Sungrow Inverters – Point of Difference

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
The app makes it very easy to see when it best to use electricity in real life time.
happy with the app, could be a bit more friendly in certain parts (all info is there though) very good reports on the inverter, lots of research to see what was available, good value
Happy with this brand . The boys showed us how to use the app, it’s great we use it all the time.
very easy to use. the sungrow app is able to monitor my fronious inverters production aswell. overall a nice clean instal.
The app works well, showing details stats on usage (showing system to grid, system to house, and grid to house values). It also has aggregate stats for the day/week/month/year which will be useful to track performance over time.
Happy with the app. The inverter is Sungrow a good midrange system.

No because I don't know how to get the app working
I am very happy with the brand of inverter and its functionality and the app service that interacts with my smartphone. Look good and is very neat and tidy on the wall.
Once setup the app is really easy to view the inputs & outputs from the system to see where the power is going. The unit itself is small & has a quickview panel on it to see the generation & battery % without needing to log on the app.
As with the panels, so far so good. All appear to be working well.
Talks reliably to the same brand battery

Still not to AS standard and deemed not safe to operate...Contractor has Liquidated and moved to NSW beware
I went with Sungrow after good experience on another site. It has performed faultlessly. I especially like the software which has soom for expansion and is compatible with other systems.
Love the app and ability to monitor energy consumption and production in real time.
I am happy with the Sungrow Inverter and the current output (maximum). I chose this brand because it is one of the more reputable brands on the market. The monitoring portal is also easy to use and presents the essential information in an easy to understand format.
Had a connection issue at start but working well now, with the help from Martin.
Great app to see what's happening in real time.
Happy with the system so far. We just got installed
Very happy with the app on my phone for easy monitoring of system performance,easy to use & has everything you need.
I’m very happy with the app which allows me to monitor the performance of the panels and inverter in real time. My son also has this brand installed and is very happy with it.
