🌞 What Is A Solar Power Inverter?

Solar power energy plays a very crucial role in our lives.  But, when talking about solar system equipment, it is not only solar panels that are important, but solar powered inverters play the same role. Here, we will discuss What is Solar Power Inverter?

Solar power inverters convert the energy from solar panels into the usable electric energy that can be used by appliances, lighting, electronics, etc. in the home.

In the absence of solar inverter, we can receive energy from the sun into the solar panel, but we cannot use that collected solar energy into our home appliances, electronics, and lightings.

The solar inverter is an essential part of the whole solar PV system, and this is also the part most likely to have issues as they are located in different weather conditions such as humidity, extreme heat, and rain.

The solar powered inverter is the electrical converter type that can convert the variable direct current (DC) power into the utility frequency usable alternating current (AC) power.

When sun rays shine on the solar photovoltaic (PV), electrons get into their work and produces direct current energy.

Mostly, houses use alternating current (AC) energy, not direct current (DC) energy. And, the energy which is produced by solar panels is direct current (DC) energy. Here, the solar inverter comes into existence.

First, your solar panels collect the sunlight and turn it into energy. Then, it sends electricity to the solar power inverter, which converts DC energy into AC energy.

As time passes, more and more people are installing solar power inverters into their homes as it can save their too much amount of money. Before installing it, one should be aware of different types of inverters, the process and which PV system would be perfect for him/her.

Generally, the main task of all the solar power inverters is to convert direct current (DC) solar energy into usable alternating current (AC) energy for homes. If you are planning to set up solar inverter at your home, you will need to select it from different solar power inverter technologies.

All have the same function, but each of them works a bit different from one another. To select for your solar panel system, below given are different types of solar inverters:

1. String Inverters

The String inverters are also known as a standard centralized inverter. Most of the small solar energy system use string inverter technology.
In this solar technology, each solar panel is wired into strings. When the solar panel produces energy from the sunlight, it will go into the single inverter.
And, at last, the inverter converts the Direct current energy into alternating current energy. This kind of solar inverter technology is of meager cost, and through this, the inverter is also very easy to maintain.
This solar system technology is advisable for those house owners who are looking for low-cost solar PV systems, and also for those houses that have direct sunlight throughout the day.

2. Micro-inverters

Micro-inverters are high-performance inverters with complex systems. This system is perfect for houses with improper and small space on the roof.
In micro-inverter PV systems, a small inverter is being installed at the site of each solar panel. As we have seen, the string inverter system sends the energy from the solar panel to a single inverter.
While solar PV systems with micro-inverters convert direct current (DC) energy to alternating current (AC) energy on the roof only.
String inverters are of meager cost, while micro-inverters are comparatively of higher price than string inverters. Also, you might find difficulty in repairing, and maintenance as micro-inverter will be located on the roof.

3. Power optimizers

Power optimizers solar PV system is the combination of both, string inverters and micro-inverters. Just like micro-inverters, power optimizers are also located on the roof next to individual solar panels.
But, in power optimizers system, the energy will still be sent to a centralized inverter. Like micro-inverters, it doesn’t convert direct current energy to alternating current energy at the site of the solar panel.
Instead, it conditions the direct current energy by fixing the voltage of the electricity. Power optimizers PV system is comparatively more efficient than the system with a string inverters.
Power optimizers system can also improve the efficiency of your solar panel system just like micro-inverters. This system is best for the house owners who can pay more for the efficiency of the solar panel system.

4. Battery Inverters

If you want to keep your solar panels separate from the battery system, separate battery inverter will be the best choice for you.
The battery inverter converts the battery power into the 230V current. And, then it delivers into your switchboard.

How to choose the best inverter system for your home

You have three options for the selection of the solar inverter system for your home. As you have seen, all these inverter systems work a bit differently from one another but their main function is similar.
For the selection of ideal PV solar inverter system for your house, the first important thing is to decide how much you are willing to pay and how much you are prepared to pay for the possibility of additional maintenance.
From these three options, string inverters are of very low cost and micro-inverters is of a high price. While the price of power optimizers is higher than string inverters and lower than micro inverters.
If your home’s roof has direct sunlight throughout the day, string inverter will be the best for you. But, in string inverter, the electricity production will be reduced if one or two solar panels are not working properly.
The microinverter will be the best choice for the house which has improper and small space on the roof. The disadvantage of micro-inverters is that they are very costly and there can be difficulty in repair in the event of a problem.
A power optimizer is the combination of string inverter and micro inverter. This system can improve the efficiency of your solar power system. But, its prices are higher than the string inverter.
Hence, after considering all the above factors carefully, you should decide about the best inverter system for your home.
