About us
With a focus on quality, flexibility, and sustainability, we develop and manufacture customized systems for power distribution and building automation. Customers worldwide rely on Greiner’s innovation, expertise, and over 70 years of experience—from renewable energy plants to industrial applications.
What makes us special
Our solutions are used across industries, especially in outdoor installations. They operate reliably, e.g. as low-voltage main distribution boards in solar parks, supporting efficient energy supply.
We produce medium- and low-voltage switchgear, false floor systems, and mechanical components tailored to customer needs. Together with our affiliated company COMEXIO, we provide solutions for building automation, energy management, and storage. Continuous development ensures we meet and anticipate customer requirements, with a strong focus on quality and service.
Greiner Transformer Skid (GTS)
The GTS is a cost-efficient, ready-to-use solution for grid connection of ground-mounted PV plants. It connects up to 22 inverters, reducing costs, space, and complexity.
Equipped with 24 kV medium voltage switchgear, a 5,000 kVA transformer, and 800 V / 4,000 on low-voltage side, it is optimized for modern high-performance systems. Manufactured in Germany and delivered ready for connection, it minimizes installation time and speeds up commissioning.
The concrete-free skid design lowers CO₂ emissions, improves natural cooling, and increases system lifespan—without active cooling. Result: lower CAPEX and OPEX with high reliability.
Key benefits:
• Up to 22 inverters per station
• Reduced system and installation costs
• 5,000 kVA at 24 kV
• 800 V / 4,000 A
• Made in Germany
• Ready-to-connect delivery
• Sustainable, concrete-free design
• No active cooling required
A reliable, future-proof solution for efficient PV projects.
