Key Points
- The GoodWe ESA Series is a fully integrated all-in-one solar battery — inverter, storage, and energy management in a single unit
- Now available in three-phase, making it suitable for larger homes, new builds, and small commercial properties
- Modular design allows you to start from 5kWh and expand up to 48kWh as your energy needs grow
- Uses Lithium Iron Phosphate (LFP) chemistry — the safest and most thermally stable option for Australian conditions
- Supports whole-home backup with rapid switchover during grid outages
- Federal battery rebates are stepping down from May 2026 — installing sooner locks in the higher rebate level
For years, the biggest challenge in the solar and battery industry hasn’t been performance—it’s been complexity. Homeowners have had to deal with multiple boxes, complicated commissioning steps, and numerous potential points of failure.
The GoodWe ESA Series changes that. It’s not just another solar battery; it’s a fully integrated, all-in-one energy storage system that represents a major step toward what residential energy systems are meant to be: simple, scalable, and built for real homes.
A True All-In-One Solution for Modern Homes
The GoodWe ESA Series combines the solar inverter, battery storage, and an intelligent energy management system into a single, pre-wired unit. This design simplifies installation, reduces component complexity, and improves long-term reliability.
Traditional solar battery installations often require separate inverters, external battery cabinets, backup interfaces, and extensive wiring between components. The GoodWe ESA eliminates this by integrating everything into one compact, wall-mounted unit that arrives pre-wired and ready to install.
Now Available in Three-Phase
One of the most significant recent developments is the approval of the GoodWe ESA three-phase battery for the Australian market. Three-phase power is common in larger homes, new builds, and small commercial properties—and until recently, the options for all-in-one battery systems in this space were limited.
The three-phase ESA brings the same integrated design and scalability to properties that previously had to rely on more complex, multi-component setups. It’s now available through authorised installers including Solar Set.
Flexibility That Grows with Your Home
The ESA Series is built around a modular architecture. Homeowners can start with a 5kWh or 8kWh module and add capacity over time—stacking up to six modules for a maximum of 48kWh in a single system. This approach makes the GoodWe ESA accessible at a lower upfront cost while leaving room to expand as energy needs change or as EV adoption increases.
The system is also designed with EV charging integration in mind. As electric vehicles become more common in Australian households, the ability to intelligently manage solar generation, battery storage, and EV charging from a single platform will become increasingly valuable.
Designed for Real-World Performance
The GoodWe ESA uses Lithium Iron Phosphate (LFP) battery chemistry—widely regarded as the safest and most stable chemistry available for residential energy storage. LFP batteries offer excellent thermal stability, a long cycle life, and consistent performance across a wide range of temperatures, making them well-suited to the Queensland climate.
The system supports whole-home backup with rapid switchover, meaning that in the event of a grid outage, essential circuits remain powered with minimal interruption. This is particularly relevant on the Gold Coast and surrounding areas, where summer storm season can bring unexpected outages.
Why Installation Quality Matters
Even the best battery system will underperform if it’s not installed correctly. The GoodWe ESA requires careful system design—particularly around backup circuit configuration, switchboard compatibility, and network commissioning. Solar Set’s team are accredited and experienced installers who handle the complete process from design through to commissioning and ongoing support.
Quiet, Compact, and Built for Homes
The ESA Series is designed to sit comfortably in a garage, utility room, or on an external wall. It operates quietly, has a clean aesthetic, and its compact footprint means it doesn’t dominate the space it’s installed in. The integrated display provides at-a-glance system status, and the GoodWe SEMS portal gives homeowners full visibility of their energy flows from any device.

Important Note on Battery Rebates
Federal battery rebate structures are stepping down from May 2026 as battery costs continue to fall. The rebate factors used to calculate government support will reduce, meaning the total rebate available on larger battery systems will be lower as the year progresses. Homeowners who install before the step-down lock in the current, higher rebate level. The modular GoodWe design also means you can start with a smaller system today and expand later without losing your rebate entitlement on the initial installation.
Why We Recommend the GoodWe Battery Platform
Solar Set has been installing GoodWe products across the Gold Coast, Brisbane, and Sunshine Coast for several years. The ESA Series represents the most complete and installer-friendly battery platform we’ve worked with. The integrated design reduces installation time, the modular architecture gives customers genuine flexibility, and GoodWe’s local support and warranty backing gives us confidence in recommending it to our customers.
