FAQ

Q: How accurate is the runtime calculation?

A: The calculator provides theoretical estimates. Actual runtime may vary by ±20% depending on factors like battery condition, temperature, and load characteristics.

Q: Should I always choose the highest efficiency UPS?

A: Not necessarily. Consider:

• Application requirements
• Cost considerations
• Power quality needs
• Maintenance capabilities

Q: How do I account for future growth?

A: Add 30-50% to your current load calculations for future expansion. Consider modular UPS systems for scalability.

Q: How often should I replace batteries?

A: Typically:

• 3-5 years for standard VRLA batteries
• 8-10 years for premium batteries
• When capacity falls below 80%
• Based on manufacturer specifications

Q: Why does actual runtime differ from calculated?

Common factors include:

• Battery age and condition
• Operating temperature
• Load variations
• Power factor differences
• System maintenance

Q: How do temperature changes affect runtime?

A: For every 10°C increase above 25°C:

• Battery life typically halves
• Capacity temporarily increases ~5%
• Long-term degradation accelerates

Q: Can I connect multiple UPS units together?

A: Yes, but consider:

• Load balancing requirements
• Synchronization needs
• Maintenance complexity
• Control systems integration
