Empowering Renewable Energy with Flexible Switchgear Solutions
The energy transition requires solutions that deliver immediate results: Greiner switch cabinets offer you a genuine, cost-effective alternative to conventional concrete substations. Shorter delivery times, lower overall project costs, and the elimination of concrete make our outdoor low-voltage distribution cabinets a practical choice for operators of photovoltaic systems, battery storage systems, and charging infrastructure—without compromising on safety or grid compliance. Our outdoor cabinets are designed to be quickly commissioned, expanded as needed, and adapted to different operator or utility company specifications. Whether expanding a fully utilized concrete substation, directly connecting a new PV area to the grid, or creating modular wallbox distribution systems, Greiner delivers turnkey, durable solutions from its own production facilities—practically oriented and ready for use.
Tailor-Made Solutions – Your Advantages at a Glance
- A genuine alternative to the concrete station.
Our outdoor NSHV replaces the traditional concrete station where rapid availability, lower costs, or limited construction space are crucial. The modular design significantly reduces planning and construction effort. - Shorter delivery times, lower project costs. Prefabrication in our production facilities reduces on-site assembly time and minimizes coordination with construction work (e.g., foundations, concrete work). This has a direct impact on schedules and overall costs.
- Sustainable use of materials
By avoiding concrete, you reduce the material consumption and the project’s CO₂ footprint — a direct contribution to sustainable project implementation. - Expandable and multifunctional:
Our cabinets can be used as outdoor extensions when the low-voltage distribution board in a concrete substation is fully occupied. They can also be used as wallbox distributors , distributors for battery storage, or as additional feed-in/output stations.
Technical Standards That Guarantee Project Success
Meeting technical standards is not an end in itself: For you, it primarily means smooth approval processes, less coordination effort with the grid operator, and significantly faster commissioning – ultimately saving you money. At the same time, you benefit from a durable, low-maintenance system that runs reliably in continuous operation – even under harsh outdoor conditions.
To ensure you benefit without compromise, our sophisticated and flexible production process is consistently geared to meeting all relevant standards and customer requirements:
Konstruktion und Anschlusskonzepte entsprechen den relevanten Anschlussrichtlinien VDE-AR-N 4105 und VDE-AR-N 4110; die genaue Ausführung und Detailanpassung realisieren wir komplett flexibel nach Kunden- und EVU-Vorgaben.
Wetterfeste, abschließbare Gehäuse mit geeigneter Schutzart, korrosionsgeschützte Oberflächen und durchdachte Kabeldurchführungen sorgen für langlebigen Betrieb im Außenbereich.
Flexible Feldaufteilung für Zähl-, Schalt- und Schutzeinbauten; einfache Erweiterbarkeit vor Ort ohne größere Umbauarbeiten.
Vorkonfigurierte Optionspakete reduzieren Inbetriebnahmezeiten. Schnittstellen für Monitoring, Grenzleistungsüberwachung oder EVU-Schnittstellen können kundenspezifisch vorbereitet werden.
The design and connection concepts comply with the relevant connection guidelines VDE-AR-N 4105 and VDE-AR-N 4110 ; we implement the precise design and detailed adaptation completely flexibly according to customer and utility company specifications.
