With a net worth of 1.5 billion dollars, Sungrow is a proud Chinese renewable energy company that started its journey
in
1997.

Back in the day, having a reliable power supply in every household was quite a struggle for many rural Chinese
people.
The renewable energy sector wasn’t as strong as it is now.

That is when Professor Cao Renxian of Hefei University decided to take on the task of researching and developing a
sustainable way to convert renewable energy resources into reliable ones.

And that is how Sungrow, the second-largest inverter manufacturer after Huawei, was born.

It was never just a business to generate profit; instead, it was a solution to the general public’s problems, which
later became a giant in the industry for all the right and good reasons.

In this blog post:

Why Sungrow Inverters Are a Smart Choice for Solar Installations?

Sungrow inverters have built a reputation in Australia for their reliability, local service support, and solid
warranty
coverage.

Besides, their hybrid systems, especially when paired with Sungrow batteries, offer an affordable and efficient home
energy storage system that is often more budget-friendly than other premium-priced systems, such as the
Tesla
Powerwall
.

Now, let’s delve into why this brand consistently ranks as a top-tier choice and why most Australian homeowners and
installers trust Sungrow Inverters.

Market Leadership & Local Presence of Sungrow Inverters

Australia’s No.1 Choice
Sungrow was crowned Australia’s top inverter and residential battery manufacturer for 2024 according to the
latest
rankings released by SunWiz, which is a leading Australian solar industry authority.
Global Dominance
As the world’s leading PV inverter supplier, Sungrow has installed over 740 GW globally as of the end of
2024. The
company operates in more than 180 countries, supported by a network of 520 service outlets and 25 European
offices.
Local Footprint
They’ve had a strong Australian presence since around 2012, with an office in North Sydney and a broad
technical
support
network.

Sungrow Inverter Review| Is Sungrow a Good Brand?

With the help of dynamic research and development, Sungrow has established itself at the forefront, so a significant
portion of its investment is dedicated to this effort.

They are capable of producing approximately 90 GW per annum. Fortunately, their inverters have been accredited by
CEC
Australia
, TUV, UL, CSA, and some other well-recognized international authorities.

But is Sungrow an actual good brand? Let’s see!

Well, the definition of a ‘good brand’ is a brand that stands true to its promises, a brand that meets its customer
expectations, and tries even to surpass that.

Hence, indeed, Sungrow is not only a good brand; it is a worthy Tier 1 inverter, which is more than just a ‘good
brand’.

They have dedicated a significant amount of their resources to R&D to improve and give the masses the confidence to
use
clean energy in the most cost-effective and efficient way possible.

Since 2012, they have been operating in Australia, and many experienced solar installers even compare their inverters
to
the popular Fronius inverters.

Fronius is a European brand that is an Australian favourite, but the catch is that they cost twice as much.

Therefore, being compared to Fronius for a fraction of the price, and being chosen over Fronius in several cases,
doesn’t Sungrow already prove its overall position? Surely it does!

Sungrow Inverters Performance

Sungrow can be an excellent choice for Australia’s diverse climate. Why?

Here are the reasons:

They can withstand high temperatures with their built-in cooling fans.
During winter months or other cloudy seasons, these inverters function well even in low-light environments.
Variable climates across VIC, NSW & QLD in Australia.

Are Sungrow Inverters Environmentally Friendly?

Yes, Sungrow is a company that genuinely cares about the environment, and their driving force is not solely profit.

Beyond just green energy generation, they ensure clean manufacturing, circular design, and a positive social impact.
Moreover, they have a carbon reduction commitment, which significantly contributes towards Australia’s target of net
zero emissions by 2050.

Aligning with the country’s renewable goals,
Sungrow is dedicating its resources to make its operations 100% green by
2028, which could be another reason why more installers are recommending Sungrow over other brands in Australia.

Operational and Manufacturing Improvements

Sungrow’s Sustainability report outlines key steps in reducing environmental impact. For example:

By using Sungrow’s inverter, the energy
consumption per unit product decreased by 6.8% in Australia.
VOC emissions per unit dropped by 46.4%, and particulate matter by 87.1%
Water use intensity per product decreased by 37.3%, while solid waste reuse/utilization improved to 60.1%.
Operations saved over 1,300 MWh via rooftop PV
installations, increasing the proportion of green electricity to 55%.

