We all find power cuts frustrating, especially when we are dealing with sweltering
summers or freezing winters. Unexpected outages can keep us in the dark (literally!) and stop our online tasks,
appliances, and whatnot. Inverters are an invention that helps humanity deal with such scenarios with ease. Which
inverter to choose as your personal power savior that can keep all important things running smoothly is a question
that arises. A right home inverter buying guide eases up the brainstorming.
This power
inverter buying guide walks you through everything you need to know
before buying an inverter for home or workspace. Read on to explore the key inverter buying tips.
Why Do You Need an Inverter?
We are all no fans of frequent power cuts as they take away the basic need for a fan.
Instances apart, they simply disorient daily life. Inverters are lifesaving backup power solutions. They are
designed to store electricity and supply it to your appliances later when there are power cuts or grid failures.
These appliances are –
- Noiseless
- Low-maintenance
- Eco-friendly
But to choose the right one, you need to understand a few things. Further sections have
a step-by-step inverter buying guide for home any other place where you would need an inverter.
Step 1: Know Your Power Requirements
First things first, you have to calculate your total power consumption during an outage.
Let us see how:
Make a list of appliances you want to run when the power goes out and sum up
their wattages.
Appliance | Power (Watts) |
2 Tube Lights | 60 |
1 Ceiling Fan | 70 |
2 CFL Bulbs | 40 |
Total | 170 W |
Step 2: Understand Inverter Battery Basics
The inverter is just one part of the system. There is a inverter
battery also involved where the main action happens. So, you need to
know a few things there:
The battery capacity, which is given in Ampere-Hour (Ah). It shows how long your
inverter can run the appliances. You can calculate the battery size as follows:
Backup time (in hours) × Power requirement (in watts) = Watt-hours
Convert Watt-hours to Ah using:
Ah = (Watt-hours / Battery Voltage)
See this example:
If you need 170 watts for 6 hours, you will need roughly a 150 Ah battery (assuming
12V).
Step 3: Choose the Right Inverter Capacity (VA Rating)
Now, you can calculate the VA rating of your inverter, which is inverter
capacity.
Use this formula:
VA = Power Requirement (Watts) ÷ Power Factor
Note: The Power Factor for homes is typically 0.7 to 0.8
See this Example:
VA = 170 W ÷ 0.7 = ~243 VA
Round it up to 250 VA to avoid overloads.
Tip: Always pick an inverter with a
slightly higher capacity than your actual need for longer life and better performance.
Step 4: Square Wave vs. Pure Sine Wave Inverters
Type | Description | Best For |
Square Wave | Basic, budget-friendly | Basic appliances only |
Pure Sine Wave | Smooth, stable power, safer | TVs, refrigerators, PCs |
Tip: Always opt for Sine Wave inverters if
you want to protect sensitive electronics and ensure higher efficiency.
Step 5: Match Inverter Size to Home Type
This quick cheat sheet will help you match your home with the right inverter
setup:
Home Type | Inverter Capacity | Battery Capacity | Appliances Covered |
Small Apartment | 250 VA | 100 Ah | Lights, fan, TV |
Medium Home | 500 VA | 150–200 Ah | Refrigerator, multiple fans, lights |
Large Home | 800–1000 VA | 200 Ah or more | Water pumps, A/Cs, refrigerators, multiple rooms |
Bonus Tip: Check Home Wiring Compatibility

Before finalizing your inverter, check your home’s wiring. They
must be compatible with an inverter setup. Improper or non-suitable wiring can damage your appliances and your
inverter as well. Get expert consultations to help with installation and compatibility checks.
