Best Solar inverters: Things you must know before buying!
There are a couple of crucial factors that you must take into consideration before buying the best solar inverter in India. These factors will provide you with some basic knowledge that you need to have before buying this appliance. After all, it is a long-term investment and you would want to get it right.
1) Types of solar inverters
- String solar inverters- The string solar inverter uses a string of solar panels that are placed one after the other and connected to produce energy. This type of inverter is commonly used in Asia, Europe, and Australia, and is slowly gaining popularity in the US as well.
- Hybrid inverters- As the name suggests, this type of inverter combines two mechanisms to formulate one inverter. It builds one simple unit of energy by combining a battery inverter and a solar inverter. Hybrid inverters have turned out to be more advanced, affordable, and overall appealing and hence, these are surpassing the popularity of regular solar inverters.
- Off-grid solar inverters- Off-grid solar inverters are also known as stand-alone inverters that can set up AC or DC coupled systems, with the help of powerful battery inverters that come with in-built chargers. This off-grid technology can be used to produce hybrid grid-connected inverter systems.
- Micro solar inverters- These are small-sized solar inverters that are attached to individual solar panels directly. These inverters work independently and hence, they are a great option for roofs that have slightly complex structures, or shade issues. However, the reason that these inverters are not as popular in India, is because of the high price at which they are sold.
2) Output type
The solar inverters are further divided, depending on the kind of output they have. This section talks about the 3 kinds of outputs in solar inverters.
- Sine wave– Your local utility company or any generator usually has this kind of output that is called the sine wave. This output makes the inverter compatible with almost all electrical appliances, in the house or office. The sine wave is required by most light, as well as heavy appliances to work to their fullest potential.
- Modified sine wave- As the name suggests, the modified sine wave is another version of the sine wave; the only difference being that it has a square pattern. While inverters with this output are compatible with a lot of appliances, they do consume more power and hence, limit the efficiency of the appliances.
- Square wave– The cheapest solar inverter that you will find in the market is sure to have the square wave output. While this might be pocket-friendly for many people, it does not support many heavy appliances and hence, might not be a good purchase for the long term.
Efficiency is another important factor that you must take into consideration before buying the best solar inverter in India. The ratio of the output power to the input power is what will tell you the efficiency of the solar inverter. The load on the inverter determines its efficiency to a large extent. Since some power is always lost because of the generation of heat, 100% efficiency can never be achieved.
There are two power requirements that the solar inverter should meet – one is the peak power and the other is the typical power. The maximum amount of power that the inverter can supply within a fixed period of time, is known as the peak/surge power. Heavy appliances like pumps or refrigerators require this surging power to start the motor.
On the other hand, the power that is supplied at a standard and steady rate is called the typical power. This tends to be far lesser than the peak power. If you are looking for the best solar inverter for a home in India, then you can buy one with 50 watts power supply – as that is enough.
5) Power rating
Solar inverters are used for various purposes, both at home and other larger, institutional spaces. To suit every purpose, they are available with a power rating ranging from anything between 50-50000 watts. If you are planning to buy a solar inverter for your home, then you can easily work with less than 11000 watts. Most standard solar inverters come with a power rating of 50-5000 watts.
6) Internal protection features
Every electric appliance is constantly under the threat of some damage or other, especially heavy appliances. You must purchase a solar inverter that protects the various components from getting damaged due to lightning surges, overload, and so on.
7) Battery life
The battery life of the solar inverter is yet another factor that must be taken into consideration before buying any model. The battery life determines how long the inverter can function using the power supply. The number of cycles or charges that the inverter requires illustrates the battery life of the solar inverter. The unit used to express these cycles is usually milli-ampere per hour, or mah.
Any expert or previous user of solar inverters will advise you to buy a solar inverter with long battery life. Since these batteries use elements like nickel-hydride, lithium-ion, and so on, they tend to consume less power. Thus, these batteries are preferred.
8) Manufacturer’s warranty
Before buying a solar inverter, you must check for the manufacturer’s warranty. The best solar inverter company in India will provide you with a good warranty that lasts for many years. If you find such brands and products, then you should choose them without any delay. However, do not make these decisions in a hurry, and try to compare the warranty period offered by different brands. Settle for reputed brands that provide years of warranty.
Your budget for buying a solar inverter will largely determine the kind of inverter you get and its features. With a big budget, you can always go for the high-end models that provide a longer battery life, along with various advanced features or options. With a lower budget, you can still find inverters that meet your requirements.
8) Solar System Monitoring
There is some form of remote monitoring that every solar inverter provides, which helps to track the performance of the device. You need to track its operations and performance with the help of a monitoring system that is accurate and reliable. Check for the solar system monitoring before buying any particular model.
