Backup for Food Trucks
Quiet backup for POS, lighting, refrigeration support and service continuity when generator use is noisy, restricted or overkill.
Problem to solve
- Outdoor trading depends on POS, menu displays, lighting and refrigeration.
- A generator may be too loud for customer-facing areas or not allowed in some event spaces.
- Cooking appliances are usually high-load; treat them separately from essential service backup.
Typical consumption
| Load | Typical watts | Planning note |
|---|---|---|
| POS / card terminal | 20-60W | Continuous |
| Menu display / tablet | 30-100W | Continuous |
| LED lighting | 50-180W | Can be reduced |
| Fridge / cooler | 120-350W average | Compressor cycles |
| Water pump | 40-120W | Intermittent |
| Cooking equipment | 1000-3000W+ | Separate review |
Autonomy and recommended solution
| Level | Load range | What it covers | Recommended solution | Runtime guide |
|---|---|---|---|---|
| Essential | 250-500W | POS, lighting, router/hotspot, one cooler | SOLIX F2000 class | 4-7h typical |
| Advanced | 500-900W | Multiple coolers, lighting and service electronics | SOLIX F3800 class | 5-9h typical |
| Event Day | 900W+ | Long service window with several critical loads | F3800 + solar / assisted proposal | Depends on duty cycle |
Technical notes before buying
- Use battery power for quiet critical loads and keep fuel generator only for cooking or very high loads if needed.
- Solar helps between service windows, but shaded festival areas reduce real production.
