Inverters for Home Buying Guide

Before you buy the best inverter in India, you must know some key factors to equip yourself with required knowledge that will help you in choosing the best inverter for your home. You should know what features would give you the best outcome and suitable for your home. Inverters are long time investment, therefore read the below buying guide.

What is an Inverter and How it Works?

As a backup power device, an inverter works to turn low-voltage direct current power (DC) to regular alternating current (AC) power. With its help, you can operate different appliances in your household. In times of power shortages or blackouts, this is necessary to work as a backup generator.

A lot of different appliances use this power run normally, depending on the battery and its capacity. Many of the electrical devices work through an inverter by cultivating power from other resources. These include boat, truck, car battery, or renewable energy sources like wind turbines or solar energy.

Types of Inverters

There are 3 types of inveters:

1. Sine Wave Inverter

In this type of inverter, there is AC machinery that keeps rotating to produce power. The capacity of this inverter is high, and thus, most high-efficient products work with it. It can hold and provide a lot of loads, and maximum electric devices gel with it well. Thus, it is the most expensive among the inverter types, too.

Device examples include:

• Laptops
• Mixer grinders
• TV
• Household appliances like a fridge

2. Square Wave Inverter

Out of all the best inverter India options, the square wave version is the most low-priced. As such, they are not too powerful either; they operate fine but not with most appliances. Only those that require minimal power to work can perform with this inverter.

Device examples include:

• Fans
• Lights

3. Modified Sine Wave Inverter

In this particular type of inverter, the shape of the waveform is in a square style. Sure, it works well with most devices and is comparatively cheaper than its namesake. Yet, it has the potential to reduce a device’s efficiency.

Plus, the fluorescent lighting in this is less bright, and it emits a buzzing or humming sound frequently. Nevertheless, it does its main job well enough.

Device examples include:

• Computer
• TV (older models)
• Motors
• Lights

Types of Batteries

Batteries are supplementary of inverters. Without them, even the best inverters are useless. Power backup and inverter duration is directly dependent on battery and therefore it is important to discuss them here briefly.

1. Tubular Battery

These batteries last lost, averaging at five years. They do not require a lot of maintenance, and their charging cycles are very efficient. In this, the battery tubes stay within a piece of cloth. As for its price in India, the range varies from Rs. 8,000 to Rs. 25,000.

2. Flat Plate Battery

A flat plate battery is one of the original lead-acid batteries. Two electrodes in this stay inside the liquid electrolytic water and sulfuric acid solution. The positive one is made with lead oxide and the negative with porous lead. People need to constantly maintain it, changing the water at each 3-6 months interval. If not done so, it would stop working with time. You also need to place them in a ventilated area since these batteries give out noxious gases. As for the cost, it’s cheaper than tubular batteries, ranging within Rs. 9,000-15,000 bracket.

3. Sealed Maintenance-Free Battery

They do not need maintenance and are comparatively safer than the other two. It does not give out any obnoxious gases, and you do not need to refill with distilled water constantly. They are comparatively more costly than the other two but have a smaller lifeline. Another common name of this battery is Value Regulated Lead-Acid or VRLA battery.

Features to Look For Before Buying an Inverter

There are some particular features that an inverter would have that makes them a better choice. When you are choosing an inverter for your home, these are some specifications you should assess:

1. Capacity

The first thing you should think about when you are buying an inverter is their capacity. You would notice this as the VA rating (Volt Ampere). This refers to the power that the inverter gives to the different devices attached to it. If it is working perfectly as per the power requirement of the equipment, then in the ideal world, this rating would appear 100%. However, that is not always possible, and the regular efficiency range of inverters value between 60% to 80%.

The equation here is as such:

Inverter VA rating (power supplied) = the power the electric items consume (power requirement) / efficiency of an inverter (power factor)

For example, if the power requirement of your television is 120W and the average power factor values at 0.7.

Therefore, Average VA = 120/0.7 = 171.42 VA.

In general, an inverter with 800 VA power is a good enough choice for small to medium houses. But if it’s a big house and you need the power supply for more electrical appliances, then you can select 1200 VA models.

