如何使用这个计算器
根据太阳能板和控制器的规格填写电压、电流及最低温度。天气变冷时，太阳能板电压可能升高。
计算方法
Cold Voc = module Voc × series count × [1 + (Voc coefficient / 100) × (minimum temperature − 25°C)]. Design PV short-circuit current = Isc × parallel count × margin factor. MPPT output estimate = rated array watts ÷ minimum battery voltage × margin factor. PWM current estimate = parallel Isc × margin factor.
使用结果之前
This checks selected limits, not full compatibility. Verify manufacturer maximum PV short-circuit current, input operating current, MPPT range, hot-weather string Vmp, startup overhead, allowed PV wattage and charge-current limits. PWM requires a battery-matched array; excess panel voltage does not convert to extra current. Margin is a planning assumption, not a code certification.
Can I choose a controller using output amps alone?
No. Its PV voltage, PV current, operating window, array power and battery charging specifications must also match.
