Determines inverter capacity to handle peak loads from solar or battery systems. Prevents inadequate power and equipment damage.

ステップバイステップガイド

  1. 1Sum peak simultaneous power consumption (watts)
  2. 2Account for inrush current (motors 3-5× running)
  3. 3Add 25-50% capacity headroom for growth
  4. 4Select inverter rated 120-150% of peak load

解いた例

入力
2000W peak load
結果
3000W inverter

避けるべきよくある間違い

  • Using average power instead of peak power
  • Not accounting for motor inrush current

よくある質問

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.
