GoodWe has been selling solar inverters in Australia for years, and SunWiz ranked it the third biggest behind-the-meter inverter brand here in 2025. Its batteries are sold under the Lynx name, and the one you will see on most quotes is the Lynx Home F G2. GoodWe has also launched the ESA, an all-in-one cabinet with the inverter and battery together. This review covers both, because which one you should get depends a lot on your home.
The short verdict
GoodWe is a good-value, low-drama choice, particularly if you already have a GoodWe inverter or want a battery you can size precisely. The Lynx F G2's 3.2kWh steps let you buy close to what you need. The ESA is the more interesting product for new single-phase homes because it includes 63A whole-home backup without a separate gateway.
It suits you if
- You already have a compatible GoodWe hybrid inverter and want to add storage.
- You want to size a battery precisely rather than jump in big 5 to 13.5kWh blocks.
- You want whole-home backup on a single-phase home without paying for a separate gateway (ESA).
- You want a mainstream brand at a lower price than the premium names.
Skip it if
- VPP income is central to your plan. GoodWe's VPP support is narrower than Tesla, Sungrow or Sigenergy.
- You want to keep a non-GoodWe hybrid inverter. Lynx batteries are built for GoodWe inverters.
- The battery will sit somewhere exposed. The Lynx F G2 is rated IP55, lower than many rivals, so placement matters.
The GoodWe home battery range in Australia
| Spec | Lynx Home F G2 | ESA all-in-one |
|---|---|---|
| Usable capacity per module | 3.2 kWh | 5 kWh or 8 kWh (can be mixed) |
| Stacking | 2 to 9 modules per tower, 6.4 to 28.8 kWh. Up to 8 towers in parallel. | Up to 6 modules per stack (about 48 kWh), up to 6 stacks in parallel |
| Chemistry | LFP | LFP |
| Power | Set by the inverter. Battery nominal rating from 4.48 kW (6.4 kWh) to 20.16 kW (28.8 kWh), for example 8.96 kW at 12.8 kWh. | Built-in single-phase inverter from 3 to 10 kW, battery discharge up to 11 kW on the largest model |
| Coupling | DC-coupled with a GoodWe hybrid (EH or ET family), or AC-coupled with a GoodWe battery inverter (BH or BT) next to existing solar | All-in-one: solar, battery and inverter in one cabinet (single-phase) |
| Blackout backup | Via the hybrid inverter's backup output, wired by your installer | 63A whole-home backup, no gateway needed, under 4 ms switchover |
| Warranty | 10-year performance warranty: at least 70% of usable energy, or a minimum energy throughput, whichever comes first. Check the product (hardware) term on the current Australian document. | |
| Rating and mounting | IP55, indoor or outdoor, floor standing | IP66, indoor or outdoor, floor stacked or wall mounted |
GoodWe also sells the low-voltage Lynx Home U (4.8kWh usable per module, up to 28.8kWh, IP65), which pairs with GoodWe's low-voltage ES and EM inverters. It mainly matters if you already own one of those inverters. One quirk worth knowing on the F G2: the smallest 6.4kWh tower cannot start GoodWe's larger three-phase ET inverters (15 to 30kW), so big three-phase systems need at least three modules.

What we like
- Precise sizing. The Lynx F G2's 3.2kWh modules mean 9.6kWh, 12.8kWh or 16kWh are all options. You pay for what you use, and you can keep a stack at 12.8kWh to stay under the 14kWh point where the federal discount rate drops.
- ESA backup included. 63A whole-home backup with no gateway is a genuine point of difference. With several rivals, a proper backup setup is an extra box and extra labour.
- Established inverter brand. GoodWe inverters have been common on Australian roofs for years, so installers know them well.
- Good value. GoodWe sits at the lower end of after-rebate pricing for a mainstream stackable LFP battery.
- Three-phase friendly. The Lynx F G2 with a GoodWe ET hybrid is a straightforward three-phase setup.
What to watch
- Inverter lock-in. The Lynx is designed for GoodWe inverters. That is fine if you already have one, less so if you do not.
- IP55 on the Lynx F G2. That rating covers indoor and outdoor use, but it is a step below the IP65 or IP66 many rivals list. A sheltered wall or garage is the better spot.
- Narrower VPP choice. Covered below.
- Warranty paperwork. GoodWe's global Lynx F warranty splits cover into 5 years on the electronics and enclosure and 10 years on performance. Australian sellers generally quote 10 years for both, so ask your installer for the current Australian document and keep a copy.
- The 2025 hybrid inverter recall. Covered below. It affected some GoodWe EHB inverters, not the batteries.
Real-world considerations
Inverter compatibility
If you already have a GoodWe hybrid inverter, adding a Lynx F G2 is usually the cheapest and simplest battery upgrade available to you. If you have another brand of solar inverter, you have two options: keep it and add a GoodWe battery inverter alongside (AC coupling), or replace it with a GoodWe hybrid, or an ESA on a single-phase home. Which one is cheaper depends on the age of your current inverter. Our battery and inverter compatibility guide walks through it.
