Flexible into the future
Future-proof
The hybrid inverter offers additional inputs for generators and an optional emergency power supply, so your business stays supplied even in the event of a power failure.
Economical
The storage charges when electricity is cheap and supplies when it gets expensive. This way you benefit from dynamic electricity tariffs and time-variable grid fees - fully automatically thanks to the intelligent AI-based energy roadmap.
Secure
100 % of the software and key components are developed and produced in Germany, and the FENECON servers are located in Germany as well. The inverters are not connected to the internet, and the system can also run without an internet connection.
FEMS energy management - smart, growing, thinking
Included
The FEMS (FENECON Energy Management System) is not extra software – it is the control centre that turns your storage into a complete energy system. It is built in from the start, and the basic apps for grid-optimized charging and self-consumption optimization are included free of charge.
Monitor your energy at any time in the browser or in the app (Android & iOS) with live data, clear analyses and a locally stored history.
Growing
Your life changes, and your energy system changes with it. FEMS stays open to new devices – with no subscription, no artificial limits and free lifetime updates.
With optional one-off FEMS extension apps you can add wallboxes, heating elements or other consumers at any time, and stay free in your choice of components thanks to the open-source approach.
Thinking
FEMS creates a holistic, tailored energy roadmap every minute using AI-based forecasts. It analyses weather data, consumption profiles, tariffs and grid conditions in real time and makes predictive decisions.
The result: you save costs, conserve resources and relieve the power grid at the same time.
