The GoodWe ESA 10kW All-In-One System
Video Source: GoodWe
At Fusion Sun Solar, we know that Perth homeowners are not just looking for a battery, they are looking for a complete energy infrastructure that can handle the demands of a modern, high-usage household. If you have got a large family, ducted air conditioning, a pool, or an EV on the way, the GoodWe ESA 10kW All-in-One System is the heavyweight champion you have been waiting for.
Known as the "Power Tower," this system replaces the messy "science experiment" of separate boxes and conduits with a single, sleek, IP66-rated cabinet that integrates your inverter, high voltage batteries, and backup switchgear into one unit.
Which Size Do You Need?
Choosing the right battery capacity is about balancing your daily energy "diet" with your goals for independence. Since the GoodWe ESA system is modular, you can start with what you need today and grow later, but here is a quick guide to help you find your starting point based on typical Perth energy habits:
- 16kWh (2 Modules) - The "Evening Essential": Ideally suited for entry-level setups or smaller homes. This size is designed to bridge the "Solar Cliff", covering your power needs from sunset through the evening (TV, lights, cooking) so you are not buying expensive peak hour electricity from the grid.
- 24kWh (3 Modules) - The "Average Family" Standard: This is the "Goldilocks" size for the typical Perth family home. It provides enough storage to handle standard overnight loads, including the fridge and various standby appliances, with a comfortable buffer for those days when the kids leave every light in the house on.
- 32kWh (4 Modules) - The "Lifestyle Pro": Do you have a pool pump that runs daily or an EV (Electric Vehicle) that needs a top-up? This configuration is built for households with higher than average daytime production and significant overnight consumption. It ensures you have enough "juice" in the tank to keep the lifestyle luxuries running without a bill.
- 40kWh (5 Modules) - The "Heavy User / Home Business": Designed for large households, home businesses, or "heavy users". If you run ducted air conditioning frequently or operate power hungry equipment during the day and night, the 40kWh stack provides the massive storage required to maintain 24/7 energy independence.
Installer Tip: Keep in mind that as you go up in size, the weight increases significantly. A 40kWh setup weighs approximately 412kg. Because of this "monolith" weight, it must be installed on a reinforced concrete slab or plinth to ensure it stays safe and level for its 10+ year lifespan.
Is your home ready for 10kW of Power?
Open your last Synergy or Western Power bill. If your daily consumption is high and your roof is covered in panels, the 10kW system is your "Goldilocks" solution.
- Do you have a complex roof? The 10kW unit features up to 4 MPPTs, allowing you to place panels on North, East, West, and South faces without needing expensive microinverters.
- Worried about Blackouts? This system features 63A internal bypass passthrough, meaning it can back up your entire home (within power limits) without requiring extra gateway hardware.
- Compliance Trick: While it is a 10kW powerhouse, it is often rated at 9.999kW to fly through Perth DNSP residential approval processes, avoiding the months of delays and fees associated with commercial grade connections.

Comparing the Battery Packages (16kWh, 24kWh, 32kWh, 48kWh)
In Perth, the 10kW system is typically paired with these four massive storage configurations. These stacks are built using high voltage (HV) modules, which run cooler and more efficiently than older 48V technology.
| System Capacity | 16kWh Setup | 24kWh Setup | 32kWh Setup | 40kWh Setup |
|---|---|---|---|---|
| Number of Modules | 2 Modules | 3 Modules | 4 Modules | 5 Modules |
| Usable Energy | 16.0 kWh | 24.0 kWh | 32.0 kWh | 40.0 kWh |
| Battery Type | LFP (Safe Chemistry) | LFP | LFP | LFP |
| Charge/Discharge Rate | 1C (Rapid cycling) | 1C | 1C | 1C |
| Total System Weight | ~175 kg | ~254 kg | ~333 kg | ~412 kg |
The Heart of the System: GW8.3-BAT-D-G20 Module
Each individual "brick" in your tower is a masterpiece of safety and performance:
- Rapid Energy Cycling: The 1C rate means that on a sunny Perth day, your 16kWh stack can charge from empty to full in roughly two hours.
- Safety First: Every module includes integrated aerosol fire suppression and six layer protection.
- Built-in Heating: If you live in the Perth Hills, the integrated heating mode ensures your battery warms itself up on frosty mornings so it stays efficient all year round.
Perth Installation Essentials
Because a fully loaded 40kWh "Power Tower" can weigh over 400kg, it cannot sit on standard pavers or timber decking. At Fusion Sun Solar, we ensure your system is installed on a reinforced concrete slab or plinth for maximum stability.
Take Control with Fusion Sun Solar
By choosing the 10kW ESA system, you are essentially installing your own "Private Substation". You will also be eligible for the WA Residential Battery Scheme, which currently offers a point of sale discount of $130 per usable kWh (up to 10kWh) if you join an approved VPP.

Frequently Asked Questions
For Perth residents considering the GoodWe 10kW ESA All-in-One system, understanding specific local factors including Western Australian rebates, our unique environmental conditions, and regional product availability is essential. As your trusted local solar experts, Fusion Sun Solar has tailored these answers specifically for our WA community.
Why is the 10kW inverter technically listed as "9.999kW"?
This is a strategic "compliance trick" designed for the Australian market. In many Western Australian networks, connecting an inverter at exactly 10kVA or higher can trigger complex "Level 2" commercial application processes, which involve months of delays and expensive engineering fees. By rating the GoodWe ESA inverter at 9.999kW, it fits strictly within the "Residential" approval tier, allowing it to fly through local DNSP approval processes while still delivering maximum power.
Can this 10kW system back up my entire Perth home during a blackout?
Yes, the GoodWe ESA is built for whole home backup. It features an internal 63A bypass passthrough, which is sufficient to run standard household loads, including air conditioning, lighting, and refrigeration simultaneously. The system offers UPS grade switching in less than 4ms to 10ms, meaning your lights and appliances will stay running without a flicker.
What rebates are available for Perth residents installing this system?
How fast will the 10kW system charge my batteries?
The system features a 1C charge/discharge rate, which is exceptionally fast for residential storage. This means that on a sunny Perth day, a 16kWh stack can theoretically charge from empty to full in roughly two hours, provided your solar array is large enough. The 10kW inverter allows for 200% PV oversizing, meaning you can connect up to 20kW of solar panels to ensure your batteries hit 100% even on cloudy days.
Is the 40kWh system too heavy for my garage floor?
Weight is a critical consideration for large ESA setups. Each individual battery module weighs 79kg, and the 10kW inverter weighs approximately 17.7kg.
- A 16kWh setup weighs ~175kg.
- A 40kWh setup weighs approximately 412kg. Because of this "monolith" weight, the unit cannot be installed on timber decks or standard pavers, it requires a reinforced concrete slab or plinth to remain safe and level.
How does the system handle Perth extreme weather?
The ESA series is IP66-rated, making it dust tight and protected against powerful water jets, which is ideal for WA's dusty summers and winter storms. For residents in cooler areas like the Perth Hills, the system includes an integrated heating mode that allows the battery to maintain a full 1C charge/discharge rate even in temperatures as low as -20°C.
