Power Supply Generators (From Lower to Heavy Load)
Social & Corporate Events Management
Overview
Power supply generators are essential for providing reliable electricity at events, ensuring that lighting, sound systems, catering equipment, and other electrical devices function without interruption. Choosing the right generator depends on the event size, power requirements, and environmental considerations.
Key Generator Specifications for Events
Power Output (kW/kVA)
Fuel Type
Noise Level (dB)
- Small Events (50-100 people): 5–20 kVA (e.g., food stalls, small concerts, weddings)
- Medium Events (100–500 people): 20–100 kVA (e.g., outdoor festivals, corporate events)
- Large Events (500+ people): 100–500+ kVA (e.g., concerts, sports events, exhibitions)
- Diesel Generators: Most common for events; fuel-efficient and durable.
- Petrol Generators: Smaller, portable units for low-power needs.
- Gas (LPG/CNG) Generators: Quieter and cleaner but less common.
- Solar/Battery Generators: Eco-friendly but limited to low-power applications.
- Silent/Canopy Generators (60–75 dB): Ideal for weddings, conferences, and indoor events.
- Standard Open-Frame (75–90 dB): Suitable for construction sites or loud outdoor events.
Phase Type
Runtime & Fuel Efficiency
Portability & Size
- Single-Phase (220–240V): For small equipment like lights, laptops, and sound systems.
- Three-Phase (380–415V): Needed for heavy-duty equipment (large sound systems, industrial kitchens).
- 8–24 hours on a full tank (varies by load).
- Automatic voltage regulation (AVR) ensures stable power for sensitive electronics.
- Trailer-mounted generators: For large events, easy transport.
- Portable wheeled units: For small to medium events.
Common Uses in Events
Choosing the Right Generator for Your Event
- Sound & Lighting Systems (PA systems, DJ equipment, stage lights)
- Catering & Food Stalls (refrigerators, cooking equipment, coffee machines)
- AV & Projection Systems (screens, projectors, live streaming)
- Charging Stations (phones, cameras, laptops)
- Emergency Backup Power (in case of grid failure)
- Calculate Total Power Requirement (sum of all devices + 20% buffer).
- Consider Noise Restrictions (use silent generators for indoor/quiet events).
- Check Fuel Availability (diesel is most common for large events).
- Ensure Safety (proper grounding, ventilation, and certified electricians).
- Rental vs. Purchase (short-term events usually rent generators).
Example Setup: 300-Person Outdoor Wedding
- Generator Size: 30–50 kVA silent diesel generator.
- Power Needs: Sound system (5 kW), lighting (3 kW), catering (10 kW), misc. (2 kW).
- Runtime: 12+ hours with fuel refill options.
Safety & Best Practices
- Place generators away from guests to reduce noise and fumes.
- Use weatherproof enclosures for outdoor events.
- Hire a qualified electrician for setup and monitoring.
- Follow local regulations on generator use and emissions.
Please provide details about your event:
- Event Type (e.g., wedding, concert, festival, corporate meeting, food market)?
- Estimated Attendees (50, 100, 500, 1000+)?
- Key Equipment Needed (e.g., sound system, LED screens, food trucks, stage lighting)?
- Location (indoor, outdoor, remote area with no grid power)?
- Noise Restrictions (does it need to be silent/super quiet)?
Example Scenarios & Recommendations:
1. Small Outdoor Wedding (100 Guests)
- Power Needs: Sound system (2 kW), string lights (1 kW), catering (3 kW), phone charging (0.5 kW).
- Total Load: ~6.5 kW + 20% buffer = 8 kW (10 kVA recommended).
- Best Generator: 10 kVA Silent Diesel Generator (60–70 dB, 8–12 hrs runtime).
2. Medium Music Festival (500 People)
- Power Needs: Stage (10 kW), food stalls (15 kW), lighting (5 kW), vendors (5 kW).
- Total Load: ~35 kW + buffer = 42 kW (50 kVA recommended).
- Best Generator: 50–100 kVA Diesel Trailer Generator (with AVR for sound equipment).
3. Corporate Conference (200 People, Indoor)
- Power Needs: Projector (1 kW), laptops (2 kW), LED lighting (3 kW), AC (10 kW).
- Total Load: ~16 kW + buffer = 20 kW (25 kVA recommended).
- Best Generator: 25 kVA Super-Silent Canopy Generator (<65 dB for minimal disruption).
