Swiss Quality & Safety
Developed and manufactured in Switzerland, our battery storage systems meet the highest safety standards. Rely on durability, reliability, and a 10-year warranty.
Sustainability with Second Life
We give high-quality battery cells a second life. This conserves valuable resources, significantly reduces your carbon footprint, and makes a direct contribution to the circular economy.
Das zweite Leben für Elektro-Auto Batterien.
Anstatt EV-Batterien zu verschrotten, geben wir ihnen ein zweites Leben als stationärer Heimspeicher. Das senkt den ökologischen Fussabdruck und erhöht die Verfügbarkeit. Jede Batteriezelle durchläuft strenge Tests und wird mit dem eigens für Second-Life-Batterien entwickelten modual Batterie-Management-System (BMS) überwacht, damit Sicherheit und Leistung stets garantiert sind.
