Best Solar Inverters 2024 | Reliable And Intuitive Inverters

A solar inverter changes direct current (DC) electricity into alternating current (AC). The inverter is an important system component because solar panels are designed to convert sunlight into DC energy. Still, your home requires AC to power all your lighting and appliances. The solar inverter converts the DC electricity produced by the solar panels into 240V AC electricity, which can then be used by the property/household, exported to the grid, or stored in a solar battery storage system.

solar inverters

  • The sun shines on the solar power panel, generating Direct Current (DC) electricity.
  • The DC electricity is fed into a solar inverter that converts it to 240V 50Hz AC electricity.
  • The 240V AC electricity is used to power appliances in your home.
  • Surplus electricity is fed back into the main grid.

Home battery and hybrid systems are also becoming more popular, but batteries are still developing, and most solar installations still need a dedicated solar inverter.

The major benefit of a more extensive solar PV system is that it will be simple to add a solar battery, utilise your solar inverter’s capability to its fullest extent, and generate more power during the day so that you won’t be as dependent on grid electricity. You can start making the most of your solar PV system by installing a solar battery, like the GoodWe, Enphase, sonnen, Fronius, Fimer and Sungrow.

Many solar inverter products also have a Wi-Fi monitor, which gives you real-time data about the solar power generated. It’s even better when you have a powerful solar panel that can measure the energy used to produce electricity.

What is an inverter used for?

Every solar power system must have solar inverters. They carry out two essential tasks:

Conversion from DC to AC

All solar panels generate Direct Current (DC), which must be converted into alternating current (AC), the type of electricity your home can use by a solar inverter.

Maximum Power Point Tracking (MPPT)

The amount of sunlight and solar panel temperature that affect how well solar panels work change throughout the day. It implies that the voltage and current that a solar panel may produce could also change constantly. The solar inverter dynamically chooses the mix of the two that will provide the maximum electricity using a process known as Maximum Power Point (MPP) tracking.

Criteria used to select the best solar inverters

Choosing a solar inverter can be accomplished by examining the following criteria.

  • Efficiency, quality & reliability
  • Service & support
  • Monitoring
  • Warranty
  • Features
  • Cost
  • Size option

Solar Inverter Technologies

String Inverters

The most common type of solar inverter used in residential solar panel systems is the string inverter because each installation typically calls for one. Several solar panel strings connect to a single inverter. Then, for domestic usage, it transforms DC into AC.

Micro Inverters

Each solar panel needs a small inverter called a microinverter to maximise its power at the module level. Even with partial shading, each solar panel still generates more electricity. Each panel’s voltage output is optimised using a microinverter to maximise output. Since each micro-inverter is connected to another, the system keeps converting DC to AC even if one microinverters fails.

Central inverters

Although they are larger and can sustain more than one string instead of just one, they are closely similar to string inverters.

Contrary to string inverters, the strings inside are united into a bix, with the DC power moving towards the central inverter box, where it is converted to AC electricity. These primarily serve business rather than domestic purposes. These are typical of commercial facilities and utility-scale solar farms.

Battery based inverter

A battery bank is necessary for battery inverters to operate. It transforms the battery bank’s DC electricity into AC energy. They can deliver power even during a power outage like hybrid inverters. Battery inverters have the drawback of interfering with the phone, radio, and television reception due to their buzzing noise. Installing sine waves will help you reduce interference.

Power optimiser

Power optimisers can be installed in systems with strings of panels and a string inverter even though they are not inverters. Like microinverters, they ensure that the output of the remaining solar panels in the string won’t be impacted if one of the panels is shaded, dirty, or fails in some other manner.

Solar PV systems and required inverters

Grid-tied inverters are intended for grid-tied solar systems, the most common system type. When necessary, they import utility electricity from the grid and maintain a two-way interaction with it, exporting solar energy to it.

Hybrid inverters function with hybrid solar systems, also known as multi-mode inverters, battery-ready inverters or solar-plus-storage systems. They can charge and draw electricity from a battery arrangement and have the same functionality as a grid-tie inverter.

Off grid inverters are utilised in off-grid solar systems, also known as entirely independent solar power systems, to provide backup power during grid outages.

An off-grid inverter cannot be linked to the grid and must have a battery backup to operate.

Seeking the perfect match

With the information above, you’re well-equipped to navigate the world of solar inverters. But remember, your journey doesn’t stop here. Consulting a qualified solar installer is crucial for getting the best solar inverter in Australia for your specific needs and setup. They can assess your property, analyse your energy usage, and recommend the ideal inverter-panel combination to maximise your solar savings and contribute to a brighter, cleaner future for yourself and the planet.

Remember, the “best” solar inverter is subjective and depends on your specific needs and priorities. Consider factors like budget, roof layout, shading concerns, and future battery storage plans before making your choice.

Understanding your solar inverter brands

Learn all there is to know about your inverter once it has been installed. Learn the meanings of the indicator lights and displays often present on them.

It’s a good idea to regularly check in on your solar system, whether you use powerful software monitoring or just a visual inspection of the inverter’s indication panel. Early detection of issues will enable you to address them and change your electricity use to maximise the use of your solar power. You don’t want to learn the hard way from an electricity bill that your system hasn’t been working properly, and you’ve been using grid power rather than solar power!
