Benefits
![]()
Flexible
The Commercial 50 adapts to your requirements – not the other way around. Its hybrid inverter offers additional inputs for generators and an optional backup power supply. This ensures that your operations remain powered even if the grid goes down.

Economical
Energy planning means cost planning. And with the Commercial 50, you reduce your energy expenses exactly where they arise. The system leverages dynamic electricity tariffs and time-variable grid fees to draw power when it is cheapest — handled fully automatically thanks to an intelligent AI-driven schedule.

Secure
100% of the software and all core components are developed and manufactured in Germany. The FENECON servers are also located in Germany. Our inverters are not connected to the internet; instead, they are securely linked to the FEMS Box, which communicates exclusively with FENECON servers. If desired, your system can even operate completely without any internet connection.
Key Facts

FEMS
Energy Storage Systems, inverters & energy management — perfectly aligned and always included.
Its your Energy Journey
Our award-winning OpenEMS-based energy management system FEMS is included with every Energy Storage System. FEMS intelligently controls, monitors, and optimizes your energy flows — operating autonomously without an internet connection if desired, or by default via our secure FENECON servers in Germany. Developed by our teams in Bavaria and, of course, in accordance with the highest data protection standards.
Included
Your storage system contains more than powerful hardware — it also houses the core of your energy management system. FEMS (the FENECON Energy Management System) is not an add-on; it is the intelligent control center that turns your storage system into a complete energy solution.
FEMS is fully integrated from the start: as a compact box inside your storage system and as a high-performance software platform that connects everything. The FEMS Basic Apps for grid-optimized charging and self-consumption optimization form the foundation and are already included free of charge.
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.
1.
Growing With Your needs
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.
2.
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
All our Home models as well as the Commercial 50* are capable of providing backup power. In the event of a power outage, they automatically take over the power supply of the devices in your home or business – reliably and independently of the grid.

All FENECON Home & Commercial models rely on state-of-the-art LFP technology (lithium iron phosphate) – the ideal choice for indoor installations. This cell chemistry is considered exceptionally safe, as it carries virtually no fire risk. At the same time, it impresses with long service life, offering more than 6,000 full charge cycles and ensuring many years of reliable operation. In addition, it is cobalt-free, making it significantly more resource-efficient and environmentally friendly than many other battery technologies.
All models in the Home and Commercial series are not sold directly to end customers by us as the manufacturer, but exclusively through our wholesale partners and international country partners. These partners supply certified installers, who then plan and install the system at your location. Therefore, please request a quote directly from your installer.
You don’t have an installer, wholesaler, or country partner yet? No problem – simply send us an inquiry and we will be happy to connect you with one of our qualified partner companies.
In most cases, an energy storage system pays for itself after around five to eight years – depending on usage and application.
