Sungrow Solar Inverters- Independent Review

Note: Solar Choice is not a solar installer and has no financial or other incentives to promote any product brand over another. 

Overview of Sungrow – Company History

Sungrow Power Supply Co., Ltd. was founded in China in 1997 by Cao Renxian, a professor at the Hefei University of Technology. Professor Renxian founded Sungrow after learning about the dire state of electrical availability in rural western China.

Sungrow has since grown to be one of the largest solar inverter manufacturers globally. Sungrow has manufactured over 100GW in 60 countries giving them a worldwide market share of 15%. This has contributed to the company’s valuation of $1.5 billion.

Sungrow entered the Australian market in 2012 and has stated that they have captured around 15% of the inverter market. Sungrow specialises in research and development, taking pride in being an innovation leader within the solar industry. This commitment has resulted in more than 1,600 patent applications as of June 2019.

A Brief Rundown on Solar Inverters

A solar system’s inverter is the point at which the DC electricity produced by solar panels is turned into grid-compatible AC electricity. There are four types of solar inverters, these being string inverters, hybrid inverters, microinverters, and power optimisers.

String inverters have traditionally been the standard in the solar industry. They send the power produced by solar panels to a central inverter that changes it from DC electricity to the usable AC electricity that powers homes.

Hybrid Inverters have the same characteristics as a string inverters with the additional feature of a charge controller, which is used to manage a battery system. Charge controllers can also be bought as an additional unit, but hybrid inverters provide the option of an all-in-one device.

What is PV Evolution Labs Top Performer?

PV Evolution Labs (PVEL) with support from DNV GL has been independently testing Solar Panel reliability since 2014, and for the first time in 2019 has tested solar inverters. It is a voluntary test that manufacturers have to pay to be a part of.  Solar panel testing is considered internationally as an excellent indication of solar panel quality. It’s expected that the inverter testing will have the same recognition. To read the full PVEL scorecard click here.

Sungrow Inverter Efficiency

An important aspect of getting the most value out of a solar inverter is choosing an appropriately sized inverter to optimise the solar panel system efficiency. To read about the importance of inverter sizing and system efficiency click here.

Residential inverter efficiency standards are generally 95 to 98 percent. Sungrow’s CEC Approved inverter models range in max efficiency from 97.7% to 98.6%, with the majority of the models over 98%. This places Sungrow Inverters towards the top of the residential inverter market based on efficiency.

Sungrow Inverter Costs

The majority of Sungrow inverters are manufactured in China, which means that they will generally be cheaper than European-manufactured competitors.

Indicative pricing

Sungrow Inverter ModelIndicative Price Range
Sungrow SH5.0RT 5kW Hybrid Inverter$3,000 to $3,250
Sungrow SG5K-D-Premium 5kW Inverter$900 to $1,100
Sungrow SG10KTL-MT 10kW Inverter$2,000 to $2,200

Keep in mind that inverter costs generally only run between 10-20% of your total system, so often it is worth investing in a high-quality inverter given this will have a large impact on the efficiency and performance of your Solar Power project.

Sungrow Inverters – Point of Difference

The Sungrow CEC-approved Inverter range differs from other inverter manufacturers as they offer different types and configurations in the typical power range. Sungrow manufactures both string and hybrid residential inverters, with the following string inverter models coming with Multi-MPPT; SG5KTL-MT, SG10KTL-MT, SG10KTL-M, & SG12KTL-M. All of the CEC-approved Sungrow Inverter ranges are Transformerless Inverters, which contributes to their high efficiency.

Inverter Monitoring

Sungrow provides users with the ability to remotely monitor inverter performance, as all inverter models come with WIFI capabilities. Users can monitor performance from their phone through the app iSolarCloud, which is available on both iPhone and android.

Sungrow Inverter Warranty

In Australia, the majority of CEC-approved Sungrow inverters come with a standard 5 year manufacturer’s warranty. The Sungrow Premium Inverter Range comes with a 10-year manufacturer’s warranty. The warranty period commences on the date the inverter is installed, or 6 months after the date of production, whichever occurs first.

The standard 5 year warranty is rapidly becoming one of the shortest inverter warranties offered in Australia with many of the growing Chinese companies like Sungrow starting to offer a standard 10-year warranty. As we’ve discussed previously, a warranty is only worth something if the company providing it is still around and there is an accessible route to claiming it if your Solar Installer is no longer around. Sungrow is well established in Australia with an office in North Sydney, NSW.

A Full Range of Sungrow Inverters Available in Australia 

There are 39 of Sungrow Inverters (under the name of Sungrow Power Supply Co Ltd) approved by the Clean Energy Council for the Small-scale Renewable Energy Scheme, which is Australia’s home solar rebate program. The majority of the listed inverters are available in Australia.

Sungrow offers string, central, and turnkey inverters to accommodate various solar projects. Their string inverters, ranging from 2kW to 352kW, are well-suited for residential and commercial installations. Sungrow’s central and turnkey inverter series target larger commercial and utility-scale solar projects. This review will primarily focus on Sungrow’s string inverters, which are commonly found in Australian solar markets.

