What Is a Home Inverter?
A home inverter is a backup power system that automatically supplies electricity from a battery whenever there is a power outage.
A typical inverter system consists of:
- Inverter
- Battery
- Charging Circuit
- Protection System
When electricity is available, the inverter charges the battery.
When power fails, it instantly converts DC battery power into AC electricity and supplies power to your appliances.
Why Should You Buy a Home Inverter?
A quality inverter provides several benefits:
- Continuous power during outages
- Protection for sensitive electronics
- Comfortable living without interruptions
- Reliable backup for work-from-home users
- Better productivity
- Protection against voltage fluctuations (in premium models)
Step 1: Calculate Your Power Requirement
Before buying an inverter, calculate the total wattage of the appliances you want to run.
Example:
| Appliance | Power |
|---|---|
| 4 LED Bulbs | 40W |
| 3 Ceiling Fans | 225W |
| Television | 100W |
| Wi-Fi Router | 15W |
| Laptop | 70W |
Total Load = 450 Watts
Always add a 20–25% safety margin.
Recommended Load:
450W + 25%
≈ 560 Watts
Step 2: Choose the Right Inverter Capacity
Home inverters are rated in VA instead of Watts.
Approximate selection:
600VA
Suitable for:
- 2 Fans
- 3 Lights
- Router
- TV
900VA
Suitable for:
- 3 Fans
- 5 Lights
- TV
- Wi-Fi
- Laptop
1100VA
Ideal for most Indian families.

Step 3: Choose the Right Battery
The battery determines backup time.
Common capacities include:
- 100Ah
