What Is A Solar Inverter And How Does It Works?

With the increased interest in renewable sources of energy, the interest in the solar system has also shot up exponentially. The ability of the sun to power almost all the electrical appliances in your home is such an environmental plus.

While you might be happy to use solar systems to reduce the power consumption load on fossil fuels, do you have any idea what solar systems are made up of and how they work?

Solar systems are made up of solar panels, a solar inverter, and a rack to keep everything in place. They may also contain batter, depending on the system. While most people are aware of what solar panels are and how they work, only a few individuals actually know what solar inverters are all about.

Considering how important the solar system is, we have thought of putting together a little information on Solar Inverters.

What Is A Solar Inverter?

solar inverter is one of the most crucial elements of the whole solar energy system. You can even say that it’s the heart of the solar energy system. 

When solar panels are doing their job of collecting solar energy from the sun, it is the solar inverter that converts the Direct Current and Alternating Current. It is because of the conversion that the stored solar energy can be used for a variety of residential and commercial use.

With the use of solar inverters, homeowners can use solar energy to run their home appliances and power their indoor lighting.

Solar inverters play not only a pivotal role in making eco-friendly energy, but also help in monitoring the performance of the solar energy system.

Additionally, with inverters, individuals can store excess power into the batteries, which can easily be fed back to the main power grid.

Types Of Solar Inverter

Now you know what solar inverters are all about, you must know the different types of solar inverters available on the market.

There are five different kinds.

  • Central Inverters: A central inverter is massive and used only when the home needs hundreds of kilowatts of volume. They are not meant for residential use and are mostly used in commercial buildings. These inverters come with a metal cabinet, with each metal cabinet capable of handling 500kW of power.
  • Battery Inverters: A battery inverter is a perfect fit if you are looking for residential use. A battery converter converts the power to 230 V and feeds it to the switchboards. 
  • Hybrid Inverters: Hybrid inverters, also known as Multi-Mode inverters, are pretty common in Australia and allow the user to connect the batteries. The system engages with the connected battering using DC Coupling.
  • Micro Inverters: As the name suggests, micro inverters are small in size and manage each solar panel individually. The benefit of using micro-inverters is that they offer you to optimize each solar and more energy (even in shady regions).
  • String Inverters: String inverters are mostly used for residential purposes. They are called string inverters because a string of solar panels can be connected to them.

How Does A Solar Inverter Work?

A solar inverter takes direct current (DC) from the solar panel and converts it into alternating current (AC). The importance of solar inverters can be measured by the fact that home appliances work on AC. 

If we want to be more technical, this is how it looks.

The sun shines down on solar panels that have photovoltaic cells. These cells are made up of semiconductors layers of gallium arsenide. When the sun shines, these semiconductor layers absorb the sun’s heat and send the energy to the PV cell.

This energy runs around and lets the electron loose. The electrons now travel between the negative and the positive charge, producing DC electric current.

Once this energy is produced, it is directed to stores in batteries or sent directly to an inverter.

When the energy is sent to the inverter, it is in the form of DC. DC electric currents are of no use in your home. This is why the inverters grab the energy and pass it through the inverter. The inverter changes the DC current to AC.

Advantages Of Solar Inverters

  • Solar energy has constantly helped in reducing the greenhouse effect and global warming.
  • By using solar-based devices, you will save not only energy but also money.
  • A solar inverter is used to convert DC current to AC current. This supports people who use only a partial amount of electricity.
  • The multi-functional solar inverter converts DC to AC. That means it offers its services for both residential and commercial use.

Disadvantages Of Solar Inverters

  • One of the major disadvantages is its initial cost. Before you can start leveraging the profit of solar energy, you first need to install them. And the installation sure costs a lot of money.
  • Solar inverters can work efficiently and produce DC electric current when the daylight is strong. That means during the rainy season of cloudy days, the efficiency of a solar inverter will drop.
  • Solar panels work on the amount of sunlight they can absorb. To get the most out of it, you must lay out solar panels on a large surface area.
  • Solar inverters can work on cloudy days, but if you want the battery to charge itself, you need sunshine. The sunshine should last at least 10 hours.

Solar Inverter Warranty

This is an important thing you need to know about Solar inverters. Most grid-connected inverters last from 15-2- years. And if we are talking about realistically, they should all at least last for 10 years. 

Depending on the inverters, their life span varies, and so does the warranty. Depending on what solar inverter you buy, you can expect a 5-12 years warranty.

Before you buy any solar inverter, take a look at the features and see whether or not they are matching up with your needs. Always remember that the longer the warranty, the better protection you have.

Now you know what solar inverters are all about and how they work. We have also included their advantages and disadvantages to add more information. If you have any queries, drop them in the comment section.
