Are you setting up a solar system? You’ll need a solar inverter too. Luckily, we can help you choose the best one for your needs.
What Is A Solar Inverter?
A solar inverter is the part of a solar power system that converts solar power into electricity for your home.
The solar inverter changes DC (direct current) electricity to AC (alternating current) electricity. AC electricity can then be used to pass through the electric circuits in your home and run your appliances.
Solar inverters convert electricity by running DC electricity through a transformer which lowers the voltage and converts it to AC. The DC electricity also runs through two or more transistors which are rapidly turned on and off to feed the two different sides of the transformer.
What Are The Types of Solar Power Inverters?
There are a few different types of solar inverters, and it is essential to know about these in order to determine which is best for your home. Below are the different varieties:
- String Inverters – String inverters are the most commonly used inverters. They are also the oldest and work by connecting the inverter to rows of solar panels. Keep in mind that if one panel is not performing, this can jeopardise the performance of all the panels on that row. So, it’s best not to use this inverter if one or more of your panels will be in the shade throughout the day.
- Micro Inverters – micro inverters are fitted straight to each individual panel on the roof. The DC energy is converted to AC energy on the roof without travelling to the inverter. This means that all panels have an independent link to the solar inverter, and therefore if one is not working properly, this will not affect the function of the other panels. You can install more panels easily by using this kind of inverter; however, they can be expensive.
- Hybrid Inverters – These inverters put your excess electricity into a solar battery to be stored for later use, or you have the option of selling your excess electricity back to the grid. They send electricity to and from your battery; this way, you don’t have to buy a battery inverter. These are the most functional kind of inverter.
Choosing The Best Solar Inverter For Your Home
A suitable inverter should perform two functions; turning DC electricity into AC electricity to be compatible with your electric circuits and home appliances, and maximising the available energy generated from your solar panels.
When installing your inverter, it is important to store it in a cool place. Inverters are often stored in attic spaces, where they can sometimes overheat and are hard to reach to check they are working correctly.
You will need to make sure the watt capacity of your solar inverter is equal to or above your solar system’s watt rating.
Many string inverters are now accessible via wifi, so you can check the performance of your panels from your phone, which is a major benefit. If you have a solar battery, a hybrid inverter could be the right choice for you as they send electricity to and from your battery. If you get a hybrid inverter, you won’t have to invest in a battery inverter. This can streamline how many elements you have to purchase for your solar system.
If you are looking to set up a solar system, you will find that string inverters are the least costly option and have other added benefits.
Solar inverters usually cost in excess of $1000 and are a necessary part of any solar panel system, so it is important to choose the right one for your needs. Explore SolarPath’s range of solar inverters and contact us for more information.
