Take Control of Your Energy with the GoodWe ESA
All-In-One Solar & Storage System
Seamless whole-home backup, elegant modular design, and absolute blackout protection, installed by the local experts at SAE Solar.
Rising electricity prices and unpredictable grid outages shouldn't dictate your lifestyle.
At SAE Solar, we believe true energy independence should be simple, beautiful, and completely reliable. That’s why we are proud to supply and install the next generation of home energy management: the GoodWe ESA All-in-One Energy Solution.
Combining a high-efficiency solar inverter and state-of-the-art battery storage into a single, pre-wired elegant tower, the GoodWe ESA Series eliminates messy cabling and complex setups. Whether you want to wipe out your daily power bills, capitalise on smart time-of-use pricing, or guarantee your home stays powered through the worst storms, the GoodWe ESA Series is the ultimate all-in-one answer.
Why Choose the GoodWe ESA Series?
The GoodWe ESA Series is a premium, fully integrated solar-plus-storage system explicitly engineered for Australian homes. Designed with ultimate flexibility in mind, the modular system accommodates both standard and high-capacity households by offering both single-phase and powerful three-phase hybrid inverter configurations. Whichever option suits your property, it pairs intelligent energy management with ultra-reliable Lithium Iron Phosphate (LiFePO4) battery modules.
Because it utilises a clean, blind-plug stacking design, it installs significantly faster than traditional split systems, saving you time and deployment footprint. Starting with a base capacity of 5kWh or 8kWh, the ESA system effortlessly expands up to 48kWh in a single stack to match your home’s evolving energy appetite as your family grows – providing a future-proof solution for both single-phase and three-phase properties.

Why Homeowners Love
the GoodWe ESA Series
Investing in solar is a smart first step, but true energy independence comes down to how effectively you can store, manage, and protect that power. The GoodWe ESA Series isn’t just a battery – it’s a complete upgrade to your lifestyle, financial freedom, and home aesthetic.
Here is how the ESA series transforms your daily energy experience:
Slash Your Power Bills Forever
Maximise your self-consumption by storing abundance daytime solar generation to run your home at night, completely bypassing expensive peak retail tariffs.
Instantaneous Blackout Immunity
Enjoy peace of mind knowing that when the neighbourhood grid fails, your entire home transitions to battery power so fast you won’t even realise the power went out.
Future-Proof Scalability
Never worry about buying the "wrong size" battery. The ESA series allows you to easily stack additional modules later on, and uniquely supports mixing new batteries with older modules seamlessly.
Rapid Energy Recovery
Supports a powerful 1C charge and discharge rate, meaning the battery system can rapidly cycle energy - perfect for charging quickly when the sun breaks through or supporting high-surge household appliances.
Maximum Solar Capture
With support for up to 200% PV oversizing and dual input strings per MPPT, you can oversize your rooftop solar array to ensure your battery charges even on dark, overcast winter days.
Total Visual Discretion
Housed in a beautifully sleek, premium gloss white finish tower with zero exposed conduit or chaotic wiring clusters, it complements your garage or external wall like a piece of high-tech home appliance luxury
Smart Energy
Operating Modes
The GoodWe ESA system doesn’t just store power – it thinks for you.
Through the intelligent SolarGo App, you can configure your system to run on several intuitive modes:
Self-Use Mode
Automatically prioritises your solar generation to run your appliances first, charge your battery second, and export any leftover bounty to the grid.
Time-Of-Use (TOU) Mode
Explicitly instructs the battery to charge from the grid when rates are cheap (off-peak) and discharge to run your home when grid pricing spikes.
Peak Shaving Mode
Monitors total load consumption to ensure you never exceed grid power limits, discharging the battery to absorb heavy load demands seamlessly.
