Yotta Energies, a clean energy startup based out of Austin, Texas, has been making waves in the solar field since its founding in 2017. Its newest product, which was launched in September 2022, is seeking to provide off-grid charging for electric vehicles across the US. This product, the Yotta REV, is a deployable EV charger that is entirely powered by solar. These rapidly deployable chargers can be installed in 48 hours, use bifacial solar modules, and are grid optional. The REV is designed for year-round use and in all weather climates. Shipped in a standard shipping container, it has a vast amount of potential for deployment overseas in areas that experience large-scale power outages (that likely means South Africa).
This is not a high volume EV charger for busy rooutes though. It can be used as a power generation facility during natural disasters or grid outages, giving it a variety of uses for municipalities and emergency services. Groups that work in remote locations, such as wildland firefighters, miners, construction workers, and researchers, are all among potential users. Particularly for large parks with off-grid campsites, having a reliable and durable charging station will increase park visits.
