A Full Range of Sungrow Inverters Available in Australia
RS Series – Residential Single Phase Inverters
RT Series – 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.
SH Series – Hybrid Solar Inverters
All of Sungrow’s residential single phase and three phase inverters come in a hybrid option. A hybrid inverter has the ability to convert power from AC/DC as well as regulate solar power so that it can charge a battery. This option is designed for customers adding a battery, or hoping to keep their options open to add a battery in the future.
Sungrow manufacture their own battery solution which can be seamlessly connected with their hybrid inverters.
The amount of solar panels connected to these inverters can be significantly oversized to ensure the battery is fully utilised. For example the 5kW option (SH5.0RS) allows owners to connect up to 12kW of solar panel capacity.
For their 5kW inverter there is roughly a $1,000 premium to add in the hybrid functionality from their regular 5kW inverter.
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.

Example of a Sungrow Commercial Solar Project
Sungrow’s 1500V Central Inverter Model SG3125HV-MV were installed at Kristal Solar Park, located in Lommel, Belgium. The 100MW solar park has nine different plots covering 227 Acres and is the largest in the Benelux region. The solar park has been grid-connected since Q4 2019 and is expected to generate 85 GWh annually.
The three-level topology design of the Sungrow SG3125HV-MV contributes to the inverter’s maximum efficiency of 99% and Europe efficiency of 98.7%, guaranteeing premium yields for the solar park. Due to the 20-foot container design, the Sungrow SG3125HV-MV has low transportation and installation costs.
Since 2008 our knowledge and sophisticated software has allowed over 300,000 Australian households and businesses to make a well-informed choice on their solar & battery installer.

Reviews from Australians who have installed Sungrow Inverters
Inverter has the ability to keep up with our demands, day and night
Review left 2 years after system installed
The app doesn’t work - I have to use my catch inverter to monitor instead.
excellent and well coordinated with isolarcloud
Review left 2 years after system installed
The app works well and enables real time tracking of output and power use including reviewing of historical data.
Great App, Very Helpful WRT problem solving and fault finding
Happy with the app and went with the Hybrid so we can add a battery down the track.
The monitoring app is so easy and simple to use we are very happy with this operating system
System works as it should, still to early to tell.
The iSolarCloud app provides clear, real-time insights, showing that I’ve drastically reduced my grid energy usage—down to just a fraction of what I used before.

The app on my PC and mobile is excellent, gives me all i require as an end user.
I am happy with Sunsmart being able to inform me if something is not correct with my system. The system wasn't connected to the internet, and they informed me of this which I wouldn't have known about. The system and Inverter were the products being used by Sunsmart and when questioned I was given an answer
seems to do what its supposed to do. Easy to monitor for output etc.
Excellent quality and value for a mid range price
Very happy with invertor. Aztech salesman sized the invertor perfectly for my requirements. I think the Sungrow software is maybe not as good as some but still provides all the information that you may require. Early days yet to give a more concise comment.
The iSolarCloud software is okay, it takes a bit of time to work through how I wanted it set up, but Google & YouTube help
Review left 2 years after system installed
This is not the inverter I wanted however because of ecg stuff up it is what I got. The system was set up to take a battery in a certain area which ecg advised would be acceptable, however it can not be placed where they said it could. They also charged us extra for wiring which cannot be used. Deposit paid 22/9/23 on basis it would be completed in October and job was not completed until 25/1/24
This ISolarCloud app is very easy to use and understand
Very happy with the performance and app. Only problem is (like any new toy) im checking it every few hours.
