How the GoodWe Lynx range works
Every GoodWe battery sits alongside a compatible GoodWe inverter, which decides when to charge from solar, when to discharge to the house, and whether to export. The D G2 is a modular high-voltage battery for single- or three-phase systems. The F G2 is a floor-standing tower that stacks up to 28.8 kWh and works with the EH and ET series. The U G3 is a 5 kWh wall unit that scales in parallel. All current cells are LFP, the chemistry most Australian home batteries now use.
Which GoodWe Lynx suits your home
Start with the inverter, not the battery. A GoodWe ESA, ET G2 or ET30 inverter takes the D G2; an EH or ET inverter takes the F G2; other GoodWe hybrids take the U G3.
Then size the battery to your overnight use. For example, a home using around 10 kWh between sunset and sunrise is well covered by two D G2 5.12 kWh modules (10.0 kWh usable), while a household closer to 20 kWh overnight suits a 4-module F G2 at 16.0 kWh usable. All ranges expand later, and the D G2 even allows mixing of old and new modules.

Rebates on a GoodWe battery in Perth
- Federal battery discount. From 1 May 2026 the STC rate is tiered: full value on the first 14 kWh of usable capacity, 60% from 14 to 28 kWh, and 15% from 28 to 50 kWh. The rate steps down every six months until the scheme ends in 2030.
- WA Residential Battery Scheme. For Synergy customers, the rebate scales with usable capacity from 5 to 10 kWh, with any battery of 10 kWh usable or more receiving the maximum of $1,300. You must join a VPP product with Synergy or Horizon.
- Synergy Supported Solutions List. GoodWe’s ET, ET G2, EHB, ESA, GEH and EH Plus series are listed with a DER-Storage entry, the entry the WA scheme requires.

What installation involves
Site assessment and switchboard check
We visit the property and inspect the existing solar system, the switchboard and the proposed battery space. We recommend a capacity and location, and raise any switchboard changes needed at that point.
Compatibility check
We check whether your existing inverter can work with a battery directly, or whether an inverter change is needed. You get a clear outline of the components before any installation work begins.
Choose your backup wiring
A battery only powers your home in a blackout if it is set up for backup. You choose between essential circuits only and a wider set of circuits, which affects what stays powered.
Installation day
Technicians mount the unit in a shaded, ventilated position, install isolators and route the cabling. The battery is integrated with your existing solar and inverter set-up, and every connection is tested.
Network approval
The installation is documented and connected to meet Australian standards and the requirements of Western Power. Correct isolators, testing and documentation are provided for meter approval.
Commissioning to AS/NZS 5139
Commissioning is done to the relevant standards, including AS/NZS 5139 for home batteries. We set the charge and discharge settings, connect monitoring and confirm the system stores and releases energy correctly.

Things to know before you buy
Pros
Sizing can grow with your needs. The F G2 scales from 6.4 kWh to 28.8 kWh in a single tower.
You can mix battery modules. The D G2 lets you combine different module capacities, or new and older batteries.
The D G2 has a 10-year product and performance warranty, with 70% usable energy retained.
Backup and off-grid are supported. The U G3 runs on-grid, on-grid with backup, or fully off-grid.
Things to consider
These batteries only work with specific GoodWe inverters. If you already own a non-GoodWe inverter, this range is usually not the answer.
Backup during a blackout is not automatic. On the F G2 it depends on the inverter, and on any system backup only runs on circuits wired to the backup output. Decide at quote stage.
The warranty has throughput and connectivity assumptions. The D G2 performance warranty also depends on a minimum energy throughput. On the F G2, the last 5 years of the product warranty cover hardware materials only.
GoodWe battery questions Perth homeowners ask
How safe are GoodWe batteries?
The current cells are LFP, the chemistry most home batteries now use because it is more thermally stable than older lithium types. We commission every battery to AS/NZS 5139.
What are people saying about GoodWe batteries in reviews?
Owner feedback varies, so a stable Wi-Fi connection is worth planning for.
What size battery do I need for a 6.6 kW solar system?
Battery size follows your evening and overnight consumption, not the array size. We work this out from your bills at the site visit.
Which battery is best for a home solar system?
The best battery is the one that matches your inverter, your usage and your budget. Within GoodWe, that means pairing the battery to the right inverter series.
Will solar batteries get cheaper in 2026?
The federal discount rate steps down every six months and the scheme ends in 2030. Acting sooner means a larger discount.
