How the GoodWe inverter range works
Grid-tied inverters convert your solar into AC and feed the house and the grid. Hybrids do the same job and also talk to a battery, so you can store surplus solar for the evening and keep selected circuits running when the grid drops. The SBP G2 is an AC-coupled battery inverter that retrofits a battery to a home that already has working solar.
The single-phase EHB pairs with GoodWe’s own Lynx F and Lynx F G2 batteries, and both the EHB and ET switch to backup in under 10 milliseconds.
Which GoodWe inverter suits your home
The first fork is single-phase or three-phase, set by your supply. Both the DNS G4 and MS G4 accept up to 200% PV oversizing, so a 6 kW inverter can run under a 12 kW array with the extra clipped at the peak.
Single-phase, solar only. The DNS G4 suits most 6.6 kW arrays; a larger home with a 10 kW+ array runs an MS G4.
Three-phase, solar only. The SDT G2 covers 5 to 20 kW; the SDT G3 scales up to about 30 kW of panels.
Battery now or later. For single-phase, the EHB pairs with Lynx F. For three-phase, the ET G2 is the main hybrid, with a 10-year warranty on current models. If you want solar first and a battery later on single-phase, the EH is battery-ready.

What installation involves
Site assessment
We visit the property and inspect the existing solar system, the switchboard and the space for the inverter. We talk through how the household uses power and recommend a size and location.
Switchboard check
We check the switchboard’s condition, available space and distance from the proposed location. Any upgrade needed is raised at the assessment, so it is not a surprise on installation day.
Installation day
Technicians mount the inverter in a shaded, ventilated position, install isolators and route cabling between the array, the inverter and the switchboard. Every connection is tested before commissioning begins.
Network approval
The installation is documented and connected to meet Australian standards and the requirements of Western Power, with Synergy as the energy retailer. Isolators, testing and documentation are provided for meter approval.
Commissioning
Commissioning is done to the relevant Australian standards. We configure the inverter settings, connect the monitoring and confirm the system is working correctly.
Monitoring app walkthrough
Before leaving, we show the owner how to read the monitoring app, including solar generation and household usage, and answer questions so the owner understands how the system works day to day.

Things to know before you buy
Pros
The range suits many homes. It covers single- and three-phase, grid-tied and hybrid models, so the inverter can match the house.
Hybrid models switch to backup quickly. Switchover takes under 10 milliseconds.
Current on-grid models carry a long warranty. The inverter must be registered on SEMS and manufactured after 1 July 2020.
Some models allow generous PV oversizing. The DNS G4 and MS G4 accept up to 200% PV oversizing.
Things to consider
The 10-year warranty is conditional. It applies only to inverters manufactured after 1 July 2020 and registered on SEMS after 1 January 2021, and claims must be made within one month of the failure date.
Model names don’t equal rated power on the EHB. The GW5K puts out 5000 W, the GW8.6K puts out 8600 W and the GW9.99K puts out 9990 W. Size by the actual output.
GoodWe inverter questions Perth homeowners ask
Is GoodWe a reliable brand?
GoodWe has sold inverters in Australia for a long time and offers a 10-year warranty on current on-grid models when the SEMS and manufacture-date conditions are met. Install quality and registration at commissioning make a real difference to how a claim goes.
Is GoodWe solar inverter good?
For a Perth home, GoodWe is a reasonable mainstream choice when matched to your supply type and sized properly. The install needs to be set up and registered correctly from day one.
How long do GoodWe inverters last?
The three-phase ET G2 and single-phase EHB carry a 10-year warranty; the DNS G4, MS G4 and 5-10 kW ET are listed under 5 years. A well-ventilated inverter can run beyond that, but those warranty terms are the figures to plan around.
How long has GoodWe been in Australia?
That means plenty of installers have worked on them.
Is there an app for GoodWe inverters?
Yes. GoodWe inverters report to the SEMS Portal, and SEMS registration is one of the conditions for the 10-year warranty on on-grid models.
