Power outages happen, and outdoor venues often lack reliable power. For destination wedding streaming, backup power prevents catastrophic failure. Without it, loss of power means loss of livestream. Understanding power requirements and backup solutions is crucial.

Power Requirements for Streaming Equipment

Typical Streaming Setup Power Draw

  • Laptop/streaming computer: 50-100W typical
  • Bonded cellular modem: 20-30W
  • Router/WiFi equipment: 10-15W
  • Wireless microphone: 5-10W
  • Camera: 10-20W (if powered, not battery-operated)
  • Total system: 100-200W typical operation

Peak power during startup can spike to 200-300W. Planning should accommodate peak power demand.

Solution 1: UPS (Uninterruptible Power Supply)

How UPS Works

  • Battery-backed power supply
  • Provides immediate power if venue electricity fails
  • Sustained power for 30 minutes to several hours depending on capacity
  • Time to transition to generator if needed, or complete ceremony if short

UPS Sizing

  • Capacity: Need 500W+ UPS for 100-200W equipment load (provides safety margin)
  • Battery runtime: 1000+ WH (watt-hour) capacity = 5-10 hours theoretical (less with 200W load)
  • Realistic duration: 2-4 hour runtime typical for wedding streaming duration

UPS Considerations

  • Large/heavy (not portable for outdoor ceremony areas)
  • Need to position near equipment (cable length limited)
  • Must remain charged before event (test 1-2 days before)
  • Monitor battery health during event

When UPS Is Appropriate

  • Venue has main power, but want protection against failure
  • Ceremony expected to last 2-4 hours (UPS duration sufficient)
  • Equipment can reach venue power supply (cables available)

Solution 2: Generators

Types of Generators

  • Inverter generators: 5-10kW, quiet (suitable for weddings), $1,500-3,000
  • Standard generators: 5-15kW, louder, $1,000-2,500 (less suitable for weddings)
  • Portable generators: Smaller, 2-5kW, $500-1,500

Generator Power Requirements

  • 200W streaming equipment needs 5-10kW generator minimum (safety margin for surge)
  • Fuel consumption: Typical 5kW generator uses ~1 gallon/hour under load
  • Runtime: Need ~2 gallons for typical 2-3 hour wedding

Generator Positioning

  • Must be outside ceremony area (noise and fumes)
  • 50-100+ meters away from venue for minimal noise impact
  • Requires long power extension cords (voltage drop concerns at distance)
  • Need shelter from weather (generators sensitive to water)

When Generators Are Appropriate

  • Outdoor ceremonies without venue power supply
  • Long ceremonies or receptions (extended power needs)
  • Venue allows generator operation (some venues restrict due to noise)

Solution 3: Combination Approach (Best Practice)

Professional destination wedding streaming often combines:

  • Primary: UPS providing immediate power if venue electricity fails
  • Secondary: Generator as extended-duration backup
  • Flow: Power loss → UPS activates → technician starts generator → system switches to generator power

This provides redundancy and extended duration with minimal complexity.

Solution 4: Battery Packs / Portable Power

Modern Portable Batteries

  • Capacity: 500Wh to 3000Wh portable batteries available
  • Examples: EcoFlow, Jackery, Goal Zero brands
  • Cost: $500-2,000+ depending on capacity
  • Duration: 500Wh battery = ~2-3 hours for 200W load

Advantages

  • Portable (can position near equipment)
  • No noise or fumes
  • Can be used for other devices (lighting, sound, etc.)
  • Scalable (multiple batteries for longer duration)

Disadvantages

  • Large, heavy units
  • Multiple units needed for longer ceremonies
  • Cost-per-hour expensive compared to generators

Power Management Strategy

Load Optimization

Reduce power requirements to extend backup duration:

  • Use laptop instead of desktop (50-100W vs 200-300W)
  • Disable unnecessary equipment (extra monitors, lights)
  • Use external antennas (reduce need for signal boosters)
  • Battery-powered camera instead of powered camera

Monitoring

  • Check UPS battery status before ceremony
  • Monitor power draw during event
  • Watch for signs of power issues (lights dimming, equipment cycling)
  • Have operator ready to switch to backup if primary fails

Venue Power Assessment

Understand what your venue actually offers:

  • Are outlets available in ceremony area, or only at buildings?
  • Can venue guarantee power during event, or are they just best-effort?
  • What's the distance from power supply to equipment location?
  • Are extension cords needed? (voltage drop over distance)
  • Is venue power on shared circuits (potential overload)?

Key Takeaways

  • Streaming equipment uses 100-200W typical, plan for 200-300W peak
  • UPS provides 2-4 hour backup, good for short outages
  • Generators provide extended power but need positioning away from ceremony
  • Combination (UPS + generator) provides best redundancy
  • Portable batteries good for smaller setups, scalable but expensive
  • Plan for venue power limitations—don't assume unlimited power
  • Test backup power before ceremony (charge UPS, verify generator start)
