CEC approval secured for GoodWe’s three phase ESA all-in-one energy storage system

GoodWe Australia is proud to announce that its new Three-Phase ESA All-in-One energy  storage system has received Clean Energy Council approval, making way for installations  across the country from late March/early April. The Three-Phase ESA joins the Single-Phase  ESA, extending GoodWe’s All-in-One energy storage range for Australian homes. 

Designed specifically for homes and small to medium businesses with three-phase power,  the ESA integrates a solar inverter, high-voltage battery, and intelligent energy management  system into a single unit. With inverter capacity from 5 kW to 29.9 kW and 5 kWh to 108  kWh of storage, the Three-Phase ESA offers substantial flexibility for a wide variety of  energy needs. 

Traditional battery systems often require separate components installed across multiple  locations. The ESA’s pre-wired, modular design combines everything into one enclosure,  simplifying installation, reducing commissioning time, and lowering the risk of compatibility  issues.

Built using lithium-iron-phosphate battery chemistry, the system prioritises safety, durability,  and long-term performance. Multiple layers of protection and advanced arc-fault detection  and fire suppression technology further enhance safety for households and businesses. 

Energy independence within reach 

The ESA is ideal for properties seeking to reduce electricity bills, increase energy  independence, and maintain power during grid outages. 

“We are pleased to add the Three-Phase ESA to our robust lineup of energy storage  solutions, further solidifying GoodWe as one of Australia’s leading battery manufacturers,” said Dean Williamson, Country Manager for GoodWe Australia and New Zealand. “The  expanded solar production and storage capacity for three-phase dwellings and buildings  offers energy independence to those looking to drastically reduce or eliminate energy bills.”  

A key advantage of the ESA platform is its scalability. Storage capacity can be expanded  over time by adding battery modules, allowing customers to start with a smaller system and  increase capacity as needs grow. This is particularly useful for households planning future  electrification, electric vehicle charging, or increased energy consumption. 

The system is also designed to provide whole-home backup, automatically switching to  stored energy almost instantly when the grid fails. This capability is increasingly valuable as  extreme weather events and network constraints lead to more frequent outages in some  regions. 

In addition to backup protection, the ESA features intelligent energy management designed  to optimise how energy is generated, stored, and used. The system can prioritise solar self consumption, charge during cheaper off-peak periods, and reduce reliance on expensive  peak electricity. 

Expanded flexibility for more applications 

The three-phase design makes the ESA especially suitable for larger homes, rural  properties, workshops, and commercial premises that require higher power output than  single-phase systems can deliver. It also supports both grid-connected and grid outage  conditions, with the ability to run multiple units in parallel for larger installations. 

High efficiency and strong solar input capability allow users to capture more energy during  daylight hours and use it when needed most. This helps maximise the value of rooftop solar  systems and reduces dependence on grid electricity. 

CEC approval confirms that the system meets Australia’s stringent safety and performance  requirements, allowing customers to access applicable rebates and incentives where  available. 

As Australia accelerates toward electrification and renewable energy adoption, integrated  storage solutions like the ESA are becoming essential. Rising energy costs, growing solar uptake, and increasing demand for reliability are driving interest in larger, smarter battery  systems. 

GoodWe’s Three-Phase ESA All-in-One aims to meet this demand with a scalable, future ready solution capable of supporting homes and businesses for years to come. 

The CEC-approved Three-Phase ESA All-in-One will be available through authorised  installers nationwide, with stock expected to be available from mid-March via GoodWe  distributors. 

Amber integration 

With beta testing in its final stages, homes looking to benefit from wholesale energy market  trading with Amber will soon be able to capitalise on extended savings with the ESA series.  More information will be available soon.
