如何使用這個計算工具
先決定備援家電和需要供電幾小時。計算會考量可用電量與轉換損耗，電池標示容量並非全部都能用。
計算方法
Nominal kWh = load watts × hours ÷ (1,000 × DoD × efficiency). Bank Ah = nominal kWh × 1,000 ÷ nominal bank voltage. Enter 24 hours for one day of continuous backup.
使用結果之前
Ah is capacity at the stated bank voltage, not the sum of series-connected battery Ah ratings. Allow separately for age, temperature, peak discharge and recharge time.
Do batteries in series add amp-hours?
No. Series connections add voltage while Ah stays the same; parallel strings add Ah at the same voltage.
