Humanity is finally saying goodbye to energy production through oil, gas, coal or nuclear fusion towards renewable energy through wind, water and sun. This energy transition is THE mega trend of our time! The main challenges are the rapid growth of electromobility and the increasing power demand for heating and cooling of buildings. Renewable energy generation, however, is characterized by a degree of volatility, or fluctuations. We take up these challenges with our neoom battery storage and e-mobility charging solutions. With an innovative energy storage system, every private and commercial user can provide local energy in a cost-effective, safe and above all clean manner and react to the flexibility of the market. Our neoom hardware products are unique in design, functionality and quality. Our intuitive, open and device-independent NTUITIY software is the missing link in energy management. Renewable energy can be stored and consumed by our solutions with maximum efficiency. And best of all, we can deliver today! Take the first step in a sustainable life, visit our website, call us and connect now to neoom.