2. Power Requirement

When you buy an inverter, you need to think about how many appliances you need the backup for. Depending on that, you should decide on your inverter to hold as many items as possible and not lag.

The general power requirements for some appliances are mentioned in this table hereafter.

Type of Item	Power Requirements (Watts)
Fan	80
CFL	20
Light (Tube)	40
Light (LED Bulb)	5-100
Washing Machine	150-3000
Television	100-300
Window Air Conditioner	1000-2500
Induction Cooktop	1500-3000
Refrigerator	140-450
Microwave Oven	2500

In this regard, count how many items you have at your home. For example, let’s say you have 2 tube lights (40 watts each), 4 fans (80 watts each), 2 CFL bulbs (20 watts each), 3 LED bulbs (10 watts each), 1 refrigerator (300 watts), and 1 television (200 watts).

The total power you would need is:

(2*40) + (4*80) + (2*20) + (3*10) + (1*300) + (1*200)= 970 W.

Thus, you would need an inverter with more than 970 Watts power capacity or 1200VA.

3. Output/Input Voltage

You should select an inverter with the same voltage power as the battery you are using inside it. This counts for both Output Voltage (AC) and Input Voltage (DC) inverters.

Here is an example of the latter.

In case you have a battery of 12V power, you should select an inverter with 12V DC power.

Also, consider the country you are in, as far as the Output Voltage is concerned. In India and most other countries, you can use an inverter with 220-250V AC potential. Only Mexico, Canada, the US, and most Latin America parts need ones with 120V AC potential.

4. Charging Power

See how much the inverters can charge and what type they are. Bigger inverters can provide power for a longer duration, and you need to add extra batteries to extend the backup duration. As for smaller inverters inside vehicles, it runs equipment as long as the battery works and the engine runs.

5. Battery

Not only is the inverter itself important to consider, but so is the battery you use in it. It is the main power structure behind this, and you need to consider the battery quality over anything. It would affect the number of hours and items the inverter can run. The abbreviation for this is Ampere Hours or Ah.

You can find batteries of 100-220Ah capacity in the market easily. But you need to focus on the estimate calculation more rather than thinking about what is available.

Now considering the above example, your power consumption is 970 watts and you need a battery that can run for 4 hours. So, assuming the battery is 12 Volt, below is the formula to calculate the required Ampere hours.

Battery capacity (Ah) = Power Requirement (W) * number of backup time (hours) / voltage of the battery (V)

Therefore, as per the example provided previously,

Battery capacity = (970 * 4) / 12 = 323 Ah

Thus, you need a battery with a capacity of 323 Ah power or more. Before you end up purchasing an inverter in India, you should consider this carefully.

Additional Points to Consider

Aside from the features mentioned, there are some points that you should consider, too, before placing your order. They are related to your circumstances more than the quality of the inverters.

1. Price

You have to look at the inverter price to decide on what you need as well. And for the most part, the range of this lies between Rs. 5,000 to Rs 8,000. It depends upon many factors like the technical specifications, the brand, and its traits.

The quality of a good inverter depends on how less energy it loses during DC to AC energy conversion. While you would find many options, the best ones with the least energy loss are of the costlier variety. The higher the price, the more they can manage bigger appliances. Thus, consider this when you are buying the inverter of your choice.

2. Earthing issues

First and foremost, see if your home has good quality earthing potential. Many electricity-related accidents can occur without warning, like electrocution or short-circuits. If a house has good earthing facilities, the effects are not felt as badly.

Plus, on your part, you should ensure that the dogs or children at home do not get near the inverter. And make sure not to touch any of the battery terminals if your hands are wet, either.

3. Wiring Concerns

Before considering the top inverter of your choice, you should see the wiring conditions at your home. You can take the help of an electrician beforehand for this. And they would detect if the backup facility of the chosen inverter is compatible with the wiring.

