All About Three-Phase Solar Inverters: Do You Need One?

Gone are the days when we only power a few items in our homes. Nowadays, almost everything in our home runs on electricity. If your home is running on solar energy, or you plan to make a switch to solar and install solar PV panels on your property, then you also need to think about the inverter.

The inverter is part of your solar system and is crucial in generating power for your home. Here, we will talk about a three-phase solar inverter.

Most Australian homes have a single-phase energy supply, which means they only have one live wire from the grid. On the other hand, a three-phase supply has more power to pull from the grid with its three live wires. Therefore, it can power even more appliances.

What is a 3 phase solar inverter?

Basically, it’s an inverter that converts Direct Current (DC) electricity generated from solar panels to Alternate Current (AC). What makes it different from a single-phase inverter is that a 3 phase solar inverter distributes it across a three-phase power supply.

How do you know if you need a three-phase solar inverter?

It’s easy—you only need to look in your switchboard and count the poles on your main switch.

Remember that a home with a single-phase power supply can’t have a three-phase solar inverter. On the other hand, a three-phase supply has three options to choose from: a single-phase solar inverter, micro inverters, or a three-phase solar inverter.

We recommend that you choose a three-phase inverter if you have a three-phase home because it will be more beneficial for your home and the grid. With a three-phase solar inverter, the capacity is spread across the three wires; hence, you don’t need to push solar energy too much. As a result, you can increase the local grid voltage less, plus you get less throttling or tripping that occurs with over-voltage.

With a three-phase inverter, you can produce more solar power with high voltage.

It is important to note that a three-phase inverter is not required if you have three-phase power. It is recommended due to its advantages, though you will be paying more than a standard single-phase inverter.

Energy Matters has a list of the best solar inverters in 2022 that you can choose from today. We recommend you get to know the brands before purchasing to ensure maximum efficiency and reliability.

The advantages of a three-phase inverter

There are more benefits to a three-phase solar inverter. One, it has a higher capacity, increasing the ability to generate more power. Second, you can expect constant power because of the ease of distribution.

Third, compared to single-phase inverters, this is more efficient because a three-phase solar inverter has a limit to what it can power efficiently.
