Industrial standby source
250 kVA diesel generator
Rated output: 250 kVA · Approx. 200 kW at PF 0.8 · Voltage: 400 V / 50 Hz
250 kVA generators are a capable standby source for industrial operations, logistics centres and smaller data rooms. The 200 kW output (at PF 0.8) covers the critical systems of a mid-size plant, an entire administrative centre or an automated industrial warehouse.
Duty types
PRP and ESP are not interchangeable
ESP — standby power
Emergency operation during grid outages at variable load. The rating applies to limited-hour standby duty, not continuous running.
PRP — prime power
Variable continuous operation as the main power source. A prime rating is lower than the standby rating of the same unit and is confirmed per engine and application.
Tell us the intended duty when you inquire — the required rating (PRP or ESP) for your 250 kVA project is confirmed during sizing, never assumed.
Typical use
Typical applications for a 250 kVA generator
Industrial production plants
Backup for a mid-size production hall — lines, machines, lighting, air-conditioning and safety systems.
Logistics and distribution centres
Uninterrupted operation of automated warehouses, cold stores and sorting centres.
Small data rooms (Tier II)
Backup for server rooms and colocation sites, operated in combination with a UPS system.
Retail parks
Backup for an entire retail park — lighting, refrigeration, checkouts and security systems.
Hospital pavilions
Backup for a hospital department or outpatient clinic — continuous operation even during longer outages.
Infrastructure projects
Primary power for large construction projects — motorways, tunnels, bridges and industrial buildings.

Typical configuration of a 250 kVA generator
Automatic transfer switch (ATS)
Unattended changeover to backup power in about 10 seconds on suitable models — configuration agreed per project.
Remote monitoring options
GSM alarm notifications and remote diagnostics of output, fuel level, running hours and alarms where supported by the control unit.
Load management
Staged load reconnection after start to protect sensitive equipment — depends on the selected control configuration.
Fuel tank options
Optional extended or external fuel tanks sized for the required runtime and load, depending on the model.
All options above are project variants depending on the selected model and agreed scope — they are not universal features of every unit. Tank autonomy, sound levels, monitoring interfaces, HVO compatibility and paralleling are confirmed for the specific configuration in your quotation. All units come with the manufacturer's warranty.

Frequently asked questions
250 kVA — common questions
Is a 250 kVA generator the right size for my project?
A 250 kVA rating corresponds to roughly 200 kW of usable output at a power factor of 0.8. Compare the total connected load of your facility, including starting currents of the largest motors, with the continuous load you need to sustain. Our engineers verify the final sizing from your actual load profile before a quotation.
Is 250 kVA a standby (ESP) or prime (PRP) rating?
Both duty types exist in this power class, and the numbers are not interchangeable: an ESP (standby) rating applies to emergency operation during grid outages, while PRP (prime) applies to variable continuous operation. Always tell us the intended duty — the required rating (PRP or ESP) is confirmed during project sizing, never assumed.
Can 250 kVA units be configured for N+1 redundancy?
Yes. For critical operations, two or more units can be operated in parallel with a designed reserve. Paralleling depends on the selected models and control equipment and is always engineered and confirmed as part of the project — loads that must ride through the changeover typically require UPS support.
Czech projects
Supply, design, commissioning or turnkey
For Czech customers we can deliver the generator alone, design the installation, commission it on a prepared site, or realize the project turnkey — with contracted service according to the agreed scope. The scope is clarified during consultation.
International
Direct sale, preferably EXW CZ/NL
International customers receive a direct generator sale, preferably EXW CZ/NL, with transport arranged individually. Installation and service abroad are confirmed individually per destination and model.
Availability and dispatch
Availability depends on the rating — the current stock list starts at 25 kVA ESP, and availability of the requested rating is confirmed in your quotation. Confirmed warehouse units can be dispatched within 48 hours after the order, conditions and payment are closed — a dispatch time, not a delivery-time promise. The current stock list covers models that are in stock or in transit.
