A 30 kVA generator gives you 24 kW of power. That is enough to run a villa with the AC on, a small restaurant, a site office, or a shop during a power cut. It is the smallest set we rent, and the one people ask for most when they need backup power without paying for a machine that is too big for the job. We deliver anywhere in Dubai, usually within a few hours. Our team connects it, tests it under load, and shows you how to run it before we leave.

Breakdown Support On Every Rental
Two or three split AC units, lights, fridge, TV, water pump and general sockets. A 30 kVA set covers a typical 3 to 4 bedroom villa during a DEWA outage or planned maintenance.
Kitchen equipment, chillers, lights and POS systems. Big commercial ovens and walk in freezers may need more, so send us your equipment list and we will check.
Portacabins, AC units, lights and small tools. Common on construction sites before the permanent supply is connected.
Lighting, AC and everyday equipment. Keeps you trading through an outage instead of closing.
Lighting, sound, catering equipment and a few AC units for a marquee. For anything bigger, look at 50 kVA or 100 kVA.
Welding sets, concrete mixers, small hoists and site lighting.
A tower crane, a batching plant, a chiller plant, or a full commercial kitchen with walk in cold rooms. Those need 100 kVA and up. If you are not sure, just ask. Sizing it right is free and it takes us five minutes.
Tell us what you’re running and where you are in Dubai. You’ll have a quote back within a few minutes, and a set on site the same day where we have availability.
Total Power, diesel generator rental Dubai contractors depend on, from 30 kVA to 1200 kVA.
From construction and events to factories and facilities, our diesel generator rental covers supply, delivery, setup, maintenance and support across Dubai and the UAE.
It’s a simple formula. You can convert between kVA and kW in just a few seconds.
The actual value can vary depending on the generator model and your equipment
Quick reference for popular generator sizes and their usable power.
We run a mixed fleet so we can match the engine to the job — Japanese ultra-silent sets for urban and event work, heavy European and American industrial engines for continuous site load
Electric, with optional auto start
Water cooled
Fuel is usually the biggest running cost, so here are honest numbers.
| Load | Fuel Use | What That Looks Like |
|---|---|---|
| 25% (Light) | About 2 litres per hour | Lights and a few sockets |
| 50% (Half) | About 3.5 litres per hour | Villa with one or two ACs running |
| 75% (Typical) | About 5.3 litres per hour | Busy shop or small site |
| 100% (Full) | About 7 litres per hour | Everything on at once |
Most jobs run at 50 to 75%, so budget around 4 to 5.5 litres an hour.
On a 170 litre tank at typical load, that is roughly 30 hours before refuelling. A full day and night with room to spare.
One tip that saves money: do not run a generator below about 30% of its capacity for long periods. It burns more fuel per unit of power and it is not good for the engine. If your load is genuinely small, a 30 kVA set is already the right size. Going bigger “just in case” costs you more, not less.
Use it for temporary power during electrical maintenance or upgrade work.
Is the power your equipment uses while it is on. Add it up in kilowatts.
Is the extra power motors pull for a second or two when they switch on. An AC compressor can draw three to five times its running load at startup. This is what catches people out. The generator handles the running load fine, then trips the moment the AC kicks in.
We work both out for you. Send a list of what you are powering on WhatsApp and you will get an answer the same day. There is no charge and no obligation
30 kVA is generally suitable
Consider a 40 or 50 KVA generator
Consider 80 KVA or 100 kVA
Which to pick: if your load sits close to 20 kW, go up to 40 kVA. Running a generator near its ceiling all day wears it harder and gives you no headroom when something extra switches on.
Undersizing means tripping and downtime. Oversizing means paying for capacity you never use, plus worse fuel economy. Getting it right the first time is cheaper than either.
| Specification | 30 kVA | 40 kVA | 50 kVA |
|---|---|---|---|
| ϟ Usable power | 24 kW | 32 kW | 40 kW |
| ♧ Rated current | 43 A | 58 A | 72 A |
| ⛽ Fuel at 75% load | 5.3 L/hr | 7.8 L/hr | 9 L/hr |

Our 30 kVA sets come in a sound attenuating canopy, which cuts noise considerably compared with an open frame machine. Measured levels run from 75 dB(A) at 7 metres on our quieter units.
The canopy is weatherproof and lockable, so it handles Dubai summers and sits outside safely overnight.
If you are powering an event or a villa in a residential area, tell us when you book. Noise matters in those settings, and we will make sure you get one of the quieter units in the fleet and advise on where to position it.
Delivery, lifting, cable termination, earthing and load testing are shown as separate line items, priced clearly.
Distribution boards, extra cabling, transfer switches, and fuel supply for event hires.
See what your site needs ready. Access width, level ground and an earthing point. Two minutes of checking prevents a failed delivery.
Minimum period, deposit and off hire notice are all on our rental terms page.
The rate depends on how long you need it, whether you want fuel supplied, and how easy your site is to reach. Weekly and monthly rates are available, and longer hires cost significantly less per week.
Send us your dates and location and you will get a written quote covering rental, delivery, collection, everything in one number.

Answers to the questions contractors and event teams ask most about diesel generator rental in Dubai, sizing, delivery, fuel, silent sets and breakdown cover.
24 kW. Generators are rated in kVA, but your equipment is rated in kW, and the conversion is kVA x 0.8. So a 30 kVA set gives you 24 kW of usable power.
No, and this catches people out. A 30 kVA generator produces 24 kW. If you need a full 30 kW, you need a 40 kVA set. Going the other way, a "30 kW generator" is actually a 37.5 kVA machine.
Add up your equipment in kW, then divide by 0.8 to get the generator size in kVA. Or send us the list and we will work it out. It takes us a few minutes and it is free.
43 amps at 400V three phase. If you are working in single phase, the figure is different, so send us your setup and we will confirm.
About 5.3 litres an hour at 75% load, which is where most jobs sit. At full load it is around 7 litres an hour, and at half load about 3.5.
Yes. A 30 kVA set comfortably runs a typical 3 to 4 bedroom villa including two or three AC units, lights, fridge and water pump. Larger villas with more ACs may need 50 kVA.
Usually two to four split units, depending on their size and what else is running. AC compressors draw a big spike at startup, so we always check the full load before confirming.
Ours are 400V three phase, which suits most commercial and site equipment. If you specifically need single phase, tell us when you enquire.
Around 30 hours at typical load on a 170 litre tank. Smaller tanks give roughly 18 to 20 hours.
