Sungrow has now evolved to become one of the world’s largest manufacturers of solar inverters. Sungrow has sold over 100GW of solar energy to 60 countries, giving it a 15% global market share. This has aided in the company’s $1.5 billion valuations.

Sungrow joined the Australian market in 2012 and claims to have taken roughly 15% of the market for inverters. Sungrow is a research and development company that prides itself on being a solar industry innovator. As of June 2019, this commitment had resulted in over 1,600 patent applications.

A Quick Overview of Solar Inverters

The inverter in a solar system converts the DC electricity generated by solar panels into grid-compatible AC electricity. String inverters, hybrid inverters, microinverters, and power optimizers are the four types of solar inverters.

In the solar business, string inverters have long been the standard. They transport the power generated by solar panels to a central inverter, which converts it from DC to AC electricity that may be used to power dwellings.

Hybrid inverters have the same qualities as string inverters, but they also include a charge controller for managing a battery system. Charge controllers can be purchased separately, however hybrid inverters offer the convenience of all-in-one equipment.

What is the top performer at PV Evolution Labs?

PV Evolution Labs (PVEL) has been independently testing solar panel reliability since 2014, with help from DNV GL, and has now tested solar inverters for the first time in 2019. It is a paid optional test that manufacturers must participate in. Solar panel testing is widely regarded as an excellent indicator of solar panel quality around the world. Inverter testing is likely to be recognized in the same way. Click here to read the entire PVEL scorecard.

The Price of a Sungrow Inverter

Because the bulk of Sungrow inverters is made in China, they are often less expensive than their European counterparts.

Pricing that is only indicative

Indicative Price Range for Sungrow Inverter Model

$3,000 to $3,250 Sungrow SH5.0RT 5kW Hybrid Inverter

$900 to $1,100 Sungrow SG5K-D-Premium 5kW Inverter

$2,000 to $2,200 Sungrow SG10KTL-MT 10kW Inverter

Keep in mind that inverter costs often range from 10% to 20% of the total system cost, therefore it is frequently worthwhile to invest in a high-quality inverter because it will have a significant impact on the efficiency and performance of your Solar Power project.

Sungrow Inverters – What Makes Them Different?

In comparison to other inverter manufacturers, the Sungrow CEC-approved Inverter line offers a variety of kinds and configurations in the normal power range. Sungrow makes string and hybrid household inverters, with Multi-MPPT available on the SG5KTL-MT, SG10KTL-MT, SG10TL-M, and SG12KTL-M string inverter types. Transformerless inverters are used in all of the CEC-approved Sungrow inverter models, which adds to their excellent efficiency.

Monitoring of Inverters

Due to the fact that all Sungrow inverter models have WIFI capability, users can remotely monitor inverter performance. The app iSolarCloud, which is accessible on both iPhone and Android, allows users to monitor performance from their phones.

Warranty on Sungrow Inverters

The majority of CEC-approved Sungrow inverters in Australia come with a 5-year manufacturer’s warranty. A 10-year manufacturer’s guarantee is included with the Sungrow Premium Inverter Range. The guarantee period begins when the inverter is installed or 6 months from the date of manufacture, whichever comes first.

With many of the growing Chinese businesses, such as Sungrow, starting to provide a standard 10-year warranty, the usual 5-year warranty is quickly becoming one of the shortest inverter warranties given in Australia. As previously said, a warranty is only worth something if the firm that provided it is still in business, and there is a way to claim it if your Solar Installer is no longer in business. Sungrow has a strong presence in Australia, including a location in North Sydney, NSW.

Inverters from Sungrow are available in Australia in a wide range of configurations.

The Clean Energy Council has authorized the majority of Sungrow’s inverters for the Small-scale Renewable Energy Scheme, Australia’s home solar rebate program.

China’s Made in China

Sungrow’s 1500V Central Inverter Model SG3125HV-MV was installed at Kristal Solar Park in Lommel, Belgium, as an example of a commercial solar project in China. The 100MW solar park is the largest in the Benelux region, with nine separate plots totaling 227 acres. Since Q4 2019, the solar park has been connected to the grid and is expected to generate 85 GWh per year.

The Sungrow SG3125HV-three-level MV’s topology design contributes to the inverter’s maximum efficiency of 99 percent and Europe efficiency of 98.7%, ensuring premium yields for the solar park. The Sungrow SG3125HV-MV features cheap transportation and installation expenses due to its 20-foot container design.
