The solar inverter is an electronic device that is a gateway for all the solar energy your panels generate. It is responsible for directing the energy to your home’s appliances or, in the event of excess energy produced, to the mains grid. Solar hybrid inverters also feature vital safety shutdown electronics, including Anti-Islanding Protection.
Given its crucial role in the solar energy system, selecting a solar inverter capable of handling the task and providing the best value for your investment is paramount.
Moving on to technical details, here are the three best kinds to invest in for your home:
In a residential solar power system, one string inverter is usually installed. The reason it is called a string inverter is because strings of solar panels are connected to it. These are typically wall-mounted near the meter box, but the location may vary depending on the installation scenario. To compare inverters side-by-side, you can do so here.
These are massive inverters used in solar systems with a capacity of hundreds of kilowatts or even megawatts. Large metal cabinets can handle up to megawatts of capacity per enclosure. These inverters are not used for home installations but for large commercial or utility-scale solar farms.
Also known as multi-mode inverters, these allow you to add batteries to your solar power system. The hybrid inverter interfaces with the battery using a technique called “DC coupling,” where its components handle the battery’s charging and discharging. There are only a few options available for hybrid inverters in the Australian market, but the range will grow as battery storage becomes more popular.
These are small solar inverters, approximately the size of a paperback book, and one is needed per solar panel. The main advantage of microinverters is that they optimise each panel individually, resulting in more energy. Although microinverters can be useful in partial shade conditions, some newer and better quality string inverters can handle these conditions better. Enphase is considered the best brand for microinverters.
Optimised String Inverters
These provide similar performance benefits to microinverters but use slightly different technology. An optimiser system requires a string inverter, but optimisers are attached to the back of solar panels, optimising each panel’s output under various conditions. Huawei and SolarEdge optimisers require optimising every panel in an array, but Tigo brand optimisers don’t (and are inverter-agnostic), which keeps costs down. The Tigo option is particularly useful if only a few panels are impacted by shade.
Suppose you want to retrofit batteries to your solar power system or keep your battery system separate from your solar panels. It transforms battery power into 230V AC and feeds it into your switchboard instead of grid power where possible.

Since several types of inverters are available for solar power systems, consider cost, efficiency, and compatibility with your system when choosing an inverter. Whether you opt for a string inverter, microinverter, optimiser, or battery inverter, the right choice will help maximise your solar power system’s energy output and overall performance.
