How To Choose The Right Power Inverter?

by Brian Beltran

The inverter is the device that delivers power backup through the battery. Planning to get the best power inverter for a home? But the tricky part is, most of us just don’t know how to choose the right power inverter. It is because of too many options in the market and not knowing much about the power requirement.  With the right inverter and battery, you can enjoy a smooth power backup in your home appliances. So, it is better to do some homework and understand the basics of the inverter you want. Let us help you with your homework.

Types of Power Inverter

AC power is the essential power supply for all industrial, residential, and commercial use. But the problem is AC power can’t be stored for any future use. By converting the AC power to DC, the power can be stored and used for any needs. The power inverter works as a power electronics device that converts DC voltage to AC voltage. This converting process comes in variation, and for this, the inverter comes in different types. Now we will look into the inverter types and understand how it plays with the power supply:

How To Choose The Right Power Inverter?

Output individual type:

You will find three types of inverters in output individual. They are:

Square wave inverter:

This inverter type is the simplest and least used inverter. The inverter outputs square waveform by converting the DC to phase fluctuating AC. So, you can tell the AC signal is not pure. If you use this inverter for your home appliances, they will get damaged fast.

Altered sine wave inverter:

This inverter tries to output the smooth sine wave, but the power phase-shifting gets pause. So, the power converting doesn’t get a stable AC signal. It is a complex one but not more than the sine wave inverter.

Sine wave inverter:

Lastly, the most complex but efficient inverter is the sine wave inverter. With it, your home equipment will get grid power like waveform. The sine wave signal provides a proper power supply for all devices by making the least damage. Though this inverter is pricey, it is generally used in commercial and residential uses.

Load type:

As the AC power comes in two types- single phase and three phases, so the load type inverter comes in two:

Single-phase inverter:

The single-phase load runs in a single-phase inverter. This inverter works in two ways, single-phase half-bridge inverter and full-bridge inverter.

In a half-bridge inverter, two (S1 and S2) thyristors and two (D1 and D2) are used, and at a time, one switch is in transmission. On the other hand, the full-bridge inverter uses four (S1, S2, S3, S4) thyristors and four (D1, D2, D3, D4), and transmission is done with two switches.

Three-phase inverter:

The three-phase inverter supplies AC power in three-phase loads for industrial uses. In this phase, six diodes (D1, D2, D3, D4, D5, D6) and six thyristors (S1, S2, S3, S4, S5, S6) are used and the transmission time is divided into two types. One is a 120-degree mode where the ON switch works on 120 degrees, and the OFF switch works on 240-degree mode. And the other one is a 180-degree mode where the transmission time for the thyristors is 180-degree.

Note: Here, in this article, you learn about the types of power inverter available in the market, but if you want to know which size of inverter you may need then read this article also that we wrote on what size power inverter do I need?

How To Choose The Right Power Inverter?

Choosing the best 2000-watt inverter or best 3000-watt inverter is a tough job, especially for the new users. Because the new users don’t know what to consider while purchasing the right power inverter, in this part, I think all types of users will get a clear picture of the essential things that an inverter should have to meet all the requirements.

How To Choose The Right Power Inverter

Power usage:

Before going to purchase an inverter, calculate how much power will your devices need. Just calculate the power requirement of your home appliances. This calculation will help you to pick the right power capacity inverter.

Inverter output:

There are different types of inverter that allows different outputs. Know which waveform is perfect for your home appliances, or else you will face great loss.

Battery type and capacity:

The power source of the inverter is the battery. So, the battery type and the capacity are important as the inverter can provide a smooth power supply depending on it. Among the batteries, the tubular battery is the best option. This battery promises capacity and charging efficiency for an inverter.


With an inverter, the common problem the user’s faces are the installation problem. Maximum users end up in contact with technicians to install the inverter. This makes the installment process costly and time-consuming. Thank god, there are now some inverters in the market that comes with user-friendly features to help the installation fast and free.  Look for the inverters that help make your installing task simple and cost-free.


The inverter capacity is based on the efficiency of the inverter. If you want an inverter that will help you to run the appliances like drill machine, refrigerator, air conditioner, then choose the inverter with power capacity up to 4000W. And if you want an inverter to run the small devices like a notebook, laptop, or mobile devices, then 1500W power capacity inverter is just enough for you.

Safety features:

While choosing the inverter, the safety features should be considered on the top. Be the inverter is for your truck or home, the inverter has to promise safe use. Don’t compromise with safety at any cost. Pick the inverter that protects from over-voltage, short-circuiting, overloading, and under-voltage. It is important.

Cost range:

Don’t think that the inverters come with a high price. There are hundreds of inverters in the different price ranges. You can go for per your price range, and power requirements as small inverters can meet your power requirements.


As there are different branded inverter in the market, go for the one that promises immediate support whenever you want.

Why Should You Buy A Power Inverter?

In some countries, power cuts problems are getting severe for various reasons. In this section, I will talk about the benefits of using a power inverter.


With a power inverter, you will not have to take the extra hassle to start or stop or oiling or maintenance, etc. such things. It will start automatically in any situation without creating any noise. You will not face any breakdowns or power-consuming problem with an inverter. The inverter provides efficient power with less maintenance.

Some inverters come with solar systems. With this feature, you will not have to face any problem while you are on a trip or camping. With power, you can operate your devices and small home appliances easily. The versatile features make the inverter a hero for your devices and home appliances.

Note: In the above section you learn about why you should buy a power inverter but all of its benefits you can achieve only when you able to choose the best power inverter for home. Read the following article to know about this more.

Frequently Asked Questions

Here is the answer to your questions that you frequently asked us. We hope you will get a solution that you were looking for a while.

Can inverter save electricity?

Yes, but I will say the inverter consumes power while converting process.

Does inverter increase electricity bills?

Technically, no. Because the inverter only uses storage power when a power outage happens.

How many watts does an inverter use?

As the inverters come from 50 watts to 50.000 watts, the inverter uses the watts per the time and surge use of devices and appliances.

Can we switch off inverter?

yes, when the batteries are fully charged, you can switch off the inverter.

Does an inverter use power if nothing is plugged in?

yes, the inverter use power even we don’t have anything plugged in as it needs 8-10% more power to run.

Final Remarks

I think you now have clear information about how to choose the right power inverter properly. With the right power inverter, you can ensure a comfortable life. If you live in a place where power outage is the problem, then purchase a high-quality power inverter to tackle the problem. With an inverter, you can enjoy a long road trip or a camping tour without any issues of charging devices.
