An inverter is a device that converts DC (direct current) in to AC (alternating current) which is widely used in homes and for commercial purposes. A solar inverter also works in a similar way only the source of the DC current is different in this case.
A solar inverter is a part of a solar energy setup that consists of photovoltaic solar panels, charge controller and batteries. The photovoltaic solar panel produces variable DC current and the solar inverter converts it into AC current.
Central inverter is the most common type of solar inverter used in homes. Although, a solar energy system requires an elaborate setup, it helps to save money in the long run because the energy used from the sun to produce electricity does not cost anything. In addition, solar energy system can be used to get electricity even in remote locations because it does not require connection to power or gas.
But, when it comes to choosing a solar inverter for your home, it is important to consider a few basic factors such as the type of inverter, its efficiency, its power rating, protection features of the inverter, etc. Click Here to how to choose the solar inverter based on your requirement.

Best Solar Inverters in India
First on our list is the Luminous Solar Hybrid inverter 1100 with 12 volts input. Luminous inverters are known for being intelligent and save power too.
The device does not come included with a battery. As for that, you would be using any Tubular battery with at least 2 different 150 ah capacity. You can also connect 2*200 ah batteries in parallel.
Given the solar and hybrid nature of the system, it can house and use any type of battery depending on how you charge it. But even if you regularly do not use solar panels for charging it, it is adviced that you always go for a solar tubular battery than a regular one.
As mentioned previously, this inverter has the potential of 850 VA power output in both AC and DC. But when it comes to the 12 volts DC output, there have been complaints about the absence of this socket. The device is sturdy, durable and can last for very long.
There is a low battery indicator given at the bottom of the dashboard. Given the price of the product, the integrated solar charging option is a good plus point. Most importantly, Luminous provides you with a massive 2 years of manufacturer’s warranty.
- Economically priced and quality product
- Hybrid (can use it for solar and normal charging too)

Next on our list is the Microtek Digital Solar UPS. Similar Luminous, Microtek is also solar and Grid-based solar inverter.
As is the case, it can provide 1135 VA power capacity in AC and DC power output along with a 12V of DC output. As for the battery, you can use any tubular or lead-acid battery as low as even 35ah too. But this gives you a very low back up whereas massive 220 ah batteries might take forever to charge to full. Ideal case scenario, go for batteries of order 150 ah. Even cascade them in paralell for faster charge and independent discharge.
It even has a 7 segment display that reads out on the status of the system when it is turned on. For the dashboard, you have the usual power on, power usage sign (if the device is using power from the grid or solar panels), overload and low power indicators.
This sinewave solar power system comes with save power technology, through which the Microtech stabilizer claims to provide very high performance. Also in cases of low or high cut off situations, it automatically cuts down the grid supply.
Though the product claims to be long-lasting and durable, it needs to work heavily on its reliability. There have been complaints about noise when the battery is getting recharged, the build quality and also the overloading issue of the battery. But as the product comes with a 2 years manufacturer’s warranty, there is not a lot of worries here.

There is an inbuilt LCD screen which is very convenient compared to the conventional segment displays or simple LEDs of conventional solar systems. The menu buttons of the dashboard let you customize a total of 20 different settings and combinations. These include charging priority, voltage range, battery charging current and load priority. Understanding how to work with each of these settings help you save not just energy and money but also helps you use it wisely during emergencies.
Easily mountable on a wall, the body of the product is very slim. It has a 3kVA power rating and an impressive 24V DC out power with a maximum efficiency of 93%.
The issue for this inverter begins with its pricing and ends with its performance. Given the pricing, one would expect a crystal clear and smooth performance. First off, the company does not provide any kind of battery, solar panel or any extra equipment. While no solar system comes with such a package, this pricing comes with expectations.
Under ideal conditions, the performance of the device is good for efficiency but when it is charging or discharging, the noise of the fan is loud.
And as for the surge protection, though the company mentions that the product can handle it, it is advised that you buy an additional surge protector. While the warranty is for 2 years, only after the proper installation of the surge protectors, you will be able to claim the warranty.
- Versatile and aesthetically good looking
- High energy rating (3kVA)
- 93% efficiency
- LCD screen instead of a segment display
- The internal fan makes sounds while operating
- Warranty, though at 2 years, needs you to submit installation details
Yet another Flin inverter, the Flin Energy is a very slim MPPT inverter with a massive 5kVA power rating.
This 5kVA rating can give you an equally massive 5000 watts of power output along with 48V of DC output. For storage, with the appropriate battery setup, you can easily leverage the 4kW solar storage capacity.
Though the power output rating is 5000 watts, expect usage of 2600 Watts (approx maximum usage for a big household). For a power back up of 3 hours, place in 6 batteries of 135 ah of Tubular batteries.
The MPPT (Maximum Power Point Tracking) solar charge controller facilitates the maximum capture and storage of solar energy. Also, the double surge power capacity with a high 93% peak efficiency makes this a reliable device for heavy electronics.

