Example of Using the Generator Size Calculator
Let’s say you want to power the following appliances at home:
- Refrigerator: 700 Watts
- LED Lights (10 bulbs, 10 Watts each): 100 Watts
- Laptop: 50 Watts
- Fan: 60 Watts
Step 1: Add total wattage
700 + 100 + 50 + 60 = 910 Watts
Step 2: Enter hours of use
Assume these appliances will run for 8 hours per day.
Step 3: Click Calculate
Results:
- Recommended Generator Size: 1,138 Watts (910 x 1.25)
- Estimated Daily Energy: 7,280 Wh (910 x 8)
This ensures you select a generator that can safely power all appliances without overloading.
