Wedding and Tent Generator Rental in Sharjah and Dubai: How Many KVA Do You Need?
Most weddings and tents need roughly 30 to 125 KVA, and air conditioning is the deciding factor. This guide gives a sizing table by guest count and AC tonnage, a quick calculation method, and a pre-booking checklist.
Short answer: a tent wedding for 200 guests with roughly 10 tons of air conditioning usually needs a 60–80 KVA generator. A small tent or majlis for up to 100 guests runs on about 30 KVA, while a large wedding of 500+ guests typically starts at 125 KVA and goes up. Air conditioning alone eats 60–70% of the load, so calculate it first, then add lighting, sound and catering, and put a 25% safety margin on top.

Where does the load come from? AC first
The most common wedding mistake we see: people count lights and speakers and forget that air conditioning is the real load.
- Air conditioning: one ton of cooling draws roughly 1.5–2 kW of electricity while running, and the compressor pulls a higher starting current at switch-on. A 10-ton tent setup means a load of about 15–20 kW on its own.
- Lighting: modern LED lighting is relatively light; older floodlights, display lighting and decorations are far heavier than you would expect.
- Sound and band: a mid-size sound system needs roughly 3–8 KVA, more with screens and stage lighting.
- Catering: kettles, warmers, coffee machines and buffet equipment — silent loads that add up fast.
- UAE heat: a generator loses part of its real output as temperatures pass 40°C, which is one more reason the safety margin is a necessity, not a luxury.
Approximate sizing table for weddings and tents
| Event type | Guests | Approx. AC | Suggested size |
|---|---|---|---|
| Small tent / majlis / farm | Up to 100 | 5 tons | About 30 KVA |
| Medium tent wedding | 150–250 | 10 tons | 60–80 KVA |
| Large wedding | 300–500 | 15–20 tons | 100–125 KVA |
| Very large wedding or event | 500+ | 25+ tons | 200 KVA+, or two units |
These are guide figures; the exact calculation comes from your contractors' actual AC and sound equipment lists.
How to calculate it yourself in two steps
- Add up your running loads in kW: AC + lighting + sound + catering.
- Divide the total by 0.8 to get KVA, then add 25% for starting current and hot weather.
Example: a 200-guest wedding — AC about 18 kW + lighting 4 + sound 5 + catering 6 = 33 kW. Dividing by 0.8 gives about 41 KVA, and with the 25% margin the need is around 52 KVA — so the right choice is a 60 KVA generator, not 40 and not 100. Golden rule: run the generator at 60–80% of its rating; below that is waste, above that risks a blackout mid-celebration.
One large generator or two?
For a regular wedding, one correctly sized generator with support on call is usually enough. For large weddings, the smarter setup splits the load across two units: one for AC and one for everything else — or a main unit plus a smaller standby covering essentials (lighting and sound) if the main one fails. A wedding night happens once; backup is cheaper than any failure.
Silent or open for a wedding night?
If the wedding is at a villa, in a residential area, or the tent sits close to the guests, a silent (canopy) generator is usually the right choice: far less noise and a cleaner look in photos. Open units suit open sites far from housing. Either way, place the generator on level ground as far from the tent as practical — it reduces both noise and diesel exhaust.

Checklist before you book
- Fix the guest count and AC tonnage with your tent contractor before ordering the generator.
- Make sure the size comes from actual loads, not guesswork.
- Choose a silent unit if the venue is residential or the tent is close.
- Ask whether delivery, installation and distribution cables are included in the rental.
- Confirm the fuel tank covers the whole event with reserve (typically 8–10 hours on the built-in tank).
- Agree on early delivery and a test run under real load before the event.
- Ask about the backup plan: an attendant technician or 24/7 support with fast swap.
- Check the placement spot: level, ventilated, and away from guest walkways.

Bottom line
A wedding generator size is not a number you guess: your AC is the starting point, and total load ÷ 0.8 plus 25% is the shortcut to the right figure. At Halab Al Shahba we rent silent and open generators from 15 to 1500 KVA with delivery and installation anywhere in the UAE, and we help you calculate the load before booking. Browse our rental generators or contact us with your guest count and AC tonnage, and we will recommend the right size.
FAQ
How many KVA does a 300-guest wedding need?
Usually around 100 KVA, assuming roughly 15 tons of AC plus typical sound, lighting and catering. The final figure depends on the actual AC equipment list, so we prefer calculating the load before confirming a booking.
Is a silent generator necessary for weddings?
If the wedding is at a villa, in a residential area, or the tent is close to where guests sit, yes, usually. Silent units cut noise dramatically and protect the atmosphere of the event, while open units are fine for open sites away from housing.
How many hours does a generator run on one tank?
Typically 8 to 10 hours on the built-in tank at medium load — enough for a full event in most cases. For long weddings or high loads we arrange extra diesel reserve from the start.
Are delivery and installation included in the rental?
Yes, we deliver from our Sharjah yard and install at your site in any emirate. When booking, ask about distribution cables and temporary distribution boards if the tent is far from the generator placement point.
What if the generator fails during the event?
Choose a company with 24/7 technical support and a clear backup plan. For large weddings we recommend a standby unit for the essentials or splitting loads across two generators, so the whole event never stops over one sudden fault.
