Energy systems & renewable energies

Your partner around the energy systems

Our experts support you at every stage, from the idea to the first drafts to the finished product. Your goal is a safe and smooth market approval? We offer you a complete service program for this purpose: Technical development assistance, training, product testing, approvals, inspections, audits, conformity assessments, certifications, approvals in international markets, and listings in online databases for worldwide market access.

We are happy to support you for the following and similar product categories:

  • Converters / Inverters for photovoltaic / wind / hydro or fuel cell applications etc.
  • Energy storage, battery storage systems and charging stations
  • Combined heat and power plants (CHP) and combined heat and power plants (CHP)
  • Organic Rankine Cycle (ORC) plants
  • Electric generators with various drives
  • Uninterruptible power supply (UPS) and emergency power systems
  • Mains and system protection devices (NA protection), measuring relays and protection devices
  • Park controllers, control and communication devices
  • Connection, distribution and monitoring boxes
  • Low-voltage switchgear and combinations

The main subject areas here are ensuring electrical safety and obtaining a grid connection or a grid conformity declaration for the grid operators. For further questions in this complex of topics (different worldwide requirements, environmental simulation, IP “Ingress Protection”, EMC or CE declarations) you can also rely on our experience.