Backup and blackouts
With a Lynx battery, backup comes from the GoodWe hybrid inverter's backup output. Your installer decides which circuits connect to it, and the inverter's size limits how much can run at once. The ESA is different: it is designed to back up the whole home up to 63A with no extra gateway, which suits homes that lose power often or run essential equipment. Either way, ask for the backup design to be written into the quote.
App and monitoring
Homeowners use GoodWe's SEMS+ app; installers set systems up with a separate app. SEMS+ shows solar, battery and grid flows and handles firmware updates, and GoodWe asks owners to keep it updated (version 2.2.0 or later is needed for the Amber integration). Keep the system online so remote firmware fixes, like the 2025 recall update, reach you.
VPP compatibility
This is GoodWe's weakest area. Amber began a limited release of its SmartShift integration with GoodWe in January 2026, starting with the ESA and EHB inverters and onboarding people from a waitlist. Independent trackers also list programs such as Origin Loop and EnergyAustralia's BatteryEase, but their lists do not match, so confirm with the VPP before you buy if VPP payments are part of your payback. In NSW, joining an approved VPP is what unlocks the separate state incentive, so this matters there. Our VPP comparison has the details.
The 2025 EHB inverter recall
In September 2025 the ACCC published a recall for certain GoodWe EHB and GE-branded GEH single-phase hybrid inverters sold between May 2021 and September 2025. If switched to bypass while running in backup mode, they could export power to the grid through the bypass switch, a shock risk for anyone working on the lines. The fix is a firmware update, pushed remotely to online systems, with a technician visit for offline ones, and new installs are updated before commissioning. Lynx batteries were not part of the recall, but if you are buying a second-hand or recently installed EHB system, check the firmware has been done.
What it costs after the federal discount
After the federal Cheaper Home Batteries discount, a GoodWe battery typically costs around $6,000 to $9,500 fully installed. That is at the value end of the market. Our battery cost guide puts a generic 10kWh battery at $7,000 to $10,000 after the discount, and GoodWe often comes in at or below the lower half of that for similar sizes.
| Setup | Usable capacity | Indicative installed (after federal discount) |
|---|---|---|
| Lynx F G2, 3 modules | 9.6 kWh | From about $6,000 |
| Lynx F G2, 4 modules | 12.8 kWh | About $6,900 to $7,900 |
| ESA, two 8 kWh modules | 16 kWh | About $8,000, up to $9,500 with a larger inverter or tricky install |
These assume a compatible GoodWe inverter is part of the job. If you already own one, a battery-only add-on can come in lower. The federal discount is worth roughly $240 to $270 per usable kWh at current certificate prices, at the full rate up to 14kWh and a reduced rate above that. Your state may offer a separate incentive, such as a VPP connection payment in NSW or a low-interest loan in the ACT. We always show the federal discount and any state incentive as two separate numbers, never one merged figure. See battery rebates by state, use the savings calculator, and check our battery sizing guide before settling on a size.
How it compares
| Battery | Best at | Watch out for | Indicative after federal discount |
|---|---|---|---|
| GoodWe Lynx / ESA | Precise sizing, ESA whole-home backup, value | Narrower VPP list, IP55 on Lynx F G2 | $6,000 to $9,500 |
| Sungrow | Value, long track record, broader VPP support | Needs a Sungrow hybrid inverter | $6,000 to $9,000 |
| FoxESS | Big stacks at a competitive price per kWh | App, installer-led support | $7,500 to $11,000 |
| Sigenergy SigenStor | All-in-one stack, EV charging, app | Premium price, gateway for backup | $8,000 to $13,500 |
Price ranges are each brand's typical installed size, from our brand pages, so they are a guide to budget rather than a straight per-kWh comparison.
Against Sungrow: the two are close on price. Sungrow usually has the edge on VPP support; GoodWe has the edge on fine-grained sizing and, with the ESA, built-in whole-home backup. See our Sungrow review.
Against FoxESS: FoxESS offers bigger stacks and competitive pricing per kWh at larger sizes. GoodWe is the more established inverter brand. Read our FoxESS review.
Against Sigenergy: the ESA and the SigenStor are both all-in-one, stackable systems. The SigenStor has the better app and an EV charger option, but backup needs its gateway. The ESA includes 63A backup and usually costs less. Read our Sigenergy SigenStor review, and see the Alpha ESS SMILE and BYD Battery-Box reviews for more options.
Our take
GoodWe does not have the buzz of some newer brands, and that is partly the appeal. If you already have a GoodWe inverter, a Lynx F G2 is often the obvious, cost-effective upgrade. On a new single-phase install, the ESA's included whole-home backup makes it one of the better value all-in-one systems around. Just go in knowing VPP options are limited for now, and make sure you have the Australian warranty terms in writing.