Yet another Luminous inverter, this time, it is a package deal. The luminous NXG1100 solar inverter package comes with a tall tubular battery and 2 solar panels of 160 watts each.
Speaking of the inverter, it is an 850va sine wave hybrid solar inverter with a 12V DC output, the same product that we listed in the first.
As for the battery, the LPTT12150H is a C10 tall tubular solar battery of 150Ah capacity. Made specifically for this pack combo, this battery comes with a massive 60 months( 5 years) of warranty.
Coming to the 2 solar panels, they are 160 watts Poly Crystalline panels. They come with a massive warranty of 25 years.
The solar system, when set up, takes in power from the Solar panels and from the Grid mains too thus ideally saving about 1.5 to 3 units of power each day.
While the package deal is sweet and actually a good one, the real challenge does not lie in the package pricing but the installation. Luminous charges a one-time installation charge of 5000 rupees on the package installation.
Apart from that, you also have the operating noise issue with the NXG100 as we mentioned at the beginning.
- Package deal with an inverter, battery and solar panels that are good for small households

Yet another variant of solar inverters from Luminous, the NXG1400 is a 1100vA capacity inverter with a 12V DC output.
NXG1400 comes with ISOT technology. The Intelligent Solar Optimization Technique or the ISOT by Luminous includes fast charge through its i-charge technology and also its dual modes.
Firstly, i-charge technology enables faster dispersion of charge. This means that in order to battle predicted longer power cuts, you can charge up your batteries faster during the grid power availability.
As for the dual modes, the NXG solar UPS has an ECO and a UPS mode. The Eco mode is for running normal and low energy appliances such as lights or fans. Here, the energy expenditure is low. The UPS mode is ideal when you use this for non-interruptive devices such as computers.
For batteries, you can use two 150ah batteries in series for the inverter. The NXG inverter has AC and DC outputs to its back. But there is no GCD (Grid Charge Disable) option for the inverter. This means that though it is intelligent enough to switch between GRID and Solar, you cannot voluntarily change it.
Also, there is the issue of power consumption. While this can be solved with selecting smaller batteries, it is still adviced for users to practice caution. As is the case with almost all Luminous inverters, this one too comes with 2 years of manufacturer’s warranty
- ISOT by Luminous which makes the inverter smart enough to switch between GRID and Solar power