You will not have much of a difficulty if you want to provide good power backup to most of your appliances. But you need to pay extra attention to the heavier appliances like a fridge or the ACS. In such a case, an electrician can isolate these in the wiring’s backups, and you should focus on them.

4. Bypass Switch

No matter what a great inverter you choose, there comes the likelihood that some difficulties would come up. For example, the device may face a power overload problem, or the fuse may blow. To safeguard the inverter from these eventualities, you can use a bypass switch protection.

You can bypass the regular inverter functionality when needed. The power would then go through the main electric grid instead of its original pathway. Thus, in case of emergencies, you can fix the inverter’s problem without disturbing the regular power supply in your house.

Important Safety Tips for Inverters

Of course, when you are using a power inverter, you should consider the safety measures too. It deals with electricity, and any wrong move can cause you and your family much harm. The following are some precautions that are worth considering.

• Make sure that you keep it somewhere that is not directly hit with sunlight. Windows are a strict no.
• You should avoid touching an inverter if your hands are wet. These devices are very good conductors of electricity, and many of the inverters do not have a shockproof surface. One may get an electric shock if they do so.
• Make sure that your younger children cannot reach it. Thus, keep the inverter at a higher flat surface, either horizontally or vertically.
• You should put it somewhere dry and cool.
• Keep this away from any appliance that releases hot air or a heat vent. Ensure the temperature of the surroundings is around 50 to 80 degrees Celsius.
• Avoid placing it near any flammable material.
• You need to keep checking the level of water in the battery occasionally. The tubular and flat batteries need clean, distilled water to function well. The period of replenishment varies between 1 month to 3 months. It depends mainly on how much you use the inverter as well as the battery type. Keep a note of the time and refill it at the right moments.
• When you are cleaning your inverter, you should use a microfiber cloth to do so.

Alternate Power Supplies

Aside from using the inverter, there are some other energy sources you can consider, too, for backup. They are as follows.

1. Solar Power

It is one of the most popular power energy sources currently. It takes the energy of the solar rays and converts them into electricity, which the batteries store. Given the source, this is one of the most energy-efficient power sources.

The places where solar energy is more, i.e., the sun rays are more intense, can use this power solution. It is good for smaller appliances only, though, and most cannot work with higher load appliances.

2. DG(Diesel Generator) Sets

Diesel is the main fuel that gives diesel generators (DG sets) the power to produce electricity. They generate the power instantly but do not store it. This is also suitable for appliances that take up bigger loads like air conditioners, desert cooler, and water pumps.

Inverter Vs. UPS

Both UPS and Inverters are good power backup solutions that can run many electrical items. There are certain similarities between the two, but there are specific distinctions as well. They are as follows.

Feature	Inverter	UPS (Uninterruptible Power Supply)
Back-up	The speed of the back-up is not too high. Due to some issues, one can face problems like data loss or system breakdown.	The speed is very fast. And that does not cost any data loss or crash in the system.
Fundamental operation	The inverter transfers electricity to the devices in one step. It changes DC power to AC power, which passes on to the devices.	The UPS's first step is to convert the AC power to DC power and then back to AC power in the inverter portion. Thus, in turn, passes on to the load.
Connection	It connects to the primary power supply to provide electricity to appliances.	It directly connects to the appliances and provides electricity.
Time Lag	After a power cut, the inverter lags for approximately 500 milliseconds before operating.	After a power cut, the UPS lags for approximately 3-8 milliseconds before operating.
Price	Inverters are comparatively cheaper.	The circuit or the machinery in UPS cause the hike in price.
Voltage	The voltage of input and output is around 230V.	The AVR (Automatic Voltage Regulation) is set at 220V.
Circuit	It holds two main portions: controller and inverter.	It holds three main portions: inverter, rectifier/charger, and controller.
Size	The size of an inverter is around 16 kVA.	The size of a UPS is around two kVA.
Usage	It is more suitable for areas that do not take up a huge amount of load. This is fitting for offices or houses.	It can provide a good amount of electricity to different sectors using its double conversion system. These include commercial spaces, houses, industrial uses, and offices.
Companies	Luminous, Exide, and Microtek provide some of the best inverters.	HP and APC provide some of the best UPS in India.

