Best Inverter for Home – Buying Guide

That is all for the list of the home inverters we consider the best. Now, we’ll go in-depth about all the factors you need to know about before you buy an inverter.

 

What is an inverter?

An inverter converts DC (Direct Current) into AC (Alternating Current) at any frequency or voltage. In cases where the main power goes off, the AC required to power appliances is acquired by converting DC to AC from the battery backup.

The inverter can convert the current and start using it so fast that the devices don’t even turn off during sudden power cuts. Thus, these inverters are an excellent source of backup power for home appliances. The size of the batteries for the inverter depends on your requirements, though.

You can choose inverters with a smaller battery capacity if you only need lights and fans to run. But, if you need to use the inverter as a backup for bigger appliances like TV and fridge then bigger capacity is required. Often the best refrigerators come with a design that lets them smoothly run on a home inverter. Our experts advise not more than a few big appliances on the inverter, though.

 

Types of Inverters

There are three types of inverters, based on the kind of outputs they offer. They are Pure Sine Wave inverters, Modified Sine Wave inverters and Square Wave inverters.

1. Pure Sine Wave Inverters

Pure Sine Wave inverters supply current in the most reliable and cleanest form. The pattern is like the same one offered by regular wall sockets. Its output in Sine Waveform is also identical to that of a utility supply.

These inverters work the best with all appliances, as said appliances are designed to work on Sine Wave patters only.

Besides, these inverters are the best choice for those who wish to use the inverter for powerful appliances. For instance, these inverters are really good for running powerful ones like refrigerators and TVs. They provide efficiency with little power consumption.

Sine Wave inverters can adjust voltage according to conditions. Thus, suitable for running several devices. Though these inverters are somewhat expensive, they’re good at handling heavy loads.

2. Modified Sine Wave Inverter

A modified sine wave inverter has a rougher transition period over a pure one. It takes a brief pause before it shifts phases from positive to negative.

A modified sine wave inverter works more like a square but is a little more complicated than Square Wave Inverters. Though these inverters can support many appliances, they’re often prone to hiccups. To put it briefly, they hamper the efficiency of the machines and makes them either noisy or underpowered.

Suppose you’re getting an inverter for devices with resistive loads which don’t need startup surges. In that case, they’re the right choice. These models are cheaper than Pure Sine Wave inverters.

3. Square Wave Inverters

These inverters are the most inefficient among all the other types of inverters. They create Square shaped waveforms. You can use these inverters with devices that have universal motors. Another notable disadvantage is that these inverters are very noisy.

 

Electricity consumption of the common electrical appliances

Before you go to find the best inverter for home, you should consider the amount of power you’ll need. It depends on how many appliances you need the backup for. Once you’ve figured that out, you should then calculate the total power consumption.

Here’s a table representing the average power consumption of the usual appliances.

AppliancePower Requirement (in Watts)
LED Bulb 7 Watts
CFL25 Watts
Tube Light50 Watts
Fan80 Watts
TV120 Watts
Refrigerator300-350 Watts
Mixer Grinder500-750 Watts
Induction Cooker1000-1500 Watts

Now, using the above information, we’ll give an example of how to calculate the power backup.

Suppose you want to use two LED bulbs, two Tube Lights, two Fans and one TV with the inverter. In that case, the calculation will go like this;

2×7(W)+2×50(W)+2×80(W)+1×120(W) = 394 Watts

So, to run 394 Watts worth of power, you need an inverter that can provide 450-500 Watts.

 

What’s the difference between an inverter and the UPS?

A UPS has a shorter switchover time during a power cut. The switchover time is the time the device takes to supply appliances with power when the electricity goes out.

A UPS only takes 3 to 5 milliseconds. In contrast, an Inverter takes as long as 10 to 100 milliseconds. This difference might not seem much in the paper- it isn’t if you’re just going to use it with things like fans and lights.

But, with sensitive devices like computers, the lack of power can lead to a complete shutdown. Any unsaved data will be lost. A UPS would be the best option for such situations.

The inverter has a delay because it doesn’t have an inbuilt battery, unlike a UPS, which comes equipped with one. So, it has to draw power from an external battery and then convert the current from DC to AC.

Besides, the UPS has a direct connection to appliances with plug sockets. In contrast, the inverter uses the main supply line to send power from the battery to the devices. This causes a longer delay for the inverter to work.

 

Different alternate power supply options

There are various alternate power sources to deal with very long power cuts. Below we will talk about some of them, and recommend when it’s best to use them.

1. Inverter

An Inverter stores power in DC form within a battery. When the power goes out, it will convert the stored DC power to AC and supply as needed. This alternate power source is a good option for machines like lights, fans, TVs and others. Newer inverters can sustain larger appliances like fridges and washing machines.

2. DG Sets

These devices use Diesel to produce electricity. Rather than using reserves, they generate electricity right away.

3. Solar Power

Solar Power is one of the newer and rapidly growing ways of producing power. The Solar Panel converts energy from sun rays to electricity and store that in batteries. But, if you live in somewhere with little sunlight, then this might be the wrong choice. These devices can’t handle higher load either.

