About Sungrow

Sungrow Customer Service: 1800 786 476

Sungrow Power Supply Co Ltd is a Chinese company that was established in 1997 and operates in several different energy-related niches, including wind power conversion, inverter production for photovoltaic systems and energy storage.

The company says more than 340 GW of Sungrow inverter capacity had been installed worldwide as as at the beginning of 2023. To give a sense of how rapidly the firm's manufacturing capacity has grown in just the last couple of years, 154GW of capacity had been deployed by the end of 2020.

Walking the clean energy talk, Sungrow has also committed to sourcing 100% renewable electricity for its operations by 2028.

Sungrow In Australia

Sungrow has been present in the Australian solar inverter market since 2012. Its Australian operations are based in North Sydney, NSW. So, should you need technical assistance or in case you have any questions about their warranty policies, you can contact Sungrow easily by calling or shooting them an email.

Australian customers can choose from a pretty solid range of solutions, including single-phase and three-phase inverters in the SG series. Sungrow's inverter range also includes hybrid models available in the SH series.

Sungrow Hybrid Inverter Cybersecurity Flaw

While Sungrow has enjoyed signficant success in Australia, it hasn't always been sunshine and puppies for the company. In early January 2020, an engineer based in Brisbane revealed he had identified a series of security flaws in Sungrow's hybrid inverter, model SH5K-20. In March 2020, Sungrow announced they had shipped a firmware update that fixed the flaws.

Sungrow Warranty Notes

Sungrow generally offers a standard product warranty period of five years from the date of installation and no more than six years from the manufacturing date of a solar inverter - so that's something worth checking.

However, in April 2020, the company announced it was offering 10 years’ warranty for some inverter models purchased from 1st April 2020 and installed in Australia. Eligible Sungrow inverter models can be identified here.

If you have problems with your Sungrow inverter, your first port of call is the original  installer. Despite what some might say, if the installation company is still in business then they are the ones liable for the repair/replacement of a faulty inverter assuming it is still within its warranty period. If your original installer is no longer in business or is uncontactable, you'll need to lodge a warranty claim with Sungrow.

In order to do so, Sungrow advise you must arrange an installer to test the solar inverter to determine if it is faulty. Sungrow can help you find someone in your area if you call them on the number listed above. If a fault is confirmed, Sungrow will work with the installer to arrange a replacement inverter. Notably - you are not compensated for the out of pocket cost of the initial testing.

My Recommendation

Given the quality of the company's products and support along with generally positive feedback from installers and customers over years (you can read Sungrow customer reviews below), Sungrow is currenly listed as a SolarQuotes recommended solar inverter brand. 

In the 2024 SQ Installers' Choice Awards, Sungrow took out the top spot for best value inverter for the fourth year, and second place in best after-sales support.  For 2025 we simplified the award question and simply asked installers, "If installing a system on your own house today, which brand's inverters would you use?"  Sungrow took second place.

If you're an owner of one of the company's products, we invite you to share your experience with others. You can add your Sungrow solar inverter review by clicking the "leave a review" button at the top of this page.
