蓄电池续航时间、安时容量与逆变负载计算器
利用 T = (C_Ah × V × η) / P_load 计算备用电源续航小时数、电池安时容量 (Ah)、标称电压、转换效率或负载功率。
Continuous operating duration in hours
Rated charge capacity in Amp-hours
DC bus voltage (12V, 24V, or 48V)
Combined usable fraction in percent (LiFePO4 ≈ 85%, AGM ≈ 45%)
Connected device power draw in Watts (switch unit to kW)
分步代入计算过程
Battery bank backup runtime T (in hours) equals total nominal Watt-hour energy (C_Ah × V) scaled by usable depth-of-discharge & inverter efficiency η, divided by continuous load power P_load.
常见参考标准值
200 Ah × 12.8 V = 2,560 Wh nominal energy
