About GoodWe
What is the GoodWe ESA?
The GoodWe ESA is an all-in-one home battery. A GoodWe hybrid inverter sits on top of a stack of lithium iron phosphate (LFP) battery modules, and the units join through plug-in connectors built into each case. The single-phase range (EHA models) has six inverter sizes from 3 kW to 10 kW. The three-phase range (ETA models) has nine sizes from 5 kW to 30 kW.
Storage comes from battery modules rated at 5.12, 6.0, 8.32 or 9.0 kWh. One system takes up to 12 modules, from 5 kWh to 108 kWh, and different module sizes can be mixed. The ESA is made by GoodWe Technologies, a company founded in 2010 and based in Suzhou, China. GoodWe Australia, in Rowville, Victoria, is the Australian importer.
The stack can stand on a floor base against a wall, with up to six modules in one column. Smaller stacks of two or three modules can hang on the wall instead. Each module weighs 57.5 to 79 kg, so stacks of more than three need lifting equipment. A smart meter with a current transformer (CT) at the switchboard tells the system what the home imports and exports, and the installer commissions everything in GoodWe's SolarGo app.

Warranty & compliance
- The ESA battery modules we quote (GW8.3-BAT-D-G20 and GW9.0-BAT-D-G20) are covered by GoodWe’s Limited Warranty for the Lynx D G2 Series battery system (Australia and New Zealand), which has two parts. The ESA inverter carries GoodWe’s 10-year limited inverter warranty.
- A 10-year product warranty covers the battery hardware , the electronics and the enclosure , against defects. A 10-year performance warranty guarantees that the battery retains at least 70% of its usable energy, or until throughput reaches 3 MWh of DC energy for every kWh of usable capacity, whichever comes first.
- GoodWe’s warranty requires the battery to be kept out of direct sunlight and states it is not suitable for life-sustaining medical devices. These are the manufacturer’s terms; your guarantees under the Australian Consumer Law apply in addition. Sunbridge registers the warranty on your behalf as part of the installation.
Rebate guidance
- Battery incentives change over time and depend on the exact battery model, the installation and your household. The federal Cheaper Home Batteries Program requires the battery to be on the Clean Energy Council approved list, and listing alone does not make a household eligible.
- Where an incentive applies, your Sunbridge quote shows it as a separate deduction, subject to eligibility at the time of installation. Your quote lists the exact battery model so you can check it against the approved list. See our battery rebate guidance for how the current programs work.

What size GoodWe battery do I need?
Start with the energy your home uses between sunset and sunrise. Your retailer bill, smart meter data or solar app shows it in kWh. Choose a battery whose usable capacity covers that, plus any growth you expect from an EV or electric hot water. The site inspection confirms the size before you commit.
Every ESA is a stack of modules rated at 5.12, 6.0, 8.32 or 9.0 kWh, and our packages use the two larger sizes. Our 18, 27, 36, 45 and 54 kWh packages are two, three, four, five and six 9.0 kWh modules. Our 33.28, 41.6 and 49.92 kWh packages are four, five and six 8.32 kWh modules. Usable capacity is slightly lower than rated (GoodWe's datasheet gives 8.0 kWh usable for an 8.32 kWh module), and our price table shows the usable figure for each package. One column holds up to six modules. Beyond that, GoodWe's expansion kit splits the battery into up to three groups, with a ceiling of 12 modules or 108 kWh per system. Modules can be added later, but wall-mounted stacks are limited to two or three modules, and the module mix also sets how much power the battery can deliver at once.

Can I add a GoodWe battery to my existing solar?
Usually, yes, and there are two ways to do it. Your existing panels can be rewired to the ESA's own solar inputs, which retires the old inverter, as long as the panel strings fit within the ESA's voltage and current limits. Or the old inverter can stay and connect on the AC side, which GoodWe supports for its own and third-party inverters if the old inverter's rating is no larger than the ESA's. A site inspection confirms which option suits your panels, inverter and switchboard.
- Solar inputs: the single-phase hybrid accepts up to 600 V DC, with 2 solar inputs on the 3 to 6 kW models and 4 on the 8 and 10 kW models, 20 A per input, and panels up to 200% of the inverter rating. The three-phase hybrid accepts up to 1,000 V DC, with 3 inputs on the 5 to 8 kW models and 4 on the 10 kW and larger models. Our quotes include an optional line for removing the old inverter.
- Keeping the old inverter (AC coupling): it connects on the grid side of the ESA. GoodWe recommends its own inverters but supports third-party ones, and the old inverter's rated output must be less than or equal to the ESA inverter's rated output. GoodWe also makes AC-coupled ESA versions with no solar inputs (BHA single-phase and BTA three-phase models).
- Metering: every ESA works from a smart meter and CT at the main switchboard. Our single-phase packages list a GoodWe GMK110 meter and our three-phase packages generally list a GMK330. When an old inverter stays, GoodWe's manual calls for a second meter so the app can show that inverter's output and the true household load.
- Export limits: if the old inverter also has to be export-limited, GoodWe says it needs its own meter or CT, and each inverter's limit is set separately.
- Phase: EHA models connect to a single-phase supply (220 to 240 V) and ETA models to a three-phase supply (230/400 V). The ESA has to match the home's supply.

