🔋 Store energy and use it flexibly over time
⚡ Intelligent energy management within the system
🔌 Optional integration of additional consumers within the project context
🎯 Which system size fits your energy demand?
XS – up to approx. 5 kVA S – up to approx. 8 kVA M – up to approx. 15 kVA L – up to approx. 30 kVA XL – up to approx. 45 kVA
Start with preconfigured microgrid solutions for typical commercial and industrial applications.
These systems combine energy generation, storage and intelligent control into a ready-to-use infrastructure.
Ideal for companies that want to quickly reduce energy costs and increase independence.
The Microgrid XS is a modular decentralized energy infrastructure system for the generation, storage and conversion of electrical energy in buildings and distributed sites.
It forms a technically coordinated unit consisting of photovoltaic generation, battery storage and power conversion.
The system is designed for a maximum connection capacity of up to 5 kVA and optimized for stable low-load operation.
It is further designed for repeatable deployment across multiple sites and integration into larger distributed energy portfolios.
Depending on project-specific design, the microgrid system can be configured as an off-grid system (autonomous supply) or as a grid-connected energy system with optional feed-in capability.
Pre-configured System Architecture
The system is based on a pre-configured power conversion unit (PCU), allowing for reduced on-site installation time, improved system reliability and consistent system performance.
Core power electronics, protection components and control systems are pre-assembled, tested and configured prior to delivery, reducing on-site wiring and commissioning effort. Modular battery integration enables flexible storage configurations depending on project requirements. The system is not limited to energy generation, but provides an integrated solution for energy conversion, storage and controlled power supply.

Battery storage system for energy storage and load optimization
Power conversion and system control (hybrid inverter / energy management system)
Core components within the defined system boundary (up to 5 kVA)
Economic Characteristics
Economic performance depends on site conditions, load profile and system configuration, with strongest benefits in high-cost energy environments, diesel replacement scenarios and applications requiring reliable energy supply.

Right of Withdrawal (EU Consumers)
Consumers have the statutory right of withdrawal in accordance with applicable consumer protection laws.
Early Expiry of the Right of Withdrawal:
The right of withdrawal may expire prematurely if the customer expressly requests that the service begins before the end of the withdrawal period and acknowledges that the right of withdrawal is lost once the service has been fully performed.
Individually Configured Systems:
For system components that are individually configured, pre-assembled, or tailored to customer specifications, the right of withdrawal may be excluded where legally permitted.
Project Scheduling:
Installation dates are scheduled after order confirmation within a defined execution window. If performance cannot be carried out due to reasons attributable to the customer (e.g. lack of access or missing prerequisites), additional costs may apply.
This structured approach ensures a transparent, efficient, and technically compliant installation with clearly defined responsibilities and cost allocation.

🧠 Step 3: Custom Microgrid
For complex requirements, we develop tailored energy systems aligned with your location, load profiles and economic goals.
The modern BIM Facility Manager, like a "caretaker", ensures environmentally friendly operation of the building and technology.
The advantages with BIM Facility Manager
Technology and buildings are organized economically, including operator obligations. This ensures repairs, maintenance and the organized deployment of specialists. External contracts with BIM-CAFM are monitored according to generally accepted technical standards. BIM Facility Management knows more than just mechanics, fire protection, construction technology, MSR or refrigeration technology.
How BIM Facility Managers work with buildings
In general, every building needs a 3D model and, if necessary, it will be created for you. This is the basis for the climate-neutral concept for building management. Additionally, a digital platform for BIM-CAFM will be mandatory, which you can obtain through our BIM Manager.
Where maintenance contracts are offered
This can be found under the category BIMcare™.
Always fully configure supply chains
The best is a 4 days / week from Monday to Thursday. This is not an all-in, travel costs and work equipment are not included which you may find under the catgeories BIMpilot™ or BIMphases™.
