STRING INVERTER SOLUTIONS

If you’re considering a solar installation or upgrade, understanding the different types of solar inverters available is essential. These devices are vital in converting solar energy into usable power for your home. Here are the primary solar inverters commonly found in the Australian market:

String Inverters:

String inverters are the most prevalent type in Australia. They connect arrays of solar panels in one or two strings to a single inverter. Brands like Fronius, SMA, Sungrow, and Goodwee offer reliable options. While string inverters are cost-effective and widely used, they are susceptible to shading issues, and if one panel underperforms, it can affect the entire string’s performance.

Microinverters:

Microinverters are another popular option, with each solar panel having its dedicated microinverter. Brands like Enphase dominate this segment. Microinverters offer increased efficiency and resilience against shading, as each panel operates independently. However, they come with a higher upfront cost and additional installation complexity.

Hybrid Inverters:

Hybrid inverters combine the functions of a battery inverter and a string inverter into a single unit. They are suitable for integrating batteries into your solar system. Brands like SMA, Fronius, Sungrow, and Goodwe offer hybrid inverters. While they offer cost-effective integration with batteries and streamlined installation, they may have limited availability and require additional monitoring equipment.

Power Optimisers:

Power optimisers are devices attached to solar panels in a string, optimising performance and minimising shading effects. Brands like SolarEdge and Tigo provide options in this category. Power optimisers offer enhanced panel-level monitoring and shading resilience but require additional equipment and are not standalone inverters.

Choosing the Right Solar Inverter:

When selecting a solar inverter, consider your system’s size, efficiency, and warranty, and avoid oversizing to prevent unnecessary expenses and inefficiencies. Your installer can provide personalised recommendations based on their expertise and manufacturer relationships.

Understanding the types of solar inverters available and selecting the right one for your needs is crucial for maximising the efficiency and effectiveness of your solar system. Consult your trusted solar installer for personalised advice tailored to your requirements.