GoodWe ESA pros and cons
What we tell customers before they choose GoodWe.
Pros
- One integrated system: the inverter and battery stack join with plug-in connectors, and GoodWe covers the ESA inverter with a 10-year limited warranty and the battery modules with a 10-year product and performance warranty.
- Wide size range: six single-phase inverter sizes (3 to 10 kW), nine three-phase sizes (5 to 30 kW) and four module sizes, from 5 kWh up to 108 kWh with 12 modules.
- Room for more solar: the hybrid models accept panels up to 200% of the inverter rating, for example 20 kW on the 10 kW single-phase model and 60 kW on the 30 kW three-phase model.
- Backup-ready design: a dedicated backup port, switchover in under 4 ms and an internal grid bypass of up to 63 A (80 A on the 25 and 30 kW three-phase models) allow whole-home backup designs with the right backup configuration.
- Built for outdoor sites: the inverter and modules are rated IP66, the inverter operates from -35 °C to +60 °C (the single-phase model derates above 40 °C), and the G20 modules have built-in heating and aerosol fire extinguishing.
- Quiet rating: GoodWe rates the single-phase inverter at 30 dB or less on the 3 to 6 kW models and 35 dB or less on the 8 and 10 kW models, and the battery modules at 29 dB or less.
Cons and things to check
- Newer product line: GoodWe Australia announced the ESA in October 2025, and its documents have changed quickly. The July 2025 installation manual capped a single-phase battery cluster at 48 kWh with two module sizes, while current datasheets list four module sizes and 108 kWh. Check that your quote uses current models and firmware.
- Power differs by module: the 5.12 and 8.32 kWh modules are rated at 5 kW and 8 kW each, but the 6.0 and 9.0 kWh modules at 3 kW and 4.5 kW each. GoodWe's 1C charge and discharge headline applies to the first pair, so check combined module power, not just kWh.
- Heavy and needs space: modules are 800 mm wide and weigh 57.5 to 79 kg each. Wall mounting is limited to two or three modules per stack, so larger systems need floor space, and GoodWe's warranty requires the battery to be kept out of direct sunlight.
- Backup has limits: in a blackout the ESA can only supply its off-grid rating, for example 10 kVA on the 10 kW single-phase model (20 kVA for 10 seconds). The higher bypass rating only applies while grid power is available. GoodWe's warranty also states the battery is not suitable for life-sustaining medical devices.
- Mixing caveats: GoodWe's manuals say battery heating is unavailable when module types are mixed, and mixing or split expansion needs BMS and DC-DC firmware V06 or later.

FAQ
Frequently asked questions
It is a current LFP all-in-one system from GoodWe, a listed inverter maker founded in 2010, and GoodWe Australia describes it as Clean Energy Council approved. The ESA inverter has a 10-year GoodWe warranty and the battery modules a 10-year product and performance warranty. It is a newer product line, so whether it suits your home depends on your supply phase, roof, switchboard and backup needs.
GoodWe Technologies Co., Ltd. makes them. The company was founded in 2010, is based in Suzhou, China, and has been listed on the Shanghai Stock Exchange (stock code 688390) since 2020. GoodWe Australia Pty Ltd, in Rowville, Victoria, is the Australian importer.
GoodWe rates the 5.12 and 8.32 kWh modules for at least 8,000 cycles and the 6.0 and 9.0 kWh modules for at least 10,000, based on laboratory testing. The battery warranty runs 10 years and covers 70% of usable energy, or until throughput reaches 3.0 MWh per usable kWh, whichever comes first. The ESA inverter carries a 10-year limited warranty.
It can, with the right backup configuration. The ESA has a dedicated backup port, and GoodWe states switchover in under 4 ms on the hybrid models. During an outage, output is limited to the inverter's off-grid rating, for example 10 kVA on the 10 kW single-phase model. Which circuits are covered is decided at design and installation.
Each battery module measures 800 x 326 x 270 mm (W x H x D) and weighs 57.5 to 79 kg depending on its size. The single-phase inverter is 800 x 300 x 270 mm and 24 to 26 kg, and the three-phase inverter is 800 x 340 x 270 mm and 34 to 38 kg. Total height depends on how many modules are in the stack, plus the floor base.
Yes. GoodWe's time-of-use (TOU) mode can charge the battery from the grid in a low-tariff period and discharge it in a peak period. GoodWe's manual says to use it only where local rules allow. Whether it is worthwhile depends on your tariff.
Yes. GoodWe's battery warranty supports capacity expansion with no limit on the production date of added modules, and module sizes can be mixed up to 12 modules or 108 kWh. GoodWe notes that battery heating is unavailable in mixed stacks and that expansion needs BMS and DC-DC firmware V06 or later. After an expansion, the system should run one full charge and discharge cycle.
Up to 12 modules per system, for up to 108 kWh with 9.0 kWh modules, and up to six in one column. Module sizes are 5.12, 6.0, 8.32 and 9.0 kWh, and they can be mixed.
