| Printer | 50-100W |
Add a 20-30% buffer to account for power spikes and future expansion. Remember, VA (Volt-Ampere) ratings are typically higher than wattage ratings.
B. Evaluating runtime needs
Determine how long you need your equipment to run during a power outage:
- Short-term (5-15 minutes): For safe shutdown
- Medium-term (30-60 minutes): To ride out brief outages
- Long-term (1+ hours): For critical operations
Longer runtimes require larger battery capacity, increasing UPS size and cost.
C. Considering scalability options
For growing businesses, scalability is key:
