How do Solar Inverters Work?
Solar inverters are just like electric inverters but they run on solar power. The solar inverter takes up the solar power and transforms it into the AC power. This power, then, can be used for the functioning of domestic appliances.

Solar Inverters Types
There is more than one type of solar inverters. All of the types are discussed below:
1. String Solar Inverters:
These solar inverters are known to use a single string of solar panels. These panels are placed and connected in a series for the energy production. This type of inverter is used mostly in Australia, Asia, and Europe.
2. Hybrid Solar Inverters:
Hybrid solar inverters work with the combination of two mechanisms. It has a single unit of energy which is formed with the combination of a solar inverter and a battery inverter. These inverters are more affordable and advanced.
3. Off-Grid Solar Inverters:
It is also called a stand-alone inverter. By using a powerful battery inverter, you can easily set up an AC or DC coupled system with these inverters.
4. Micro Solar Inverters:
As the name says, these are micro inverters. These small-sized inverters are connected to solar panels directly and hence, they work independently. You can install these in places where the roofs are a little complex. These inverters are costly though.
Best Solar Inverter in India Buying Guide & Tips:
Factors to be Considered Before Buying the Best Solar Inverter
While buying a product, there are various factors that should be kept in mind. Below, we have collected some of the points that should be kept in mind before you go to buy solar inverters.
1. Output Type of Inverters:
The solar inverters are of various types. Based on the power output type, the solar inverters have three types. These types are explained below:
i. Sine Wave:
This is the most common type of output given by the majority of generators or utility companies. As it is common, it makes almost every electrical appliance compatible with the inverter.
ii. Modified Sine Wave:
It is just another type of sine wave but a little modified. This output type has a square pattern. Although this output type solar inverter is compatible with the majority of appliances, it uses more power. This simply limits the efficiency of the appliances used.
iii. Square Wave:
This output type makes the cheapest solar inverter. It is affordable by almost everyone but does not work well with heavy appliances. Due to this reason, it might not be a great product for longer use.
Now, you have gone through the various output types that solar inverters give. You can choose the one that works well for you.
2. Efficiency:
It is an important factor that should be kept in mind. Efficiency means the load that the product can take while functioning. Choose the inverter that provides a higher efficiency as 100% efficiency isn’t possible because of some heat generation.
3. Size of the Inverter:
The size of the solar inverter depends on the usage. Buy a solar inverter that works well with the place where you are installing it. If the area is big, a large size is better than the smaller size.
4. Inverter Power Rating:
Choose to buy a solar inverter that provides you with a better Ingress Protection rating (IP rating). As there are harsh conditions like water, high temperatures, fluctuating voltages, dust, etc. that an inverter has to go through, always choose the one that has a higher IP rating.
5. Protection Features Present in an Inverter:
A solar inverter, like any other electric appliance, goes through a constant threat of damage. Choose to buy a product that has some internal features to protect the inverter from getting damaged.
6. Battery:
You should buy an inverter that has a longer battery life. It is an important feature as the inverter will work on the power supply as long as the battery works. If an inverter has a longer battery life, your appliances can use up the battery for a longer time and in situations of long power cut, it is a better option.
7. Warranty:
You should always check the warranty offered by the company on their products. Choose the ones that provide a good warranty as it can be pretty costly to maintain the solar inverters if they get damaged.
8. Pocket-Friendly Product:
There are various types of solar inverters present in the market with ranging prices. Always buy a product that is pocket-friendly and does not make your budget go out of hand.
9. Monitoring of the Solar Inverter:
Every solar inverter needs some monitoring so that its performance can be easily tracked. The performance of the inverter can be tracked easily with the help of a monitoring system. Choose the product that offers a good solar system monitoring with high accuracy.
10. Problems and Functions of the Solar Inverter:
There are various problems faced by the solar inverters. Even though they are sturdy and can easily resist winds, rains, and more, there are still some measures that should be kept in mind. The inverters generate energy for longer times without being placed under shelter or dry place can have some fault in it. So, always keep the solar inverter in a place where it is not exposed to heavy rainfall or temperatures to keep it lasting longer.
In the end, you are recommended to buy a solar inverter that fulfils all your needs. Along with it, make sure that it is pocket-friendly. Do keep in mind the factors we have discussed above in the buyer guide so that you end up buying a good product.
Frequently Asked Questions (FAQs)
Q. Where should you install a solar inverter?
Ans: A solar inverter must be installed in a place where you can easily access it as you will need to maintain it. The place for the installation of the solar inverter should have an air circulation system and should be moisture resistant and away from the direct sunlight.
Q. How long does a solar inverter work?
Ans: A solar inverter, if taken care of and maintained properly, can work up to 20 years. In the lifespan of the solar inverter, the product quality matters a lot.
Q. Are the solar inverters always noisy?
Ans: The solar inverters make a humming noise when they are working. The solar inverters change the direct current into the alternating current. There are some that make noise but not every solar inverter makes noise.
Q. Do solar systems stop working at night?
Ans: The solar inverters work because of the solar panels. The solar panels absorb the sunlight so that the product with which they are connected works. As sunlight is not available at night, the solar inverters stop working at night and work in the morning.
Q. What is the capacity of a solar inverter?
Ans: The capacity of a solar inverter depends on the battery back-up. The higher the battery back-up, the better the capacity.
Q. Can water pumps work on solar inverters?
Ans: Absolutely! The solar inverters can work well with almost every electrical appliance. The water pump takes somewhere between 250-1100 Watts of power. So, as long as the solar inverter has the battery back-up enough for the water pump to work, it can work pretty well.
Q. Is it necessary to clean solar panels regularly?
Ans: A country like India is a place where dust accumulates quickly on everything. The solar panels are not dust resistant and hence, need proper cleaning at proper intervals. You must clean the solar panels every day or twice a week so that the power can be generated without any problem. You can clean the solar panels with a wipe after spraying water on them.
Q. What is the right angle for maximum energy output from the solar inverters?
Ans: The right angle for the installation of the solar panels depends on the latitude of the place where you are planning to install them. Generally, the tilt angle ranges from 9 – 12 degrees in southern India whereas in northern India, the tilt angle needs to be between 25 – 30 degrees. When you have to install the solar panels at a higher altitude, the tilt angle decreases so that the wind speed impact can be nullified.
Q. How many solar PV modules can be connected in a solar inverter string?
Ans: PV modules’ open circuit voltage (VOC) and maximum voltage that inverter can stand decide how many PV modules you can connect with the solar inverter in a string. If VOC is 44 V and the solar inverter can take up 1000 V, then maximum PV modules attached to the solar inverter will be 22 in a series connection.
Q. How can you maintain a solar inverter?
Ans: You can maintain the solar inverter by cleaning it at regular intervals with the water and wipe. As solar panels have a lifespan of almost 25 years, there is nothing to worry about. Although, proper maintenance is needed for proper functioning.