How to Choose a Solar Inverter?
When you wish to have solar inverters in your home, you need to consider the several factors like the types, efficiency, battery life, power rating, and finally the price. Go ahead and read how these factors greatly helps you to decide the right one and also helps in improving the performance of the inverter.
There are 3 main types of solar inverters depending on the output they produce.
- Sine Wave – This is what you receive from your local utility company or from a generator. The best thing about this type of inverter is that it is compatible with almost all appliances and equipments available in the market. Most appliances require sine wave to work to their fullest efficiency.
- Modified Sine Wave – This is almost like sine wave but it has a square pattern. It is compatible with almost all equipments, but the equipments will have low efficiency in case of modified cine wave and as a result they will use more power.
- Square Wave – This is the cheapest type of inverter available in the market but it is seldom used because it is not compatible with most appliances and equipments. It may however be used to run simple tools with universal motors.
Efficiency of an inverter is the ratio of output power to input power. The efficiency of a solar inverter depends on its load. It is never possible to achieve 100% efficiency because some of the power is lost due to heat generated.
An inverter must be able to meet two power requirements – peak power/surge power and typical power. Surge power is the maximum amount of power that an inverter can supply for a short period of time. This surge is required for staring up appliances with electric motors such as pumps and refrigerators. Typical power is the power that an inverter can supply on a steady rate. Typical power is much less than surge power. An inverter with power rating of 50 watts is good enough for home use.
4. Power Rating
Solar inverters come in different power ratings ranging from 50 watts to 50000 watts but a household seldom needs more than 11000 watts power. Almost all standard solar inverters come in 50 to 5000 watts range.
5. Internal Protection Features
It is best to choose a solar inverter that comes with good safety features that protects the components against overload, lightning surges, etc.
6. Battery life
Battery life of an inverter explains how long the device can run using the power supply. In other words, it can be illustrated as the number of cycles it runs or charges the inverter till its end. It is usually expressed in milli-ampere per hour (mah).
My personal advice is to have inverters with the long battery life as it saves lot of power due to the usage of high-end material like lithium-ion, nickel- hydride etc.
7. Manufacturer’s warranty
Manufacturer’s warranty is the another important thing that you should look into before buying a solar inverter. If the product you wish to have or like is from a reputed brand and offers very good warranty services (say.. years), then you can opt for it without any delay.
Beware of brands that offer poor quality products and no warranty services.
8. Affordable price
Last one you need to consider apart from the above-mentioned factors is the price. Your budget on inverters will let you decide your choice and requirements. If you have enough money, then grab the high-end model inverters that have very long battery life and come with advanced options. Otherwise, you can go with the simple models that matches with your needs and also available at very low-prices.
Frequently Asked Questions
1.What is the lifespan of a solar inverter?
Solar inverter has maximum life of 25-years. But most of the branded models tend to have the lifetime of 10-years. Actually the lifespan of the solar inverter completely depends on the factors like maintenance, quality of the material and the battery usage. Malfunctioning of the device (internal circuitry) may also diminishes the life-expectancy of an inverter.
2. How a solar inverter works?
Solar inverter uses an inverting technology to convert the direct current (DC) into the alternating current (AC) that can be fed to the electrical circuits later. It produces different signals like sine or square wave to make the electronic devices run efficiently for a specific purpose and can be adjusted with proper protection.
3. Can you differentiate AC and DC currents?
Alternating current (AC) explains the periodic flow of charges in only one direction. It can also be expressed as the change in the direction of electric current n-times at regular intervals of time. With the help of AC, you can power up the motors and generators of the same device and many other applications like refrigerators, dishwashers etc. that completely runs on AC.
Whereas in Direct current (DC) the flow of charge is unidirectional and offers the constant voltage or current. This mechanism is mostly seen in low-voltage appliances like fuel cells, telecommunication and automotive industry.
4. What should be the size of an inverter you choose?
As we all know that inverter is rated in watts and hence all the inverter appliances have a wattage rating. It may not be same for all electronic appliances and can be calculated as:
Wattage= Power (in watts) = Voltage(volts)*Current(amperes)
Given below table explains the different electronic devices and their wattage readings. Check it out!
|Electronic Appliances||Wattage Rating|
5. How to select the right inverter for home appliances?
If you are planning to have inverter in your home, then you need to select the right inverter as the power required for your home is completely different. So you can’t blindly select the inverters as you need to consider the several factors like battery life, power utilization, efficiency, power backup options, and protection. There are different types of inverters available in the market and you need to select them as per your requirement like for supplying power to ACs, refrigerators, bulbs and outdoor gardening lights, pathway strip lights etc.
6. Do solar inverters produce noise?
Yes, solar inverters do make a lot of noise (expressed in decibels-dB). It’s very horrible to hear it as you may doubt malfunctioning of the device. But it’s actually not. It generally produces lot of noise when used to power high-end products like ACs, refrigerators (25dB).
7. Do solar inverters emit radiations?
No, solar inverters do not produce harmful radiations. As the inverters associated with electrical or electronic device, creates electromagnetic field which does not create any negative effects while using. Hence solar inverters are good to use and can handled safely by the children.
