Things to Consider While Buying an Inverter for home
There are many factors to consider when you decide to buy an inverter. You have to calculate the inverter capacity to ensure that it fulfills the requirements perfectly. Besides, you need to decide on the type of inverter-based on their advantages.
There are other parameters and specifications to check, which can be quite overwhelming for a buyer. Therefore, we are putting together a detailed buying guide for inverters, which contains all the information you need to know.
How To Find The Inverter Capacity You Need?
Step 1 – Calculate The Backup Power Requirement
First, you have to decide which appliances you want to run with inverter backup power. Once you do that, you can easily calculate the power consumption of those appliances. The following table contains the approximate power consumption by common appliances. To be more specific, you should check the specifications of the appliances you use.
|Fan (Ceiling)||50-75 Watts|
|Fan (Table)||25-50 Watts|
|CFL Bulb 20 Watts||20 Watts|
|LED Bulb 10 Watts||10 Watts|
|Computer (Desktop)||80- 150 Watts|
|Laptop||20- 75 Watts|
|LCD TV (32”)||150 Watts|
|Refrigerator||160 – 250 Watts|
|Tube Light (4 Feet)||40 Watts|
Suppose, you want the inverter to support 3 ceiling fans, 3 tube lights, 1 CFL, and 1 LED bulb. The total power requirement is (3 x 60 + 3 x 40 + 20 + 10) is 330 watts.
Step 2 – Calculate The Inverter Capacity Required
The capacity of the inverter is measured in VA or Volt-Amp. To calculate VA, you should use the following formula.
VA = Power Requirement / Power Factor or Efficiency
The power efficiency or power factor of an inverter varies from 0.6-0.8 in India. We have already calculated the power requirement, which is 330 watts.
The capacity/power of the inverter should be at least (330/0.7) = 470 VA.
Therefore, to sum it all up, you have to opt for an inverter with a power rating or capacity of 470 VA or more. This will support all the appliances comfortable when the power is off.
Types Of Inverter In India
There are two types of inverters available in India, and the difference lies in the output waveform.
- Square Wave
A square wave inverter is less expensive. It makes noise, and the power supply to the appliances is relatively less safe. Hence, it is suitable if you want backup power for fans and lights and other such basic appliances.
However, it is not recommended for sensitive and heavy power-drawing devices. It generates significant heat, and you should not place it in a very close and congested place. Furthermore, it reduces the lifespan of the battery in the long run.
- Pure Sine Wave
Even though it is expensive, it is the best inverter to buy. Such an inverter is highly efficient, and it expands the lifespan of the battery. Most importantly, it is suitable for all devices, and the noise level is negligible. Moreover, the heat generated is quite moderate, and if you have the budget, go for it.
Apart from these two types, there is one more type, even though it is not widely available. It is the modified sine wave inverter whose efficiency and other parameters fall in between a square wave and pure sine wave inverter. But the heat generation is the lowest in this type. It is for those who cannot afford a pure sine wave and looking for an alternative instead of buying a square wave.
Factors To Consider While Buying An Inverter
The inverter must be compatible with the power requirement of the appliances as well as with the capacity of the battery. To calculate the capacity of the battery, you need to take the following steps.
First, the capacity of a battery is measured in Ah or Amp-Hour. This means the amount of current the battery can supply for a specific time duration. A 100Ah battery capacity means it can supply 100amp of current for one hour. Alternately, it can supply 50amp of current for 2 hours and likewise.
Second, use the following formula to calculate the battery capacity you need.
We have illustrated at the beginning of the guide on how to calculate the power requirement (total loads in watts). The voltage refers to the voltage of the battery, which is generally 12V though there are 24V batteries also available for industrial purposes. Lastly, the backup in hours depends on your requirements. Here is an approximate estimation of the battery you need for certain power requirements.
|Power Requirement||Backup Time||Battery Capacity Required|
|600 Watts||2 hours||(600 * 2) / 12 = 100Ah|
|900 Watts||2 hours||(900 * 2) / 12 = 150Ah|
|1000 Watts||3 hours||(1000 * 3) / 12 = 250Ah|
While buying an inverter, make sure the inverter is compatible with the battery capacity for optimal performance.
