For data centres, heavy industry and critical infrastructure, a 900 kVA generator provides large-scale backup power where an outage is extremely costly. GENKRAFT covers the top end of the range, from 780 to 900 kVA, with stable three-phase power at the highest power level.
It is one configurable product: choose the power, configuration and options. A 900 kVA generator delivers stable three-phase power at 400 V and 50 Hz, with prime and standby ratings, and automatically takes over very large loads within seconds of a grid failure.
• Configurable 780-900 kVA range: choose the right power level, from the smallest to the largest rating in the line, without paying for unused capacity.
• Prime and standby ratings are stated in accordance with ISO 8528, so you know exactly what a 900 kVA generator delivers in each operating mode.
• Stable three-phase supply at 230/400 V and 50 Hz, matching the Romanian grid standard and suitable for motors and sensitive equipment.
• Automatic start on mains failure with an optional ATS panel, so a 900 kVA generator takes over the loads without human intervention.
• Three configurations: open for a technical room, soundproof enclosed for outdoor installation, and containerized for a fully independent installation.
• Liquid-cooled diesel engine and brushless alternator with 100% copper windings, components selected for reliable operation and dependable starting.
• CE marking and conformity documentation, making the 900 kVA generator eligible for projects financed with European funds.
• Direct-supplier pricing without the markup of an expensive brand: you pay for the technology and components, not the name on the enclosure.
A 900 kVA generator is part of a unified product line: the power rating changes while the platform remains the same. The values below are actual prime and standby ratings. Exact dimensions and weight are confirmed in the technical datasheet for each power step.

Sizing starts with the loads the generator must support: data centres, pumping stations, industrial refrigeration systems and continuous processes. 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 780-900 kVA range and tell you whether a 900 kVA generator covers the requirement or whether the adjacent rating is more suitable.
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.
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.
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.
Each 900 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.
A 900 kVA generator supplies data centres, large industrial sites, utilities and critical infrastructure. As a backup source it automatically takes over the entire site during an outage; as a main source it supports loads beyond the capacity of a conventional grid connection.
In heavy industry and utilities, a high-power diesel generator supports very large equipment, pumping stations, industrial refrigeration systems and continuous processes. Soundproof enclosed or containerized construction allows rapid installation with external access to the control panel.
For large-scale redundancy, multiple units can be paralleled into a standby power plant. See the full GENKRAFT diesel generator range and the intermediate 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 900 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 780-900 kVA range means shared parts and predictable service.
As a reseller, we prepare every order to the selected configuration: power, enclosure, voltage and options. Delivery time therefore depends on the configuration and is confirmed in the quotation together with the final price.
At delivery, the equipment comes with CE marking and conformity documentation. On request, we provide the technical datasheet and certifications required for a financing file. Electrical connection and commissioning are performed by an authorised electrician in accordance with the site's electrical design.
A 900 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.
What do prime and standby power mean for a 900 kVA generator?
Prime is the continuous power rating for unlimited hours per year; standby is the emergency rating for limited hours without overload. The 900 kVA generator line is rated for both according to ISO 8528, as shown in each rating's datasheet.
Is it supplied in a containerized version?
Yes. At this power level, a large diesel generator is frequently supplied in a soundproof container, ready to position, with external access to the control panel and an integrated exhaust silencer.
Can multiple units be connected in parallel?
Yes. For additional power or N+1 redundancy, a 900 kVA generator can be paralleled with other units through a synchronization panel, forming an automatically managed standby power plant.
Does it automatically take over the load during a power outage?
Yes. With an ATS panel, a 900 kVA generator starts and takes over the load within seconds, then automatically switches back to the grid. For critical facilities, automation is part of the standard configuration.
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.
