Backup for Cafes
Keep payment, internet, lighting and essential refrigeration online during short outages, without oversizing for machines that should be handled separately.
Problem to solve
- Card payments, POS, router and ordering systems stop immediately when power fails.
- Fridges and display coolers can tolerate short interruptions, but repeated outages affect stock and food safety.
- Coffee machines, ovens and grinders create high peaks and should not be mixed into an essential-only backup without checking real wattage.
Typical consumption
| Load | Typical watts | Planning note |
|---|---|---|
| Router / firewall | 10-30W | Usually continuous |
| POS / tablet / card terminal | 20-80W | Continuous during service |
| LED counter lighting | 40-150W | Can be reduced in emergency mode |
| Small fridge / display cooler | 120-300W average | Compressor cycles; startup peak can be higher |
| Coffee machine | 1000-3000W+ | Manual confirmation recommended |
Autonomie
| Level | Load range | What it covers | Recommended solution | Laufzeit |
|---|---|---|---|---|
| Essential | 250-450W | Payments, router, POS, reduced lighting, one small fridge | 2 kWh station class | 4-7h typical |
| Advanced | 450-900W | Several payment points, lighting, fridge/cooler support | 3-5 kWh high-capacity station class | 4-8h typical |
| Full Backup | 1000W+ | Coffee equipment or several cooling points | Assisted proposal | Manual load review |
Technical notes before buying
- Separate “essential service” from “full operation”. Keeping payments and cooling alive is realistic; running the full coffee bar may need a larger project.
- Ask for the appliance label or a photo of the watts/amps plate before confirming coffee machines, ovens or ice machines.
