Understanding Your Power Needs

Power Calculation Guide

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