Our roots in Greenville, South Carolina
Made for America, built in South Carolina. FENECON USA began in a Greenville-area workshop with a small group of engineers and technicians and a big goal: bring German-engineered energy storage to American businesses, built right here in the Upstate. Today our office and production facility are ready, our team is growing every day, and series production is about to begin. We’re building more than batteries. We’re building a crew, a facility, and a future in South Carolina, and we’re just getting started.
