This guide explains how to calculate your power requirement, estimate battery capacity, and choose the right inverter based on your energy needs.
How to Calculate Your Power Requirement
Selecting the correct backup system starts with understanding your total electrical load and the number of hours you require backup power.
- Step 1: Identify Your Appliances Make a list of the appliances you want to operate during a power outage and note their wattage.
- Step 2: Calculate Total Load Add the wattage of all appliances that will run simultaneously.
- Step 3: Determine Backup Duration Decide how many hours of backup power you require.
- Step 4: Calculate Energy Requirement Energy Requirement (Wh) = Total Load (W) × Backup Hours
This calculation helps determine the battery capacity needed for your application.
Example 1: Home Power Backup Calculation
Appliances Used During a Power Cut
| Appliance | Quantity | Wattage | Total Load |
|---|---|---|---|
| LED Lights | 5 | 10W | 50W |
