How to choose the right power

Sizing starts with the loads the generator must support: lifts, ventilation, pumps, medical equipment and process lines. Add their power requirements, then include a reserve for motor starting, which briefly demands several times the nominal current.

Do not oversize excessively: a generator operated for long periods at too little load does not work at its optimum point. Send us your load list and we will size the correct rating from the 65-330 kVA range and tell you whether a 250 kVA generator covers the requirement or whether the adjacent rating is more suitable.

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 line is rated for both, so it can operate either as the main source or as backup.

Autonomy depends on tank capacity and load. The integrated tank covers a typical standby duty, while extended operation can use a larger tank or external fuel supply. Diesel consumption at 75% and 100% load is stated in the datasheet for each rating.

Why diesel

For industrial power levels, the diesel engine remains the solution with the best balance of cost, autonomy and reliability. It offers high energy density, controlled fuel consumption under load and durability in intensive operation, unlike petrol generators, which are limited to lower power levels.

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 is the standard backup choice for buildings, industry and critical infrastructure.

Components and construction

The technical platform is common across the entire line: liquid-cooled diesel engine, brushless alternator with 100% copper windings and automatic voltage regulator, digital controller with protections, and a frame with anti-vibration mounts for stable installation.

Components are selected for continuous operation and easy spare-parts support. A generator built on a unified platform is easier to maintain and troubleshoot, regardless of the selected power rating.

Configurations and options

Each 250 kVA generator is supplied in the configuration suited to its installation site: open for a technical room or hall, soundproof enclosed for low-noise outdoor installation, or containerized and ready to position, with external access to the control panel.

Options include an ATS automation panel for automatic mains-generator transfer, an extended fuel tank for greater autonomy, industrial sockets and a remote monitoring system. The three-phase output connects directly to the installation's main distribution board.

Applications and industries for the 250 kVA generator

A 250 kVA generator is used in hospitals, hotels, shopping centres and medium-sized factories as a backup source for the entire building. When the grid fails, it automatically takes over critical loads, from lifts and ventilation to medical equipment and safety systems.

In industry and large livestock farms, an industrial diesel generator supports continuous processes: production lines, refrigeration systems, ventilation and pumping. Three-phase power handles heavy motor starting, while the soundproof enclosure reduces noise in staffed areas.

For medium-sized data centres and non-stop facilities, a 250 kVA generator forms part of the continuity plan. See the full GENKRAFT diesel generator range for lower or higher power ratings, or request sizing from the GENKRAFT technical team. The equipment carries CE marking in accordance with the applicable requirements of the Machinery Directive 2006/42/EC.

Whatever the application, a 250 kVA generator delivers the same stable three-phase power, with optional automatic starting and a configuration selected for the installation site. A common technical platform across the 65-330 kVA range means shared parts and predictable service.

How it works

A 250 kVA generator follows a simple sequence from mains 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. Within a few seconds of the outage, the ATS transfers the load to the generator without human intervention.
5. When mains power returns, the system transfers the loads back and stops the engine after the cool-down period.
6. The digital controller monitors operating parameters and shuts the set down on protection events, with an alarm log.

Frequently asked questions

What do prime and standby power mean for a 250 kVA generator?

Prime is the continuous power rating for unlimited hours per year; standby is the emergency rating for limited hours without overload. Both are stated according to ISO 8528 in each rating's datasheet.

What power range does the line cover?

From 65 to 330 kVA. The 250 kVA generator is a mid-range configuration; choose the rating that fits your building or production facility.

Does it automatically take over the building during a power outage?

Yes. With an ATS panel, an industrial diesel generator starts and transfers the load within seconds, then automatically returns to mains power. For critical buildings, we recommend an ATS as standard.

Can it be installed outdoors?

Yes, in a soundproof enclosed or containerized version. A 250 kVA generator is weather-resistant and reduces noise, so it can be installed in the facility yard.

What maintenance does it require?

Basic maintenance means checking the oil, filters, coolant and battery at the intervals specified in the manual. The digital controller provides early alarm indications, and regular maintenance ensures a long service life.

Can it be monitored remotely?

Yes, optionally. With the monitoring module, generator status, fuel level and alarms can be viewed remotely over the network, which is useful for unattended sites.

How do I order and receive a quote?

Choose the power rating and configuration, then request a quote. We confirm the configuration, price and delivery time. Because each unit is prepared to order, you receive exactly the version suited to your project.

What is the noise level in the enclosed version?

The soundproof enclosure significantly reduces noise compared with the open version, allowing the generator to operate near the building. The exact dB(A) level at 7 metres is stated in the technical datasheet for each power rating.

Do you deliver nationwide?

Yes, we deliver throughout Romania. Electrical connection and commissioning are performed by an authorised electrician in accordance with the site's electrical design, and we provide the required technical documentation.

Is it eligible for projects funded by European funds?

Yes. The equipment comes with CE marking and conformity documentation, so it can be included in co-financed investment projects. On request, we provide the technical datasheet and certifications for the financing file.
