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 to the grid.
The Lynx range splits into four families: the Lynx D G2 is a modular high-voltage battery that suits both single-phase and three-phase systems and pairs with the ESA (single or three phase), ET G2 and ET30 inverters; the Lynx F G2 is a floor-standing tower that stacks modules up to 28.8 kWh and works with the EH and ET series on single or three phase; the Lynx U G3 is a 5 kWh wall unit that scales in parallel up to 150 kWh for larger systems; and the Lynx Home U is the earlier wall-mounted range that scales from 5.4 to 32.4 kWh.
All current Lynx cells are LFP (lithium iron phosphate), which is the chemistry most Australian home batteries now use.

Which GoodWe Lynx suits your home
Start with the inverter, not the battery. If you have (or are quoting) a GoodWe ESA, ET G2 or ET30 inverter, the Lynx D G2 is the match. If it is an EH or ET inverter, choose the Lynx F G2. For other GoodWe hybrids, the Lynx U G3 is the compatible option. Single or three phase matters for the inverter more than for the battery: the Lynx D G2 works with both single-phase and three-phase systems, and the Lynx F G2 also suits both.
Then size the battery to your overnight use. For example, a home that uses around 10 kWh between sunset and sunrise is well covered by two Lynx D G2 5.12 kWh modules (10.0 kWh usable) or a 2-module Lynx F G2 tower at 6.4 kWh usable with some grid support. A larger household using closer to 20 kWh overnight is better served by a 4-module Lynx F G2 at 16.0 kWh usable or a 5-module stack at 19.2 kWh usable.
All of the Lynx ranges can be expanded later: the Lynx D G2 supports up to 12 units in parallel and allows mixing of old and new modules, and the Lynx F G2 scales to 8 towers in parallel.
Rebates also shape the choice. The federal discount is tiered from 1 May 2026, with the full rate on the first 14 kWh and reduced rates above that. The WA scheme caps at any battery of 10 kWh usable or more, so a 10.8 kWh Lynx Home U configuration or a 2-module 10.0 kWh Lynx D G2 (two 5.12 kWh modules at 5.0 kWh usable each) both reach the maximum.

Rebates on a GoodWe battery in Perth
- Federal battery discount. Applied up front through STCs on batteries with 5 to 100 kWh of nominal capacity. From 1 May 2026 it 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 declines every six months and the program ends on 31 Dec 2030. Your install date, not your contract date, sets the rate.
- 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 Virtual Power Plant (VPP) product with Synergy or Horizon. The scheme is expected to run until 2027.
- Synergy Supported Solutions List. The battery must be on this list to receive the WA rebate. GoodWe’s ET, ET G2, EHB, ESA, GEH and EH Plus series are all listed with a DER-Storage entry, which is the entry the WA scheme relies on. We confirm your exact model before you sign.
What installation involves
We start with a site visit. We inspect your existing solar system and switchboard, check whether your inverter can run a battery directly or whether a new or additional inverter is needed, and agree where the Lynx will go. Position matters: a shaded, ventilated spot keeps the battery within its operating range and protects the warranty. Before install day we lodge the network application with Western Power and the Synergy connection paperwork, and we confirm your model is on the Supported Solutions List for the WA rebate.
On install day, we mount the unit, fit the isolators and route the cabling between the array, inverter, battery and switchboard. If you have chosen backup, we wire the circuits you want to keep running during an outage: a battery only supplies power in a blackout if it has been set up that way. We commission to AS/NZS 5139, configure the charge and discharge settings, and then walk you through the monitoring app so you can read battery charge, solar generation and household usage before we leave.
One practical tip: keep the Wi-Fi dongle connected, as remote monitoring is how we and the service team diagnose any issue quickly.
Things to know before you buy
Pros
Flexible sizing: the Lynx F G2 scales from 6.4 kWh up to 28.8 kWh in a single tower, and up to 8 towers run in parallel for 230 kWh.
Mixing is allowed: the Lynx D G2 lets you combine different module capacities, or new and older batteries, when you expand.
10-year product and performance warranty on the Lynx D G2, with 70% usable energy retained at the end of that period.
Backup and off-grid support on the Lynx U G3, which runs on-grid, on-grid with backup, or fully off-grid.
Things to consider
Lynx batteries only work with specific GoodWe inverters. The Lynx D G2 pairs with the ESA, ET G2 and ET30 series; the Lynx F G2 with the EH and ET series; the Lynx U G3 with GoodWe hybrids. If you already own a non-GoodWe inverter, a Lynx is usually not the answer. We confirm the match before you commit.
Backup during a blackout is not automatic. On the Lynx F G2 the backup capability depends on the inverter, and on any system backup only runs on circuits that have been wired to the backup output. Decide at quote stage whether you want essential circuits only (fridge, lights, a few power points) or a larger load, because that choice drives the inverter and the wiring.
The warranty has throughput and connectivity assumptions. The Lynx D G2 warranty assumes one full cycle per day and guarantees a minimum throughput of 3.0 MWh per kWh of usable capacity. For the Lynx F G2, the last 5 years of the product warranty cover hardware materials only. Claims are made via the installer or distributor, so install quality and after-sales support matter.
Owner-reported service issues. The most commonly reported owner complaints are the Wi-Fi dongle dropping its internet connection and slow responses from the service desk. Keep the system online so faults can be diagnosed quickly, and raise any claim through us as your installer rather than directly.
GoodWe battery questions Perth homeowners ask
How safe are GoodWe batteries?
The current Lynx cells are lithium iron phosphate (LFP), which is the chemistry most home batteries now use because it is more thermally stable than older lithium types. Safe installation is also part of the picture: positioning, ventilation and switchboard protection all matter, which is why we commission every battery to AS/NZS 5139.
What are people saying about GoodWe batteries in reviews?
Independent reviewers generally position GoodWe as one of the cheaper battery brands per warranted kWh and credit it with a long presence in Australia. Owner feedback is more mixed: the backup behaviour and automatic reboot after voltage dips are commonly praised, while the most reported issues are the Wi-Fi dongle dropping its connection and slow responses from the service desk. Reviewers also note that the earlier Lynx models underperformed and recommend sticking with the current generation.
What size battery do I need for a 6.6 kW solar system?
There is no single answer: 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 the GoodWe range, the Lynx D G2 pairs with the ESA, ET G2 and ET30 inverters, the Lynx F G2 pairs with the EH and ET series, and the Lynx U G3 works with GoodWe hybrid inverters. We confirm the right combination at quote stage, including whether you need a single-phase or three-phase setup.
Will solar batteries get cheaper in 2026?
The upfront cost to a homeowner is already dropping thanks to the federal battery discount that started in 2025, which is applied up front through STCs. From 1 May 2026 the subsidy is tiered: the full rate applies to the first 14 kWh, 60% from 14 to 28 kWh, and 15% from 28 to 50 kWh. The rate also steps down every six months and the program ends on 31 Dec 2030, so acting sooner means a larger discount.
