With frequent load shedding in Pakistan, a UPS is essential. This guide helps you choose the right one.
Step 1: Calculate Your Load
| Appliance | Wattage |
|---|---|
| Ceiling Fan | 70-80W |
| LED Bulb | 9-15W |
| Energy Saver | 20-30W |
| LED TV (32") | 50-80W |
| WiFi Router | 10-20W |
| Laptop Charger | 60-90W |
Step 2: Choose UPS Capacity
- 1000VA (600W): 3-4 fans + lights
- 1500VA (900W): 5-6 fans + lights + TV
- 2000VA (1200W): Whole room backup
- 3000VA (1800W): Multiple rooms
Step 3: Choose Battery
- Dry Battery: Maintenance-free, shorter life (2-3 years)
- Tubular Battery: Longer life (4-5 years), requires water top-up
- Lithium: Longest life, lightweight, most expensive
Backup Time Formula
Backup Hours = (Battery AH × Battery Voltage × 0.8) ÷ Load Watts
Example: 200AH × 12V × 0.8 ÷ 500W = 3.8 hours
