Universal Energy Management for Hybrid Systems

Hybrid energy systems are increasingly becoming the standard in commercial and industrial settings. Combining solar installations, battery storage, heat pumps, and other equipment ensures supply reliability while reducing costs. But reality is often complicated. Those who want to combine components from different manufacturers quickly hit technical limits or fall into the trap of vendor lock-in. What's needed are solutions that are flexible to plan and deliver absolute reliability even in complex environments.

Challenge

Breaking free from isolated solutions

H.E.A.T. set out to create a universal energy management system (EMS) that goes far beyond what conventional residential building solutions can do. The vision was a system that performs equally well in industrial and off-grid applications. The requirements were ambitious:

Manufacturer independence: No binding to single brands or closed systems.
Real-time control: Precise management of all energy flows.
Simplicity: Fast installation and intuitive operation for project managers.

H.E.A.T. specializes in energy management systems and brings over ten years of experience in the energy sector. The team consists of experts from Qinous, the former battery storage specialist now part of Rolls-Royce Power Systems. With this deep expertise, H.E.A.T. develops smart solutions for grid-connected and off-grid battery storage in commercial, industrial, and infrastructure applications. The goal is clear: reduce capital costs, increase profitability, and ensure long-term operational security.

Solution

The result is the H.E.A.T. Energy Gateway – a local energy management system for demanding applications. The software runs on Revolution Pi or other industrial PC platforms and unifies photovoltaics, storage, generators, and EV charging into one system. What makes it special: New devices can be selected and configured directly through the user interface. Complex programming is now a thing of the past.

Why Revolution Pi? H.E.A.T. needed robust, industrial-grade hardware with flexible connectivity options, especially for I/O. Revolution Pi is compact, DIN-rail compatible, and connects up to 20 endpoints directly through expansion modules. This made it the ideal platform for commercial projects where reliability and value for money matter.

A daily performance chart on the right visualizes energy flows, charge/discharge cycles, and optimization targets for real-time energy balance monitoring.

Implementation

The Energy Gateway serves as the intelligent brain of the entire system, continuously re-prioritizing energy flows. Solar power is consistently used first and only curtailed when technically necessary. At the same time, the system intelligently charges and discharges batteries and starts generators only when needed to maximize efficiency. For safety, the control system continuously monitors grid connection limits and reliably prevents overloads.

A decisive advantage is its fully local operation: all core functions run stably even without an internet connection. While weather forecasts or cloud services can be integrated optionally, operational safety remains guaranteed even during internet outages. Through an intuitive web interface, users can manage multiple operating strategies in parallel. The range spans from self-consumption optimization through peak shaving to reduce demand charges to active participation in energy markets.

Technologies Used:

RevPi Connect, modularly expandable with I/O modules
Rust-based protocol servers for security and performance
Connectivity: Modbus TCP/RTU, REST, MQTT, IEC 60870-5-104
Certification to VDE-AR N 4110/4120
Infrastructure: Docker-based deployment for maximum flexibility

"Revolution Pi was the right choice for us – reliable, straightforward to integrate, and performant. The fact that the solution also runs on other platforms provides additional assurance."

Results & Outlook

The H.E.A.T. Energy Gateway is a genuine game-changer for anyone planning and implementing complex energy systems. The benefits at a glance:

40% faster commissioning: Integrated drivers and intuitive configuration eliminate the need for programming.
Future-proof: Systems can be expanded or modernized anytime without overhauling the entire setup.
Extended lifespan: Gentle battery operation and reduced generator runtime.
Lower costs: Less support effort thanks to transparent diagnostics and simple maintenance.
Whether logistics center, production facility, supermarket, or data center, H.E.A.T. delivers a platform that combines profitability with operational reliability, completely free from manufacturer dependencies.
