Solar inverters are devices that convert the direct current (DC) output of a photovoltaic (PV) panel into an alternating current (AC). Household appliances and electrically powered equipment can use this alternating current.

AC is the type of electricity that we use in our homes. Therefore, it is necessary to have an inverter to be able to use solar power. Inverters come in all shapes and sizes. There are a lot of factors to consider when choosing the right one for your home. Below, we will discuss what solar inverters are, why they’re important, and some of the different types available on the market. We will also talk about how you can choose the right one for your needs.

What are solar inverters?

Solar inverters are a vital component of any PV system. This is because they allow the DC electricity generated by the PV panels to be used by AC-powered devices. To use the electricity generated by your solar panels, you will need a solar inverter to convert the DC into AC. Solar inverters are typically installed outdoors, near your solar panels. They are typically maintenance-free,. However, it is important to keep an eye on them to make sure they are functioning properly. If you notice any problems, contact a qualified technician for help. By choosing a quality solar inverter and keeping it well-maintained, you can ensure that your home solar power system runs smoothly and efficiently for many years to come.

The different kinds of solar inverters

Solar inverter’s popularity is growing as PV technology becomes more mainstream. There are five different kinds, each with its own unique benefits to offer you.

1.       Battery inverter

If you are looking to add a battery to your existing solar system or keep your battery separate from your solar panels, a battery inverter is the best solution. Battery inverters take the power from your batteries and transform it into 230V AC. It can then be fed into your switchboard. This is a more efficient way to use power, and it also helps to protect your batteries from overloading. Battery inverters are available in a variety of sizes and capacities. Therefore, you can choose the one that best suits your needs.

2.       Central inverters

Central inverters are large devices that are used in systems that require hundreds of kilowatts of capacity. They are not for home use and look like giant metal cabinets. Each cabinet is capable of handling about 500 kilowatts of electricity. Commercially, they are often employed for large-scale installations or utility-scale solar farms.

They are an important part of the solar power industry because they help to convert direct current (DC) into alternating current (AC). This conversion is essential for sending electricity to the grid. Central inverters are also less expensive than string inverters, making them a more cost-effective option for large-scale solar farms.

3.       Hybrid inverters

Hybrid inverters are a type of inverter that allows you to connect batteries to your solar system. They are sometimes known as ‘multi-mode inverters,’ and they are relatively uncommon in regions like Australia. These inverters work by ‘DC coupling,’ which means that the inverter’s electronics manage the battery’s charging and discharging.

This can be beneficial for several reasons. First, it can help to prevent voltage drop. It can occur when the batteries are charged and discharged at different rates. Second, it can improve the overall efficiency of the system by allowing the batteries to be more effective. Finally, it can reduce the amount of energy lost through heat dissipation.

4.       Micro-inverters

Microinverters are small electronic devices that convert direct current (DC) electricity generated by a solar panel into alternating current (AC) electricity. A single microinverter is attached to each solar panel in a PV system, and the AC electricity produced by the microinverter is then fed into the home or business’s main electrical panel. Microinverters offer a number of advantages over traditional central inverters, including higher energy yields, improved system reliability, and simplified installation and maintenance.

One of the main benefits of using microinverters is that they allow each solar panel to operate independently. This means that if one panel is not cleaned or shaded, it will not affect the overall performance of the system. Additionally, because each panel optimizes individually, microinverters typically have a higher energy yield than central inverters.

Another advantage of microinverters is that they improve system reliability. With a central inverter, if one panel fails, the entire system will go offline. However, with a microinverter-based system, only the affected panel will shut down.

5.       String inverters

As the name suggests, string inverters are attached to a string of solar panels. They are the most popular type of inverter for residential usage, and each solar system typically includes one string inverter. String inverters are known for their reliability and efficiency. Moreover, many often use it in commercial applications as well. String inverters may not be the newest or most cutting-edge type of inverter on the market. However, they are still an excellent choice for many homes and businesses.

What should you look for in a quality solar inverter?

There are a few things to look for when comparing different brands of inverters, as well as different sizes and types. The CEC authorization is one thing.

  • The Clean Energy Council (CEC) has authorized several inverters, and Clean Energy Regulators have several them. It is acceptable and certified for the climates in line with the applicable regional Standards and is of excellent quality if it is CEC approved.
  • The size of the inverter is determined by a variety of parameters. However, make sure that the inverter you choose can manage the amount of electricity that a solar power system may generate.
  • Another feature to look for in a high-quality solar inverter is weather resistance. It is obvious that it is of the highest quality, and it provides greater versatility to perform well in all conditions.
  • Other factors to consider are the guarantee, pricing, display, and quantity of information offered, as well as whether or not it can be upgraded as necessary.

With all these qualities, you can be content with the longevity of your solar panels once you have identified the ideal option for your solar PV system.
