Microgrid XS – Compact Decentralized Energy System up to 5 kVA
Microgrid XS – Compact Decentralized Energy System up to 5 kVA
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. Photovoltaic-based energy generation 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. Example Economic Scenarios Scenario Annual Energy Use Value / Savings Economic Effect Baseline (Household only) ~6,500 kWh/year ~1,000 – 1,200 € / year Limited economic return + Electric Vehicle Charging Increased self-consumption ~1,500 – 3,000 € / year additional value Strong improvement due to high-value energy substitution + Heat Pump / HVAC Higher local energy utilization Additional system-dependent savings Further optimization of energy self-consumption Key Insight: Economic performance increases significantly when electrical mobility and thermal applications are integrated, as they increase self-consumption and replace higher-cost external energy sources. Not included in the base system Building internal electrical distribution outside the microgrid system Heat pumps, heating or HVAC systems Electric vehicle charging infrastructure Consumer or building technology integration Optional extensions (project-specific) Integration of EV charging stations with intelligent load management Connection of heat pump or HVAC systems Grid-connected system configuration including feed-in management These extensions are not part of the base system and require separate technical design and project planning. The system is based on pre-configured configuration and standardized technical parameters. Dimensioning based on customer-provided information is optional. Once technical planning begins, the system becomes customer-specific. Cancellation after planning start is excluded.

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.

BIM Facility Manager
Task - Work Location: DK - From Ribe
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™.
