Start with the number of AC units
Air conditioners are the biggest load in a camp. Each tent AC needs about 2.5 kW and draws more at start-up. Then add the kitchen, lighting and fridges.
Small camp
≈ 15 kVA
One or two tents, one AC unit, lighting, a fridge and phone charging.
Family camp
≈ 30 kVA
Three air-conditioned tents, a kitchen, a water pump and full yard lighting.
Commercial camp
≈ 60 kVA
Six air-conditioned tents, two kitchens, display fridges, a sound system and wide-area lighting.
Sizes are estimates worked out with the same method as the load calculator. We confirm the size with you before booking.
Where should the generator go?
As far from tents and seating as the cable allows, on firm level ground, with the exhaust pointing away from people. The canopy cuts the noise and distance does the rest.
Safety rules
- Place the generator in the open air, away from tents, with the exhaust pointing away from seating and sleeping areas
- Never run a generator inside a tent or enclosed space: carbon monoxide cannot be seen or smelled
- Switch off and let the unit cool before refuelling
- Run cables away from walkways and protect them from vehicles and water
- Do not overload the generator, and start air conditioners one after another
- Keep a fire extinguisher near the generator and the kitchen
Diesel: how much do I need?
A 30 kVA unit uses about 4.9 litres an hour at 75% load. For a 12-hour night allow about 60 litres, less if the load is light.

Common questions
Is a small portable generator enough for a camp?
For lighting and charging only, yes. If the camp has AC units or an electric kitchen you need a diesel generator of 10 kVA or more.
