Portable Generators for Outdoor Events: What to Look For
Outdoor events, from music festivals and weddings to corporate gatherings and food fairs, rely heavily on power. A reliable portable generator ensures smooth operations, from lighting and sound systems to catering and entertainment. Choosing the right generator is crucial to avoid power failures and unexpected issues. In this guide, we’ll cover everything you need to consider when selecting a portable generator for outdoor events.
Why Do You Need a Portable Generator for Outdoor Events?
Hosting an event outdoors presents unique challenges, particularly when it comes to power supply. Many event venues, such as open fields, beaches, or temporary setups, lack access to electrical grids. Portable generators provide a self-sufficient power solution, ensuring your event runs seamlessly. They are essential for:
- Powering sound and lighting systems
- Running food stalls and catering equipment
- Charging essential devices and communication tools
- Ensuring backup power in case of an outage
Key Factors to Consider When Selecting the Right Portable Generator
Determine Your Power Requirements
The first step in choosing a portable generator is calculating your power needs. This depends on the type and number of devices you’ll be running.
- List all equipment – Identify everything requiring power, from stage lights and microphones to fridges and coffee machines.
- Check wattage ratings – Each appliance has a starting (surge) wattage and a running wattage. Ensure your generator can handle the peak power demand.
- Factor in extra capacity – Always choose a generator with at least 20% more power than your estimated usage to avoid overloading.
- Example Power Consumption:
- PA system – 1.0 kVA
- LED lighting – 0.5 kVA
- Food warmers – 1.5 kVA
- Coffee maker – 0.8 kVA
- Total: 3.8 kVA (Opt for a generator with at least 4.5 kVA to allow for fluctuations)
Choose Between Inverter vs. Conventional Generators
Portable generators come in two main types: conventional and inverter.
- Inverter Generators – Ideal for events requiring clean, stable power. They produce low noise levels, making them perfect for weddings, speeches, or music performances.
- Conventional Generators – More powerful and budget-friendly but tend to be noisier. Best suited for large-scale events where sound isn’t a concern.
Consider Noise Levels
Noise pollution can ruin an event’s ambiance. A loud generator could interfere with speeches, music, or guest conversations. Look for generators with low decibel ratings (dB):
- Under 60 dB – Suitable for weddings, corporate events, and quiet settings.
- 60–75 dB – Moderate noise level, works for fairs and markets.
- Above 75 dB – Best for industrial use or large festivals with loudspeakers.
Tip: Position the generator away from the main event area and use sound barriers if needed.
Fuel Type: Petrol, Diesel, or Dual-Fuel?
Choosing the right fuel type affects cost, efficiency, and convenience:
- Petrol Generators – Readily available fuel, but shorter run times and higher consumption.
- Diesel Generators – More fuel-efficient with longer run times but often louder.
- Dual-Fuel Generators – Offer flexibility to switch between petrol and LPG, ensuring fuel availability.
For long-duration events, diesel generators are often the best choice due to their efficiency and durability.
Portability and Ease of Transport
Outdoor events require a generator that’s easy to move and set up:
- Wheel kits and handles – Essential for manoeuvring across different terrains.
- Compact and lightweight designs – Ideal for quick deployment at small-scale events.
- Heavy-duty units – May require transport assistance but offer more power for large venues.
Run Time and Fuel Efficiency
The generator’s run time dictates how long it can operate without refuelling. Consider:
- Longer run times for full-day events (8+ hours per tank is ideal).
- Fuel efficiency features such as eco-mode, which adjusts power output to demand.
- Large fuel tanks to minimise refuelling interruptions.
Safety Features and Compliance
Safety is crucial when operating portable generators at events. Look for models with:
- Automatic shutoff – Prevents damage when fuel or oil levels are low.
- Circuit breakers – Protects equipment from power surges.
- GFCI outlets – Essential for outdoor use to prevent electrical hazards.
- Weather protection – Some models come with built-in covers to handle rain or dust.
Always ensure the generator meets local safety regulations and emissions standards.
Connectivity and Outlet Options
Generators come with different outlet types. Ensure yours supports:
- Standard 230V outlets – For general event equipment.
- USB ports – Useful for charging small devices.
- Multiple sockets – Avoid overloading by distributing the load efficiently.
Some advanced models even feature remote start options, allowing you to turn the generator on and off without manual intervention.
Budget Considerations
Generators vary widely in price. When deciding on your budget, balance cost with reliability and performance.
- Low-budget (<£500): Best for small gatherings and light loads.
- Mid-range (£500-£1,500): Good for medium-sized events with multiple appliances.
- High-end (£1,500+): Ideal for large-scale events requiring heavy-duty power.
