500kva generator hire
A 500 kVA diesel generator delivers 400 kW of usable power — enough to run a large construction site, an industrial facility, a data centre on backup, or a major event. Rental Power supplies serviced, load-tested 500 kVA units from Cummins and Perkins across Dubai, Abu Dhabi and Sharjah, delivered and connected on-site. The exact specs are below — fuel consumption, output, footprint — so you can confirm this is the right size before you book.

What a 500 kVA Generator Powers
A 500 kVA set gives you around 400 kW of continuous usable load. Realistic uses:
- Large construction site — multiple tower cranes, concrete plant, welding, site-wide lighting and offices on one supply
- Industrial facility / factory — process machinery, compressors and production lines
- Data centre or hospital backup — critical load with the headroom to carry HVAC and IT together
- Major event or concert — full staging, lighting rig, sound, catering and cooling
- Prime power on an isolated site — oilfield, remote camp or a location with no reliable grid
If your total load is above roughly 350 kW, step up to a 1000 kVA generator or run multiple units in synchronisation. If you’re well under 300 kW, a 100 kVA generator or mid-size set will cut your fuel and generator rental cost — our team will size it for you.
500 kVA Generator Specifications
| Specification | Value |
|---|---|
| Prime output | 500 kVA / 400 kW |
| Standby output | 550 kVA / 440 kW |
| Voltage | 400V 3-phase / 230V single-phase |
| Full-load current | 722 amps at 400V, 3-phase |
| Frequency | 50 Hz |
| Speed | 1500 rpm |
| Power factor | 0.8 |
| Engine options | Cummins, Perkins |
| Enclosure | Silent canopy or open-frame |
| Base fuel tank | ~850–900 litres (approx. 8 hrs at full load) |
500 kVA Generator Fuel Consumption
Fuel is the biggest cost on a set this size, so plan around it. Approximate diesel use for a 500 kVA generator by load:
| Load | Power drawn | Fuel use |
|---|---|---|
| 25% | 100 kW | ~30 litres/hour |
| 50% | 200 kW | ~52 litres/hour |
| 75% | 300 kW | ~76 litres/hour |
| 100% | 400 kW | ~100 litres/hour |
Most sites run near 50% load, so expect roughly 52 litres/hour — around 1,250 litres on a 24-hour day. The standard base tank holds ~850–900 litres for about 8 hours at full load; larger external bulk tanks are available for extended runtime. We quote fuel as a separate line item, so there are no billing surprises.
Dimensions, Weight & Site Placement
A 500 kVA set is heavy plant — plan access and ground before delivery day:
| Specification | Silent (canopied) | Open-frame |
|---|---|---|
| Length | ~5.5 m | ~3.4 m |
| Width | ~1.2 m | ~1.5 m |
| Height | ~2.5 m | ~2.2 m |
| Weight | ~4,900 kg | ~3,900 kg |
Placement requirements:
- Firm, compacted ground or hardstanding able to take ~5 tonnes
- Delivered by crane/hiab or low-loader — needs clear, wide access for offloading
- Room around the unit for airflow, exhaust dispersal and refuelling access
- Silent canopy for noise-sensitive sites like events, hospitals and occupied buildings
What’s Included With Every 500 kVA Rental
Every unit arrives ready to run:
- Base fuel tank
- Distribution board
- Manual or automatic changeover switch
- Synchronisation panel (for multi-unit setups)
- Cables and cable ramps
- Delivery, installation and on-site load testing
- 24/7 support for the rental period
Cable and breaker sizing is handled by our technicians on-site — a 500 kVA set draws 722 A, so it pairs with an 800A main breaker and appropriately rated cabling, sized to your load and run.

Silent vs. Open-Frame 500 kVA
- Silent / acoustic — our fully enclosed silent generator is built for noise-sensitive sites like events, hospitals, hotels and occupied buildings
- Open-frame — lower cost, faster to deploy, best for open industrial sites, oilfields and yards
Both available for immediate hire across the UAE. For continuous high-load industrial duty, see our heavy duty generator range.
FAQs
How many amps is a 500 kVA generator?
722 amps at 400V, 3-phase, 50 Hz. Tell us your connection and we’ll confirm for your setup.
How much fuel does a 500 kVA generator use per hour?
Around 52 litres/hour at 50% load and up to ~100 litres/hour at full load, depending on your load profile.
What can a 500 kVA generator run?
About 400 kW of load — a large construction site, an industrial facility, a data centre or hospital on backup, or a major event. Above ~350 kW, step up to 1000 kVA or synchronise multiple units.
How big is a 500 kVA generator?
A silent 500 kVA unit is roughly 5.5 m long, 1.2 m wide and 2.5 m high, weighing about 4,900 kg. It needs compacted ground and crane or low-loader access for placement.
Can I run two 500 kVA generators together?
Yes — units can be synchronised to share load or provide N+1 redundancy for critical sites. We supply the sync panels and set it up on-site.
What’s the minimum rental period for a 500 kVA generator?
We offer short-term and long-term rentals — get in touch with your project dates and we’ll confirm terms.
