Industrial and data-centre generator
500 kVA diesel generator
Rated output: 500 kVA · Approx. 400 kW at PF 0.8 · Voltage: 400 V / 50 Hz
500 kVA generators are among the most-used outputs for backing up industrial plants, data rooms and energy projects. The 400 kW output (at PF 0.8) backs up a large production hall or an entire mid-size industrial site. Available from AKSA, Himoinsa, Energy Gruppi and Inmesol.
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 500 kVA project is confirmed during sizing, never assumed.
Typical use
Typical applications for a 500 kVA generator
Large production plants

Backup for mid-size data rooms with redundant configuration and changeover in about 10 seconds.
Energy projects
Primary or backup power for off-grid industrial sites and energy infrastructure.
Rental companies
A powerful unit for short-term hire on large construction and industrial projects.
Industrial parks and campuses
Backup for industrial parks, technology campuses and multi-building sites.
Water infrastructure
Backup for waterworks, pumping stations and treatment plants with a 24/7 availability requirement.

Typical configuration of a 500 kVA generator
Automatic transfer switch (ATS)
Automatic changeover to backup power in about 10 seconds on suitable models, with smooth return and shutdown after grid recovery.
Parallel synchronisation
Multiple 500 kVA units in parallel for scalable output and N+1 configurations — designed and confirmed as part of the project.
Remote monitoring options
GSM alarm notifications and real-time remote diagnostics of output, fuel, temperatures and unit status where supported by the control unit; SCADA/DCIM integration as an individual project solution.
Fuel tank options
Tanks for around 48–72 hours of continuous operation, 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
500 kVA — common questions
Is a 500 kVA generator the right size for my project?
A 500 kVA rating corresponds to roughly 400 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 500 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.
Which manufacturers are available at 500 kVA?
We supply this output from AKSA, Himoinsa, Energy Gruppi and Inmesol. ESKO Generator is an authorised AKSA dealer for the Czech Republic and Slovakia; all units come with the manufacturer's warranty, and the recommended brand depends on your configuration, duty and delivery requirements.
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.
