Industrial standby source
300 kVA diesel generator
Rated output: 300 kVA · Approx. 240 kW at PF 0.8 · Voltage: 400 V / 50 Hz
300 kVA generators are the standard solution for large industrial operations, hotels, hospitals and smaller data rooms. The 240 kW output (at PF 0.8) can support selected facility loads — process equipment, air-conditioning and safety systems — with the final coverage verified from the load profile.
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 300 kVA project is confirmed during sizing, never assumed.
Typical use
Typical applications for a 300 kVA generator
Large industrial plants
Backup for industrial halls with machinery, compressors and energy-intensive processes.
Hospitals
Backup for a whole hospital or clinic — operating theatres, ICU, ventilation and diagnostic equipment.
Hotels and resorts
Uninterrupted operation of lifts, air-conditioning, kitchens and safety systems.
Data rooms (Tier II)
Backup for mid-size data rooms, operated in combination with a UPS system.
Shopping centres
Backup for the whole centre — food refrigeration, lighting, escalators and lifts.
Water treatment plants
Backup for pumping stations and treatment technology with a critical availability requirement.

Typical configuration of a 300 kVA generator
Automatic transfer switch (ATS)
Changeover to backup power in about 10 seconds with automatic shutdown after grid recovery on suitable models.
Remote monitoring options
GSM alarm notifications and remote diagnostics of output, temperatures, fuel consumption and alarm states where supported by the control unit.
Redundant backup (N+1)
For critical operations, two generators in an N+1 configuration can be engineered as a project redundancy design — sized individually per project; loads that must ride through the changeover typically require UPS support.
Fuel tank options
Tanks for around 24–48 hours at full output, connectable to external storage tanks 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
300 kVA — common questions
Is a 300 kVA generator the right size for my project?
A 300 kVA rating corresponds to roughly 240 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 300 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.
How is a 300 kVA generator delivered abroad?
International supply is a direct generator sale, preferably EXW CZ/NL, with transport arranged individually. Installation and service abroad are not globally promised — they are assessed and confirmed per destination and model, through our team or a local partner.
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.
