How to Buy the Best Solar Inverter

Thursday, August 4, 2022

While solar panels can be a great investment for your home, you may find that during a blackout, you still lose power. A solar inverter can keep your power running when the main electricity grid is down.

What is a Solar Inverter?

A solar inverter is a device that helps convert the energy from the sun into usable electricity for your home or business. It does this by splitting the incoming solar power into DC (direct current) and AC (alternating current), then converting the AC to usable household or office electricity.

The basic principle behind how a solar inverter works are quite simple. The inverter takes in sunlight (which contains high frequencies) and converts it into lower frequencies that can be used by appliances in your home or office. This means that you can use all of the power provided by the sun to run your appliances, without having to worry about frying your wiring or damaging your electronics.

The best solar inverters in Australia typically have a high-performance rating, meaning they can handle a lot of energy quickly and efficiently. They're also likely to be smaller, lighter, and more affordable than other types of solar power equipment. In fact, many people choose solar inverters over other types of solar power simply because they're easier to use and install.

An inverter is generally one of the more sophisticated components of a solar PV system, and it is also usually one of the first components to fail. You should expect your inverter to last five years at least, but ideally, you should get around 10 years out of them.

Types of Inverters Available

There are four main types of solar inverters available on the market, and in general, all the major brands are fine. All solar inverters should be Clean Energy Council approved and meet Australian Standard 4777.

String inverters are the most common type of inverter used and are usually the least expensive option. The inverter is mounted on an external wall, and a “string” of solar panels is connected to the one inverter.

Micro-inverters are great for solar panel systems that are in partial shade. Each panel can have its own micro-inverter, which means if a panel fails or shade, you only lose the efficiency from that one panel.

Hybrid inverters are string inverters with the additional capacity of connecting battery storage to the solar PV system. If you haven’t yet got a battery, it is worth considering the compatibility between your inverter and battery options.

Battery inverters are great for those adding a battery storage system later on.

What Size Inverter do I Need?

As a general rule of thumb, your inverter size should match your solar PV system size. So if you have a 3kw solar system, a 3000W inverter is your best option. A 6kw system will work best with a 6000W inverter and so on. This allows all the DC current to be transformed into usable AC current for your home or business.

If you haven’t yet had solar installed but are interested in also installing an inverter, have a chat with the professional team at Limitless Energy. We can help you work out which size system and inverter will meet the power requirements for your family.

Where Should a Solar Inverter be Installed?

Solar inverter installation should be done in a place that is away from direct sunlight with plenty of natural airflow and ventilation. You should choose an area that can be easily accessed for maintenance and somewhere moisture resistant.
