Sungrow - Inverter Reviews

Finn's Sungrow Inverters Review & Verdict

Finn Peacock has been a Chartered Electrical Engineer since 1998, and is ex-CSIRO

In my opinion, a solar power system that will be on your roof for 30+ years deserves the best inverter you can afford.  But if you want to save the ~$1,000 premium that a high-end inverter brand such as Fronius will command, then my favourite budget inverter brand is Sungrow - although Goodwe are snapping at their heels.

Sungrow solar inverters are reliable and well supported in Australia with excellent warranties.

Sungrow hybrid inverters when paired with the impressive Sungrow batteries are an excellent way to get home storage for thousands of dollars less than a Tesla Powerwall and separate solar inverter. 

Sungrow Inverters: Pros & Cons

  • Excellent value.
  • Well supported with local office and 10+ years Australian history.
  • Good monitoring platform.
  • Capable hybrids with AC coupling available for more solar on backup circuits.
  • Well regarded amongst installers.
  • Tech support can be patchy with some script readers in place of actual technicians.
  • Failure rate and subsequent warranty work has made some installers gun-shy. (These issues can both be attributed somewhat to stellar growth)
  • Plugged connections can be fiddly to terminate, especially when hybrids require very large supply cables which must be broken down into small cables.
  • Hybrid back up circuits are limited to their rating regardless of if there is grid or no grid. The inverter doesn’t have a higher “pass through” rating when grid connected.
  • This limited capacity means the backup circuit struggles with high inrush loads such as motors, i.e. household water pressure pumps. (Savvy installers will alleviate this with a changeover switch or contactor)

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 2023 SQ Installers' Choice Awards, Sungrow took out the top spot for best value inverter for the third year, and second place in a new category, best after-sales support.

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.

The fan is noisy but only runs when the inverter is working hard.
The inverter puts out a lot of heat. I think the shed wildlife will like being near it in winter.

As with so many needs to "phone home" for data and you have to use their server to see what your stats are; next time we'll be sure to invest in an inverter that doesn't need to phone home.
