Media Release
GoodWe has unveiled its ESA Series, a powerful all-in-one solar and battery solution designed for residential homes and small businesses across Australia. Compact, intelligent, and incredibly safe, the ESA offers plug-and-play convenience with whole-home backup built straight in.
Built for safety and simplicity
Safety sits at the heart of the ESA’s design. Featuring six layers of battery protection, AI-driven AFCI 3.0 (Arc Fault Circuit Interruption), and a fully sealed IP66-rated enclosure, the ESA delivers peace of mind for households and installers alike.
Its fanless cooling system keeps operational noise below 30 decibels, making it ideal for indoor or outdoor installation. Together, these protections position the ESA as one of the safest and quietest energy storage systems in its class.
“Australians are looking for energy solutions that are powerful yet simple,” said Dean Williamson, Country Manager for GoodWe Australia. “The ESA takes the guesswork out of solar and battery pairing while providing full home backup right out of the box.”
Unlike many hybrid systems that rely on additional gateways or accessories, the ESA provides 63 amp full-home backup capability from day one. Acting as a true uninterruptible power supply (UPS), the ESA ensures a seamless switchover during outages to keep lights, fridges, and essential appliances running.
Its integrated inverter supports 2–4 MPPTs (maximum power point trackers) and allows for 200 per cent PV oversizing, giving households the flexibility to make the most of rooftop solar throughout the day.
Modular power for every stage of the journey
The ESA isn’t just built for now, it’s built for what’s next. Available in 3–10 kW inverter options, it can be paired with modular 5 kWh or 8 kWh batteries, which are scalable up to 48 kWh per stack, with a maximum of 6 stacks in parallel.
A 1C charge and discharge rate ensures faster cycling and better solar utilisation. The ability to mix old and new battery modules lets homeowners expand capacity over time without replacing existing units.
Whether you’re running a family home, a home office, or a small business, the ESA adapts to changing needs with ease.
Designed for installers and homeowners alike
The ESA’s integrated architecture dramatically reduces installation time and wiring complexity. With dual output ports and flexible mounting options, it’s a practical solution for both new builds and retrofits.
Installers benefit from GoodWe’s intuitive commissioning app, while end users gain real-time visibility and smart control via the GoodWe SEMS portal and app, making energy management simple and transparent.

Empowering Australia’s clean energy transition
As electricity prices climb and reliability becomes a household concern, GoodWe’s ESA provides a complete, scalable path toward energy independence. Its combination of safety, flexibility, and full-backup capability makes it a standout in Australia’s fast-growing battery market.
“This is what the future of home energy looks like: simple, safe, and smart,” Williamson added. “The ESA gives Australians the confidence to take control of their power.”
The Clean Energy Council-approved ESA is eligible for the Cheaper Home Batteries Program.