Maintenance Tips for Inverters

The above reviews of the best inverter available in India is perfect, but to make them long lasting, you can take some specific steps. There are some components where the inverters suffer the most damage, and you have to maintain them regularly. To ensure that the battery lasts for a long time, you should focus on the following points.

• The main thing that you should concern yourself with regarding the battery’s maintenance is the water level within. You should keep a reminder to refill the distilled water on time. The duration for this depends on what kind of battery you are using and how many times you used the inverter. Usually, the duration between each necessary replenishment period varies from one to three months.
• Try to avoid connecting the inverter and big-load items as much as possible. When you use it up, you have to recharge these big machines again, and doing so constantly would overuse the best inverters’ efficiency. Thus, you should use this to charge energy-efficient appliances mainly. This would make sure that the battery condition would not expire.
• You should apply grease at the connections of the sockets to safeguard it from rust decays or corrosion. If you see corrosion present regardless, you should clean these areas properly. Use a solution of baking soda and hot water and an old brush for that.
• The discharge from the battery occurs every month, and then it can start charging anew. You should encourage this as it freshens the inner electrolyte up.

Inverters Frequently Asked Questions (FAQs)

1. What is a solar inverter?

Unlike regular inverters, you can use the solar inverter in India to convert DC output into AC input voltage. The main element it converts from is the DC output that the PV solar panel emits.

2. How long can I use the inverter?

You can use the inverter for as long as you want to, but the inverter’s power depends upon the capacity of the battery. The more appliances you add, the higher the power discharge from the batteries. Thereby, the inverter run-time would also start reducing.
If you own a bigger inverter, you can add as many batteries as you want to gain run-time.

3. Which inverter brands are good for home use in India?

The best brands of inverters in India include Exide, Luminous, Sukam, and Microtek, to name a few.

• The reason behind Exide being one is that it produces high-power inverters that can last longer, and their batteries are durable.
• Luminous adds a lot of intelligent features to the inverters they produce.
• Sukam produces good hybrid-type solar inverters.
• Microtek delivers good quality inverters as well as UPS.

4. Would my electricity bill increase if I use an inverter?

When you charge your inverter, the amount of electricity it takes would appear on the bill as a cost. However, it takes less power than regular electricity, and thus, the cost is of a manageable amount. The bill is more when using inverters only if the batteries are aging.

5. How to stop the operation of an inverter?

You do not need to worry about switching off the inverter as it does this task automatically. Many of the inverters have an automatic power feature. When the house’s power goes off, the inverter starts up and resumes the power backup to appliances. Similarly, when the power comes back again, the inverter would automatically switch off.
As for manual control, you can switch the device off when the battery charging is done. In such a case, do remember the batteries would still emit the saved energy even if the inverter is off.

6. What rate does the battery drain at?

The speed of the battery drains based on the design and unit of the battery system. The rate differs between 0.02 amps and two amps. Plus, if you have your inverter switched on but no appliance attached, the battery continues draining. The general rate of reduction per week is 168 amp, per day is 24 amps, and per hour is 1 amp.

7. Why my inverter is making noise?

The meaning behind the sound you hear from the inverter depends on the type of sound you can catch.

• One type of sound indicates that the current conversion is occurring inside the battery at the moment.
• Another possible reason for a sound is that the inverter capacity is overloaded. In such a situation, you need to switch off some appliances to reduce the load.
• If a beeping sound is audible continuously, that means that the battery is down and the inverter needs recharging. It signifies a very low level, and you must replenish the product quickly.

8. What causes an inverter to fail?

When the electro-mechanical functions of the capacitors wear down, that can fail an inverter. These particles are very sensitive to heat. When there is a high current, the temperature goes over the operating temperature that is specified. This heating can reduce the performance of the capacitors.
Also, the inductive component cores generate ultrasonic vibrations. These vibrations create the friction that also heats the battery. This, along with the product’s heating, is too much for its inner parts to handle. And that would damage the inverter overall.
