Batteries Can Compromise the Trailer

Batteries keep the equipment running at night, charged by excess energy produced by the solar array during daytime.

But during extended periods of cloud cover, rain or darkness, the solar array can not make enough energy to charge the batteries. This causes them to deplete, putting the trailer at risk of failure.

SOFC Bridge These Downtimes

Enabling the trailer to provide uninterruptible power

Performer Series SOFC compensate for depleted batteries by cycling on to recharge when the voltage dips. They are engineered to integrate easily with renewables like solar to create a hybrid clean energy solution. 

Unlike batteries, SOFC are lightweight and easy to transport. And because propane is more energy-dense than batteries, a 250W SOFC can take the place of some of the required solar panels and/or batteries, so you can use a smaller trailer.

“We’ve worked with Adaptive Energy’s SOFC for several years and give them 10/10 on reliability. In fact we allow system voltages to drop to 23.5 before the fuel cell cycles on to charge the batteries. We did not always trust doing this with a diesel backup system.”

– Paul Woodhouse, CEO at Sentrex Wind Services

How SOFC Integrate With Solar or Wind

When the State of Charge (SOC) of the batteries dips below a preset threshold, the fuel cell automatically cycles on to recharge the batteries. When the upper voltage is reached, the fuel cell returns to standby mode and cools down before powering off. This provides reliable auxiliary power to ensure the trailer can power the load even during times of low sunlight.

Benefits of SOFC for Solar Trailers

The compact, lightweight design creates a product that is easy to transport and has a small footprint. SOFC can reduce the number of solar panels and/or batteries required so you can use an even smaller trailer. Here are other key reasons why customers are using SOFC to bridge downtimes in mobile solar power.

Excel in Extremes

While other technologies like diesel generators or direct methanol fuel cells fail in cold weather, our SOFC are engineered to store, start and operate in temperatures from -40°C to 50°C. They produce no liquid water and are constructed of heat-resistant ceramic tubes that will not freeze.

Highly Reliable

Customers have reported that our SOFC are so reliable that they feel comfortable letting battery voltage drop as low as 23.5 before the SOFC cycles on to recharge.
9

Efficient

With a fuel consumption of .25lb of propane per hour, efficiency is a powerful benefit. A 20-lb propane tank offers 80 hours of runtime, providing plenty of time to schedule a refueling site visit. Plus, propane is cleaner than diesel and more accessible than hydrogen.

9

Fewer Site Visits

Depending on the application, site visits can be as few as one per year, due to the low maintenance needs and high fuel efficiency of SOFC.
9

Engineered to Withstand Vibration Impact

The SOFC undergo rigorous vibration testing to simulate how they might react to being transported in a truck or placed on a trailer. They have been field-proven to withstand a high degree of vibration, making them ideal for mobile power applications.

Remote Monitoring

System performance can be easily monitored from anywhere because SOFC have flexible communications that can integrate with third-party systems.
