Determines inverter capacity to handle peak loads from solar or battery systems. Prevents inadequate power and equipment damage.
Водич корак по корак
- 1Sum peak simultaneous power consumption (watts)
- 2Account for inrush current (motors 3-5× running)
- 3Add 25-50% capacity headroom for growth
- 4Select inverter rated 120-150% of peak load
Worked Examples
Инпут
2000W peak load
Резултат
3000W inverter
Common Mistakes to Avoid
- ✕Using average power instead of peak power
- ✕Not accounting for motor inrush current
Frequently Asked Questions
What happens if inverter is undersized?
Insufficient power for peak loads, brownouts, equipment damage, and automatic shutoff.
What if inverter is oversized?
Wastes money; minor efficiency loss; better to slightly oversize than undersized.