Single phase Inverters 

Sungrow offer single phase inverters with output capacity of 2kW to 8kW. For the commonly used 5kW inverter size, Sungrow offer the SG5.0RS and the SG5.0RS-ADA. Seemingly similar in most characteristics the SG5.0RS-ADA is almost twice the size and weight.

The extra size seems to be invested in the inclusion of an additional maximum power point tracker (MPPT) allowing solar designers to includes solar panels on a 3rd direction on the roof.

Both inverters have low voltage requirement to start up meaning they will turn on slightly earlier in the morning than other inverters on the market and stay running slightly later in the evening.

Residential Three Phase Inverters

Sungrow’s RT series is their main 3-phase solution catering to residential solar systems and small businesses with an output capacity ranging from 5kW to 20kW.

The inverters reach an impressive maximum efficiency of up to 98.5% for their 20kW inverter. 

Unlike the RS series, the RT series does not include a built-in screen or even LEDs on the inverter body so customers will have to rely solely on the monitoring app to check performance. 

One limitation for users with more complicated solar panel layouts on the roof, is that the inverters only come with 2 MPPTs. Many other 3 phase inverter options have 3 or 4 MPPTs at similar inverter capacities.

CX Series (Commercial Solar Inverters)

One place where Sungrows excels for value and quality is in their commercial solar inverter range.

The Sungrow CX series, coming in 30kW, 50kW and 110kW sizes, is very popular amongst commercial solar installers due to their versatility, performance and attractive price point. 

These inverters range from 3 MPPTs and a max efficiency of 98.6% on the 30kW model to 9 MPPTs and 98.7% max efficiency on their 110kW model.


These inverters still lack a decent display screen on the physical device and are supported by an online web portal and app.

Inverter works great and getting maximum feed in tariff. Apparently, there is a limit of 5kw on the feed in. We have 2 phases (unusual arrangement) so we are getting a good feed in rate of 5kW per phase. The Monitoring app can't handle dual phase but I have a work around using the retailer's website. (The app can't show the amount consumed if you have 2 phases, it can handle 1 or 3 but not 2).

All fine so far but would have loved to also have what I now know is the add on to measure usage against generation. While we can do this retrospectively (next day) with our power company’s app, I’d love to see the data in real time. We didn’t know this wasn’t possible until after the install.

I really like the Sungrow app that keeps track of how much is being generated and shows me graphs for each day, week, month, etc. It also stores all the data even when my internet disconnects, and the app is updated retrospectively once I connect again. The 5kW inverter seems to hit a maximum of about 4.6kW-4.9kW during the middle hours of the day.

Good brand. I had a 8kw inverter installed.

Research suggestions it’s a middle of the road inverter which I was after. Connects to an app to show in real time how the system is performing.

Love the app you can see in real time how much power you are using and the state of your batteries . We can use up to 10 KW directly from the panels in full sun. Maintains the system well and has a great warranty

Minor annoyance: you lose access to the inverter's wi-fi dongle when the sun goes down, so you can't check live power consumption at night. The inverter failed after 26 months. Sungrow say there was an overvoltage alert after power was restored following an outage but it was about 5 days afterwards it started throwing internal module failure alerts. Raised a warranty claim with Sungrow on 28/10/22 and the replacement inverter arrived on 3/11/22.

The first inverter failed and after 25 days was replaced. The second failed to work as designed. Over time we learnt of the cabling issues, the wiring issues and the very likely possibility of programming issues. We also learnt that the inverter and battery pairing as wired would not provide WOHEPS nor would the pairing of the BYD battery and Inverter do so. In early 2021 Sungrow twice offered (Stag) to replace the Sungrow inverter. Stag did not take up those offers. Later on Sungrow offered (us) to replace the inverter. We declined as they could not confirm that the third inverter would not have the same issues as the first two. In fact an email from Sungrow advises that it would perform in a manner to the previous units. BYD Sydney and then China confirmed that the battery inverter pairing as was, could never in fact provide WOHEPS. • How is it that neither Sungrow or Stag appeared to know of this or when informed of it, failed to act in a positive manner. 10kW Sungrow Hybrid Inverter was replaced twice, fails to pair well with the BYD battery for Whole of House Emergency power supply, the reason the system was initially purchased. Sector specialists and a CEC sourced expert review found that the system as wired would never produce a whole of house EPS. • Further, only one circuit was connected for EPS. • Several specialists advised that the Sungrow / BYD pairing would not / could not provide WOHEPS. • Further, BYD Sydney and then BYD China confirmed that the BYD 11.2 kW battery and the 10kW Sungrow Hybrid Inverter when paired together would not in fact produce WOHEPS. • How is it that neither Sungrow or Stag appeared to know of this or when informed of it, failed to act in a positive manner.

Not much to comment on, we can monitor generation of energy on an app, unfortunately that loses connection to our network occasionally but I believe that has more to do with our network (which at the moment is temperamental) then with the inverter. The app provides lots of info by the way which is (in a nerdy way) quite interesting.
