As you look for ways to incorporate more solar energy power into your home or daily life, it’s always important to know exactly how things work. A commonly misunderstood piece of solar energy equipment is the solar grid tie inverter.

Having questions about all these different solar energy technologies is common—but we’re here to make sure you understand each and every part of solar grid tie inverters! While they may seem difficult to process at first, don’t worry—they’re really not! Step by step, we’re going to show you what solar grid tie inverters are, all while we show you how they work efficiently.

What is a solar grid tie inverter?

To start things off, let’s talk about what a Solar Grid Tie Inverter even is. A grid tie solar electric system helps turn sunlight into electricity by using solar panels and a power inverter, along with many other smaller components. This all happens while your home (or solar powered building) remains dependent on the local grid, or utility. This is different from off-grid systems, which means that your power is not hooked up or dependent on any other utility power.

Why should you install a solar grid tie inverter system?

The main reason people decide to install and rely on a solar grid tie inverter system is to save money as much as possible. While this is already done by converting to using solar energy as much as possible, it’s even more possible to save money by utilizing a solar grid tie inverter. The great thing about these inverters is that they are able to keep the energy as renewable as possible. This means that any excess power produced is pushed back into the grid, which can turn your meter backward. This can result in lower electric bills.


Recently, having solar grid tie inverters installed in your home as also made the home’s value increase quite significantly. Having this installed in your property raises the value. If you’re looking to sell your home and are finding ways to make your home more valuable and attractive to potential buyers, having a solar grid tie inverter will really help.

Finally, you should install a solar grid tie inverter system because solar energy is the best way to go. I probably don’t have to tell you that. Solar energy is a green and clean source of power all around. By using solar energy in your everyday life, you’re helping to protect the environment in an efficient and profitable way.

How does a solar grid tie system work?

Let’s learn how these solar grid tie inverters work, step by step.

To start small, let’s talk about how the inverters get the energy in the first place. The solar panels that you install on your rooftop are the first step of having a successful solar grid tie inverter system. These solar panels collect the sunlight that shines on them and produces a direct current (DC).


Now, this DC needs to be converted into alternating current (AC) in order for your home to be able to use electricity. This conversion happens through the power inverter that you have installed—all without you lifting a finger. Once the DC is converted into AC by the power inverter, you are able to use this electricity for your household. This process is simple, fast, and efficient—and happens in your house quietly and effectively every single day without you having to do any work at all. The perks of having solar, huh?


Now, the great thing about the solar tie inverter system is the ability to use the extra power generated, just like we talked about above. If there is every any excess of power produced in your home, this excess is sent back out into the utility grid. This, again, sends your meter backward and can lower your electricity bill. Since you’re on the grid, this means that your neighbors can then use the clean and efficient solar power that was sent back into the grid from your house or residence. Again, this all happens quietly and automatically. You would never know if your house produced more energy and needed to send it back to the grid. And, you never have to lift a finger.

This back and forth that the solar grid tie inverter partakes in is called “net metering.”

The items you need for a successful solar grid inverter system

To have an efficient and economical solar grid inverter system, you need to make sure you have the proper equipment installed and ready to use. These items include (but are not limited to) rooftop solar panels, solar panel mounts, solar panel trackers, power inverters, a grid disconnect, a combiner box, and a DC disconnect.


It is also worth mentioning that you should always plan accordingly if you’re deciding to invest in solar rooftop panels to get the ultimate successful solar grid inverter system. As you know, sunlight needs to be available for the solar panels to even work—and for the whole system to even work. Therefore, before installing all of your solar panels, plan. Go around your house and see if there are ever shadows during the day where you want to install these panels. Be wary of trees or shadows that seem to cover your roof. The best way to use solar energy efficiently is to make sure they are getting all the sun in the world.

It should also be noted that, as solar energy production expands with technology advancement, there are a lot of different prices and brands out there. Of course, the high-quality options are always the most expensive. You should take reviews and the price of the components into consideration as you plan to bring a successful solar grid inverter system into your home.

However, once you finish installing this successful system, and once you incorporate solar energy into your everyday life, you won’t regret it. From the efficient energy being produced to the lower electric bills, you’ll wonder why it took so long for you to switch to solar energy in the first place.
