如何使用这个计算器
填写同时运行的负载和启动瞬间的总负载。选逆变器时，kW、kVA和能维持多久的启动功率都要核对。
计算方法
Continuous kW = load × (1 + headroom) ÷ 1,000. kVA = continuous kW ÷ power factor. Required peak rating = greater of total startup load and continuous requirement.
使用结果之前
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.
