Benefits
Flexible
Thanks to the open FENECON Open EMS platform, you are not tied to any single manufacturer — whether for inverters or other components. Your system remains expandable, adaptable, and grows flexibly with your requirements.
Economical
By reading the energy flows, you can see when surplus energy is being efficiently converted into heat and how the temperature in your heat storage tank increases. This added transparency enables informed decisions to optimise your heat generation and sustainably increase the efficiency of your system.
Sustainable
The app contributes to resource optimisation by providing insights into heat production from your self-generated energy. This helps you use renewable electricity effectively and avoid energy losses from unused surplus.
Key Facts
01
More Transparency
You can see at any time when and how much of your surplus PV energy is being converted into heat — giving you better insight and enabling targeted optimisation of your energy flows.
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.

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.

FAQ
The app is currently compatible with all common models of the FENECON Home-,Commercial- & Industrial series.
For FEMS Extension Apps, please contact the specialist partner or installer from whom you purchased your storage system for pricing and ordering information.
Our home and commercial storage systems are sold exclusively through wholesalers and certified specialist partners.
In general, FENECON can integrate all common multi-stage immersion heaters into the energy management system. However, you also have the option to order a suitable immersion heater (3 kW or 6 kW) directly from FENECON.
