Stage V emissions directive and legal requirements

Stage V describes the European emissions standard for combustion engines in mobile machinery and equipment. This emissions class is crucial for many new mobile generators and power units, especially on construction sites, in rental fleets, for public tenders, and in applications with environmental requirements.

Public tenders: Stage V or comparable standards may be explicitly required.
Inner-city deployments: Low-emission engines are often an important factor in decision-making in sensitive areas.
ESG and sustainability: Companies can incorporate Stage V technology into their requirements for lower-emission construction sites and projects.

Stage V is based on the European regulation for engines in non-road mobile machinery. For stationary installations or larger, continuous-running machines, additional national regulations or requirements for medium-sized combustion plants may also apply. Therefore, the specific classification should always be assessed based on the type of use, location, mobility, and operating hours.

Important for project planning and tendering

For mobile construction site, rental and infrastructure projects, emission requirements should be clarified early on so that performance, engine technology and documentation are suitable for the application.

Clarify requirements

Power ranges from 5 to 500 kVA and typical applications

Stage V generators can cover very different power classes depending on the project. Crucial factors include not only the rated power, but also starting currents, load profile, operating mode, reserve power, and potential expansion options.

5 to 40 kVA

Compact generators for mobile construction sites, trades, smaller industrial applications, offices, IT or temporary power supply.
