A remote yard needed a new place for its electrical service, so the team built a small containerized power room. The BigAir 57 solar vent is one of the prototypes in the build. Its job is to keep air moving when sunlight is available, without adding another powered circuit.
Why airflow matters in this build
The container holds equipment that gives off heat. Channing is concerned about warm interior air meeting the cold steel shell, forming frost or condensation that could drip onto the electrical installation. A fan can help move that air, but this video presents the setup as a field trial, not a measured humidity-control result.
A small fan still needs an intake
The vent has a small solar panel and an axial fan that runs when the panel receives sunlight. Without sun, the opening remains a passive vent. The team puts it on the sun-facing side of the container and initially tests whether the factory vents can admit enough replacement air. Channing says they may add dedicated intake vents if those small openings prove insufficient.
That open question is the useful part of the project. Even on a nine-foot container, the exhaust path and the intake path have to be considered together. If you are housing electrical equipment, have the electrical and ventilation arrangement designed for the actual heat load and site conditions.
