The GoodWe Three-Phase ESA All-in-One energy storage system has officially received Clean Energy Council (CEC) approval, clearing the way for Australian homes and businesses to access one of the most versatile battery storage solutions on the market. Stock is expected to arrive from late March to early April 2025, and we’re excited about what this system brings to the table.
ESA overview
- All-in-one design with massive scalability for single and now three-phase power supplies. The ESA combines an inverter, an LFP battery, and energy management into a single pre-wired unit, with storage scaling from 5 kWh to 108 kWh, meaning it can be right-sized for a family home today and expanded later as energy needs grow.
- Optional whole-site backup with near-instant switchover. The system provides full backup for homes and businesses, with a switchover time of under 4 milliseconds, keeping essential equipment running without interruption during grid outages.

CEC approval is the benchmark for renewable energy products in Australia. It confirms the system meets strict Australian safety, performance, and quality standards — and it means accredited installers like PSW Energy can confidently design and install the ESA knowing it complies with all regulatory requirements. For homeowners and business owners, it provides peace of mind that your investment is backed by rigorous independent testing.
A complete energy solution
The GoodWe ESA takes a different approach to energy storage by combining the inverter, high-voltage lithium iron phosphate (LFP) battery, and intelligent energy management into a single pre-wired unit. Rather than piecing together separate components, the ESA arrives as one integrated system — which means faster installation, fewer potential points of failure, and a cleaner setup on your property.
Designed specifically for three-phase connections, the ESA suits larger homes, rural properties, and small commercial premises where single-phase systems simply can’t keep up with demand.
Power and storage that scales
One of the standout features of the ESA is its flexibility. The system is available from 5 kW through to 29.9 kW of inverter capacity, with battery storage starting at 5 kWh and scaling all the way up to an impressive 108 kWh using a modular, stackable battery design.
What does that mean in practical terms? Whether you’re powering a four-bedroom home with a pool and electric vehicle charger, or running a small workshop or retail premises, the ESA can be sized to match your energy consumption today — and expanded later as your needs grow. It also supports significant solar oversizing, so you can pair it with a larger solar array to maximise self-consumption and storage.
Optional whole-site backup
Power outages are an increasing concern across Australia, whether from storm damage, grid instability, or planned maintenance. The GoodWe ESA provides whole-home or whole-site backup capability with an ultra-fast switchover time of under four milliseconds. That’s essentially instant — your lights, fridge, internet, and essential equipment stay running without interruption.
For rural properties and businesses where grid reliability can be inconsistent, this level of backup protection offers genuine energy independence and operational continuity.
Why three-phase matters
Many larger Australian homes and most commercial premises operate on three-phase power. If your property has three-phase supply, you need a compatible storage system to properly manage energy across all phases. The ESA is purpose-built for this, delivering balanced power and the capacity to handle higher demands from multiple air conditioning units, EV chargers, or commercial equipment.