Sungrow Inverter Model Lineup in Australia 2025

There are numerous models of both residential and commercial-grade inverters available in the Australian market.

Among the many residential solar inverter models offered by Sungrow, the SG series is the most popular due to its
promising performance.

The SG series comprises string inverters, all of which are available at a very affordable price range; they also
feature
many notable benefits.

The modern SG string inverter series of Sungrow is lightweight and doesn’t have a transformer. With its dual MPPT,
Wi-Fi
connection, and an LCD display on top of the inverter, the SG series is remarkably effective at its job.

Here are some common features of the SG Residential String inverter series:

Higher yield with Max. efficiency up to 98.4%
Has a built-in LCD screen for monitoring purposes
DC/AC ratio up to 1.3
Upscale anti-corrosion rating at C5
For safe and time-efficient installation, there are push-in connectors
Online monitoring application (iSolarCloud)
Frequent firmware updates and features
Built-in surge arresters & RCD
Aluminium alloys die casting
Real-time monitoring with some of the premium models
Compact design and smart management system

However, the whole SG series can be divided roughly into three main categories, which are:

S series— Single MPPT with LCD display.
D series— Dual MPPT with LCD display.
TL-D series— Dual MPPT – parallel strings option with no display.

There is also a central inverter, mainly intended for large-scale industries. Starting from 500KW, these central
inverters can provide up to 6.8MW of power supply.

These central inverters can provide a large-scale facility with an impressive 99% efficiency rate, which should not
be
taken lightly.

Additionally, it features integrated current and voltage monitoring functions for online analysis and rapid
troubleshooting. Installation and transportation costs are significantly reduced due to its 10-foot container
design.

What Are the Advantages and Disadvantages of Sungrow Inverter?

While there are many advantages to Sungrow inverters, the disadvantages are relatively few in comparison. Here we’ve listed them all for you:

Pros of Sungrow Inverters

An average of 95% to 98% efficiency with all modules
Smartphone application to monitor the inverter
LCD with most modules for easy inspection
Fantastic warranty periods
Aussies can apply for an additional warranty period on specific residential modules.

From 1kW to 110kW, single-phase or three-phase, Sungrow hybrid inverters can fulfil any of your needs.

Cons of Sungrow Inverters

This is not necessarily a disadvantage, but the disgrace associated with being a Chinese-born brand is sometimes considered a disadvantage. Many customers tend to shift away when they learn about Sungrow’s origins.

Sungrow Inverter Monitoring System | iSolarCloud

Sungrow has its own dedicated mobile monitoring system, which can make your life significantly easier. How?

With a touch on your smartphone, you can control your inverter by installing the iSolarCloud monitoring app, which
requires a working Wi-Fi connection at home.

Previously, they had an outdated monitoring platform that hindered the user experience. What did Sungrow do about it?

They listened to customer feedback and worked on it; as a result, they now have the latest monitoring app, which can
not
only remotely regulate the inverter but also display status updates on essential criteria.

This app is simple and very easy to understand, so don’t worry; you don’t have to be a solar expert to make sense out
of
those numbers.

Moreover, for those who consider an app on even smartphones to be an extra hassle in their way of enjoying clean
power
sources, Sungrow left a tiny screen on the body of the actual inverter. This small screen will keep you updated from
time to time.

Are Sungrow Inverters Efficient? : Here’s What You Need to Know

People often ask if a Sungrow Inverter is worth it. So, let’s talk about efficiency.

Sungrow solar inverters boast an average
efficiency rate of 95% to 98% in their residential solar inverter modules.

While many inverter manufacturers barely get to 95%. Undoubtedly, Sungrow is the second-largest solar inverter
manufacturer globally.

rare combination indeed.

provide a 10-year guarantee on select models.

This has changed recently, and now most modules of Sungrow solar inverters have 10 10-year warranty. Note that only
