Key Formulas
Purpose
Formula
Example
Energy Consumption (Wh)
Watts × Hours
60W × 4 hrs = 240 Wh
Battery Capacity (Ah)
Watt-hours ÷ System Voltage (V)
240 Wh ÷ 12V = 20 Ah
Inverter Size (W)
Total Watts × 1.25 (for safety margin)
300W × 1.25 = 375W → Use 400W inverter
Total Load Power (W)
Sum of all appliance watts to be used at once
Light (10W) + Fan (75W) = 85W
Runtime (hrs) of Battery
(Battery Ah × Voltage) ÷ Total Load (W)
(100Ah × 12V) ÷ 240W = 5 hrs
