UPS/Inverter Backup Time Calculator

Calculator

Backup Time: -- hours

Formula

Backup Time (hrs) =
Battery Capacity × Battery Voltage × No. of Batteries × Efficiency
Load Power
Where:
- Battery Capacity = in Ah
- Battery Voltage = in Volts
- Number of Batteries = connected in inverter
- Efficiency = % (e.g., 85%)
- Load Power = total watts of devices
