Official GoodWe product film
One tower. Everything prewired.
Inverter, battery modules and backup arrive as one pre-wired system, which is exactly why installs are cleaner and faster on the day.
- Pre-wired inverter, battery and backup in one cabinet
- 3–10 kVA nominal off-grid output by inverter model; 63 A is maximum grid bypass
- 2–4 MPPTs, 20 A per string and up to 200% PV oversizing
- Heating mode rated to -20°C, IP66 for outdoor walls
Size it to the house
Stack the capacity you actually need.
The ESA family uses several battery module models with different usable capacities. Mixing, stacking and expansion must follow the compatibility rules for the exact inverter and battery models.

Module choice
Usable module capacities and compatibility depend on the selected GoodWe battery model.

Stack design
The written quote should list each module model and the resulting nominal and usable capacity.

5–108 kWh family
GoodWe's family capacity is configuration-dependent; it is not a universal single-stack limit.
If later expansion is planned, check compatibility, warranty and the federal program rules at that time. Added capacity is only eligible where the existing system has not previously received the program discount and all current criteria are met.
What stands out
Published features, tied to the exact model.
Fast energy cycling
Published charge and discharge limits depend on the compatible inverter and battery configuration selected for the job.
Mix and expand
The Australian datasheet lists 5.0, 8.0, 5.8 and 8.7 kWh usable module options, with mixing and stacking rules tied to compatible models.
Documented protection
GoodWe documents LFP modules, battery management and integrated aerosol fire suppression. Inverter protection features depend on the selected model.
Quiet and weatherproof
The range is IP66. Published noise is no more than 30 dB for 3–6 kW models and no more than 35 dB for 8–10 kW models.

Configuration checks
When the ESA can fit.
- Fit: single-phase properties where an ESA inverter variant matches the proposed solar and site supply
- Fit: three or four 8 kWh usable modules (24 or 32 kWh usable)
- Limitation: off-grid output is 3–10 kVA by inverter model; nominated circuits must fit it
The written configuration comes first.
Confirm the precise inverter and battery models, nominal and usable capacity, backed-up circuits, off-grid continuous and surge output, phase and component warranties.
The decision
What it costs, plainly.
Get an instant GoodWe price in our estimator — from 16 to 48 kWh, single or three phase — with rebates taken off. A free site check confirms switchboard, metering, backup circuits and cable route.
GoodWe's 63 A figure is maximum grid bypass on relevant models. It is not 63 A of battery-only output and does not by itself establish whole-house backup. The inverter's off-grid kVA rating, surge requirement and nominated circuits set the backup design.

Battery warranty
Product: 10 years — GoodWe AU ESA 3–10 kW warranty lists the G20 8.3 kWh module. Performance: 70% usable energy within 10 years, or 29.20 MWh minimum throughput per 8.0 kWh module, whichever comes first (subject to terms). Inverter: 10 years for the named G20 ESA 3–10 kW single-phase inverters. Extension: None published.

Newcastle & Hunter installation
The technology is global. The accountability is local.
Every ESA we fit is designed and installed by our own electricians out of Hamilton — licence 470217C. No subcontractor hand-off, from switchboard assessment through to commissioning.

Common questions.
01What does the 63 A figure mean?
It is the maximum grid bypass current on relevant models, not battery-only output. Off-grid output is 3 to 10 kVA depending on inverter model.
02How many modules should I install?
Newy quotes three or four 8 kWh usable modules. Bills, interval data, solar production and required backup duration decide the count.
03Does it run the whole house in a blackout?
Not automatically. The inverter's continuous and surge output and your simultaneous loads decide which circuits are backed up.
Not sure it is the right fit?
Compare the other systems.
