phase accurate
peak shaving
The FEMS App Phase-Accurate Peak Shaving not only regulates the total power at the grid connection point, but also monitors and limits each individual phase in real time. This prevents single-phase peak loads — for example, during charging processes — even when the total power is still within the defined limit.
The FEMS App Phase-Accurate Peak Shaving not only regulates the total power at the grid connection point, but also monitors and limits each individual phase in real time. This prevents single-phase peak loads — for example, during charging processes — even when the total power is still within the defined limit.
Benefits
Flexible
The FEMS App enables the expansion of an existing grid connection point without the need to upgrade transformers or cabling — ideal for operating even large consumers or entire charging parks reliably on small grid connections.
Economical
Unlike classical peak shaving, the phase-accurate variant specifically prevents phase overloads and shutdowns. This reliably avoids expensive peak loads and operational interruptions — ideal for charging infrastructure and commercial applications. As a result, economic efficiency increases and payback times for the storage solution are significantly reduced.
Sustainable
By smoothing peak loads, your storage system helps balance energy flows in the grid. This ensures stable grid conditions and reduces stress caused by disruptive peak loads. This in turn supports the energy transition.
Key Facts
01
Precise Phase Control
Monitors and controls each individual phase separately — for maximum grid stability, cost reliability, and protection against overload.
02
One-time purchase instead of a subscription
No hidden-cost subscription model: you purchase the FEMS App once and use it permanently without any ongoing costs.
03
Lifetime Free Updates & Support
Benefit from continuous improvements and personal support — directly from our developers and service staff in Germany.

FEMS
Energy Storage System, inverter and energy management — perfectly matched and always included.
Its your Energy Journey
Our award-winning Open-EMS energy management system FEMS is included with every Energy Storage System. FEMS intelligently controls, monitors and optimises your energy flows – autonomously without an internet connection if desired, or by default via our secure FENECON servers in Germany. Developed by teams in Bavaria – naturally according to the highest data protection standards.
Included
Via online monitoring in your browser or through the app (Android & iOS), you can keep an eye on your energy at any time. Live data, clear analytics, and locally stored history provide full transparency. Your data is always protected through cyber security by design, German-based servers, and a development team located in Germany — naturally in accordance with German data protection and IT security standards.

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.

"Previously, only the total power was limited — now the system controls each phase individually. Since then, we haven’t had any tripped fuses, and our charging points run reliably and cost-efficiently."
