18 kVA GENKRAFT Stage V diesel generator, EU-compliant emissions

Need a generator that meets Europe’s strictest emissions requirements? A GENKRAFT Stage V diesel generator is exactly that: an 18 kVA three-phase generator compliant with the EU Stage V emissions standard, designed for locations where emissions matter, from urban construction sites to rental fleets.

A Stage V diesel generator delivers stable three-phase power at 400 V and 50 Hz, with 14.5 kW prime power and 16 kW standby power. The engine complies with Stage V emissions limits, so the generator can be used legally where older engines are not permitted to operate.

Advantages of a GENKRAFT Stage V generator

• Compliant with the EU Stage V emissions standard, Europe’s strictest standard for engines, so a Stage V diesel generator is accepted even where older engines are prohibited.
• Reduced particulate and nitrogen oxide emissions, a real advantage in cities, ventilated enclosed spaces and protected areas.
• Stable three-phase power at 400 V and 50 Hz, with 230 V per phase for single-phase loads connected to the system.
• Automatic start on grid failure with an optional ATS panel, allowing the Stage V diesel generator to take over the loads without human intervention.
• Two versions: open for a technical room and soundproof enclosed for outdoor installation with reduced noise.
• CE marking and conformity documentation, so the equipment is eligible for projects financed with European funds.
• Direct-supplier pricing without the markup of an expensive brand: you pay for the technology and compliance, not the name on the enclosure.

What EU Stage V means and why it matters

Stage V is the latest stage of European emissions standards for non-road mobile machinery engines, established by Regulation (EU) 2016/1628. It imposes strict limits on particulates and nitrogen oxides, more stringent than previous stages, and applies to engines used in machinery and mobile equipment.

In practice, more and more European markets and authorities require Stage V compliance for mobile equipment, especially on urban construction sites and in environmentally restricted areas. A Stage V diesel generator gives you access to these projects, where a non-certified generator may simply not be permitted.

What you gain from lower emissions

A Stage V-compliant generator is not only about meeting regulations. Lower particulate and nitrogen oxide emissions mean cleaner air around the equipment, a real advantage when working near people, in ventilated semi-enclosed spaces or residential areas.

In addition, equipment that is compliant today remains usable tomorrow: as emissions restrictions expand across Europe, a Stage V model is less likely to be excluded from important markets. It is an investment that retains its value over time.

Applications for a Stage V diesel generator

A Stage V diesel generator is an ideal solution for equipment-rental companies, where machines move frequently and must be accepted on any jobsite, including cities with emissions rules. Stage V compliance can become the argument that wins the contract.

On urban construction sites, infrastructure works and in residential areas, a Stage V generator powers tools, pumps and site facilities while meeting local emissions limits. The soundproof enclosed version also reduces noise, which is essential near homes.

For events, filming and trailer-mounted mobile applications, a Stage V diesel generator provides clean and quiet power. See the full GENKRAFT diesel generator range for higher power ratings or standard versions, or request details from the GENKRAFT technical team.

Operating mode and autonomy

ISO 8528 defines prime power (PRP), available for an unlimited number of hours per year, and emergency standby power (ESP), available for a limited number of hours without overload. This model is rated for both, so it can operate as either a prime or standby source.

Runtime depends on tank capacity and load. The integrated tank covers typical operation, while an extended tank can be added for longer runtime. Diesel consumption at 75 and 100 percent load is specified in the technical datasheet.

Why diesel

For loads that operate frequently or at high power, diesel outperforms petrol: lower fuel consumption at the same output, longer runtime, better torque and longer service life. Stage V technology adds significantly reduced emissions to these advantages.

Unlike a UPS, which covers only a few minutes, a diesel generator can support the load for hours or days as long as fuel is available. That is why it remains a practical choice for mobile and standby power.

Components and construction

The technical platform consists of a Stage V-compliant liquid-cooled diesel engine, a 100% copper brushless alternator with automatic voltage regulation, a controller with protections and a frame with anti-vibration mounts for stable installation.

Components are selected for reliable starting and readily available spare parts. The exhaust after-treatment system required for Stage V is integrated into the generator design.

Configurations and options

A Stage V diesel generator is supplied either open for a technical room or in a soundproof enclosure for low-noise outdoor installation. The enclosure protects the equipment from weather and makes it suitable for construction sites or placement next to a building.

Options include an ATS panel for automatic grid-generator transfer, an extended fuel tank for longer runtime, industrial sockets and a monitoring system. The configuration is selected according to your application.

Installation, delivery and documentation

As a reseller, we prepare each order to the selected configuration: enclosure type and options. Delivery time depends on the configuration and is confirmed in the quotation together with the final price.

On delivery, the equipment includes CE marking, conformity documentation and Stage V emissions documents. Electrical connection and commissioning must be carried out by an authorised electrician in accordance with the site electrical design.

How it works

A Stage V diesel generator follows a simple sequence from grid failure to restoration:

1. The mains sensor detects loss of supply or a voltage deviation in the public grid.
2. The ATS automation panel commands the diesel engine to start and disconnects the mains.
3. The generator reaches rated speed and the alternator delivers stable three-phase voltage.
4. The Stage V system treats the exhaust gases, keeping emissions within the required limits.
5. When mains power returns, the system transfers the loads back and stops the engine after the cool-down period.
6. The controller monitors operating parameters and shuts the set down on protection events, signalling alarms.

Frequently asked questions

What does Stage V diesel generator mean?

It means the engine complies with the European Stage V emissions standard, the strictest stage for non-road mobile machinery engines. It emits far fewer particulates and nitrogen oxides than a non-certified engine.

Where is a Stage V generator required?

Increasingly on urban construction sites, in environmentally restricted areas and in mobile rental applications across the European Union. Check the local requirements for your project; we provide the compliance documentation.

What power does this model provide?

The Stage V diesel generator provides 14.5 kW / 18 kVA prime power and 16 kW / 20 kVA standby power at 400 V three-phase. It is a single model, not a range.

Is it single-phase or three-phase?

It is three-phase at 400 V and supplies 230 V per phase for single-phase loads connected to the system, subject to phase balancing.

Can it start automatically when the mains power fails?

Yes. With an ATS panel, a Stage V generator starts automatically when the grid fails and stops when the grid returns. The ATS is optional and is included in the quotation when requested.

What emissions documents do I receive?

You receive documentation confirming the engine’s Stage V compliance together with CE marking and the technical datasheet. These documents are useful both for authorities and for funding applications.

Is it eligible for projects funded by European funds?

Yes. A Stage V diesel generator comes with CE marking and conformity documentation, and Stage V compliance is an additional environmental advantage. We provide the certificates required for the funding file.

How is it different from a conventional diesel generator?

The difference lies in the engine and exhaust after-treatment: a Stage V model emits far fewer particulates and nitrogen oxides. Power, voltage and enclosure options work in the same way as on a standard diesel generator.

Can it be moved easily between construction sites?

Yes. On request, it can be supplied on a frame with lifting points or trailer-mounted, suitable for rental companies and frequent moves between locations.
