Best Of-Grid Solar Inverters: Things You Must Know Before Buying
There are certain things one must know before buying the best on grid solar inverter in India. These are factors that will provide you with some basic knowledge of what you need to have before buying such a device.
1. Types of Solar Inverters
It’s a must to be aware of all the types of solar inverters before buying an off-grid one. After all, you need to be sure that an off-grid is what you really need. The types are-
- Off-grid solar inverters: These are also known as standalone solar inverters. With the help of powerful battery inverters, they can set up DC or AC-coupled systems. The off-grid technology can be utilized to produce hybrid grid-connected inverter systems.
- On-grid inverters: They are also known as grid-tied inverters. Their job is to convert DC power generated by solar panels into AC power that is used by the electrical grid.
- Hybrid Inverter: This type of inverter combines the earlier two mechanisms to formulate one inverter. It combines a solar inverter and a battery inverter. This type of inverter is quite appealing, advanced, and affordable.
- String Solar Inverters: These inverters use a string of solar panels that are placed one after the other and connected to produce energy. It is typically used in Australia, Asia, and Europe. Slowly, it is also gaining popularity in the USA.
- Micro solar inverters: These are small solar inverters directly attached to single solar panels. They work independently and are thus a great option for roofs that have shade issues or slightly complex structures. These types of inverters are not popular in India due to their high price.

2. Output Type
The solar inverters are further divided on the kind of output they have. Here we’ll at the three types of output solar inverters have-
- Square Wave: These are present in the cheapest solar inverters in the market. Although these types of inverters are affordable they do not support heavy appliances. Hence, from a long-term perspective, these inverters aren’t a good investment.
- Sine Wave: This type of output is usually present in any generator or your local utility company. The inverters with this output type are compatible with almost all electrical appliances, in the office or house.
- Modified Sine Wave: This is yet another version of the sine wave; the only difference between them is in the square pattern. Although inverters with this output type are compatible with many appliances, they do need more power and thus limit the efficiency of the appliances.
3. Efficiency
This is another important criterion you need to consider before buying from the top 10 solar on-grid inverters in India. The ratio of output power and input power tells you the efficiency of the solar inverter. To a large extent, its efficiency is determined by the load on it. Since some power is always lost in the form of heat, 100% efficiency in solar inverters can’t be achieved.

4. Size
A solar inverter needs to meet two power requirements- one is typical power and the other is peak power. Typical power is the power that is supplied at a steady and standard rate. Typically, this is far lesser than the peak power.
On the other hand, peak or surge power is the maximum amount of power that the inverter is able to supply within a fixed period of time. Heavy appliances like refrigerators and pumps require this surging power to start their motor. A solar inverter with 50 watts power supply is good for purchase. However, an on-grid solar inverter with 50 watts will only be able to run small appliances and won’t be apt for commercial or residential solar power systems.
5. Power Rating
Solar inverters are used for various purposes, at home, offices, and in other larger institutional spaces. To suit varying purposes, they are available with a power rating that ranges from 50-50000 watts. For homes, solar inverters with power ratings less than 11000 watts will also do. Typically, standard solar inverters have a power rating of 50-5000 watts.
6. Internal Protection Features
Any electrical appliance is always under the threat of damage or another. This is especially in the case of heavy appliances. You need to purchase a solar inverter to protect the various components of your solar system from getting damaged due to overload, lightning surges, and so on.

7. Battery life
It is crucial to check the battery life of the solar inverter you are planning to buy. The battery life decides how long your solar inverter will function using the power supply. The number of charges or cycles that the inverter requires displays the battery life of the solar inverter. This is expressed by milli-ampere per hour, or mah.
Most experts suggest that you should go for a solar inverter with longer battery life. Since these batteries use elements like lithium-ion, nickel-hydride, and so on, they tend to consume less power. That is why these batteries are preferred.
8. Manufacturer’s Warranty
It’s a must to check the manufacturer’s warranty before buying a solar inverter. A good solar inverter company will provide you with a comprehensive warranty that lasts many years. Always compare the warranty period of different brands before making any purchase. Go for reputed brands that offer years of warranty.

9. Budget
It is a major aspect of what kind of solar inverter you buy. An individual with a big budget can always buy high-end inverter models that have longer battery life and various advanced features. However, even with a tight budget, one can find inverters that meet their needs.
10. Solar System Monitoring
Every solar inverter provides some sort of remote monitoring, which helps track the performance of your device. It helps you track its performance and operations. Before buying any inverter model, check for the remote monitoring features it has. Now, you know the process of selecting the best on grid solar inverter in India.
What are the Features of an On-Grid Inverter?
The features of an on-grid solar inverter are-
- Efficiency: The on-grid inverters offer great efficiency and compatibility with heavy loads.
- Easy Installation: The installation of these inverters takes less time. Typically, it takes an hour to install a string inverter.
