如何使用這個計算工具
填寫同時運轉的負載和啟動瞬間的總負載。挑選逆變器時，要一起核對kW、kVA和啟動功率可維持的時間。
計算方法
Continuous kW = load × (1 + headroom) ÷ 1,000. kVA = continuous kW ÷ power factor. Required peak rating = greater of total startup load and continuous requirement.
使用結果之前
Choose an inverter that meets BOTH its continuous kW and kVA ratings, and the peak rating for the specified duration. PV input voltage/current limits, phase, battery discharge capability and charging power require separate checks.
Is a 5 kVA inverter always 5 kW?
No. Its rated output power factor and manufacturer specifications determine its usable continuous watts.
