Growing With You
Your life changes – and your energy system grows with it. Thanks to FEMS, your storage system remains open for anything the future brings: new devices, new ideas, new possibilities. And all of this without lock-in, without subscriptions, without artificial limitations. Instead, you get lifelong, free updates that keep your system always up to date.
Through optional, one-time purchasable FEMS Extension Apps, you can expand your system at any time – for example with charging stations, heating rods, or other consumers. This turns your storage into a customized energy system that perfectly fits your everyday life – not something off the shelf. Thanks to the manufacturer-independent open-source approach, you remain completely free in choosing your components. FEMS grows with you – because true independence only works when systems stay open.

Thinking Ahead
FEMS ensures that your energy doesn’t just “run” – it adapts to your life. It acts intelligently, proactively and independently. Using AI-based forecasting, FEMS creates a holistic, customised energy plan for your needs, updating it every minute and incorporating all relevant factors.
FEMS analyses weather data, consumption profiles, tariffs and grid conditions in real time and makes forward-looking decisions that intelligently control your energy flows. The result: you save costs, conserve resources and reduce strain on the power grid at the same time.