2. Battery Type
The inverter also needs to be compatible with the battery type. There are three types of batteries for inverter available in India. They are flat plate battery, tubular battery, and the modern maintenance-free battery. Without going into detail, we are listing down the differences among these three types.
|Parameters||Flat Plate Battery||Tubular Battery||Maintenance-Free Battery|
|Battery Life||Low (~ 3 Yrs)||High (~ 5 Yrs)||Medium (3 to 4 Yrs)|
|Water toppings requirement||High||Medium||Low|
|Price(INR)||9,000 to 15,000||9,000 to25,000.||Above 10,000|
|Top Brands||Amaron, Exide, Luminous, Su-Kam||Amaron, Exide, Luminous, Su-Kam||Luminous|
It is better to buy the battery before buying the inverter and choose an inverter that is compatible with battery capacity and type.
The modern inverters are not merely converting DC to AC like traditional inverters. There are some inverters available that are also voltage stabilizers. They protect your devices against voltage fluctuation. Apart from that, some of the advanced inverters also act as UPS.
The difference between UPS and inverter is that the time delay to switch power during a power cut is negligible in UPS. On the other hand, a traditional inverter takes a few microseconds for switching. In these microseconds, a sensitive device like a computer can crash or get restarted. So, if you have sensitive appliances at home, opt for an inverter that can act as a UPS as well.
An inverter plays a major role in protecting your battery. The battery is expensive, and it needs protection to expand its lifespan. An inverter protects the battery from overloading when the load is coming from different appliances. It does so by resetting the load.
Apart from that, it prevents overcharging and even undercharging by shutting down the battery once the charge reaches rock bottom. Moreover, the latest inverters prevent discharging of the battery when there has been no power cut for days. Some of them come with inbuilt MCB to prevent short-circuiting. Watch out for these protections in the description of the inverter you are planning to buy.
An inverter should be user-friendly. This means it should have a proper display or indicators to understand the current status. The display can show the backup time the battery can produce as per the charge level. Some show the current load and beeps or blinks when there is overload. Some of the advanced inverters also show the water level of the battery so that you can refill when it is low.
The modern inverters come with the latest technologies and chips to optimize the charging process. This means when the battery is low on charge; the charging gets faster until it reaches a 50%-60% level. Similarly, when the charge level is medium, the charging process gets normal.
Apart from that, certain hybrid inverters can make the battery charge through the main supply electricity as well as through solar energy if you have solar panels installed.
If you have such setup or you are planning to set up a solar panel, opt for such a hybrid solar inverter, and you get to save a lot in your electricity bill in the long run.
Under normal circumstances, an inverter can last for over a decade. However, an inverter must come with a warranty period. The higher the warranty period, the better the product is. Do not buy an inverter that does not come with a warranty. Most of the popular inverter brands offer a warranty period from 2 to 5 years.
7. Bypass Switch
There are going to be times where the inverter may start malfunctioning due to age or lack of proper maintenance. Due to this, some of the inverters come with a bypass switch so that the electricity can flow to the connected appliances directly without involving the inverter. Therefore, you do not have to suffer any power blackout due to inverter malfunction.
Some Frequently Asked Questions
1. What is an inverter?
An inverter is a system that converts DC to AC. As we all know that we get 230V of AC for home from the main transformer. When an inverter is placed in your home, it grabs the unwanted DC components in the signal and then converts to AC which is helpful for the smooth functioning of the home appliances.
2. How does solar inverter work?
Solar inverter functionality is similar to the regular inverter. But what makes the solar inverter more special is the use of solar power that can be trapped using Photovoltaic solar panels to feed the energy into the electric home appliances efficiently. It even saves your electricity bills than regular inverter models.
3. Do inverters make noise?
Inverters do make noise while performing certain operations. The noise is actually generated from the exhaust cooling fan present inside the inverter that runs automatically when the heat is generated. Thereby producing the noise in inverters.
4. Can we connect inverter batteries in series or parallel?
Inverter batteries can be connected in series or parallel just for increasing the power supply to the electrical or electronic devices. But the input power will be same all the time.
Batteries connected in series have more advantages than in parallel Because, when you connect the batteries in parallel, the internal resistance of each battery differs and draws more power which results in huge loss. In case of series connection, there are minimal losses of power.
5. Where should I place the inverter at home?
You can simply install the inverter anywhere you want. But, be sure that there is at least half feet distance on all sides. And some inverters should not be placed in direct sunlight because it may lose efficiency and won’t work properly.
6. Is it possible to run ACs using inverters?
Without any doubt, you can simply run ACs on inverters. As inverter alters the current (DC to AC), you can make the device AC work for a short period of time because of the battery lifespan. And again you need to recharge the battery for prolong usage.
But, these days, ACs have come with inverting technology to offer you the best performance without any power failure issues. To know how these inverter ACs play a crucial role in providing chillness in a room, Read Best Inverter Air Conditioners in India 2020.