 

How to select the best inverter for Home?

If you still picked an Inverter, then this part will be of great use to you. Let’s take a look at all the small but vital information you need to keep in mind.

1. Power Requirement

As we spoke of earlier, always make sure your inverter meets your power requirements. Getting an inverter won’t benefit you if you choose something underpowered. Reference the power consumption table above and calculate what you need, to get the best inverter for home.

 

2. Inverter Capacity

Generally speaking, Volt-Amp (VA) denotes inverter capacity. The total wattage usually is equal to the VA value. Yet, when it comes to Power Factor, things do not stay the same.

The efficiency of the incoming power used in the electric system determines the power factor. Although, it also referred to as the ratio of Real power to Apparent power (the Working power to the Total power).

Real power (kW) represents the amount of energy the appliances consume to work correctly. On the other hand, Reactive Power (kVAR) is the amount of power that equipment like Transformer consumes to generate magnetic fields.

In residential use, power factors are generally 0.7 to 0.8, whereas 0.7 is the safest and 0.8 is economical. VA value comes from dividing the total load in watts by the power factor. So, with that in mind, let’s take a look at an example;

300/0.8=375 VA

As models with exact 375 VA aren’t available, the next best thing would be going for an inverter of 400 or 500 VA. Besides, it’s always better to purchase an inverter that has at least a few units more capacity than the actual requirement.

 

3. Battery Size

If you pick an incompatible battery size, the inverter won’t be able to give you the best results. The capacity or battery size is measured in Amp-Hour (Ah). Ah refers to the amount of current a battery can provide for a certain period.

For instance, a 1000Ah can supply about 1000 amp current within an hour. Although, it can also provide 500 amp of current for 2 hours. Here is a formula that lets you calculate the battery size:

[VA rating of the inverter] X [use time (in hours)] / [Input voltage] = [Battery size]

Now, imagine you wish to use a 400 VA inverter for 6 hours of backup. You can calculate the required battery size this way:

400 VA x 6 Hours = 2400 Ah

“Ah” generally represents the battery size or capacity. In other words, it denotes the amount of energy the battery can store. A standard inverter battery can offer input of 12 volts. Thus, the Ah value will be:

2400VAh/12V = 200 Ah

Starting from 100 Ah, there’s an extensive range available in the market. As such, 250Ah would be the perfect battery size for our scenario.

Moreover, you should also consider the type while you choose the best inverter battery. These batteries are of three types.

  • Flat plate batteries
  • Tubular batteries
  • Maintainance free batteries

Of all the three types, the Tubular Batteries work the best with inverters. Even though they cost a little more than Flat Plate batteries, they offer long-lasting performance. When Maintenance Free Batteries can provide you with 3-4 years of use, Tubular ones can last you 6-7 years.

One more thing to note is that you should always fill the batteries with distilled or RO water often. Doing that alongside the fluid levels will make your batteries last longer.

 

4. Brands

Because of how often power cuts occur in suburban and rural areas, inverters have become essential for every homey. There are many brands which sell inverters with different features. But it is always better to buy from popular brands as the product will have convenient features, high efficiency, excellent quality, and exceptional durability.

However, while Inverters are essential, their brands don’t come up in talks. For instance, when you think of the best LED TV, you think of LG or Samsung. It might not be like that in the case of inverter brands.

So, we’ll touch upon each of the best brands briefly to let you know of their specialities. Here are some of the most reliable inverter brands:

  • Luminous– They’re known for their intelligent inverters, which also come packed with features.
  • Exide– Inverters from Exide are very heavy-duty. Aside from Inverters, Exide’s batteries are also highly durable.
  • Microtek– Microtek’s inverters are generally good, and besides that, they can also function as UPS.

 

5. Price

If the price is a concern, we’ll tell you the difference in quality between multiple prices. The inverter’s cost depends on its brand, its features and its technical specifications.

Considering that they’re more efficient with the reduced energy loss during the conversion of DC to AC, they’ll usually be more expensive than alternatives. Inverters with a higher VA rating will be even more pricey as they can handle heavy appliances like ACs or refrigerators.

In the most common situation of domestic use, inverters ranging from Rs 5000 to Rs 7000 that have standard features work well enough. Although, with smart and advanced features, the price can rise to around Rs 8000.

 

6. Warranty

Always opt for inverters that offer a good warranty. The longer the warranty, the more expensive the inverter is. However, the reduced maintenance costs as a result of the extended warranty can make up for the initial cost.

Remember, both the inverter and battery combination is going to be a long-term investment. Go for the best combination that will provide the best value for the money you spend.

How to take care of your inverter and batteries?

As a lot of the other appliances in your house depend on your home inverter, it’s vital to keep the inverter well-cared for. Here we’ll list some effective actions you can take to keep your inverter performing seamlessly.

1. Keep your inverter in a ventilated area

Keeping your home inverter in a ventilated area is going to save you a lot of trouble. Suppose you place your inverter in an area with no ventilation. Then, the heat generated will produce dew or water. Such can lead to overheating and rust. So make sure to place your inverter in a well-ventilated area.

