The three-phase GoodWe ESA cleared Clean Energy Council approval in March 2026, which matters most to a group of people who are not shopping for a battery at all: owners of the GoodWe EH, EHB and ET hybrids it replaces. If you have one of those, the more urgent page is the recall notice on the error-code reference.
In short
- Three-phase ESA is CEC-approved as of March 2026. Inverter capacity from 5 kW to 29.9 kW, storage stacking from 5 kWh to 108 kWh.
- The single-phase ESA has been on sale in Australia since October 2025.
- It succeeds the GoodWe EH, EHB and ET hybrids paired with Lynx Home batteries. Those are legacy now — we still support them, we no longer fit them.
- CEC product approval is a listing for equipment, not an installer credential. It confirms the unit may be installed here; it says nothing about who is installing it.
The ESA system
Inverter, high-voltage LFP battery, energy management and backup switchgear in one pre-wired enclosure, rather than four components on a wall talking to each other over a comms cable that someone has to get right. Storage stacks in modules, so the same product covers a small home and a workshop.
The three-phase version is the part that was missing. Larger Perth homes and most small commercial premises run three-phase, and a single-phase battery on a three-phase property can only work on one leg of it — which is why the backup circuit ends up covering the fridge and not much else. A purpose-built three-phase unit manages across all three.
New installations and existing owners
Three groups. Anyone on three-phase who has been told a battery is awkward on their property: it is less awkward now. Anyone weighing whole-site backup on a rural block or a business where an outage costs money, where the sub-four-millisecond switchover is quick enough that most equipment never notices. And GoodWe owners with an EH, EHB or ET hybrid, because this is the product line their system's replacement path now runs through.
That third group should read the recall notice first. GoodWe EHB and GE-branded GEH inverters sold in Australia between 3 May 2021 and 4 September 2025 are subject to an ACCC recall over an export hazard through the bypass switch, fixed by firmware. It is not a reason to replace the system and it is a reason not to use the bypass switch until the update is applied.
Review status and sizing limits
We are not putting a price on it here and we have not finished our own model-family review, which is what has to happen before it goes into our compatibility engine with real evidence behind it rather than a datasheet summary. A manufacturer's specification is a starting point for that work, not the end of it.
Scaling to 108 kWh also deserves a caveat: almost no home needs it. That figure describes what the architecture allows, not what anybody should buy. A battery is sized against evening load and the shape of your bill, and on most Perth houses the honest answer sits between 10 and 20 kWh however far the stack could go.
If you are on three-phase and working out whether storage is worth it, start with adding a battery to an existing system, or ask for a written price and we will size it against your own consumption rather than the maximum on the brochure.