 

2. Clean often

Dust is inevitable. You have to prevent it from making your inverter malfunction. Try to keep it free of dust and dirt stains like oil. With a cotton cloth, wipe as often as possible to ensure the surface and sides of your inverter stays free from dust.

 

3. Always keep your batteries charged

Letting the battery of your inverter run out completely will lead to its lifespan getting reduced. Thus, you should always be trying to keep it charged at all times. You’ll face unpleasant consequences if you wait for your battery to discharge completely before charging it again. So we advise you not to let that happen at all.

 

4. Change faulty batteries

If your battery gets damaged or starts malfunctioning, then don’t attempt to use it or combine with a new battery. Such could damage the whole inverter or even cause an explosion. The best thing you can do in such a situation is to get the faulty battery replaced with a new one.

 

5. Don’t let the inverter overheat

Always keep the capacity of the inverter in mind. Don’t overload it with high electrical devices and appliances. Doing so can damage the inverter or even make it explode. Also, when an appliance is not in use, unplug it to reduce the load on the inverter and increase the lifespan.

 

6. Keep the inverter away from flames or heat

Heat and flames can damage your home inverter. It can harm both the inverter and your battery. So always keep the inverter away from fire and heat.

 

7. Discharge the battery occasionally

Sometimes, if you don’t face any power outages for a while, you might forget about your inverter. As a result, your batteries always have a full charge. It’s not good for them if they stay like that for a long time. Even though there are no power cuts, try to use the inverter just to discharge the batteries. Doing so at least once a month is good for the batteries.

 

8. Keep out of children’s reach

Kids can be rather curious. With your home inverter, they might accidentally spill food and liquids over it. They might even start playing with leading to the inverter getting damaged. More importantly, the child has risks getting a full or partial shock. So, always keep it out of their reach. However, wherever you keep the inverter, make sure the area is well-ventilated.

 

9. Keep the terminals of the battery clean

Always keep the terminals of the battery free from rust and corrosion. You can do so by mixing a solution with baking soda and hot water. Using a small brush, carefully put the hot water and baking soda solution on the battery terminals. To avoid the corrosion and rust on other metal parts like bolts and nuts, keep them lubed with petroleum jelly. Having rust on the terminal can bother the flow of electricity to and from the battery.

 

Best Inverter for Home: Frequently Asked Questions

1. Can I keep the inverter in one of my rooms?

We advise you to keep the inverter in open places, such as near a window or a balcony. That is because it emits hydrogen fumes and other gases. To make sure you don’t inhale these gases, you should keep the inverter in somewhere with good airflow.

 

2. Can I power off the inverter?

Turning an inverter off discharges its battery completely. Thus, it won’t be able to provide you with backup when there’s no power. As such, you shouldn’t turn the inverter off. However, if you want to check it or refill it, then you can turn it off. If you do, then make sure to turn it back on once you’re done refilling.

 

3. Why does my inverter make continuous beeping noises?

A beeping inverter generally means that the battery levels are running low. So you should make sure to charge it as soon as you can. Although, it might also be happening because of a capacity overload. In such a case, you should try to remove the extra load by turning some appliances off.

 

4. Will I get batteries with the inverter?

Although inverters need batteries to work, you’ll still have to buy them separately. You can choose the battery size according to your requirements.

 

5. How is peak load and continuous load different?

Before you decide the size of the inverter, you should understand the difference between continuous and peak power output. It is a vital factor.

The continuous load is the wattage that the inverter runs on. Meanwhile, the peak load is the starting load that is needed to get the device running. The majority of the inverters have a peak wattage which is twice the continuous wattage.

If you have a refrigerator that starts up with a load of 15 amps, with a continuous load of 5 amps, then the peak surge would be:

5 Amps X 120 Volts = 600 Watts of Continuous Load

15 Amps X 120 Volts = 1800 Watts starting load

Therefore, you have to look for an inverter with a peak surge rating of more than 1800 Watts.

 

6. What is a Solar Inverter?

A solar inverter is an inverter that converts DDC output of a Photovoltaic Solar Panel into AC to provide electric backup.

 

7. How do I know if the inverter is fully charged?

Methods vary with most inverters, but there will always be a way to gauge the charge. Some will show you the charging status in the indicator display. Some have alarms to let you know when the batteries reach full charge. Most inverters come with overcharge protection so you wouldn’t have to worry about forgetting to stop the charge.

 

8. How do I install my inverter?

Although a lot of inverter brands offer a warranty, that doesn’t include installation services. To install your inverter, you can get the help of an electrician.

 

9. Is it normal for my inverter to make noises when operating?

Indeed, it is normal for your inverter to be making some form of noise as it works. The noise is a result of the inverter converting current from the battery.

 

10. Are there other uses of an Inverter?

Aside from providing backup in the events of a power cut, you could use your inverter in other ways. For instance, it’s useful for solar power generation, as it can convert the generated DC to AC for home use. Furthermore, it stores the excess power that gets generated. Certain types of UPS use a small inverter to increase their efficiency and quicker charging of the UPS battery.
